When use the built-in button on a video to fullscreen it (Youtube or any other site) then the taskbar will do the animation to go away then instantly come back up. If I use f11 I to fullscreen all of firefox the taskbar does not show. Why is this happening with videos? Using other browsers I do not encounter this issue.

I use a MacBook Air running on Sequoia 15.5. Firefox was updated several days ago to 140.0.2 (aarch64).

Since yesterday, Firefox has repeatedly stopped running. (It might have started sooner, but I didn't use the computer over the long weekend.) It won't load pages. Sometimes I get the spinning wheel. Usually, I have to force quit.

I've cleared the cache, restarted the browser, and restarted the computer repeatedly. Restarting the computer sometimes helps. Now is not one of those times.

Also, the About Firefox window is open, and the Checking for updates . . . wheel keeps spinning.

There are no connectivity issues otherwise with my computer or other apps.

Does anyone know why this is happening? Do I need to go back to the last version of Firefox? Uninstall/reinstall?

I'm getting a PR_CONNECT_RESET_ERROR on my PC when trying to web browse. Same problem with other browsers. Was working fine till a few days ago The URL box has 'Not Secure' before each URL address I try. Have looked up solutions on YT to no avail eg clearing cache etc

My Laptop has no problem with this.

When I click a link I always want it to open in a new tab. How do I do this without doing a right-click and selecting "Open in new tab"?

I want it to open in a new tab when I simply click the left mouse button.

Attempting to bill pay at Allstate page, stating the browser is not compatible. What options do I have? I have been using Firefox for > than twenty years, I have a hard time trusting anything that comes from Microsoft after their internet explorer debacle .

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?

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

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?
