Tabs of Gmail not working in Firefox Browser even after clearing history, cookies and the issue persist after logging out and re logging in. The issue doesn't happen in other browsers.

I have an Arch Linux installation with Plasma desktop. Software is always kept up-to-date. Sometime recently, Mozilla apps, Firefox nor Thunderbird, will no longer print, neither to pdf nor to network printer. These always worked before. Now, if even "print preview" is invoked, the dialog opens as a blank sub window with only the word "Print" in upper right, and at left center is "Preparing Preview with rotating time delay wheel, which never resolves. All other apps, including other browsers and mail handlers, will print without issue. I've tried the obvious checks with no success. Where could be the problem? Is there a helper app shared by Firefox and Thunderbird that could be the issue? The only potential remedy I have not yet tried is complete removal of both Firefox and Thunderbird, as that would cause re-configuration issues for both. It's necessary to press <ESC> to terminate the print window when it fails to respond. Screenshot attached...

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

My YouTube homepage is blank when I visit using Firefox (see attached screenshot). Here is a list of all of the fixes I have tried:

-Disabling all extensions and turning off Enhanced Tracking Protection (at the same time) -Clearing cache -Clicking 'forget this site' on YouTube in my browser history -Restarting my PC/Firefox -Refreshing Firefox profile (this worked, but the issue returned after an hour) -Changing my system theme to light mode -Launching Firefox in troubleshoot mode -Logging in on an incognito window (with the same result) -Probably some other things I'm missing (I tried pretty much every result I could find from looking up 'YouTube homepage is blank' and 'YouTube homepage not loading).

The issue only occurs on Firefox and only after I log in to YouTube. This has never occurred before. I checked to make sure my Firefox and YouTube settings are the same as they've always been.

YouTube videos load fine as long as I paste the direct link into the URL bar, but ONLY the video (no comments, recommended videos, likes/dislikes, description, etc...) and I can't take it out of theatre mode nor fullscreen it (fullscreening it just removes the top bar of the browser--the video itself still has black bars on the sides).

Sometimes when I reload the page, I see the following at the end of the URL: &ThemeRefresh=1. I don't know if that means anything.

I am using the Firefox app on Windows 11. I am not using a VPN. This issue is specific to YouTube and YouTube only.

Any help would be greatly appreciated. Thanks!

i write an email and it automatically goes to the outbox,.... but it never is sent. my sense is that it's trying to send emails via another browser... not firefox and it just locks it up.

Youtube is nonfunctional on firefox as of April 29 2025. It was all working fine last night, then I woke up to no youtube. It loads the website as a blank screen. Videos can be accessed by going directly to their URL, but no recommendeds load in, no comments section, even the title and channel information is unavailable. I would say none of the buttons work, but there are no buttons to test. It works fine in Chrome still. I know it's not my extensions because I tried removing them all, and it didn't fix it. I know it's not my cache/cookies, because I cleared that too and it didn't fix it. I know it's not on Youtube's end, because it works fine in Chrome. I know it's not an update issue, because I updated my browser and it didn't fix it. Please. I want to be able to use youtube in firefox. Please help me fix this thing. I have attached photos, but I suspect they'll be more demonstrative of the problem than useful for troubleshooting.

When I go to the task bar and click on firefox the only thing that comes up is, top left corner it says new tab but nothing opens after that, just blank screen. I want to use firefox as my browser but if this continues I'll have to use a different browser.

YouTube videos show up as "video Unavailable".. I can see and talk in the Chat but the video OR Live Stream is shown as "video unavailable".. This only happens in FIREFOX which is my main browser. Now if I sign out, I can watch the Live Stream OR video, but CAN NOT use the Chat, IF I am SIGNED IN, I CAN use chat BUT not see the video.

I am now using (which I hate using)Microsoft Edge to see the video and chat. I WOULD LIKE to be able to use FIREFOX again! Please Help

Firefox has stopped obeying target="_blank"

Started a month or so ago.

Take a look at Firefox target="_blank" problem for details.

There is not a topic in the dropdown list that remotely addresses this issue so I just selected Performance and Connectivity for the hell of it.

i can't watch a streaming movie without it stopping to buffer through out the whole movie . I never have a problem watch TV shows. It wont upload the stream long enough to keep playing . Can i increase the streaming a head so the movie doesn't stop playing till the end.

I use Zen Browser, and since updating my MacBook to the latest OS, Seqouia, my Zen Browser iCloud Passwords extension doesn't work. I'm prompted to update my MacOS to Sonoma or newer, which I've, of course, done. I'm wondering if there is a workaround or if this is simply a bug that needs fixing.

I normally put the computer to sleep at night, rather than powering down (although I do that periodically). After waking the computer, and clicking Firefox open, the browser loads with the two or three tabs I last had open, and within the minute closes. There's no warning or pop-up window saying what happened. I open it again, and within the minute it closes again. This happens four times. On the fifth try, Firefox opens without the previous tabs and with just one "New Tab" showing. After that it's fine. Also, it doesn't happen if I wake the computer and let it sit for a while before sitting down.

This is an oddity that I can live with. I'm just curious about what's going on.

Thanks, Ed LeRoy

I have started to get very frequent tab crashes (all tabs) with "Gah. Your tab just crashed." message. Closing Firefox and starting it again fixes it for a bit, but then it happens again. Firefox is automatically updated. I am not aware of any recent changes to my (quite old) Windows 10 laptop, no new app/program installations, etc.

Any suggestions?

I'm using Firefox 137.0.2 on a MacBook Pro (M4) macOS Sequoia 15.4.1 . I just installed Multi-Account Containers, and have a question that's not answered in any support material I can find.

Before I installed Multi-Account Containers, I had several Firefox windows open, each with many tabs. For each window, I used "Bookmark All Tabs" to save that windows set of bookmarks in a separate Bookmark folder, e.g. "Weather Obs&Forecasts", "Reading_news", "Music & Language", "Reading_miscellany".

Is there a way that I can open a new window and open all the websites in a bookmark folder at once in a single container? (I have in mind making use of Bookmarks > Reading_news > Open All in Tabs .) Because opening a new window, opening a new tab in a container, duplicating that tab 10 times, and then using Bookmarks > Reading_news to open each of the bookmarks in one of those new containerized tabs was a real drag.

Every day Firefox logs me out and I'm required to go thru the whole sign in process again. Have been using Firefox for many years and never had this issue until the past 3-4 months. In the past, each time I opened Firefox I was connected/signed in to my account and my commonly used websites recognized me. Recently has become a major hassle and strongly considering using another default browser that will not have these issues, but would prefer to continue with Firefox if it would consistently maintain my account staying sign in.

We've changed WiFi providers from Comcast to a fiberoptic system that gives us a 2.4 network and a 5G one. For both networks, Firefox will allow some websites to load, some of the time, but not all of the time and usually it won't bother with images. For other websites, the connection just times out completely. If I switch back to the older Comcast networks, the Internet works without issue, but those networks won't be available for much longer. Firefox on my phone is doing fine, but it's like this when I try my old laptop, too.

I have gone through this article. Made sure Firefox can get through the firewall. Poked at the proxy server settings; nothing changes whether it's off, auto-detect, or using system proxy settings. Disabled IPv6. Disabled DNS Prefetching. Cleared my cookies and history. Checked for malware. Gone into Troubleshoot mode to see if it's an extension. Nothing helps!
