Firefox Community Forum

I have Windows 7, and for the last few months whenever I search I'll often get this error message many times: "Sorry, something went wrong on our end." Very time consuming and frustrating.

Hi everyone,

I'm a website owner and not very technical, so please bear with me.

One page on my WordPress site does not display correctly for me in a Firefox Incognito window:

https://towalisoviejo.com/blog/towing-with-a-tow-strap/

What happens: - In Incognito, the page content sometimes doesn't load correctly. Refreshing doesn't fix it. - It only happens in Incognito. In a normal Firefox window the page looks fine. - Sometimes it starts working again if I change my IP address or turn on a VPN. - It is not constant. Some times it loads fine and other times it doesn't.

My questions:

1. What could cause a page to break only in Incognito? I know extensions are disabled there and there is no saved cache or cookies, but I don't understand why that would change how the page loads.

2. Why would changing my IP or using a VPN make it work? Could this be a caching, DNS, or network issue on my side, or does it point to a problem on the website's side?

3. What is the best way for a beginner to find out what is failing? I opened Firefox DevTools but I'm not sure what to look for in the Console and Network tabs. If someone can tell me what errors or failed requests to look for, I can share screenshots.

4. Is there anything I should test first, like clearing DNS cache, trying another browser, trying mobile data, or turning off Chrome's secure DNS or other settings?

I'm using firefox on windows. Thank you so much for any help.

Canadian provinces of BC, AB, and MB are all moving to new timezones on Nov 1, 2026.

Firefox still does not support any of the new timezones. This will break automatic timezone support for many applications, if not addressed immediately.

For the new timezone: Pacific Time (British Columbia): - Intl.DateTimeFormat().resolvedOptions().timeZone returns "Etc/GMT+8" instead of the expected value 'America/Vancouver' - new Date().getTimezoneOffset() returns 480 instead of the expected 420

There is only a few days left to address this issue. What is the rollout plan for the required updates?

Thanks.

I am generally using Firefox and I can't access the above website that I have always previously been able to access. I have recently changed my computer to Windows 11.

Greetings, After a recent Firefox update, I can no longer login to my Yahoo account in a normal window. I can sign in to Yahoo from a private Firefox window, using Chrome in both regular and private windows, as well as Safari regular and private windows. I have cleared cache and cookies for all Yahoo websites, restarted Firefox and my Mac, no joy. I have checked that I have the most up to date version of Firefox. Since I can login from a private Firefox window, and all other browsers' windows, there is clearly something on Firefox's end causing this breakdown when using Firefox's standard browsing. When trying to login, I can get to Yahoo's sign-in page, several ways (logged out and tried logging in), I type in my username, click Next and it spins for 15 seconds then immediately shows an error message in a new window. The error message is shown below:

An error occurred while processing your request.

Reference #97.8e09c617.1794211833.68184b03

https://errors.edgesuite.net/97.8e09c617.1794211833.68184b03

I have also tried logging into different Yahoo, AT&T and Google accounts, they all work fine except for my legacy sbcglobal account username, which is what I need to use for my Fantasy Football - this same username works on other browsers so it is not an AT&T/Yahoo issue.

I am using Chrome now as I cannot manage Fantasy Football in a private window.

Please advise a fix for this. Thanks Tracy

Yesterday I could not load spectrum.net or my spectrum webmail (I have gmail but mainly use webmail). I called spectrum and they said clear your cache on Firefox, which I did and then it worked. Today I ran into the same problem and tried clearing the cache again. I used Firefox private window to view my webmail (both yesterday and today) but I couldn't log out today; spinning circle (I closed the window and could log back on the next time). Yesterday I could log out using the private window. I don't understand what is going on because I didn't have this problem just several days ago. Thank you.

I receive this message from ebay.ca 431 Request Header Fields Too Large -from ebay.ca My phone can get ebay to load Thanks, Ronn

I get error code: PR_END_OF_FILE_ERROR using Firefox 159 arch 64 (Tahoe 26.6.2) when I visit these sites:

https://calendar.bytewriter.com https://mail.bytewriter.com https://drive.bytewriter.com https://groups.bytewriter.com

The CNAME entries and Google Admin account settings are correct.

I get no PR_END_OF_FILE_ERROR errors using the URLs this way:

https://calendar.google.com/a/bytewriter.com/ https://mail.google.com/a/bytewriter.com/ https://drive.google.com/a/bytewriter.com/ https://groups.google.com/a/bytewriter.com/

There are no errors using Firefox in a private browser, Firefox on an iPhone, Firefox on iPad, Safari or Chrome.

There are no errors when I create a new blank profile. That makes me suspect some sort of corruption in bookmarks and history.

I took these steps: Turned off all extensions - no errors Turning on any extension created PR_END_OF_FILE_ERROR

My web hosting tech support suggested duplicating CNAME entries at GoDaddy. GoDaddy said the web host is authoritative for DNS, and changes at GoDaddy would be ignored.

GoDaddy suggested these steps: Clear all site data for bytewriter. The error persisted except with a new blank profile temporarily disable DNS over HTTPS, then reload https://calendar.bytewriter.com - error persisted In the address bar, go to about:networking#dns Click Clear DNS Cache Then go to about:networking#http3 Click Clear All HTTP/3 Alt-Svc Mappings Close Firefox completely and reopen it Test https://calendar.bytewriter.com again Does calendar.bytewriter.com load after that? -error continued

Search for network.http.http3.enabled Set it to false Close Firefox completely and reopen it -error continued

Deleted Firefox and installed from scratch - no errors Created a new profile and imported bookmarks and history

I work solely for nonprofits and rely heavily on Firefox in training less skilled people. My workaround is to use these until FQDN works without that error
