Firefox Support Forum

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 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?

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.

What would cause websites not responding. I have no malware and the cache is clean. Could it be in the properties, or whatever.

Thank you. It's very frustrating.

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

Hi, Mozilla team I hope that you have a great day, straight to the point, my UI sometimes crashes or some components glitch or don't even work as it has to This is a video below slowed(I couldn't upload the video).

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.

After latest Firefox update this morning, attempts to login to Fidelity.com fail with message "we can't complete this action right now". No problem if I use Chrome. I cleared cookies and rebooted. Running Windows 10. Fidelity technical support not seeing anything obvious but suspicious it is related to this latest update.

Not sure of the topic. When I type in a website that I have typed before, its fine. But, if I search something new, anything, the tab trembles and does not search. I quit and restarted. Updated today to the latest. Still the same. I am writing this from Chrome because Firefox won't even respond to searching for firefox. The trembling is seen in the new tab and nothing happens.

Thank you, Naomi

i was watching youtube when this happened here is the link https://www.youtube.com/watch?v=o25FuR0eUAs the error "your browser cannot play this video"

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,

WSJ opinion pages won't load fully on Firefox. The same webpage works on other browsers. This has been a recurring issue ever since I switched over to Firefox. It's the main reason why I still keep Google Chrome around.

I've tried updating to the newest version of Firefox and also iOS. Also, clearing my cache/cookies works sometimes but the problem keeps coming back.

Is this really Mozilla or Google playing dirty? I ask because the site I was trying to access suddenly has stopped working on other browsers, so I thought I would try it on Firefox, and this is what happened. I do not have the security key it is asking for so I cannot even log into the site. The site support told me that they recommend Google Chrome. It seems too coincidental that it suddenly stops working on other browsers and Firefox won't even let me login. Nor has it EVER asked me for a physical security key to access any site before.
