I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

THIS IS MADDENING AND I WANT IT TO STOP. i AM SAY FOR EXAMPLE FACEBOOK AND I AM SCROLLING ORIGINALLY I HAVE THE PAGE SET AT 90 AS I SCROLL IT HAS GONE AS FA DOWN AS 50 WHY WILL IT NOT STAY WHAT IS GOING ON AND WHY IT IT KEEPS DOING THIS I WILL GO TO GOOGLE CHROME AND NOT GO BACK TO FIREFOX THERE IS NO REASON IT SHOULD BE JUMPING LIKE THAT AND DO NOT TELL ME IT IS AD OS BECAUSE I TURNED THEM OFF AND IT STILL DID IT RIGHT NO AS I AM TYPING THIS I STARTED AT 100 AND NOW IT IS 50 AND AS I SCROLL HERE IT CONTINUES TO GO LOWER AS I MOVE THIS PAGE THE NUBER KEEPS DROPPING WHY??

I am experiencing significant performance problems in Mozilla Firefox when using certain AI-powered tools. Below are the specific issues:

   Flux AI & Diagramming AI Performance Warnings

       Issue: When accessing Flux AI or Diagramming AI tools, Firefox displays a warning message stating, "This site is slowing down Firefox."

       Observed Behavior:

           Delayed response times or freezing when interacting with these tools.

           High CPU usage (observed via Task Manager) when the tools are active.

       Expected Behavior: Smooth operation without performance degradation, as seen in other browsers (e.g., Chrome or Edge).

   CMS Sign-Out Failure

       Issue: Unable to sign out of my Content Management System (CMS). The action either freezes or refreshes without logging me out.

       Troubleshooting Attempted: Cleared cache/cookies, disabled extensions, tested in Safe Mode—issue persists.

   ChatGPT Menu Error

       Issue: Clicking the three-dots (⋮) menu in ChatGPT triggers an error instead of displaying options.

       Error Context: Mentions "Flux AI," suggesting a possible conflict or integration failure.

Yesterday, the Firefox quit working. Today my connection was verified by Fios and during the phone call, we tried Google Chrome (Yuck!) and it worked on the internet. I have downloaded the latest Firefox and it still does not work. Is there a problem with Firefox? Should I delete Firefox and reinstall?

Firefox version 137 browser update gives errors in web application when submitting form - ns_error_net_empty_response, and does not load js libraries - NS_binding_aborted

I have to manually change the layout.css.devPixelsPerPx setting evertime I switch from my laptop to an external monitor. What can I do to avoid this every single time?

Since April 5th I have lost spell check in the message pane of the emails I type on outlook.live.com It still works in the subject line, but not the message area.

Windows 10 pro 22H2 updated to end of March, when spell check was still working well. Firefox 137.1 English Canada Language selected (has worked well for years)

I go to outlook.live.com to read and answer my @hotmail.com emails.

When right clicking on a misspelled word in the message area I get only these options, Firefox does not give me the usual options.

I am currently having other problems on that site, clearing outlook.live.com cookies does not clear the problems.

In trying to access (log in)Social Security Administration, I received "Bad Request""your browser sent a request that this server could not understand. Size of a request header exceeds server limit" I was able to log in with Chrome. Can this be corrected by mozzilla?

This is an authentic secure sitethat each patient at Duke Medical Center has access to view their medical information and make appointments. I have used this site many times. Please verify that it is a secure site. I need access.

Dear Mozilla Support Team,

I am writing to report an issue I have consistently encountered while using the Firefox browser. Whenever I log into my Mozilla account, the custom theme I have selected for Firefox is reset to the default theme. This necessitates manually re-selecting my preferred theme each time I log in.

This issue is a minor inconvenience, but it disrupts my user experience. I would appreciate it if you could investigate this behavior. I am using the latest version of Firefox on Windows 11 Pro.

Thank you for your time and attention to this matter. I look forward to a resolution.

Sincerely,

Clóvis Lauriano [edited email from public]

Hi, I have Firefox for Android running on my Samsung Galaxy S23 and the windows version on my PC. Both are logged in to the same Firefox account and are syncing fine. On my PC, the password manager is working as expected and autofilling website passwords.

However, on my phone, I can't seem to get the autofill to work. I have been needing to go into the password manager and copy the password every time. It will ask to save the password and the password manager has everything stored as expected. Tried various things like logging in and logging out but nothing has fixed it. I did notice that Samsung Pass often pops up during the website login process and was wondering if this could be the reason Firefox password manager is not working for autofill.

Your help would be much appreciated. Thanks!

Hi, firefox deleted my history after an update. The only browsing history i have left is yesterday and today since after the update. My bookmarks and the session i was in were still there.

I only have one profile. i dont have a index.dat file unter C:\Users\<myname>\AppData\Roaming\Mozilla\Firefox\Profiles. Any data recovery tools cannot find one either. about:cache only shows me the history after the update.

I dont know what to do and now i've lost my history of the last about 8 years. Does anyone have an idea?
