Firefox Support Forum

I am currently using Ubuntu 24.04. I recently switched from the snap ubuntu package to using the firefox APT package. However, I've noticed this really weird issue. Whenever I download a file, it always seems to have the "file://" link or mime type.

Say for example I download an mp4 video, trying to open it via firefox results in a dialog asking me to "select which application i want to open this file link in"

I have tried refreshing firefox, and tried completely removing it from my operating system (a search of my entirety of / showed no traces of anything relating to firefox), but even after a clean install, the issue persisted.

The only way I found that can fix this issue is by using firefox nightly, or using the firefox flatpak. And I'd prefer to not use either.

I was monitoring the browser console, and upon clicking on the file in the downloads list, It seems that firefox gets this error:

Uncaught (in promise) TypeError: defaultButton is undefined

   _setInitialFocusIfNeeded chrome://global/content/elements/dialog.js:318
   _postLoadInit chrome://global/content/elements/dialog.js:332
   connectedCallback chrome://global/content/elements/dialog.js:149

dialog.js:318:9

This error does not occur on firefox nightly.

I believe I have troubleshooted this as much as possible on my end, and I'm unsure of what to do about this. Could I please get a bit of help?

Versions: Firefox: 127.0 (64-bit) Linux: Ubuntu 22.04.4 LTS

Description: After some time, and (under unknown conditions), the input delay will shoot way up. Like 20-30 seconds.

Strangely enough, this only applies to keyboard inputs. I can change my tab with my mouse, I can click on things, no issues there. But any keyboard interaction is hugely delayed.

This does not fix itself until I close my browser and restart it. Closing the browser is always broken here too, if I close the browser with the [X] exit button, I then need to kill the process because it just hangs. It blanks out the contents of each tab like it's preparing to close them, but it just doesn't ever complete the task without a manual kill.

CPU usage and memory usage are relatively low; significantly below my system's limits.

I've already tried this suggested fix, to no avail.

The frequency of this is only about once a week at most, usually once a month, so it's not a huge issue, but I'm just worried about this occurring during a critical meeting or something later. Having this impending restart needed is kind of worrying for critical usage times.

this site sucks by the way keeps eating what i type

Firefox version 127.0 Ubuntu 22.04.4

bookmarks toolbar under address bar broken setting set correctly for it to be there and there is a blank space for it to be there but none of my bookmarks that are in that folder show up changing the settings make the blank bar disappear and come back see screenshot.

Firefox home page is missing even though it is set to display just get blank screen on both new tabs and at start up of browser even though it is set to show Firefox start screen.

now every time i start Firefox it demands my master password for my passwords? just hitting cancel makes it go away though.

right click copy only works like 1/4 the time allot of the time the even though the text is highlighted copy is greyed out but using control+c usually works. that one has been happening a wile though.

A while back the behavior of the ctrl+shift+t shortcut changed from reopening tab in the current window to reopening tab in the current window or reopening last closed window which for me and a lot of other people too made it worse. There's been a thread https://support.mozilla.org/en-US/questions/1421356 but it's been archived without a real solution. Is there now a way like a about:config toggle to bring back the old functionality? I really miss the old behavior.

Hello

I am using firefox 126.0.1 (64-bit) version of firefox on a linux system (kernel 6.6). Firefox is closing the main window abruptly (or crashing).

Wanted to get information on the crash, but when I navigated to the about:crashes page, it return a page with title "invalid URL" and the page says "Hmm. That address doesn’t look right."

Is there a way to get to the crash data/information?

Kind Regards Riza

Hi,

Is it possible to save/export (and then restoring) the home screen icons/shortcuts without using Firefox sync?

I want to save its state on my disk so I can restore it later, after formatting, for example. I don't really use any sync features and I actually don't want to sign up for yet another online service if I can help it.

Thanks a lot!

The vast majority of the time, when I open a new tab, I want to go to a page I already visited. Unfortunately, I consistently have to press down arrow to get to what I'm looking for.

I already disabled any kind of search suggestion (settings screenshot attached), added the separate search field, but nothing I tried removed the "Search with DuckDuckGo" being the first suggestion. I pressed the down arrow so many times in my life because of this, I'm at a loss.

Am I missing something? Is there any way to get the history suggestions to be before ANY web search.

Hi! I'm using Firefox 126.0 on Fedora 39.

Pages from Amazon.co.uk load very slowly, incompletely, or not at all. All other Web sites are fine.

I had a couple of certificate-related errors saying that the identity of the site couldn't be verified, but I can't reproduce the problem, so I can't quote the exact wording, I'm afraid.

The same Amazon pages load properly in Chrome on the same machine, and they load properly in Firefox in a VM on the same machine. That tells me network connectivity must be fine.

I've tried disabling all extensions, reverting to the default theme, running in Troubleshoot Mode, clearing cookies and site data, clearing the startup cache, disabling hardware acceleration, and creating a new profile. The new profile helps slightly, in that it loads more of the page before getting stuck. Nothing else helps at all.

I'd prefer not to refresh Firefox if I can avoid it, because I don't want to lose all my plugins and settings. This installation is five years old. Besides, a new profile didn't fix the problem.

What's the next thing to try? I'd really appreciate any ideas.

I often run into issues with PDFs in Firefox Linux. They either appear totally blank (typically after suspend/restore), or they appear with the desktop background showing through (as in the attached screenshot).

Hard refreshing the page doesn't change anything, opening a new tab and opening the PDF again doesn't change anything, opening a new window and loading the PDF doesn't change anything.

The screenshot is with this PDF: https://www.sgsw.ch/home/strom/_jcr_content/Par/sgsw_accordion_list_1838160259/AccordionListPar/sgsw_accordion_12353/AccordionPar/sgsw_downloadlist/DownloadListPar/sgsw_download_1049323524.ocFile/2023-08-31%20Mitteilung%20Elcom%20Erh%C3%B6hung%20Elektrizit%C3%A4tspreise%20f%C3%BCr%20das%20Jahr%202024.pdf

It renders correctly in Chromium.

Firefox 126.0 using the recommended performance settings on Mint 21.3, nvidia quadro p620 using the official nvidia drivers v535.171.04-0ubuntu0.22.04.1

I frequently stumble upon websites with incredibly annoying looping images, with no option or method to disable the image changes. Reading information on websites with constantly changing images is difficult due the distraction.

It would be greatly appreciated if an option could be created to disable the continual image looping - perhaps an addition to the FF settings whereby an On/Off toggle could en/disable a context menu option to Pause / Disable image looping when the user right-clicks on an image. ... or, the browser itself automatically recognises image looping and the toggle simply allows FF to en/disable the looping.

Thanks.

My web site My web site allows user to login with .ejs Sign-up/Sign-in pages then delivers a React page. This works in Chrome and Safari. Https/SSL are provided by my host A2Hosting.

Firefox warns "Cookie “connect.sid” does not have a proper “SameSite” attribute value" when the cookie is set and then blocks the react page after login. If I enter the route that leads to the react page directly I can login and don't get the warning. In both cases the Storage tab in Dev tools shows the same settings for the cookie.

I made sure to remove any cookies for my site before testing the second scenario. I have tested this on Windows, Linux and Android versions of Firefox with the same results.

Here is my Express-Session instantiation ``` app.use(expressSession({

 store: new pgSession({
   pool: pool,
   tableName: 'session'
   // Insert connect-pg-simple options here
 }),
 secret: process.env.SECRET,
 resave: false,
 saveUninitialized: false,

cookie: {

   httpOnly: true,
   Secure: true,
   SameSite: "None",
   path: ['/'],
   maxAge: 60 * 60 * 1000 * 5
 }
 // Insert connect-pg-simple options here

})) ``` I've tried changing the path to include the react app route, I've added it to Cors white list and I converted it to open with an .ejs file instead of .html with no results.

Thanks for your support and for a great browser

Hi,

I use ClassicPress (fork of WordPress) and I have a problem when requesting a password reset link for it.

When opening the email received to reset password in the firefox dev edition browser and click the reset link I receive an error stating that the link is invalid.

I discovered by trial and error that copying the same link and pasting it manually in a new tab of the same firefox dev edition browser solves the issue because then the link is recognised as valid.

This happened after the update I received last week.

I am a linux mint user if that helps in tracking down the issue.

A firefox support article told me to reinstall firefox from snap on ubuntu, without mentioning anything about the profile, settings, and bookmarks. Now everything is gone.

Is there any way to recover my local profile?

I don't think it was synced properly with my other devices

The lag is very problematic to me, because I do most of my work using the browser. When the keyboard starts lagging I can only enter text using copy/paste with mouse (which works fine). The only way to solve it is to restart Firefox (which can result in lost work).

The lag, when it starts, is 10 seconds or more for each keystroke. It occurs about once every few days.

I'm using Ubuntu 24.04 and just reinstalled for unrelated reasons. I'm trying to copy my Firefox profile over from my backup to the new installation.

I used the Ubuntu Snap store to install Firefox and put my old profile in -- this is the one that I was using on my previous Ubuntu 24.04 installation just a couple days ago -- and everything seems fine, but I do see this error message:

[ERROR error_support::handling] suggest-unexpected: Error opening database: Incompatible database version: 18

It gets printed when I type things in the search bar, so it seems related to some sqlite database related to history and autocompletion.

Is there a way to fix this? I'm fine with just deleting it, so long as the other parts of the profile remain.

(This is a strange error, since after all I was using the exact same setup -- Firefox on Ubuntu 24.04, installed via snap -- just a couple days ago, and it was, as far as I know, up-to-date.)

Hi, in my settings Firefox is set to "remember history", but there are no options for how long and when i look into my history, it doesn't go back further than a year. I found a few answers to this on some forums talking about the places.history.expiration.max_pages setting and others about the places.history.expiration.transient_current_max_pages setting but those don't exist in my Firefox and the threads are more than a decade old. I currently have version 126.0.1 64bit on Linux. How can i keep my history forever?

I want to enable cookies for outlook only,the rest I don't 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?
