Firefox 社群討論區

Hi there, im using a grandfathered firefox due to my old OS (10.10.5) Tonight ( 3/15/25 ) all my extensions (duckduckgo, adblocker plus, badger, etc ) were disabled. how can i enable them again? thank you for your time

I have installed OneTab on a Windows 10 platform. Works very well to save memory. Want to add additional tabs to an existing OneTab. Cant find any instructions let alone whether its possible. Have tried contacting OneTab a number of times and no response. Anyone from Firefox know anything about this add-on. Thank you.

Hi, We are using Horizon VDI terminal server. Firefox is installed on these servers. Some users get Firefox is already running but is not responding error. Ending Firefox via task manager does not work. I log off the user and have them log in again, but it does not work.

When I check, I see that the user's profile file cannot be created on any terminal server.

Is there a solution to this problem?

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 I know it's well out-of-date.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.

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

One specific cache entry always contains a trojan virus everytime I run an anti virus check. I can't say where this cache comes from as it appears even if I don't open a single new website. I delete it but it appears everytime I use the Browser again, even multiple times during one session. It is always the same entry code. Is there a way to block a specific cache entry or at least to discern where it originates?

i was browsing youtube and suddenly got an ad, which is how i noticed my add-ons were gone. all of them, not just the ad blocker. and they had still been there like a couple of minutes ago. when i go to download any extension, i've tried a lot of them, it just says "installation aborted because the add-on appears to be corrupt" but it doesn't say what i can do about that. please help!

Last night, firefox just disabled all my addons and all attempts to reinstall any failed with a red warning that everysingle one I had or new to add failed. I tried a few suggestions I found online like refreshing, clearing cash, restarting, but nothing worked.

I have a vwersion 88 (and some change) running on a windows 7 computer.

Any wisdom is highly appreciated.

If I won't be able to fix this, I'll just move on to a different browser after using it everywhere for so many years and it will be sad

Please assist or advise why Firefox seems to be slowing down my system by memory usage. I have a handful (6) of tabs open on 1 browser session and my system started slowing down so I checked my task manager and it shows that I have more than a dozen of Firefox instances open chewing up almost 90% of my memory.

Please assist or advise me on how to tweak my browser to perform better, and not to show ghost instances

Hello, when I am on Firefox I am unable to play audio from websites such as Reddit,Twitter and other sites but I am able to do so in youtube. This does not happen to me in other browsers such as brave/edge. Things I have tried are refreshing firefox, turning off extensions, installing windows media pack, trying a different sound device, adjusting sound mixer, allowing autoplay, update drivers. This started happening after I did a clean install of windows. Any help would be appreciated.

I'm receiving this when I log on to Huffington Post. Never had this happen before. What's going on?
