Firefox supportforum

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This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.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

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.

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

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

Hello, 1. How do I bring history back -since mid March - after a windows system reset and laptop clean up recently? I signed on but I cannot find the prior history nor tabs closed. I use Windows 10. 2. Why when I open a new tab, the 'profile or account' icon does not show my picture, so as to indicate that I am signed on? Each time a new tab is opened, Mozzilla does not recognize me!! 3. When I click on the account icon on the second row, instead of taking me to my account, it takes me to settings, Synch. 4. I have selected the dark mode - from customisation - but the first two rows are in light blue-gray color same as the task bar of Windows 10. 5. I tied to use the take a screen shot function to send you a screen shot of the page that appears in dark except the top rows, but when I click the screen shot icon - that I have placed in the second top row - it does not activate-work. 6. From the Menu some info shows in Greek although my selected language is English. Is it possibly due to my location, under the profile, being Greece? should I change it? I am sure I ll come across more issues, as it feels as I am driving a new car since the change and all is annoying Thanks

When using the CPU, the browser runs at 144 fps, but if I switch to the GPU, it becomes 60 fps. I tried switching GPUs for firefox in the nvidia control panel and Windows graphics settings - nothing helped. Are there any solutions?

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.

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

I've installed firefox and weirdly when I use youtube or just browsing the CPU is 250 and it's draining my new mac really quickly. This did not happen before on my previous mac. Seeking some help and answers, went to Apple genius bar and they've stated is the firefox application that is causing the fast drain of power.

I Have used Firefox as my main browser for a long time. I've also played the games on pch.com (Publishers Clearing House) for years. About ten days ago, I started having problems connecting. The error messages have changed a little each time, but still no access. I've also tried Chrome and Edge, and still no access. Today, I tried to access on my phone and got a 'site is not secure' message. Any idea what's causing this or what the problem may be? Have you heard about changes to the pch.com website? I can access the site if I turn off my ISP connection and use a data connection. My ISP is Optimum. Looking for any guidance. Thanks.

Just tried to log into DISH Anywhere and received the following error message: "Your browser is not currently supported for streaming Live TV and DVR content with DISH Anywhere. Please use a Chrome or Safari browser to access this content." Is this something that will be fixed? Pushing me towards Chrome . . .

Firefox doesn't work with power management. It essentially turns the screen off and then sends the laptop to sleep when watching videos (in full screen). I have tried to disable hardware acceleration, but it didn't fix my problem. I am on 124.0.1 version - flatpack version on fedora, as the actual fedora version from "discover" app center cannot play videos at all. I am running on fedora 39, kde plasma, wayland.

I'm using the current version of Firefox 124.0.1 (64-bit). I recently noticed that when I print -- there's no webpage title or URL address with date on the bottom even when I have checked and selected print headers/footers before printing. Is this a bug? Can you please help me? Thank you.

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.

Since I upgraded from Kaspersky Internet Security to Kaspersky Plus, my Protected Browser version of Firefox has lost track of my current Protected bookmarks and stored passwords - but the bookmarks and passwords in the standard (i.e. not Protected Browser) Firefox remain the current set. Unfortunately this is a different set, so I no longer have access to the Protected passwords etc. Although Firefox has just updated to 124.0.1 the About display in Protected Browser insists "Firefox is being updated by another instance". Kaspersky have studied the GetSystemInfo report and cannot find anything amiss, so is Firefox causing the problem? e.g. where in Firefox did Kaspersky manage to find a three-years-out-of-date set of bookmarks and passwords?

Running Firefox 124.0.1 (64bit) on my Windows 10 Version 10.0.19045 Build 19045. Every time I open Firefox, it closes within a couple of seconds and then reopens by itself and keeps working. How can I fix this glitch?
