Firefox Community Forum

Hello, I am having a problem with Mozilla Firefox on Windows 10.

Firefox sometimes keeps loading continuously and some websites do not open properly or take a very long time to load. My internet connection is working normally, and the same websites may work better in another browser.

I have tried closing and reopening Firefox, restarting my computer, and refreshing the website, but the problem still happens.

Please help me check what may be causing this problem and how I can repair or reset Firefox without losing my bookmarks, passwords, and important data.

Thank you.

I often hit ^T (control-T) in firefox without meaning to, because I use that chord in other applications a lot. In firefox it opens a new tab, which is almost never what I want. I'd like to suppress that keyboard shortcut. I tried doing it using vimium (unmap <c-t>) but that has no effect.

Thank you, Silvio

I just upgraded my Dell desktop from Windows 10 to Windows 11. Virtually all software works fine, and I can sign into Yahoo / ATT email using MS Edge, but when I attempt to sign into Yahoo email via Firefox, sign-in fails and says "something has gone wrong". I am stuck. Any suggestions on how to fix this bug??

new install of firefox won't load accounts.firefox.com

other browsers on the computer load it fine

I've imported bookmarks and passwords and stuff, and since refreshed firefox but can't find a way to fully restore it to initial settings, even uninstall and reinstall won't do it

I had to re-instal Firefox because I had problems with the latest update and now there is no fox icon top left hand corner and no file, etc., so I cannot send email link, print, etc. I would love for someone to assist me.

Got new desktop and cannot retrive my bookmarks. Granted old machine was 16 yrs old. I'd figure Firefox would have have a back up system. I'm 70 years young and this has got me scraching my head!!!! Not a computer expert. Thanks George

Hi,

I've been getting a glitch while typing emails in Outlook Web Access for the last couple of days where superscript type in dates looks like the image attached. It was working fine until sometime this week. I've tried using Microsoft Edge and the issue doesn't happen so I'm thinking it might be browser specific.

I'm running Firefox Version 135.0.1 (aarch64) on a Mac Studio with Sequoia 15.3.1 (24D70).

Can you advise please?

Thank you very much.

Calum.

Receiving Popups in Firefox Trojan Virus found, System Warning.... every time I close or dismiss another pops up. It indicated it was from McAfee at first, now includes websites I removed from Notifications... I scanned via Webroot 4 times now No threats found, None removed.... So I shut everything down and rebooted. Came right back up.

I am afraid to log into anything including email but I need help ASAP!!

Hi - I have TextHelp's Read&Write tool through my university, when trying to install the firefox extension i'm getting a notification saying that it can't install the extension because it's corrupt. I'm not sure what I'm missing but it'd be really helpful if I could get this onto firefox as I move away from google haha!

Any help to get this onto chrome would be appreciated! Thanks :)

Due mostly to upgrades in the app software, it's necessary to restart Firefox on occasion. Also, it's necessary due to OS upgrades. While the Restore Previous Session is a wonderful feature, it arbitrarily (and properly, by default) forgets all of the Private Tabs. But, there are times when I'd like to save some or all of the Private Tabs I've got open. A 'settable' feature to 'Remember Private Tabs during Restart' would be a tremendous asset at times.

After an unwanted and un-needed update, all my tabs closed and I can't find them again. Then after rolling the browser back to a previous version, now all of my bookmarks are gone. I want them back where are they on the hard drive.
