Firefox Community Forum

every time I try to log into a google account I get a 400 error message. I deleted all cache and cookies multiple times scoured the help forums and tried all the fixes and I still get a 400 error. please help.

I have never had a problem opening my email client before in Firefox, but now after the last time I started my computer I get this message when I try to open my email client (Shaw Webmail):

400 Bad Request Request Header Or Cookie Too Large nginx/1.24.0

Oddly though, it will open if I go into the Incognito window. Why is this happening and how can I fix it so I don't have to constantly into Incognito mode to access it?

1, provide phone support....which i am willing to pay for.

2. fix it -- remove the problem via an update

3. A new computer....and I still get this "Application error: a client-side exception has occurred (see the browser console for more information)." WHY ? Of course, GREAT that Mozilla never has real people to staff tech support.

I have an issue where I will frequently get the error pictured on random sites. This started happening a few years ago at my previous home with my old computer. It got so annoying that I had to switch to Brave browser for a while. I recently moved to a new residence, I have a new computer, and a different ISP and equipment, so I thought I would give Firefox a try again. To my shock, the issue still occurs exactly the same way at the same rate. I would say it is as frequent as 1 in 5 sites that I visit. If I hit the Try Again button 5 or so times, the site will load. The only thing I can think of that is common to the old computer and the new one is my Firefox account. Could there be something in my settings causing this to happen? I remember that I even tried Librewolf before switching to Brave but the issue occurred there as well. Any assistance or tips would be appreciated, I feel like I am going crazy at this point. xD

I subscribe to my city's newsletter. It gives quick links "click here" to register for a class, "click here" for information about an upcoming parade. I used to be able to click and get it. Now it tells me It can't find the site OR I might be connected but behind a firewall. There are too many options and too many terms, I don't know what to do, I just want to click links from my city newsletter, and get taken to them. Help???

Hmm. We’re having trouble finding that site.

We can’t connect to the server at vu4mbwlab.cc.rs6.net.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

I keep getting 'Bad Request

this website is not browse getting error - Warning: Potential Security Risk Ahead

When I sign in to ssa.gov to see my personal record, the link takes me to a new tab with an error message. This does not happen on my mobile phone with Safari. I would like to use Firefox on my laptop but it will not let me access the Social Security link provided on their website. The URL: https://www.ssa.gov/personal-record When I click on "View your record"..."Sign in to view your earning record....." It opens a tab with this URL: https://secure.ssa.gov/RIL/SiView.action with the message: Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. This must be a Firefox problem since Safari has no problem with this link. I prefer Firefox, so please help me find what the problem is so it can be fixed and I'll be able to use Firefox to access my Social Security account. Thank you!

I have only had this computer since Christmas and I have no idea how to use Windows 11. I seem to be able to go to other websites Bank of America no problem but time out message every time I try to go to my e-mail

Good day,

I'm using Selenium with Firefox in Python to automate browser testing, but I keep encountering captchas that prevent my script from proceeding. Additionally, I receive an error stating that "the browser is being automated" (Reason: Marionette).

My intended automation flow:

1. Open Firefox
2. Go to www.google.com
3. Search for "YouTube"
4. Click on the YouTube link
5. Search for a video
6. Play the video

However, captchas appear during the process, and I suspect it's because Firefox detects that it's automated. Is there a way to disable automation detection in Firefox or configure Marionette to reduce captchas when using Selenium in Python?

Any guidance or workarounds would be greatly appreciated.

Thank you!

Can I / How do I resolve this situation?

Hello, when I browse the internet, randomly the certificates seem to break as I get https certificates for sites that seem to have nothing to do with the sites that i intend to visit. Then errors like the ones in the screenshots appear. Usually reloading the website helps and then the certificate displayed seems to be correct. I did make sure to upgrade to the latest version of FF (136.0) and I did clear all cookies, but it didnt help. I do not really have any idea where to start searching or what might cause this, tia for help. kind regards Thomas

Dear Sir or Madam: I seem to have a compatibility problem with my firefox browser. Not always, but often, I get a 502 error when I try to log in to my bank account. After contacting my bank, I found out that their program is not compatible with firefox and that I should use Google, which choose to avoid. Is there a patch or fix that can get rid of the 502 error and allow me to continue using Firefox, which I have used for almost twenty years. I don't want to switch to Google, EVER! Please let me know what options I might Have.

Respectivly, Louis Osip

Just refusing to load websites. Reddit twitch discord other stuff. Tried running firefox in safe mode. Doesn't fix shit. Turned off proxy networks and that worked for a while but problems back now
