Firefox Community Forum

I've encountered a very weird behavior: when selecting where to save a file or selecting a file to upload, the browser hangs 100% of the time.

Even when I go to about:memory, click Load, the path selection window appears - regardless of whether I select a file or close the window, the browser hangs and the window stops responding. I tried waiting for several hours - to no avail. Only restarting helps. Same with the upload selection window - regardless of whether I selected a file to upload or closed the selection window, the browser hangs. Before freezing permanently, the mouse cursor stops moving, then lags around a bit before recovering.

I tried cleaning download history, cache, recreated profile, restarted without extensions, in safe mode, disabled antivirus - always the same result.

Please advise me, maybe someone has encountered something like this - I really don't want to start using Chrome. My OS is Windows 11. Thanks in advance.

I have sent several emails and get no reply, how am I suposed to fix check or see my saved passwords if they all look like this...3b4a3f36-7056-4eee-bcb3-2b0838fa07e1

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

I searched Microsoft forum and opened the first link (https://answers.microsoft.com/en-us). On Firefox, Go back one page (back arrow) button was not working on this website.

Hello, When I view some pages with inline video graphics, I see a garbled video frame. I have attached a screen grab from part of one screen. I have no issues with YouTube or other videos. It's just the graphics of some webpages such as looking at an Apple product on their site. I have not had this issue using Chrome under the same conditions. It's like I have a corrupted Codec or something. Does anyone have any suggestions? Thanks.

I added 2FA to my account on 10 October 2021, and recently bought a new phone with a fresh Authenticator app. I have all my backup codes saved already so I thought it wouldn't be any worries.

I was wrong, I've been facing this error for all the 10 different codes: Backup authentication code not found

I only have one Firefox account with 2FA, so I'm 100% confident this is the right account. I have access to my email associated with the locked out Firefox account and I can see the email mentioning that I activated 2FA on 10 October 2021, and there are no emails beyond that regarding my 2FA.

I am a developer who have published Firefox Addons - so I am not able to just create a new account, I need this account specifically.

I have the following info:

• Email
• Password
• Backup codes (that don't work, I can provide screenshot of the codes upon request)
• Gmail Access associated with the Firefox account

Help really appreciated, Tomas

Middle click on ordinary text links works as before. But on some pages a middle click on a button shows a vertical scroll up/down icon as when middle clicking outside the button, instead of opening link in new tab.

The problem begun Friday 29 September after I updated from previous esr-version (think it was 102.-something). I have tested on my old Windows 7 PC, and it worked fine before update, but same problem after updating to 115.

I have verified that about:config browser.tabs.opentabfor.middleclick = true.

One example from a free site: https://sok.riksarkivet.se/scb-fodda-vigda-doda?Forsamling=huddinge&Lan=0&DatumFran=1880&DatumTill=1890&Dokument=F%C3%B6delse The green button with text "Bild" is the problem.

Just fund that the green "Bild"-buttons on other pages on same site works just as before: https://sok.riksarkivet.se/?postid=Arkis+eef4e56e-60a2-4221-9c36-8a7a68280d28&tab=post&flik=1&s=Balder

The option to restore tabs and windows is no longer working for me. I normally have a dozen tabs I work thru every day. Yesterday when I shutdown Firefox, all those tabs were there. Today when I open Firefox it only had to single Firefox default homepage. Checking under History there is no option to restore previous tabs, and the recently closed tabs was empty.

To test, I opened an IMDB page and pinned it. I then went to Wikipedia. This gave me a pinned and unpinned tab. I shutdown Firefox via the "X" to close the window. When I restarted Firefox there was only the default homepage. Neither IMDB nor Wikipedia showed up under recently closed tabs and no option to restore the previous session was available.

I have operated Firefox this way for several years. I don't know why this behavior is no longer being supported.

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.

Firefox tabs start crashing all of a sudden and won't stop crashing, until BSOD happens.

In my case it caused PFN List Corrupt Blue screen error.

How can I identify the real reason for the crash of the tabs, leading to the crash of the system?

Others having resolutions other than 1920 x 1080 are having the same problem. Any help would be appreciated

Trying to use ProctorU with Firefox 104.0.2 on Windows 11 Home, and I am getting the following message : "Monitor Count : You may only use 1 monitor during your exam. Your monitor count could not be found". I searched for possible fixes, and someone mentioned removing fingerprinters, and possibly also remove cookies and tracking content from Firefox enforcement. I removed all 3 and that did not help. I also tried clearing cookies and site data and also cached web content, this did not help. Is there some other setting in Firefox that might be preventing the detection of the monitor count? Any suggestions on how to fix this issue?

Firefox releases email addresses and our data to third parties!

I installed the Arc browser and Arc offered to load my bookmarks from mozilla. Out of curiosity, I let it, and it loaded my bookmarks and folders smoothly. Arc didn't navigate Firefox to the login page, so Firefox released my information without asking me.

What probably happened in the background was that the Arc browser told Firefox which email address it was requesting data from, and Firefox handed over the data to it "on notice". Firefox was not even convinced that the real owner of the email address asked the Arc browser to synchronize the folders.

Is it the famous Firefox reliability?

Had it yesterday, happened this morning after the restart and just NOW, when I entered 6 lousy tabs, and they are NOT in the recently closed list either.. wups, gone, no tabs, setting has a check mark on open previous windows and tabs. Within 24 hours, lost the tabs three times with a non reported crash and Firefox closing itself with no warning.

I honestly do not think I am responsible to keep a backup of my browser history, I expect a browser to do that. I switched from Opera to Firefox not to long ago.. even Opera is a security risk.. at least it doesn't delete your tabs just for fun.

Very simple.. that happens once more and i am OFF this browser....

Firefox is deleting my website exception list whether I have "Delete cookies and site data when Firefox is closed." checked or not. It is the same with the exceptions list for logins.

I've searched for answers. I tried the About:config and changing some settings to false and others to true as suggested (e.g. browser.search.context.loadInBackground), etc., and of course I have the option chosen under settings.

This is a new computer. My old computer would switch to the new tab when I right click it, but this new one won't.

Any latest fixes?

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

I'm trying to log into this page: https://accounts.firefox.com

The sign up or sign in button doesn't work. The first time I click it, it immediately refreshes. I click again and nothing. On the 3rd click, it just spins for 30 seconds then goes back to being blue. This continues every time I attempt to click further.

I can login on this page just fine using Firefox on my android phone. I can also login using the Edge browser. Matter of fact, I had to use Edge so I could post this issue.

This is a completely fresh install of Firefox, on a completely fresh install of Windows.

My Firefox browser automatically updated a few days ago. Since the update, the browser now crashes repeatedly during basic browsing, making Firefox essentially unusable. For instance, retrieving Yahoo mail, reading articles, accessing login pages -- the page will enter some type of refresh/reload cycle and crash the browser.

I opened the browser in troubleshoot mode and the problem did not occur. Following the Mozilla instructions, I disabled extensions and reopened the browser normally, and the crashes continued. I have not taken any additional actions.

This problem began immediately after the latest browser update on 9/13.
