I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

Dell desktop running Mint Mate 22. Bookmarks missing about 50% of bootups. Saved bookmarks to both HTML and JSON during an occasion they did appear, when they next were missing attempted to restore them via Library pop-up (Manage bookmarks). I could not determine a path to direct the system to either locally saved file. In Library, selected Restore, which then asks me to choose file, but none of the data fields accepted or acted upon input. re-installed Firefox but same result. Then clicked on the saved HTML file, multiple screens flashed on the display, with multiple items in the tray. The final result was the bookmarks were all displayed as expected, but since the problem has been inconsistent, unknown whether they will display on future bootups.

Wish to have guidance on using the Library pop-up to restore saved bookmarks when they are missing. Perhaps some knowledgeable user could post a step-by-step through the restore process.

I am unable to sign in to my yahoo mail account. It gives me a fault that "something went wrong, please try another device". I can use brave as my browser and sign in with no problem but not with firefox. Any idea why?

Firefox version 152.0 : Firefox is continuously refreshing the page on a particular Website, in both Windows11 and Linux versions, making the site unusable ( unable to click anything ). The website loaded ok previously using Firefox and still loads ok using Chrome. Disabling extensions doesn't help, neither does deleting the cache and cookies. What changed and why? Is there anything else to try?

Firefox recently had an update, and now when I am uploading files, I can't double click to upload selected files. I have to first select the file, and then click the open button.

Before the latest Firefox update, I could simply double click on files to upload. This workflow was much faster.

If I go to about:config, and search for: widget.use-xdg-desktop-portal.file-picker, I can change the value from 0 to 2, and then I can upload files by double clicking. However, then Firefox forgets my last upload location, and always opens in the home folder.

If I set it back to 0, it remembers my last upload location, but I can't double click to open files.

My current Firefox version is 152.0.1. Any help would be appreciated. Thanks.

Using the Firefox 151.0 Mozilla Firefox for Fedora. Updated as of 23 May 2026, I use just a generic FireFox. I don't customize it, I just use it as it comes from the Fedora distribution.

I cannot save images (right click menu "Save Image As"). Nothing happens when that is selected. This worked a couple weeks ago.

Downloads are supposed to go to ~/Downloads. Checking the setting for this, Go to the three-line menu > Settings > General > Files and Applications, under Downloads, the "Save files to" value is set to Downloads, but the Browse button does not work to reset it. Nothing happens when I poke on the button. I can select the text in the box, but I can't change it.

I found the help page for "What to do if you can't download or save files https://support.mozilla.org/en-US/kb/cant-download-or-save-files and went thru every one of the steps there. None of them make any difference.

Strangely enough, there isn't even a "Downloads button" in the top toolbar. If I right click on the top toolbar and select "Customize Toolbar" it shows a downloads icon as already being in the toolbar, but when I click Done, it goes away.

Firefox has been crashing regularly for a full day now. I have one profile with multiple extensions, and a fresh profile that is meant to test firefox without any. With this new, "clean-slate" profile with none of my extensions installed, I still get repeated crashes. It is getting in the way of my ability to work- it happens even in Troubleshoot mode, even though I could not confirm any hardware issues prior to this.

Will I need to delete the extenstion-filled profile entirely before going forward? Is there an update I need to install, or anything else I should do myself? Should I provide a list of my extensions?

Attached is the Report ID of my latest crash- hopefully it will help.

Thank you!

1. This could be under-reported problem. People will have problems reporting this bug

2. Whenever I try to save anything (image, website, Ctrl+S, print website to file, Ctrl+P, screenshots, same problem) my Firefox tries to "Open" something instead. I see dialog window with header SAVE, but the final button is labeled "Open" and after clicking it usually nothing happens. A haven't been able to save anything since this update. Only system-wide screenshots work for me now.

I had to use another installation in order to attach screenshot here. In the problematic 149.0, after clicking "Browse..." and selecting file, nothing happens, and no upload, moreover button won't respond to clicking anymore. Then I force refresh, and this text within this form disappears, but attached image appears.

3. Yesterday I have updated my Firefox to 149.0, using official debian sources, mozilla-deb - 1.0 -

cat /etc/apt/sources.list.d/mozilla.list deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt/ mozilla main

4. I have Linux Debian, (old version, Stretch+backports, yes, I am moving things already to new hdd), maybe it's related: 4.9.0-19-amd64 #1 SMP Debian 4.9.320-2 (2022-06-30) x86_64 GNU/Linux )

In order to fill this form I am using separate installation 140.9.0esr (64-bit), you could warn Debian teams not to propagate this error.

5. I have checked Console and Debugger, but they seem website-related. This error happens on every single website. Tried already troubleshooting mode, same problem. Please help us.

My current version of Firefox is 149.0 (64 bit) Mozilla Firefox for Arch Linux Arch Linux - 1.0 I am running this on two computers, a laptop and a desktop, both running Arch Linux, currently at 6.19.10. I use the laptop much more, and recently noticed that I cannot upload or download files with Firefox. No file selection window opens and the request is simply ignored. Nothing appears in my Downloads folder. Meanwhile, I also noticed that this function works just fine on the desktop computer. I don't remember making any settings changes. I do have popups generally disabled but can enable them for certain sites. In any case, I have tried enabling popups and redirects completely with no change. I figure there must be something different about the settings on these two Firefox installations, but what? What can you tell me? Or ask me? Thanks.

Hello everyone,

I would like to ask for clarification regarding the distribution of Firefox through third-party packaging methods.

As I understand it, Mozilla's trademarks and branding are protected, and in some cases official permission may be required to distribute Firefox under the Firefox name and branding.

Within the Ubuntu Touch community, there is a method called "Crackle" that can repackage existing applications and make them available as installable "Clickable" packages on the platform. One of the applications that has been repackaged in this way is Firefox.

However, this Firefox package is currently not available in the Ubuntu Touch software store because there is concern that distributing it may require explicit permission from Mozilla.

My question is therefore:

Does a project or community need Mozilla's permission to distribute a repackaged version of Firefox through a software store? If so, what would be the correct process for obtaining such permission? Alternatively, if the software is merely being repackaged to provide an installation method on another platform, without modifying Firefox itself, is additional permission still required?

We would appreciate any clarification regarding Mozilla's policies on redistribution, repackaging, and trademark usage in this context.

Thank you for your time and assistance.

They play for a couple of seconds, then the panel they are playing in goes black. They used to work a month or two ago. Videos play fine in YouTube. They also play fine in apps like VideoPlayer and VLC. They play fine in Chromium based browsers Opera, Brave and Vivaldi. My graphics card requires switching acceleration off. I can’t find a switch for that in Firefox.

Problem Videos start playing, then after a few seconds the video panel turns black. Audio may continue. Refreshing does not help.

Environment

   OS: Fedora Linux 43
   Firefox 147.0.1 (also tested Firefox Flatpak)
   Display server: Wayland and X11 (both tested)
   Hardware acceleration: on and off (tested)
   Media Source Extensions: enabled (disabling MSE triggers an “unsupported device” error)

What works

   BBC News videos play correctly in Chromium-based browsers (Brave, Vivaldi)
   Videos play correctly in mpv/VLC
   Other video sites (e.g., YouTube) play correctly in Firefox

What I’ve tried in Firefox

   Disabling hardware acceleration
   Disabling VA-API
   Disabling WebRender
   Disabling RDD sandbox
   Running Firefox under X11
   Using the Firefox Flatpak build

None of these measures help. This suggests the issue is related to Firefox’s interaction with BBC’s player on Linux. Has anyone else seen this, or is there a known workaround?

In my nightly broswer Codeberg opens once when I click to go to a repository the tab keeps loading and does not stop and can't accesss anything then. In Firefox I don't have that problem at all only in Nightly then in Nightly my Facebook emoji's does not show but again in Firefox it does.

Popup GUI elements if pulled up twice in quick succession spike my CPU usage and crash the program

some examples: -menu bar menus -the menu button -context menus (websites with their own context menus do not do this) -preview tooltips

I've tried disabling extensions, turning hardware acceleration off and on and disabling AI to no avail. Disabling the preview tooltips 'worked' but I'd prefer not to disable everything here. Are there any other settings that might help?

Everytime I restart and open firefox and then try to access facebook, sometimes google, n=some news websites and probably other apps, I get a captcha, but it repeats no matter how many times I get it right.

I was advised to do this, but it's still happening: https://www.youtube.com/watch?v=6fX0_wiVKhw

But even that's stopped working.

I cannot access facebook and I need it for work (small org, no IT section to ask), and can't access some new sites.

I've gone to basic security settings, but that doesn't help.

What to do?

• OS: Debian (trixie)
• Firefox version: 149.0b3

Firefox suddenly crashes without any displayed error. Attempt to troubleshoot it in "safe mode" doesn't help (it also suddenly crashes.

• When I had redirected following output: "Exiting due to channel error."
• after restart, I launched "about:crashes", but there were no entries

If I'm not mistaken, between FF146 and FF147 it appears the location of the profile directory has changed. It was:

   /home/<user>/.mozilla/firefox  

and now is

   /home/<user>/.config/mozilla/firefox

Is that correct?
