Forum d’assistance Firefox

CVE-2024-4367 has been announced several days now with MITRE and CIS. There is also an issue/advisory on the github repo for PDF.js which appears that the fix has been merged into the master commit of PDF.js (https://github.com/advisories/GHSA-wgrm-67xf-hhpq).

The vulnerability is pretty serious and yet there is no Security Advisory from Mozilla on affected versions, etc. (https://www.mozilla.org/en-US/security/advisories/)

Is this normal and I am just being impatient?

I am trying to configure Firefox on macOS to not prompt the user to make it the default browser.

I am using the following script to create the profile and set the user preferences after installing Firefox by copying `Firefox.app` from the downloaded DMG: ```

1. !/bin/sh

open -a Firefox.app --args -CreateProfile default sleep 1

write_userpref() { USER=$(whoami) PROFILE=$(ls -1 "/Users/${USER}/Library/Application Support/Firefox/Profiles/" | grep -E "\.default$") cat << EOF > "/Users/${USER}/Library/Application Support/Firefox/Profiles/${PROFILE}/user.js" // mandatory comment? user_pref("app.update.auto", false); user_pref("app.update.disable_button.showUpdateHistory", false); user_pref("app.update.enabled", false); user_pref("breakpad.reportURL", ""); user_pref("browser.newtabpage.activity-stream.feeds.topsites", false); user_pref("browser.newtabpage.activity-stream.feeds.section.topstories", false); user_pref("browser.tabs.crashReporting.sendReport", false); user_pref("browser.discovery.enabled", false); user_pref("browser.defaultbrowser.notificationbar", false); user_pref("browser.shell.checkDefaultBrowser", false); user_pref("browser.shell.didSkipDefaultBrowserCheckOnFirstRun", false); user_pref("browser.shell.skipDefaultBrowserCheckOnFirstRun", true); user_pref("browser.newtabpage.enabled", false); user_pref("experiments.enabled", false); user_pref("extensions.pocket.enabled", false); user_pref("toolkit.telemetry.enabled", false); user_pref("update_notifications.enabled", false); EOF }

write_userpref

open -a Firefox.app --args -new-tab -P default "about:blank" sleep 3 osascript -e 'quit app "Firefox"' sleep 2

open -a Firefox.app --args -P default about:blank ```

Here's the behaviour I'm seeing:

1. Firefox starts to an `about:blank` tab, however there is a second "Firefox Privacy Notice" tab
2. AppleScript quits Firefox
3. Firefox starts to an `about:blank` tab, however it is now prompting me to make it the default browser

I do not want Firefox to prompt the user to become the default browser.

My ideal scenario is that Firefox starts without the "Firefox Privacy Notice" tab and without prompting me to make it the default browser. From the observed behaviour, this doesn't seem possible.

Can anyone tell me how I can accomplish this without user interaction or MDM?

Hi,

I am encountering an issue where Firefox throws an "Uncaught out of memory" error in the console, despite my system having ample RAM available. Here are the details of the problem:

• Error Message in Console: Uncaught out of memory
• Memory Usage Observed: Using about:processes, I noticed that Firefox's maximum memory usage caps at around 7GB.
• System Specifications: The machine running Firefox has 128GB of RAM, so there should be plenty of memory available.
• Firefox Version: 126.0a1

Given the significant amount of RAM available on my machine, it seems unusual that Firefox would hit a memory limit at just 7GB. I suspect there might be a bug or a misconfiguration causing this issue.

Can you please assist in diagnosing and resolving this problem? Are there any settings or configurations I should adjust, or is this a known issue with the current version of Firefox?

Thank you for your help.

I have a new PC running Kubuntu 22.04, with Mozilla Firefox 120.0.1 (64 bit) installed. Standard, the system window title bar was hidden. But I wanted access to the "Move to desktop" menu and wanted the title in the title bar. So, in "Customize toolbar" I checked "Title bar". The title bar reappeared, but a complete border along the Firefox window became inaccessible, and when clicking in that zone, it effectively clicked in the window behind. In particular, the complete menu bar is inaccessible, as well as the scroll bar on the left and in the bookmarks sidebar the fold/unfold. And Mozilla Thunderbird 115.5.0 has the same annoying behaviour. Even when hovering over some menus in the Mozilla window, you can sometimes see reactions from the window under the Mozilla window. On older Kubuntu computers (up to 18.04) with older versions of Firefox (up to 113.0.2) and Thunderbird (up to 102.11.0) I do not have that problem. How can I get at the same time access to both the system title bar and the menu bar ?

Hello all...

This one has been driving me a bit batty as of late. I tend to use lots of extensions/add-ons and for most of them, I want the icons to show on the tool bar - that is, the part to the right of the URL/search bar. It used to be that you could adjust the size of your URL/search bar to make it smaller so that more add-on icons could be displayed - but as of recently, that is no longer possible (at least from what I can gather). Right now, I only have 10 add-on icons showing to the right of my URL bar and I have no clue how to access the other add-ons/extensions that I would like to use.

If I can recall correctly, at one time there was a way to show the additional extension/add-on icons in something called an overflow bar - but I can no longer find that, and half of the add-ons I want to access, I cannot do it because they are no longer shown to the right of the URL bar (except for the 10 that are there now).

So my questions are:

How can I resize the URL/Search bar to make it smaller width-wise, so that perhaps, more add-on icons will show to the right - and/or how can I access the rest of my add-ons if they are hidden in some kind of overflow bar?

I have included a screen shot on my current view, showing the add-on icons (some of them) that show to the right of the URL bar - but I have at least 10 others that I cannot find anywhere and would like them to show also.

Thanks in advance...

Hello,

I have tried to download the newest VDH Companion App (via the link on the github.com webpage) Seven (yes, 7) times and every time the download Fails or I get "Zero bytes". I tried to contact "Support" but there is only a Support Forum and nobody else has posted this as an issue that I was able to find when I searched. So no support is offered. The website suggests that I create an account to be able to post a new issue. However, Every time I have tried to set up a github.com account, I am Unable to do so. The page to set up an account either doesn't load OR if it loads, I can not add any information to it. I am a VDH Registered User and until this morning, the current VDH app I am using, version 8.2.1.1 was working just fine. But now when I try to use it, it says that my VDH Companion App needs to be updated. But I can not even download it to update it. I am running the current version of FF, 123.0.1 on an iMac with Sonoma OS 14.4. We used to be able to email Mig but not anymore. The github.com support page is unwieldy at best and I see that numerous requests for help or support have not been answered or even acknowledged. I am a paid Registered user with a license, but that doesn't seem to matter. I, like many others from what I read online, count on using this app almost every day and I would think that the mechanism for updates should be working correctly. The update files I tried to download came across at crazy low speeds, like 20.1 to 40.5 Kbps! I spent over an hour with Tech Support for HughesNet and much to my chagrin, No Other Websites had any issues with download speed. It was only happening on the github.com website and this one file update. Sorry if TMI but I am just trying to thorough.

Is it possible to change Firefox's default keybinds? I don't see an option for this in Settings, nor in about:preferences or about:config. Some discussions on these forums suggest autoconfig.conf but that doesn't seem to have any options for keybinds. I found several KB articles on customizing Firefox, but none said anything about default keybinds:

KB: Customize Firefox controls, buttons and toolbars KB: Firefox advanced customization and configuration options KB: Customizing Firefox Using AutoConfig

For example, I'd like to change the keybind to open a private window from the default [Shift]+[Cmd]+P to [Shift]+[Cmd]+N. The latter is standard on most other browsers and is in my muscle memory. Is there any way to do that?

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

My Wife's computer - still on Windows 10 - says it can't start Firefox as it is still running, hitting the "close Firefox now" button just returns us to the same screen. I tried to uninstall and reinstall Firefox it tried to do a "reinstall" it says her profile is no longer available, while inconvenient she still should be able to start it up, but it still gives me the same message. that it is still running and needs closed. Trying to "close it doesn't do anything. I have restarted several times and even did a shut down and restart. Nothing seems to work. I assume some "stub" of Firefox is out there in the system/cache making Firefox think it is is still active but I can't find it to shut it down. Where do I need to go to "end task" on this phantom Firefox?

Other information: 1. We have Norton Security software installed, if that matters. 2. The same seems to happening to Thunderbird, but maybe I need to go to another help forum for that? 3. I am entering this issue from my computer that seems to be just fine with Firefox, so can't send browser data as it is irrelevant to the issue (it's on a different computer and install instance.

Hello everyone,

I've been experiencing an issue with my website when viewed on Mozilla Firefox. Some elements seem to be rendering incorrectly or not displaying at all. I've tested the website on other browsers, and it appears to be working fine there. Could someone help me troubleshoot this problem? Any insights or suggestions would be greatly appreciated. Details Website URL: https://greenryenthusiast.com/where-is-the-best-spot-to-spray-starter-fluid-on-a-snowblower/ Description of the Issue: When accessing my website on Mozilla Firefox, certain images and stylesheets are not loading properly. Additionally, the navigation menu appears to be misaligned, overlapping some of the content on the page. This issue is consistent across multiple pages of the website. Steps Taken to Resolve the Issue: I've tried clearing the browser cache and cookies, as well as testing the website on different devices and networks to rule out any local issues. However, the problem persists only on Mozilla Firefox. Browser Version: Mozilla Firefox version 98.0.1 (64-bit) Screenshots or Error Messages: Attached below are screenshots illustrating the rendering issues encountered on Mozilla Firefox. Additionally, there are no specific error messages displayed; the elements simply fail to load or display incorrectly.

I seem unable to do this, but I should easily be able to, but despite numerous attempts, I can't figure out how. I've finally given up, hence this plea for help.

If you have a solution, please let me know... Thanx in advance.

I'll not divulge my opinions of this FireFox add-on.

Hello, about 1-2 weeks ago a very strange problem occurred - on some pages videos don't play at all or play without a sound. Can anyone help me with this strange situation? For example, every video on youtube.com plays without a problem; on facebook.com every video plays with no sound at all; on some other pages video doesn't play at all. This problem is only with firefox, if I try to open the same videos with another browser everything is fine.

My computer updated with no warning one night, and i lost all personalization and even everything stored in my firefox, the sign ins, passwords, bookmarks, all. is there a way for me to find all that was erased?

What the title says, and unfortunately I'm not sure why. If a theme isn't perfectly looped, it's...really noticeable. And I hate how ugly some themes turn out as a result. I don't want to start sticking my hands directly into firefox's advanced settings, since I don't know much about them and don't want to risk accidentally deleting or messing with something important, but I'd really like to get this fixed somehow... Is it just the themes I'm picking? Are they supposed to all be skewed off to the side? Or is something off with my browser? Maybe my resolution's weird or something...?

Firefox keeps offering to translate websites, your new feature.

I neither want it to, nor do I appreciate ads, because it is simply you advertising your new product.

I have looked at the settings and there are 0 languages for which I've set it so it will offer me to translate and 0 for which it will do. Besides the fact I do speak and read multiple languages; it is not a feature I am interested in.

So when I set it so it will not bug me about it and every time I enter a foreign language site the little pop-up shows; that's some serious unwanted ads and also clearly FAR more tracking than FF is even supposed to be doing.

I have used firefox for nearly 15 years, but I'm honestly wondering if I should find another privacy focused browser One that doesn't spam me with little pop-ups over it's latest ill-conceived stupid feature.

So you could help by actually NEVER-EVER under any fucking circumstances show this stupid translation pop-up UNLESS I put I request it to do so in the settings or at the very LEAST allow me to turn it off.

I am getting to the end of my tether with Firefox. I have used it for years but the increasing issues are driving me to distraction.

It will not display comments on the Daily Mail UK website, The Telegraph UK site and the screen is scrambled if I try to use Ebay Philippines. I am not a computer expert but I have tried to follow other peoples suggestions with no luck.

I cant see the point of persisting with FireFox unless these issues are rectified.

Any suggestions would be very welcome.

ive built a new pc and have a flashing program popup every 10min. upon assistance from a really good pc guy, we've found its a firefox default browser agent with a long code.

its not listed in my scheduled tasks, eyt runs every 10min. only thing close to firefox would be thrunderbird, but iirc, mozilla and thunderbird are not longer the same company. either way. i need this thing to stop running every 10min.

The last Firefox update, 126.0 (64bit), that was installed 2 days ago has caused various website's commentary or forums to not be displayed. For example, Yahoo finance page, attempting to read the "community" section of a particular stock such as Walmart (WMT) nothing is displayed. This happens also on news websites that allow commentary. Google Chrome does display commentary but I don't like using Google.

This is not the first time commentary has not being displayed after an update. Happened a couple of times last year.

The desktop pc is running Windows 11, version 23H2.

Thanks, Frank

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

We still use some Dell 13g servers equipped with idrac 8. When I'm trying to launch the virtual Console the window opens up but nothing shows. This used to work fine in previous versions of Firefox. I can't tell from which version it stopped but it's not long ago. Also idrac 9 console works fine in Firefox When trying to open console idrac 8 in Chrome it works fine Any idea what could be causing it? Any config switch to tweak?
