I have a website that uses Javascript 'fetch()' to call pages on the server, and no matter what I try, it never works, since around the end of the year. I keep getting the following error:

"Uncaught (in promise) TypeError: NetworkError when attempting to fetch resource."

Can somebody help?

Thanks in advance

Attempting to log-in on Twitch with Firefox Browser - Developer version 122.0b9 (64-bit) is currently not possible, repeated messages are prompted by the Twitch website about "unsupported browser" and to contact browser support to resolve this issue.

Clearing cache, disabling extensions did not work. Using regular Firefox works without issues, only noticed this being an issue after most recent update for Firefox Dev browser.

Side effect as well since update is that any Cloudflare captcha is impossible and all website that use Cloudflare to "authenticate" that I'm human just outright fail or continue indefinitely.

I was trying to resolve a graphics issue with Firefox and Webgl2 on a specific website, so I used a recommended solution in advanced settings, which just spread the problem to other websites. I wasn't really sure what to do at this point, so I tried to just reset all the modified settings to attempt to get back to the first download settings. However, I was unable to do this and now Firefox can't load any pages, even when I've deleted the browser and redownloaded it. How can I get a completely fresh download, or even can I? I'm not tech savvy and extremely frustrated at this point.

This is on macOS Sonoma 14.1.2.

If I copy/type anything into the address bar, and press enter, it disappears and the browser remains blank. As does: selecting any website from the address bar dropdown, opening any bookmark, or attempting to open any file. There is no error, so I'm at a loss how to debug this.

Firefox was working on Ventura. Repeatable with Firefox versions 120-115, have not gone back further. Neither troubleshoot mode nor deleting/rebooting/reinstalling changes anything.

Hi, I installed the new update yesterday. This morning, I cannot access anything through my usual Firefox browser. I'm making this report from Google - which is working fine on the same computer. When I try to access any websites, the usual tab opens with a greyed-out "X" (or hourglass?) on the left of the tab - then nothing happens. I've tried restarting - no luck. I suspect yesterday's update was flawed/had a glitch. Please help.

Videos can't be played at higher playback speed Bug

On firefox, I cant play videos at higher playback speed or it'll only play audio or video will endlessly buffer. Using user-agent spoofer and changing to chrome makes it a little less worse but still the problem sustains. On Brave, the video doesnt have any effect of higher playback speed rather it'll make the video buffer and have very strong red contrast.

Can someone tell me how I can re-enable it for the website?

I'm experiencing consistent issues with my website that seem to result in breakages across various browsers. Despite my attempts at troubleshooting, I haven't been able to identify the root cause or find a solution. Here are the details:

Website URL: [Your website URL] Browsers affected: Firefox, Chrome, Safari, etc. Breakage symptoms: Describe specific issues such as broken layout, dysfunctional elements, error messages, or any other visible problems. Steps taken to troubleshoot: List the actions you've already tried to resolve the issue (e.g., clearing cache, disabling extensions, checking console errors). I've ensured that the website is up-to-date and compatible with modern web standards, but the issues persist. Could someone kindly provide guidance on further steps to diagnose and resolve these recurrent website breakages? Any assistance or suggestions would be greatly appreciated. Thank you!
