Firefox Community Forum

Using Firefox browser 126.0.1 via Steam Deck desktop running SteamOS 3.6.22; I am unable to download any extensions. I tried to download uBlock Origin and ProtonVPN through addons.mozilla.org, but recieved an error message:

"Installation aborted because the add-onn appears to be corrupt."

I then checked other extensions I found on the front page recommendations, like "Dark Reader" and "Image Search Options" and they gave me the same error.

Could not find anything that helped my situation upon searching for solutions, any help would be appreciated.

I was on YouTube and in the upper right hand corner there was a small splash screen that said Activated with words underneath. It did not show but a couple of seconds so I couldn't read what activated.

I did not change anything. How do I find out what happened? I don't see you offer any logs.

PS I don't know if it was YouTube or not Firefox. But I have never seen it before.

It was rectangle with cream white background, black font, Activated was in large font, under it was smaller font. It covered the hamburger and 3 of the icons in your toolbar. It was half on the viewable window page (YouTube) and half over your icons.

I have FullShot 10 which used to show my extra buttons in the FF toolbar. A few updates ago these buttons have disappeared from FF which is really inconvenient. Those buttons still appear in MSFT Edge. I cannot take a screen capture because taking a screen shot automatically makes the FS10 buttons disappear. FF10 is not add-on to FF, it is just a regular program to easy capture graphical screen information. FS10 has not been updated/altered in any way since its installation

When I open Firefox browser around ten several weeks old tabs are there. It is not set in the setting to open. I did many attempts to get rid of this nuisance and they are still here. I Created new profile, erased all profiles, removed Firefox, and reinstalled with option not to use old setting since new installation found that the fire fox has been installed. And frustration part that Mozilla do not offer (as I know) support to fix this problem. This glitch is hidden somewhere and the program always find it an put it back. I am not sure if what to do as I run out of options, other than turn to another browser after many years using only Firefox with no problems at all. Thanks Ned

Constantly getting the following messages - "Not Responding." "This application is not responding. The program may respond if you wait. Do you want to end this process?" I am on my email or reading an article on my email and it goes blank. Also, I get "Restore session or start new session." The only way I can get to start my computer ( getting the password box ) is if I do Control Alt Delete many times.

Very Frustrating indeed!

Yahoo and facebook are not recognizing my device and always ask for me to sign in with 2FA...Facebook asked if I want this to be a trusted device - I select Yes and next time I log in, password and text code....Yahoo Mail the same...asking for 2FA. I did not ask to be cut on and cannot turn off!!!!

I have profiles on desktop , i had enabled sync in all profiles when the feature was first introduced. the account icon always showed that it is syncing , but in the sync tab , no visited tab list appears of any profile in both the desktop .,, i installed firefox on the android today to check synchronization but its tabs never show in desktop profile and the android tells last synchronization never....neither the desktop tabs appear in android history

I can't get open tabs to sync from my other computer. Bookmarks synced and other info but I don't see anything about tabs from other devices. I've synced both ends, both are logged in and I've selected open tabs in both. Nothing,

I am constantly denied access to my online banking, my bank says, because I use Firefox, and that I wouldn't have this problem if I used Chrome - any possible truth to this? Any fix? thanks

the latest update 136.0.3 is broken. When right-clicking an item, none of the choices work (e.g. right-clicking on any word brings up a menu with 'open in new tab' as a choice, but nothing happens)

My computer displays were dramatically different one morning a couple of days ago, as MS Edge seems to have overtaken control of my system, which included changing the displays on my monitors. I have restored the system to a few days ago when the system was correct, but the restore resulted in the same Edge displays. With considerable effort to overcome Edge, I have also made Firefox my default browser. After resetting and restarting, my One Note pages are still no longer available and my displays have not changed from the Edge-changed ones. Any additional ideas? Please?

I may have inadvertantly blocked Firefox from executing. I run Windows 11 on my desktop, and use SpyBot as my virus defender. Last night SpyBot may have run and prevented Firefox from running. This morning it would not open at all, no matter using a shortcut button or activating the program directly from Menu. I tried re-installing, but a window opens saying, "Hmm. For some reason we could not install Firefox." I tried uninstalling Mozilla but the window opens to initiate the process but in 20 minutes less than 1% of the procedure bar is lit and blinking. Do you have any suggestions?
