Diễn đàn hỗ trợ Firefox

So when I open some websites such as the RimWorld wiki ( https://rimworldwiki.com ), whenever i scroll my gpu for firefox launches straight to 100% and becomes extremely laggy. I have no idea what is causing this. My friends and other browsers run it completely fine. I have tried troubleshoot mode, gotten rid of all my extensions and themes, removed all cookies and cache and nothing works. My drivers are all updated, and I have truly just given up. If anyone has any solutions I would be much obliged.

Can’t login to EFTPS.gov using Firefox and Login.gov. I receive an SSL error message.

Hi! I recently lost my old laptop and I'm trying to setup my new laptop without a backup. I was logged into my mozilla account on my old browser before I lost it, but I'm not seeing any of my old tabs, bookmarks, and extensions from my old browser syncing to my new browser. Is there anything I can do to retrieve this data without having access to my old laptop? Thank to anyone who can help!

Mozilla is asking for a Master? Password. Well, I don't recall setting one up. But to change to a new password, I have to have the original password. Since I don't have that, what can I do to set up a new password?

When I try to load "Comments" I get this message:

Failed loading comments! Please try again...

Trying again doesn't help.

This is a fairly recent problem

Thanks for your help.

I cannot access certain sites, especially those with "book" in the address. Tried almost every idea presented on line with Firefox browser on Windows 11. What is the answer? Thanks

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.

Just switched from PC to Mac and miss the Page Up, Page Down, Home and End buttons. Wondering if there's a Firefox addon or extension to add these functions to a Macbook. I've searched but not found anything. I know I can't be alone in wishing for this!

(I am aware of using "Fn" and the arrow keys on a Mac to do page up and page down, but they are opposite sides of the keyboard and require both hands to scroll by page.)

I regularly use a website which intercepts command-option-up and command-option-down for its own navigation. This is a central part of my workflow with this website, and without it it becomes completely unusable.

After updating to Firefox 140.0.4, these shortcuts are now used by the browser to switch tabs. I have not found any way to configure this. Am I missing some obscure way to do this or is this just impossible?

I imagine this change was made to support vertical tabs, but I'm not using those, so the command-option-left and command-option-right shortcuts make more sense for my horizontal setup. (I don't use those shortcuts either, though- I use ctrl-tab and ctrl-shift-tab!)

Hi,

Not sure if anyone else is reporting this but ever since the last update - 140.0.2 Firefox Release, June 27, 2025 - many of my general sites, yahoo, news, company sites that I use everyday, do not load. I have to use Private Browsing, keep refreshing or change URL for the site to load. Anywhooos, I do appreciate you guys! keep it up!

Добрый день! Я создавал аккаунты через расширение мульти-аккаунт в браузере и сейчас все аккаунты удалились с браузера. Есть какая-то возможность вернуть аккаунты? Их было очень много и они очень важны

I downloaded firefox and it worked for about a month. Now when I try to launch it, the screen flashes momentarily as though it were about to pop up, but then it does not actually open a browser window. I have uninstalled and reinstalled firefox more than once, I've tried a simple restart of the computer, and tried multiple different update methods (updated windows). Any suggestions?
