I try to entrer a website www.wizink.pt and the following message appears

400 Bad Request Request Header Or Cookie Too Large

How can Ichange the settings in order to solve this?

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.

send me an email

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

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. What does this mean and how do I reach my netaddress account?

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!

I am a designer of Systems for Sustainability and Renewable Energy. I am receiving the message "HTML5:Video file not found" when trying to watch videos online which is stopping me from viewing a lot of new video content.

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

Report errors like this to help Mozilla identify and block malicious sites

I can't access my company website via Firefox for some reason. Very odd... This just started happening today. http://www.buckaroo.tv/

Error 530

Site is frozen

The page could not be loaded properly.

I am sure this is well known, but I could not find any reference to it.

Get this on various sites, but one it TUBITV.COM. One video file was ABOVE THE LAW and attempt to access gets a "Digital Rights Management (DRM) Error" (see atch).

Is this going to be fixed anytime soon? (Or is there something I need to do?)

Thank you.
