Sometimes all add-ons / extensions break randomly and are disabled (the icon of the extensions is also broken under "Manage Your Extensions").

The extensions are visible under "about:addons", but the slider is turned off and the icon in front of each extension is broken / empty.

It seems that deleting these 2 files- compatibility.ini and extensions.json inside the firefox profile folder, usually fixes the issue. Only these 2 files though, don't delete anything else.

No need to mess around with the ff profiles or anything else, just deleting those 2 files and restarting the firefox usually fixes the issue with the "unregistered" addons.

This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.

I wonder what causes the extensions to "unregister" randomly.

On the page listing passwords, it was possible to sort them by "Alerts".

In settings, there is an option to enable checking the vulnerable passwords: https://support.mozilla.org/en-US/kb/firefox-password-manager-alerts-breached-websites

On my other laptop using Firefox v121, the alerts are properly displayed. But on my second laptop using Firefox v124, the alerts are gone. I can't sort password by "Alerts", the option isn't there. Both laptops share the same Firefox account and have password synchronized between each other.

Obviously, I ticked the "Show alerts about passwords for breached websites" box in the settings but it looks like it does not nothing. I also checked in "about:config" and everything seems good.

Is this feature gone?

When I open firefox it is fine, then ads, buttons, means of surfing then net opens new windows (according to task master) and never closes a window. So once I'm into a game or web site, it's taking over half of my memory (showing like 11 firefox windows open). I can't play any of my games, even minecraft (which is odd). This didn't happen til this last update. Right now I'm stuck at home mending a broken hand, so I kinda need my browser games where I only use my mouse. If there's an easy fix, I'd really like some help in fixing this issue please. Thank you, Lisa Pearson

Recently, I have been unable to hold down backspace to delete multiple characters in certain text boxes in Firefox. Namely, in the EndeavorOS forum post text box, Google Docs, and the google search box. I am not experiencing this issue with any other app, and in chrome, with the same pages, the issue doesn’t occur. The issue also does not occur in the URL box or the forum post text box here. The issue still occurs in troubleshoot mode.

Have just noticed that there are no longer green Norton check marks against web results. Have spent all morning in live chat with Norton. They say it is the way it has been set up. Very disappointed as they check marks were very useful.

Hello,

Why doesn't "open previous windows" work? It can't be checked off in settings. It seems other people have this problem. Are there any fixes? I have a Windows computer with Windows 11. It works on my Android phone, but not on my desktop.

Thank you, Tom

When I open Firefox to my home page any additional tabs that I open keep crashing. The page tells me that it has crashed and there is a restore tab button there but that doesn't work and the crash message just comes back.

How do I perform very basic editor functions like add/remove/move a page in the new Firefox PDF document editor? I am in the Mainstream Firefox 124.0.1 64-bit. Thank You, David

I'm having this exact problem from here , but browser.taskbar.lists.tasks.enabled has always been set to true. Toggling it does nothing in itself in between restarting my machine. I am certain it's not a jump menu thing because this isn't about shortcuts (and besides the point, enabling the jump shortcuts from my OS side of things does not display it either way). I just want the stuff that the user in the above link listed.

Coincidentally, I had this exact problem a short while before, and I think it may have had to do with an update, because I remember Firefox updating at least twice fairly recently and it is in this time I've noticed this issue. The first time around it resolved itself, but this time it has not and I do not know the cause.

Unpinning/pinning the icon on the task bar does not resolve this either. It seems none of the conventional solutions in the past work, so unless I am missing something, something broke.

Hello everyone,

I posted my issue on the french speaking forum a few days ago https://forums.mozfr.org/viewtopic.php?t=153652&sid=96223ded5b326b4da4114d4c0fb4b740 I think I've had this bug since the last update of Firefox. I have checked on other browsers (Edge and Opera), and I have no problem with them. Its also ok on my mobile phone ... with Firefox !

Thank you for your attention and any help you can provide.

Regards Damien

I would love to remove CNN and MSNBC from appearing on my computer. If I can get them from auto playing that would be nice also. What do I need to do? Danny *Email removed for privacy*

Hi I've no idea which section this should go.. I'm having an issue when a youtube channel im following sets a live. When I get the card on the desktop for the 30 min timer, I'll click it.. sometimes it will open in a new tab (usually the card just disappears), that's another problem.. Anyway.. If I switch to the new tab at the time the live should have started, it shows the counter reset to 30 minutes.. if I F5 the page it will load the live.. Is there a way to auto start the live when the counter hits zero?

Hope that wasn't as clear as mud...

Thanks

I am running Firefox 124.0.1 on Mac OS Sonoma 14.4.1.

I set Firefox as my default browser. However, when I have links that should redirect and open in an external application (Apple News, Facebook Messenger, etc.), Firefox does not redirect to these external applications. I have searched the FAQ and the internet but haven't seen an answer to this. As a result I have switched my default browser back to Edge, which functions as expected.

I am facing an issue with my Firefox.

This most commonly occurs with video playback webapps like YouTube Shorts. Intermittently, but often enough to be incredibly annoying!!) videos will stick while audio plays in the background. This does not always happen, but once it starts there seems to be some sort of cooling off period before things work again.

Reddit video player never works, seeming to silently crash - never showing the play button or video controls overlay.

I have had miscellenious other issue with other website that include forms to fill out and navigate where the elements like "next" or "submit" are completely unresponsive.

• Refreshing the page does not fix it.
• Clearing Firefox's cache and data did not fix it.
• "Refreshing" Firefox did not fix it.

Strangely, the same video/page will always work on a Private browser window. I appreciate that these windows don't have extensions active, but I have activated every extension in private browsing and it still works.

The only extensions I have are:

• Privacy Badger
• uBlock Origin
• Bitwarden

I have no idea what it is about my "normal" browser which is broken, and why things are fine in the private window, but this is immensely frustrating.

I really don't want to have to change to another browser (Chrome... ew...) but I need this fixed if I am to continue.

Last update disabled picture in picture mode -- on top of full scree applications.

Please advise how to correct / adjust. This feature is vital to my work.

Thank you for your time and help.

New computer, new install, when trying to log in to my account to set up sync/migrate, Firefox claims the password is incorrect ... the same password I just used on this (old) computer to log in and ask this question!

I've had issues with this before, when I synced up my phone. Took several attempts to log it in.

Also, tried changing password, but for some reason it won't accept a new one? (That's different issue. Would prefer to log in with current password. at least)

Thanks!

I can hear NO AUDIO on ANY webpage, when in Firefox. I have gone through all the suggestions on this page: [https://support.mozilla.org/en-US/kb/what-to-do-if-firefox-wont-play-any-...] but still have the problem.

Today I have discovered that I am unable to access 2 websites on which I have an account - one is a hotel booking site of which I am a member, the other is a cosmetic company. I have accounts with both and CAN NOT even get to the "members sign in page" what is going on? BTW I have tried to read all the info posted on Mozilla and it doesn't make any sense to me at all as I am NOT... NOT... and IT technician, merely an end user.

I'm having a problem logging into one of my banking sites. I talked to the bank tech support yesterday and did a password reset. There was nothing wrong with my old password. That worked yesterday but today I'm back to the same problem. It won't log me in.

I deleted cookies and cleared cache but still not logging me in. I tried another browser (Edge) and got right in. In Firefox, I use private mode to log into financial accounts but I also tried the regular browser and still won't let me in. This is the only account I have a login problem with. It did work after the password reset if that's a clue but I don't want to have to do that every day just to check my account.

Here is the site:

https://www3.citizensbankonline.com/efs/servlet/efs/login.jsp

I need a fix for this. It's very inconvenient and it is the only account I have a problem logging into with Firefox.

Thanks for the help.

On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4
