Firefox Community Forum

i dont know why but when in fullscreen sites have weird borders around them it seems to be a firefox issue i dont know how to fix it.my computer runs windows 11 if that helps.

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.

On gmail "https://mail.google.com/mail"

I am already logged into my main account, when I click on my profile picture in the top right in order to add accounts/sign into other gmail accounts, I get this error:

"403. That’s an error.

We're sorry, but you do not have access to this page. That’s all we know."

I tried clearing cookies and no help.

Bare in mind this is on a fresh firefox install on a new desktop, I have been using firefox on my other desktop with no gmail issues like this.

When I try to log into the site, the system sends a 2FA code. I enter the code an Firefox goes into a loop waiting for the server. When I use Chrome, I get right in. I do not want to be forced over to Chrome. How can I fix this?

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

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!

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.

I use photopea.com for photo editing and stuff, but I accidentally clicked on the option to have that site not show a pop-up asking if I'm sure I want to leave the site and asking if I'm sure I want to close a project. Now I can't close projects at all.

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

Get pop-up (or whatever you wish to call it) while browsing. No way of clearing it.

It does not show in Task Manager. Closed all the Google (first name) processes no change.

Went into firefox help then closed help tab and then original tab OK.

When signing into google on a fresh install of FireFox this is the message I get:

Couldn’t sign you in This browser or app may not be secure. Learn more

Other support tickets about this problem are on browsers like Chrome and Brave, can't find a single one that is about FireFox. Please help.

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.

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.

Hey there, so on this page there is a video element inside of a div. Both the div and video have a border-radius styled in css. This renders as expected on most browsers, but seems to have a potential issue on Firefox on Widows 10 where the video does not have the border-radius and shows up with square edges. Any thoughts on this? If you try other browsers or Firefox on anything besides Windows 10, it is round like expected.

Ok, so this is an odd one.

I gamble with William Hill online using Firefox as my browser.

Every year this same problems happen when the clocks go forward in spring time here in the UK.

So I go on the WH website Sunday (for example) at 11pm and it will show me Mondays football matches. But. At 12am Monday until 1am, the now todays football matches do not appear. Its like the browser can no accept this time period exists because as soon as 1am comes, the matches (for Monday) appear.

So I contacted WH for support. They advised that if I am using Firefox that I should try IE instead. So I did. And guess what? The problem doesn't happen on IE. Mondays matches do exist between 12am and 1am. So it is definitely a firefox issue.

But the issue resolves at the end of October when the clocks go back.

So what is going on here? Any solutions? This has been going on several years.

Directv streaming has been operational since I signed up a few weeks ago until today using FireFox browser except today. After signing into Directv , the channels display correctly but will not open for viewing. Need guidance on the fix.
