Firefox Community Forum

Hi,

I have a very old version of Firefox (51.0.1 64-bit) on Windows 7 Pro. I know it's well out-of-date. It's not my "main" browser, but there are some things I use it for because there are (were) some handy old extension on it. For example there's an extension that simply copies any text I highlight, without my having to press CTRL-C. I find the "scrapbook" invaluable for saving info offline.

Yesterday everything was fine. Today ALL the extensions have been disable because "[extension] could not be verified for use in firefox and has been disabled". There is no option to enable them again.

I have backups of the extensions (xpi files), but firefox is telling me that they appear to be corrupted.

Is there any way to either enable the disabled extensions, or force firefox to reinstall then from my backups? I have toggled "xpinstall.signatures.required" to "false".

Thanks for any help.

very frustrated, and pissed at how programmers always screw things up that are working just fine by upgrading crap. Now, I have suddenly had all of my addons quit working, was forced to update my firefox. Nothing changed, and it still shows that I am using version 105, instead of the all-new, better and fancier, singing and dancing crap that is being forced upon me.

I have been using Linkman for over 15 years and have a very large collection of bookmarks. Is there anyway to enable it? I'd hate abandon Firebox as I do need this extension please help.

Thanks

apparently, programmers don't understand how aggravating not having backward compatibility is to the rest of us, so please bear with my extreme aggravation here. IF IT AIN'T BROKE, QUIT FIXING IT.

 firefox disabled my addons, thus forcing me to upgrade, and now I am angry. Tried downloading the new version several times. My os is as updated as it can get. Using the APT link from this site, it just shows garbage. Using the download for linux 64 bit link, it makes me jump through hoops and looks like it is working, but it looks different and none of my bookmarks transferred over. Closing it down and reopening it, I see the old version, thus making it look like I am possibly running both versions separately. Once the *all new singing and dancing special that is supposedly so much better than the old that some ignoramus decided I MUST use it instead of the old and functional one* is closed out, I see no way to reopen it. And neither version will enable or allow me to download singlefile. That is the only program I need from firefox at this time.
 Will somebody please show me, step by step, as if I am 5 years old, a back door that will enable my addons, before I go nuts and start beating programmers to death with reams of algorithms?

Using Firefox, when I enter Puritan.com in the search bar the browser takes me directly to Nestle.com (a foreign website). This does not occur when using the Chrome or Edge browsers.

I've just updated Firefox to 136.0 and found the "return closed tab" key became blank and ineffective. I read the update log but didn't find infomation about this change. The function was useful to me and I hope to get it back.

Videos on Bluesky have never appeared for me, instead they all say "Your browser does not support the video format. Please try a different browser." This seems to happen regardless of the video source.

My automatic address has recently been changed in your system from: [edited private information from public] to: [edited private information from public] Please delete the second and revert to the first. Thank you. Roger

The other day I discovered all my extensions have been disabled. I have an old Mac and am not able to upgrade to a newer version of Firefox. Is Mozilla going to offer a solution for people like me who find their preferred browser to now be frustrating and inefficient? I would love to restore my add-ons. Thank you.

For some weeks I have ad an issue with Firefox using 50%-100% of CPU. Normally it is the Firefox process itself, sometimes it is also "Privileged Cont".

OS is Kubuntu 24.04. Firefox has done this across 2-3 versions.

Things I have tried:

Restarting Firefox No change, I'll even get 100% cpu usage with no tabs open

Refresh Firefox to remove settings and addons No change

Uninstall Snap and try direct Apt package No change

Remove ~/.mozilla to fully remove any residual settings/cache/etc No change

Try with and without hardware acceleration See: https://support.mozilla.org/en-US/questions/1308215 No change!

I would blame my old computer hardware, but Brave runs fine. I am now using Brave, but would dearly like to return to Firefox as I miss containers, and I don't support a chromium dominated web.

I can only see 2 emojis on my Facebook items. I used to see 5 or 6 This is a recent problem I can see them all if I use another browser Why is this, and can you fix it? I like Firefox.

When I do a search on Firefox nothing is being displayed - just a blank screen i.e. no results.

I've typed the exact address of some websites - not all work e.g. www.nsandi.com. Again, a blank screen.

What setting do I have to adjust on my browser or is this a wider problem with Firefox?

Thanks

I have an issue where I will frequently get the error pictured on random sites. This started happening a few years ago at my previous home with my old computer. It got so annoying that I had to switch to Brave browser for a while. I recently moved to a new residence, I have a new computer, and a different ISP and equipment, so I thought I would give Firefox a try again. To my shock, the issue still occurs exactly the same way at the same rate. I would say it is as frequent as 1 in 5 sites that I visit. If I hit the Try Again button 5 or so times, the site will load. The only thing I can think of that is common to the old computer and the new one is my Firefox account. Could there be something in my settings causing this to happen? I remember that I even tried Librewolf before switching to Brave but the issue occurred there as well. Any assistance or tips would be appreciated, I feel like I am going crazy at this point. xD

Hello, recently, my Windows PC always asks for the master password when I open Firefox. The method of removing the master password, then closing Firefox completely and resetting the password the next time I start it doesn't work! Observed in Firefox 136.0.1 in Windows 10 and 11. Also new and surprising is that Windows 11 requires the window pin to be entered before a master password can be set. No security software (except Windows Defender) installed. No new software - except for the regular update of Firefox . The observed behavior is at least very annoying, perhaps frightening( who needs my Windows password?).

Maybe it is a new feature and unwanted "windows security" Wolf Piotrowski I attach a screenshot of "windows security Mozilla" pop up (in a german installation of windows/firefox)

When I open a new tab I get an error message if I do not have the web address. This is the message I get.

ie general search for stained glass patterns

Error Description: Could not process this "GET" request.

HI, there are certian websites that I can't use Firefox with. Its like I cant log in properly. Is a reason? Or do I need to fix my settings? I hate chrome. I don't want to use it, but for some of these sites I have to. Is there something I can do?

Thank you, Michele

When I click on an email in the left-hand list column it now opens the email in an irritating pop-up window. Just started doing this annoying this this past week. I DON'T want it to open the email up again--just want to read it in the right hand display screen. How can I stop this extremenly annoying thing from happening. Never did it before. Don't need it. Extra work. Just want to see the list on left, message on right and NOT pop up into new separate window. Can you tell me how to get rid of this unwanted 'feature?'
