Firefox Community Forum

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

I've been using kelly blue book to research new cars. Yesterday it would load the vehicle information, but when I click on the blue box "see pricing" it just reloads this page. Has worked fine for the past week or more, but yesterday started doing this?

When using shift+tab or ctrl+shift+tab to cycle between tabs in a window, firefox will occasional skip across one or multiple tabs. This will also happen when clicking tabs directly with the mouse. The tab that should be selected shows briefly before the browser automatically switches to one of the adjacent tabs. I do not have the setting "Ctrl+Tab cycles through tabs in recently used order" enabled. This doesn't happen for any specific tabs or windows consistently, and it doesn't specifically happen to unloaded tabs.

Title. 156.0 had NVIDIA Video Super Resolution working just fine. 156.0.1 has broken it on my setup. Nothing I have done has brought it back - toggling settings, clearing caches, forcing it on in about:config, etc. The plugin seems to be broken.

Was working just fine for over a year prior.

Latest Stable Firefox 156.0.1 RTX 5080 Driver 596.49 (May '26)

Does not show as working in the Control Panel, and is clearly not working on any video site. YouTube, the BBC, and Twitch were the ones most tested.

Please consider a fix. Thank you.

I have been having random crashes Firefox Snap on Kubuntu 24.04 (and now 26.04). Sometimes Firefox will run stably for over an hour, sometimes it will crash in less then a minute from (re-)launch. I have tried the usual troubleshooting steps of 'run in troubleshoot mode', 'refresh', disable plugins, but the crashing seems to happen even when running in troubleshoot mode. I also have not been able to figure out any kind of event or user-action that triggers the crash; it might happen while browsing, it might happen while I am not even at my computer. At first I thought 'the Devs will handle this', but it has been some 6 months so I think my case is not very common/pressing to the community. I'd like to take a more proactive approach in solving the problem. I am still a novice at software fixing, so I might have skipped or missed a very basic step in the '10 things to try to fix Firefox'.

I am using Windows 10 . I have MS Edge as well as FireFox browsers installed. I just recently installed Thunderbird.

Since I used FireFox and turned FireFox VPN on and then off (after about 15 minutes) I cannot connect to some websites like rockauto.com using FireFox or MS Edge. If I turn FireFox VPN back on I can connect to these sites (rockauto.com is only one example) just fine. But if I exit FireFox and go to use MS Edge -- I cannot access the websites at all, they timeout.

What gives?

Environment: - Firefox 157.0.1 (64-bit) - Windows 11 (build 26100) - IME: Microsoft Pinyin (TSF)

Steps to reproduce: 1. Open any page with a text input (e.g. chat.deepseek.com). 2. Type quickly in Chinese Pinyin, e.g. "zuihou". 3. At some point during composition, the current composition ("zu") is committed as raw pinyin (with the apostrophe separator preserved), and the next key ("i") starts a new composition.

Expected behavior: - The composition should continue normally, and all keys should be consumed by the IME. - No raw pinyin string should ever be committed.

Actual behavior: - Firefox delivers the key event to the web page with keyCode 73 ("i") instead of keyCode 229 (Process), so the IME never receives it. - The IME's internal composition state stays at "zu" while the browser display has already moved on. - When the next key arrives, the IME commits the stale "zu" as raw pinyin and starts a new composition. - This results in the composition being split into two parts, with the first part committed as raw pinyin containing the "'" separator.

Additional context: - The problem occurs only in Firefox. In Edge (Chromium) on the same machine, typing the same sequence for several minutes never reproduces it. - It does not occur with every key; only certain keystrokes are affected, and it seems to require fast typing. - The issue is not caused by keyboard hardware, third-party software (AutoHotkey, yasb, PixPin, Intel drivers, MuMu), or key injection. A low-level keyboard hook log shows no injected events (inj=0 for all 204 keystrokes).

Log excerpt (from a JS composition probe injected into the page): [ime] 04:20:54.740 keydown key=Process isComposing=false keyCode=229 repeat=false [ime] 04:20:54.740 COMPOSITIONSTART data="" [ime] 04:20:54.741 compositionupdate data="z" [ime] 04:20:54.831 keydown key=Process isComposing=true keyCode=229 repeat=false [ime] 04:20:54.833 compositionupdate data="zu" [ime] 04:20:54.928 keydown key=i isComposing=true keyCode=73 repeat=false <-- key 73, not 229 [ime] 04:20:55.324 keydown key=Process isComposing=true keyCode=229 repeat=false [ime] 04:20:55.326 COMPOSITIONEND data="zu" <-- stale composition committed [ime] 04:20:55.327 COMPOSITIONSTART data="" [ime] 04:20:55.327 compositionupdate data="h"

Since the last update, I've been experiencing some issues with Firefox on my MacOS. Visiting website such as beatport.com and spotify.com, for exemple, after click on "play", Firefox does not play the sound or video. The same happened with other websites with webplayers.

The problem is on Firefox version 157.0.x (tested on Macbook Air and Mac Mini, same MacOS version).

I get this message when trying load SingPass QR Code: "Secure Connection Failed. An error occured during a connection to track.file.gov.sg. SSL received a record that exceeded the maximum permissible length."

We often encounter this situation: both at home and at work, I don't want the Firefox password and browsing history on my home computer to be synchronized to the Firefox on my work computer. After all, there are many private passwords and browsing histories involved at home. However, the passwords and browsing histories related to work can be synchronized to my home computer, so that we can continue to view the records from work at home However, I haven't found this function anywhere in Firefox

When uploading photos, Firefox is not Showing the last folder used. Normally, when uploading a photo from a certain folder, the next time you do that, the same folder shows up unless you choose a different one. Now, it keeps going to one specific folder even though I uploaded from a different folder previously.

Example: say I uploaded a photo from my folder "sympathy pics". Then I upload a photo from "my documents". The next upload pop-up box still pops up the "sympathy pics" folder when it should bring up "my documents".

Can someone please help me?
