Firefox Support Forum

Sadly, I am now forced to leave firefox. My passwords are getting "forgotten" more and more each day. Did i get hacked? Few passwords like proton mail I don't actually have anywhere else. Auto-Backup of firefox seems to be of the same day as the original??? So it loses the data then saves it twice? who designed this? I'm angry, not at firefox/mozilla. angry at myself for putting my trust in the first place. Chromium doesn't sync so it leaves me with chrome FFS. Does someone has a magic wand to recover the lost data? login.json is same day as original so not an option.

I am running Firefox 126.0-1 on an Arch Linux system. Most websites are failing to connect for security reasons.

Some sites, including google.com and nytimes.com, fail with an "SEC_ERROR_UNKNOWN_ISSUER" error, and their certificates confirm that they are respectively issued by Google Trust Services LLC and DigiCert Inc.

The website archlinux.org errors with "MOZILLA_PKIX_ERROR_MITM_DETECTED", stating that "Software is Preventing Firefox From Safely Connecting to This Site", citing in particular ISRG Root X1 as the problem. The certificate confirms that it is issued by Let's Encrypt.

The website duckduckgo.com simply errors with "SEC_ERROR_PATH_LEN_CONSTRAINT_INVALID" and states "Secure Connection Failed"

I have confirmed in preferences that my proxy settings are set to "No proxy" and the problem persists across troubleshooting mode and making a new profile. I have also tried removing the cert9.db file in a given profile folder.

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 was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

Hi. i have no results while doing this: https://dpaste.com/FTXPQ46ZL# No error, no screenshot. "Screenshot" flags in default state, about:policies - inactive.

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

After upgrading to fedora 40, firefox just takes ages to boot up, even when it's running if I want to open a new window it still takes ages to run. I have tried uninstalling it and deleting it's data but with no luck. The issue still presists.

I am using the apt version of firefox v125.0.2 (64-bit). I do not have a dedicated GPU - I use my intel core's internal gpu only Intel Corporation HD Graphics 620 (rev 02).

I used to play this game named narrow.one, which before I reinstalled the mentioned libraries, was working fine except for crashing a few times. I thought these libraries were causing some issue, so I tried reinstalling them.

I reinstalled the libraries using: `sudo apt install --reinstall --fix-missing libgl1* libegl*`

After installation, I start getting that error. So, I tried reinstalling firefox (using the same command), and then restarting the laptop - but of no use. Chrome seems to be running WebGL, including the game.

In firefox, on the https://get.webgl.org/ page, I see Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.

After that, I also tried reinstalling `libopengl0` and `libglu1-mesa` and `intel-microcode`, but of no use. Running although, `sudo intel_gpu_top` and then chrome, it seems that the GPU is in use by chrome as well.

I then go to about:support. It shows me the images I have attached. Reading the logs, there several `blocklisted` values in `Decision Log` section. I suspect that's the cause of this issue, but then I don't know how can I un-blocklist the blocklisted things, and even after that, why does Chrome runs webgl if these are blocklisted?

Running `glxinfo -B`, I get the following: `name of display: :0 display: :0 screen: 0 direct rendering: Yes Extended renderer info (GLX_MESA_query_renderer):

   Vendor: Intel (0x8086)

OpenGL ES profile version string: OpenGL ES 3.2 Mesa 23.2.1-1ubuntu3.1 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20`

I do not know much about OpenGL, but reading the above stuff, I suppose my GPU is in use and also has a compatible driver (although I am not sure).

Also, running `glxdemo`, `glxheads`, and `glxgears` seems to be rendering stuff.

Should I reinstall firefox after purging it first? Please help.

Thanks!

The increase happened here: /storage/permanent/chrome/idb/3870112724rsegmnoittet-es.files/

79 files taking 590MB created in 3 minutes, out of nowhere. Why were all these large files created?

Using Linux Mint, Firefox 125.0.2

I want to enable cookies for outlook and google, the rest I dont want.

I have attempted to look at the cookie's url for outlook and add that to the exception list, but outlook still harasses me with its annoying 2fa

How do I find the actual address to put in the exceptions list to stop this issue?

The story is when I accidentally clicked on a sick video, YouTube start to recommend me similar sick videos.

So my question is how does YouTube get my identity?

I'm not logged in. my profile is actually a snapshot, so when I restart Firefox, it go back to the snapshot. I even restarted my ISP router to get a new IP address. This did not work.

Only when I create a new profile with "firefox -P" does YouTube start to see me as a new person.

So how does YouTube identify my Firefox profile? I don't think it's in the https request headers. Weird.

Hi I have been using firefox on linux for a while without updating it. We are artsellers and I used to be able to log in and out of an artplatform without any problems. It's now been a few weeks since logging out is not possible any more on this platform which means that I am constantly logged in which I really do not want. The menu does not work anymore on this side whereas it works with other browers. I already contacted the platform. They cannot do anything about it themselves and asked me to contact your team. Please help. Thank you Best regards from Germany C. Marsac

In Linux Ubuntu I created 4 different launchers for 4 profiles.

Firefox opens the different profiles correctly, but the name of Profile 4 is displayed in the title bar for all windows. This causes confusion when I'm using the different profiles. Furthermore, the icon displayed in the icon bar is also the same for the 4 profiles, although I have configured a different icon for each profile. I ask for help as I need each instance to have its own name and icon displayed correctly.

The launchers look like this:

firefox-profile1.desktop: Name= Profile 1 Exec=firefox -P profile1 --no-remote Icon=~/.local/share/icons/profile1.png

firefox-profile2.desktop Name=Profile 2 Exec=firefox -P profile2 --no-remote Icon=~/.local/share/icons/profile2.png

firefox-profile3.desktop Name=Profile 3 Exec=firefox -P profile3 --no-remote Icon=~/.local/share/icons/profile3.png

firefox-profile4.desktop Name=Profile 4 Exec=firefox -P profile4 --no-remote Icon=~/.local/share/icons/profile4.png

My system broke during an update. Now I want to import my old Firefox userdata, but everytime I try to use the old data firefox just forces the creation of a new profile?

Is it completely impossible to recover data not created with the same firefox version?

Hello Ladies and Gentlemen!

Please read my post completely before answering! Thank you!

I'm using

• Firefox DevEd (manually installed) as my primary driver and
• the standard Firefox (installed from the package manager) for leisure/hobby related browsing

each with its own Mozilla account and profile, on Manjaro KDE. Sadly, either Firefox sees all the profiles. They have usually different versions. If I mistakenly start one of the Foxes in the other Fox's profile, the newer version of Firefox (usually Firefox DevEd) autostarts migrating that profile. Which it renders the profile "corrupted" for its intended Firefox.

I'd like to have Firefox DevEd unable to see profiles (or anything else) intended for the standard Firefox and vice versa. Or at least unable to botch profiles. I do not want to disable migration or use no. Given that Firefox configuration location is hard-coded, I'm not having high hopes for my wish.

I'm wondering if there is a way to keep two Firefox installations completely isolated, other than running them in containers.

Thank you for your time!

I've disabled this for my google account. So when I search from google.com this behavior doesn't happen. But when I type anything into my address bar on Firefox to search, the first suggestions are from my search history.

I don't want to delete my search history.

I often use my search history to find specific things that I need, but didn't bookmark at the time. I need my search history to be saved. I just don't want to automatically receive suggestions based on it.

Is there any way to turn this off? Even with an extension or something?

Hello!

I would like to develop an application that runs continuously, say, at a panel found in a kiosk. I am considering designing it as a webpage that runs locally through the browser but I would like to prevent the users from interacting with the OS or closing the tab and the browser. Is there a way to lock Firefox in full screen and hide the exit buttons? Alternatively, do you have another recommendation for development that is more appropriate, for instance a native app?

Thank you in advance for your help.
