Firefox Support Forum

FIREFOX even in safe mode failing to allow login to Spectrum.net. EDGE and OPERA do allow, problem began approximately 3-14-2021. The login process ends up with a message "We're sorry, something has gone wrong. Please try again." LASTPASS is NOT the cause.

Thanks Fred, but none of the suggestions helped, and most of them did not apply. The site does load, but the verification process acts differently now than it previously did (and still does with the other browsers). There are now several "redirecting to" messages displayed that did not happen prior to this. Also, in FIREFOX I used the username/password reset option, after/during which the login succeeded. NOTE that the problem is a LOGIN problem and not a connection problem. Nothing else in my computer has changed; same security software running as it was before Firefox started this failure. I don't think any updates to any of those happened at the time of failure. There was a major WIN-10 update, and I did experience some problems as a result, and I do not recall if Firefox started to fail at that time. I don't think the update was connected, but not sure. Everything else still works normal (and well) in Firefox.

Firefox won't load. I'm getting a Parsing Error: undefined entity, Line Number 744, Column 15. I have uninstalled Firefox and reinstalled but it still won't work. How do I fix this?

After installing Firefox on Windows 10 it never opened, the process just kept running but no window ever opened. Then I copied all of the files from my backed up profile to the new profile and now Firefox opens a window but it is completely white and it hangs forever.

Running Firefox in safe mode does the same thing.

I'm attaching a screenshot with the white window

Suddenly I am no longer able to launch any internet searches. Using google (normally) or bing I receive one of two messages, "Deceptive site" warning or "Server not found"??????????????????????

Nonostante ho disinstallato e reinstallato e provato in modalità provvisoria il problema persiste. Vi invio ID segnalazione del crash bp-7945bba9-d1e0-478e-b2d0-d74c60210322 Cordiali Saluti.

Recently, I think it was yesterday when I updated FireFox developer to 88.0b2 (64bit) on my OS Windows 10 Pro (x64) 22H2 19042.870.

Firstly I noticed "take screenshot" option dissapeared from "3 dots" on the URL bar. Secondly, the "paste" (right click or CTRL + V) stopped working.

I cannot paste text neither from my Notepad or some Text Editor as usuall to some input field or textarea on some Website.

I can copy text from some input field of an Website, but cannot paste the text inside it from a Windows Explorer or whatever.

What is that wrong with FireFox stable/unstable versions?

I've had problems on "normal" FireFox, now I got them either on "developer". I really like this browser, but more and more it seems I would need to switch to some other just because.

Hello my number 1 browser community. I have a problem with fire fox starting super slow. I use firefox nightly(i love it!) but i tried all the stuff in the solutions area for fixing slow start up but none of them help. I always use only 2 add ons and they are the same add ons i have been using for years. i have had this problem for like almost 2 years and i dont know what to do. i tried re-installing, refreshing, clearing cache, safe mode but nothing fixes it. The 2 add ons i use is ublock origin and https everywhere, please help me guys cause sometimes it takes up to even 4 mins for firefox to start.

I get the SEC_ERROR_UNKNOWN_ISSUER on some websites like google and youtube. I can't go past it and it is super anoying. I tried setting the security.enterprise to true but that makes my browser super slow so that is not an option. How can I get rid of this?

I have been able to access my sbcglobal.net email up until to day.

• Today, I got to https://currently.att.yahoo.com/ as usual.
• I select "sign in"
• I select my account
• The account tries to load until I get this message:

   An error occurred while processing your request.
   Reference #97.4f397c68.1616602006.71f9255 

• I have tried adjusting protections to no avail
• I can sign in using another browser, but NEVER with FireFox.

Any suggestions? Otherwise, I think that I may need to dump FireFox.  :-(

I am receiving too often the message "A Page is Slowing Down Your Browser, What Would You Like To Do?" It becomes annoying. I tried the same site with Edge and it responded faster. What can I do other than switch browsers?

A couple of days ago I tried to login in to my account at dpreview.com, and got a '400 Bad Request Error' that pretty much locked up my Win10 system. No problem logging in to other websites using FF, and I was able to log into the dpreview.com website using Chrome, with no problem. I just updated FF this morning with the latest release, hoping that might fix the problem, but unfortunately, same error message.

On a different computer, also running Win10, I was able to log into that website with no problem, so it looks like it is only on this computer, using FF to log in to that website, that the problem occurs. All other links at that website work fine.

Any thoughts/suggestions?

The issue's been going on since yesterday, the app will freeze up like it's about to crash, but then it'll just pop back up. It does it repeatedly and nothing I've done has fixed it, from restarting my computer to closing the browser. Its only gotten worse and I haven't been able to find any relevant information on how to fix this.

Firefox doesn't show sent messages in Gmail. Neither individual sent messages nor conversations that include sent messages. The message lists display fine, but when I try to open a message / conversation it only shows a blank page. Currently the version of Firefox on this computer is 83.0 (64-bit), although the problem occurs since the most recent versions. It only happens with Gmail. Yahoo! and AIM work fine. Doesn't happen in Chrome or Edge

This has been going for a couple of days.

I have tried starting in safe mode, didn't help.

I have tried disabling JavaScript, didn't help.

Two "main sites" affected, Feedly and Gmail. Feedly had this problem but it disappeared after a while. Now Gmail is having problems. I can move around and read mails but not respond to them.

Other sites affected "seems" to have in common that they are blog-type, perhaps like WordPress or similar.

I have a Windows 10 computer with the same browser setup and there have been no problems there so far.

The version is 86.0.1 (64-bit).

I'm not technically advanced so please be gentle with me.

Firefox has a "list all tabs" button, which looks like a "v" in the tabs bar, next to the plus. It works great but when I maximize the window (not F11 full screen, but Windows OS Maximize Window), this button disappears. Seems like a bug; I can't think why you would want that button to be removed when the window is maximized.

There's a glitch where the little gray box with "Timed Out" appears at the bottom of the browser, but if you hover the cursor over it, it will move the right and if you move to the right and hover it, it will revert.

Hi,

I think I broke the ALT keyup events in some way, probably with my configuration but not sure how.

If I put this code in the console : `document.addEventListener("keyup", e=>console.log('alt: '+e.altKey+' | '+String.fromCharCode(e.which).toLowerCase()));` and the press the keys, I have the following results:

- pressing "I", I get the expected "alt: false | i" - pressing "ALT+I", I get "alt: true | �"

I do not have the problem with other modifier keys like CTRL

I have been having issues for multiple weeks now and I am at a point where I am considering switching to a different browser completely.

My issues are very random and I haven't been able to find a link between the problems. Firefox works fine for some websites, loading them quickly and loading everything on the website, but for other websites it just doesn't. Some websites will only partially load, mainly pictures/thumbnails and comments being the problem, sometimes the problem is fixed when I reload, but it usually persists. Youtube is a website that very clearly shows my problem, I have added 2 screenshots of that. Sometimes Firefox just flat out refuses to load anything in a tab, which is only fixed if I open a new tab and try there, or wait insanely long.

I have tried loading websites in different browser, never running into the same problems there. My internet is also not bad enough to have problems loading. I have tried deleting cookies and cache, turning tracking protection on or off, making a new Firefox profile, starting in safe mode, refreshing firefox and reinstalling firefox, but none have solved the issues.

I hope somebody can help!

Hi all

For a while now I've had a problem in Firefox where images randomly show up with green blocky glitches or yellow lines on them. Also sometimes text does not show correctly. I've attached a couple of examples. The image is from my Facebook feed (but it can happen on any website it seems) and the text is open tabs - the one on the right is this page.

Any suggestions? I've refreshed the Firefox install, and have only one add-on - an ad blocker. I've tried two different ad-blocking add-ons and the problem persists with both.

Thanks
