Firefox Support Forum

Is there an easy way to downgrade back from the beta channel to stable? The downgrade protection feature seems to be a major blocker of just installing the latest stable version. Noticing high RAM usage on Firefox 100 and crashes which is making it hard to use for a daily web browser.

Since earlier this week my Firefox browser has been turning .jar files from GitLab into .jar.zip files, which prevents them from being used properly until renamed. Attempting to download the same files on Edge or Chrome works correctly, and attempting to download any jar files from other websites (even GitHub) also works correctly. It seems that GitLab is the only website that is affected by this.

Examples of files being affected (they should be downloaded as normal .jar files): 1. https://gitlab.com/Trafalcraft/antiRedstoneClock/uploads/3b3c84814d76810f826c3803eaca1e66/antiRedstoneClock-1.4.1.jar 2. https://gitlab.com/Aristois/ui-installer/-/jobs/2505715157/artifacts/raw/packager/Aristois-Free.jar 3. https://gitlab.com/Aristois/Installer/-/jobs/2495195255/artifacts/raw/packager/free/Installer-2.0.3.jar

I'm using Firefox developer edition (102.0b3), and already tried using private mode, resetting Firefox, and reinstalling. Since I use GitLab as a main source to upload files, many users have also complained the same problem to me, in which all of the users were running Firefox. After they downloaded with a different browser, it worked for them as well.

Some videos on YouTube wil not run - shows just that circling arrow !

I'm running a fully updated Windows 10 - F5 don't cure the problem Restart PV, router or modem don't Reset FireFox work but only just after reset - if I try show the same vidoe again - same problem is back ! I have tried running is safe mode - no help ! I've tried to shut down AddBlocker - no help !

It's NOT all videos and not all videos from the same creator !

The problem started 4-5 days ago and is worsening !

What is there to do ?

Lately in Google Drive I get this error when I select one image or a file: Impossible load details. Retry. I have Firefox 108 version, on Edge and Chrome all is OK. Also the troubleshoot mode doesn't resolve the problem.

Whenever I try to open Firefox, it takes about 25 seconds to boot. This behavior can be observed both with all the extensions running and in safe mode. The link to the profiles are shared below.

With extensions: https://share.firefox.dev/3riMPQZ In safe mode: https://share.firefox.dev/3OadE31

I have been noticing this for a few months now. Firefox works just fine after wasting ~25 seconds initially. I have also reinstalled Firefox multiple times. Right after the installation, the boot-up can be very fast (less than 1 second). However, after using Firefox for a few hours, the problem comes back.

I am not well-versed in reading Firefox profiler reports. So, please help me figure out what's actually happening in those ~25 seconds.

A few days ago I was downloading a ZIP file and was warned that "This file contains a virus or malware". Fine, thank you for telling me but now how do I seeing the same warning every time I start Firefox? The file in question does not exist on my computer so far as I can tell and I did a thorough search through 3.5tB of storage on the machine to make sure. How do I stop this warning?

Win10 with what was Firefox 89. I had already disabled the Proton UI on this installation, because it is horrible. Today Firefox decided to update to version 91. All of the Proton UI junk is back. I tried disabling it again, but nothing worked. Doing a web search, it appears that Mozilla has disabled the ability to turn off Proton.

I then set about to rollback the installation back to version 89. I found a Mozilla link on this, went to their ftp server and downloaded the installation files for the last version of 89. The installation went normally, but when I opened Firefox afterwards, a little box popped up saying something to the effect of "To keep your History and Bookmarks from possibly being corrupted, Firefox must create new user profile." I exited out of this and Firefox didn't start. I attempted to restart Firefox again and the same box popped up again. The only way to get past it was to click the accept button.

I did so and Firefox started. This was clearly not version 89. As the UI is junk, it took several minutes to find out that this was now the latest version of 92!!!! I'm absolutely positive that I downloaded the correct file. When I look through the update history, it doesn't even show todays version 89 installation as happening. What a piece of junk.

I then spent 20 minutes figuring out how to revert back to my user profile, not the new one that it had created for me. I then did some research on what had happened. Well it turns out that you can't actually rollback Firefox, despite what Mozilla says. For a while they have added "downgrade protection" which automatically creates the new user profile and stops your old profile from being accessed by it. So unless you want to figure out how to spend a hundred hours reconstructing bookmarks, passwords, settings, etc. it actually isn't possible to rollback Firefox. Doesn't this violate some Microsoft rules about being able to uninstall versions of software from within Windows? If you try to do this with Firefox and go back to a previous version it blows everything up.

Does anyone know how to actually rollback Firefox to a previous version, so that Proton can be disabled?

After I have started the computer and have opened the Firefox Developer Edition, there is no website content visible - everything is transparent. Links are clickable and context menu opens up, but the content is just transparent (screenshot attached).

When I close & repone the firefox, then usually on 5th to 10th attempt everything starts working until next reboot.

Firefox(Default edition v94.0) is working just fine with no problems on same machine.

When I first noticed this, version was 95.0b3. Now I'm on 95.0b12.

OS is Xubuntu 21.10 and hardware is HP ZBook Power G8 - i5-11400H, Nvida Quadro T600.

I've already tried: 1) opening on safe mode, 2) reinstalling using Ubuntu's "umake" commant line tool, 3) reinstalled by downloading it from https://download.mozilla.org/?product=firefox-devedition-latest-ssl&os=linux64&lang=en-US and copying the files, 4) opening computer using both Nvida's and Intel's built-in gpu

but nothing have worked so far - still the issue persists.

Is there anything else I should try?

Thanks!

Good day,

Really happy to see that mozilla is tightening up security. But unfortunately, I can't enroll into Two-Step Authentication everytime I enter code it's not being accepted. I tried multiple android apps of those codes and non of them work for me.

Because of that, I lost access to addons.mozilla.com account, because system doesn't let me in without 2step auth enabled.

Any chance I can use yubikey's intead of those auth apps? or anything else I can do?

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

Recently i found that the memory usage can be very large when watching live-stream,tried many ways to fix but none of them was useful. Then i found the new function of "minimize memory usage" button,it is useful,but not so convenient.Can you please add a new way to use this function? Like: set a number of memory usage(for example 256000KB),when reach this number trigger the "minimize memory usage".Then it will be like "auto minimize memory usage". Or,you can just set an UI button on the toolbar to trigger "minimize memory usage".

Please check my screenshot Pic1:It's the live-stream tab,memory usage 1800+MB Pic2:But it seems not so large in "about:performance"

Hello,

Currently running MacOS Montery but the problem was still occurring on previous versions.

Whenever I use the green top left button to enter full-screen, the app immediately freezes and either crashes or has to be manually force quit. There are no reports in about:crashes and I there has been no success with troubleshooting mode or switching versions of the Firefox application.

Machine Info: MacBook Pro (16-inch, 2019) Processor: 2.6 GHz 6-Core Intel Core i7 Memory: 16 GB 2667 MHz DDR4 Graphics: Intel UHD Graphics 630 1536 MB

Any help towards a solution would be appreciated. Thanks!

Win 10, Developer Edition 103.0b2

This update caused everything to increase in size. Tabs & toolbars are much bigger now. Toolbar and bookmarks toolbar used to fit in the window with no overflow, now both have a lot of items in overflow.

Sites that used to fit at 100% zoom now have to be reduced to 80% or 67% to fit on-screen.

Just wondering what could cause this behavior? Settings?

Note: Browser window is fully maximized and no other program on my Win10 box has this issue.

The default location of the new bookmark is set in about:config，that is browser.bookmarks.defaultLocation. How can i change it with JavaScript in third-party extensions？

If I copy and paste any two words or more into the search bar on the new tab it goes to google.co.uk as that is set but only searches for the phrase minus the first word. If I paste it into the address bar everything is ok. If I do the same with a one word term the search bar does nothing having "lost" that word and the address bar works fine.

I noticed the toolbars had changed positions and thought I'd use the customize page to see if I could reorganize them. Somehow I ended up with the usual three toolbars, but bookmarks are on the top (tabs) toolbar, not the bottom (bookmarks) toolbar, which is empty. This is Ubuntu 21, firefox 95.0b2.

Top: Starting on the far left are the Ubuntu window controls, my bookmarks. and tabs. Middle: The customized URL/search bar. Bottom: The bookmarks toolbar, which is empty. I know this is so because CTRL-SHIFT-B hides and shows it.

I can drag bookmarks on the top(tabs) toolbar around, reorganize them, and and delete bookmarks and folders, but always only on the top (tabs) toolbar. I cannot drag any of them to the bottom (empty bookmarks) toolbar.
