Firefox Community Forum

I know it may sound a bit strange, but I would like to know WHY an extension is not allowed in a private window, so I might understand the reason why I'm not able to diagnose an issue I'm having with fucking amazon who has their cart all over the place for a misconfiguration in firefox that either I did or an extension is causing, however I'm unable to figure out which because I can't enable extensions in private windows, where the issue does not happen, so I'm not able to reproduce and isolate the problem. Specifically, this article: https://support.mozilla.org/en-US/kb/extensions-private-browsing Plus, I was kinda expecting I could run STG in private too, since it offer such nice and rich grouping and memory management features vanilla FF does not (PS: please take inspiration and bake it inside!!) Thanks in advance.

I'm using Firefox 141.0 on OpenSuse Tumbleweed with KDE and Wayland. I'm using Firefox with two profiles: work and personal - which is (usually) awesome, until suddenly it's not.

Then, one or both profiles seem to become corrupted, and closing firefox, opening it, choosing either profile just hangs forever. My old tabs show up, but clicking on any tab, for any site, just hangs forever, and no page is ever loaded. Sometimes restarting helps, but sometimes not. Sometimes restarting 2 or 3 times and then suddenly it will work. But normally, I have to just delete all my profiles, and re-create them. Fortunately everything is synced with Firefox sync. Then everything will work wonderfully for a bit - although I have to re-login to everything.  :-(

Any ideas? This is a huge pain and productivity killer. I really love firefox, but this sucks.

I have a new Mozilla (FireFox) account and keep getting emails that say I need to confirm it. They include a button to do so but I'm not clicking it unless I get better information from you. Please help. The email swears my account will be deleted if I don't confirm it. What do I do?

Using version 88.0 and browser - both outdated and not supported. How can I update to newest version and browser? I am 80 yrs old and not computer literate. Please keep it simple. No human help is available - I am alone.

Firefox 129.0.2 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Running on kubuntu Linux 24.04, kernel version 6.8.0-41-generic (64-bit) KDE Plasma Version 5.27.11 Qt Version 5.15.13

I've posted a description of my problem on the kubuntu forums: https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/681835-firefox-eating-up-a-lot-of-cpu

Here is a synopsis of my posts on that thread to distill the most noteworthy symptoms:

I have snap Firefox installed.

$ snap list Name Version Rev Tracking Publisher Notes bare 1.0 5 latest/stable canonical✓ base core22 20240731 1564 latest/stable canonical✓ base firefox 129.0.2-1 4793 latest/stable mozilla✓ - firmware-updater 0+git.5007558 127 latest/stable/… canonical✓ - gnome-42-2204 0+git.510a601 176 latest/stable/… canonical✓ - gtk-common-themes 0.1-81-g442e511 1535 latest/stable/… canonical✓ - snapd 2.63 21759 latest/stable canonical✓ snapd thunderbird 128.1.0esr-1 507 latest/stable/… canonical✓ - $

If I start firefox from the shell command line, it runs fine. It runs the shell script in /usr/bin/firefox, which ultimately executes /snap/bin/firefox. Clearly that shell script is doing some configuration that I don't understand.

If I hit Alt-space I see the menu in the referenced screen grab (see attached).

If I select the first entry, to run firefox from the command line, it has the same effect as starting /usr/bin/firefox from a bash shell; it works fine. However, if I select the third entry, firefox does not play any video; I've mostly tested with YouTube videos that have actual video and audio.

I'm not sure what gets executed when I select the third option from the Alt-space menu. It appears from doing a "ps -ef" that it's the same /snap/firefox/... executable. But I'm wondering why is this entry in the Alt-space menu and how does it get initialized or 'configured' to run.

Additionally, if I do start firefox from the entry with the firefox browser icon, and it fails to play video, I must then uninstall firefox using snap and then reinstall in order to get video playback to work. That is, after a failed start, simply exiting firefox and restarting it from the shell command line will not work; firefox will not play video correctly at all.

I also noticed that on my PC desktop, "snap list" lists firefox as "firefox 129.0.2-1 4793 latest/stable mozilla✓ -"

But on my old Lenova laptop running the same kubuntu version, "snap list" lists firefox as "firefox 129.0.2-1 4757 latest/stable mozilla✓ -"

I'm up to date on both systems via "sudo apt update"' and "sudo apt upgrade"

Even more frustrating, today, for the first time, despite starting firefox from the command line, video still didn't play. I had to uninstall firefox and reinstall it.

I need to connect to my employers Citrix portal tot start a Citrix session for my daily job. The problem is that when try to login using my credentials nothing happens except for the loading icon of Firefox that keeps "spinning" (see image).

When I do the same in another browser, like Chromium for example, everything works fine.

I already tried the following steps:

- Installing an older version of the Citrix Workspace app - Reinstalling Firefox - Disabling the blocking extensions

I am using the following versions of components:

OS: Linux Mint Vanessa 21 Citrix Workspace app: 24.5.0.76 Firefox: 129.0

Other colleagues report the same issues when using Firefox whether in Windows of Linux.

Any help would be much appreciated?

Hello,

I just installed a new version of Linux Mint (Zara) and all is right with Firefox, except the screenshot who doesn't work. The buttons "Capture the visible area" and "Capture the entire page" don't work. The additional tool in the toolbar doesn't work. What can i do, please? Thanks for your answer. Pierre

I am using Ubuntu 22.04. Firefox version is 143.0. IIRC firefox recently updated. I have the setting "Open previous windows and tabs" checked. Until very recently it has always worked but now when Firefox is closed all tabs are lost and don't appear when reopening Firefox. How to fix???

Tried to update Firefox. Got the message: your updates are being managed by your organization. I'm a home user. No organization. What is the problem? Thank you in advance.

I've been using Firefox on Linux since it was Nautilus. Currently running EasyOS Linux Daedalus and Excalibur on different Lenovo ThinkCentre Tiny Core i3-8100t boxes and different drives: A good Samsung SSD and two good flashdrives. 32G new RAM installed on each box. I've been using these boxes for over a year. For the last month or so, ever since updating to v. 146 my tabs have been crashing like crazy! I don't normally have more than 10 tabs open at once. But now, as soon as I open a 5th tab it crashes.

I'm running Top to watch CPU and RAM usage. I see nothing unusual. I've rebooted. Disabled all add-ons and run in Troubleshoot mode. Tabs still crash. My only add-ons are uBlock Origin, Temporary Containers and Dark Mode. It happens whether I have hardware acceleration turned on or off. I don't know what else to try. Here are my most recent crash reports. I hope you can figure out the problem. Thank you so much!

I have an idea for improvement of the mozilla browser, but I don't want to send it online here. So can you please give an email address and I will send it there instead(?).

So I had logged into this Firefox account, but while I was, I forgot my password. I needed to enter the correct code from the email, but I lost the recovery key; I needed to enter in the 2FA code from my phone, then I could now change the password. When I logged in, boom, bookmarks gone. Passwords gone, and browsing history gone. I was waiting for it all to sync, but it had probably synced the deletion of everything possibly. I have no idea what happened, but I do not believe my account was compromised, because I did not get any emails about any new logins. If it is encrypted, how can I decrypt it so I can get my stuff back? Thanks.

I have [[created a backup file|https://support.mozilla.org/en-US/kb/firefox-backup#w_protect-your-sensitive-data-with-a-password]] today with the latest available Firefox and switched to a new OS. Sadly, the backup file somehow seems to have gotten damaged, even if Firefox still recognizes when I'm inputting the wrong password. On Ubuntu, where I originally created the backup and where I tested it again after things weren't working out, Firefox tells me that there is an issue with the file and that I should try a different one (which I don't have). On CachyOS, which I'm currently testing out, restoring the backup never finishes and Firefox doesn't exit cleanly. In hindsight I obviously should 1) have tested the backup immediately, 2) not have wiped my laptop prematurely, and 3) have backed up the folders manually, but I haven't. Now the question: is there some way to extract the account details from the .html file? I don't care much about the rest, but restoring the accounts in some other fashion is gonna be a lot of work.

I often hit ^T (control-T) in firefox without meaning to, because I use that chord in other applications a lot. In firefox it opens a new tab, which is almost never what I want. I'd like to suppress that keyboard shortcut. I tried doing it using vimium (unmap <c-t>) but that has no effect.

Thank you, Silvio

Hi there! The New Tab page looks great with white text, but Firefox 140.0.4 thinks my wallpaper is white, so text should be dark. I can change the body class to "activity-stream darkWallpaper" using the inspector and it works fine, but how make this change permanently?

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?
