Firefox Support Forum

Opening a new empty tab is very slowly with the spinning wheel (about 10 to 20 seconds). With no other tab opened. Closing a tab also takes about more than 10 seconds (empy tab, no other tab).

Can not open web sites : almost every times nothings happens. But sometimes it works. Firefox process has tenths of child processes which are <defunct>

What I have tried : - Remove all configurations files (see list below) - Install a fresh Firefox - Restarts the computer (MacBook Pro Intel) - Launch Firefox

That means that I have an empty profile, no external module, no account synchronisation, no history, no bookmarks, zilch, nada ...

Repeated the previous procedures several times the last few months. With : - Mac OS X Ventura 13.5.1, Firefox 117.0 and Firefox 119.0 - Max OS X Sonoma 14.1, Firefox 119.0.1 - Mac OS X Sonoma 14.1.1, Firefox 120.0 - Mac OS X Sonoma 14.2.1, Firefox 122.0

Firefox has a normal behaviour for a few days after each system upgrade. Then the problems comes back.

Other browsers (Chrome, Safari) works fine and smoothly.

But ! TorBrowser, which is built on Firefox, encounter the same problems.

Configurations files that I delete : - ~/Library/Preferences/org.mozilla.crashreporter.plist - ~/Library/Preferences/org.mozilla.firefox.plist - ~/Library/Caches/org.mozilla.firefox - ~/Library/Caches/org.mozilla.crashreporter - ~/Library/Caches/Firefox - ~/Library/Caches/Mozilla/updates/Applications/Firefox - ~/Library/Saved\ Application\ State/org.mozilla.firefox.savedState - ~/Library/Saved\ Application\ State/org.mozilla.updater.savedState - ~/Library/WebKit/org.mozilla.firefox - ~/Library/Application\ Support/Firefox - ~/Library/Application\ Support/Mozilla /Library/Application\ Support/Mozilla

Can not find anything to try.

Any idea ?

Trying to save a web page as a PDF to Evernote; error message Can't tell if this is an Evernote problem or a Firefox problem. 1. Click the "Print" button on the web page. 2. Scroll down to "print using system dialog". 3. Click the "PDF" button and scroll down to "Save PDF to Evernote". Error message appears: "error running print workflow". I've used this function many times before and it has worked with no problems. (I tried the "Mail PDF with Postbox" option on the PDF menu and it works.)

my browser was running insanely slow so i decided to close it out only to open it back up to being logged out, tabs gone (but still synced for now) and at least 1 extension which is now no longer available for download gone! i'm p***ed mostly because the extension (enhancer for youtube) was the only good one of it's kind and now it's gone for absolutely no reason. i did not clear any data or cookies prior to this so why?!

Only one bitchute vid-site won't play in firefox, all other vids play. Other subscribers have same problem. USA Prepares https://www.bitchute.com/video/lsqwdjy27l0w/ https://www.bitchute.com/channel/rongibsonchannel2/

Came here after a response on my google play review.

The problem is exactly as the title describes. Playing videos on various websites, such as Youtube, Vimeo, Twitter and Reddit for example, on firefox mobile (including firefox focus) results in the videos playing back with low fps instead of their native fps.

Refreshing the page the video is on sometimes fixes the issue, than once you pause the video and resume it the problem with the low fps shows up again.

Reinstalling doesn't fix it and downgrading to an older version made the problem occur less, but videos would still sometimes play back with low fps.

If screen recordings help figure out the problem please tell me.

I'm currently looking for a job, and I keep my windows separated by category, so I have one that is job search related, and the other that is more general. In my job search window, I have many tabs open for different job postings that I want to hang on to /keep track of. When I want to jump to one of these tabs, I open a new tab and type in whatever its title would be, and then when it pops up in my history I click the "Switch to tab" shortcut to get to it. I find it saves time as opposed to sifting through 50 tabs. In this case, I was trying to find a tab that was opened to a sales job posting, and I clicked switch to tab. However, it took me to a what I think is an entirely separate window, one that I didn't even have open previously, and my jobs window disappeared. I tried to reopen it in History, but it didn't show up. Does anyone know what might have happened here, and how I can recover that window?

Not sure which is the cause. On multiple laptops and desktops after last Windows 11 update and then an immediate Firefox update, the software protection service of Windows 11 goes into high cpu mode consuming 40-50% of cpu when Firefox is opened. Running Firefox version 122.0 (64-bit) version. Tried in safe mode and still having issue. Just an FYI for developers to look into for next Firefox update.

here is the latest of many crashes documented. I have no idea how to fix this. The problem-solving measues on the Fierfox website were all without success bp-5ab98827-7fab-4757-8baa-db3360240204

authentication required window popups. And do not close with "cancel" or Esq.

The story: I've used proxy but subscription expired, so i do not have working credentials, but I cant change settings cause "authentication required" - blocks everything . how the fuck i turn it off?! options\settings is fucking locked by this pop up.

so for bad english... but have no other words for "this design" to lock everything after proxy pop up.

Hi, I have been quite satisfied with Firefox for a while, but these problems are ruining the experience for me. 1. The tabs keep refreshing when I switch apps or even when I stay on the browser, just by changing tabs and leaving it open within the session. I usually open a lot of tabs, and this has nothing to do with the inactive ones. 2. I used to be able to play YouTube videos in the background or with my screen off on the Firefox browser on my Android phone without problem. But now the audio keeps pausing and doesn't continue to load, even closes itself after a few seconds of loading. Nothing i've done, including downloading the video playback fix addon, clearing cache, restarting phone and turning off and on data saving mode/background data permission, has fixed this problem.

Looking to restore the bookmarks and saved logins. They accidentally ended up in the trash. I retrieved the files from the trash but now have no idea what to do with these pieces as shown in the "Uploaded images". Any advice is greatly appreciated. Hoping someone can say: "this is where the saved login data is located and this is where the book marks are located AND this is where they need to be reinserted. Thanks in advance.

Hello everyone,

i just wanted to post this here so others may find it via google. I had a problem with videos randomly playing with black borders. That was really annoying because sometimes it cut out portions of the video. But after months of trying and searching nothing came out, except the "fullscreen black border 'api-config' fix" wich didn't help me. And now finally I figured it out! It was my damn AMD driver...! It was set to "Home Video" in "Audio and Video", wich enabled "AMD video stabilization".

So in quick summary: When you have black borders while watching video in Firefox; make sure in your AMD-driver, in "Audio and Video", "AMD video stabilization" is turned off!.

Hope this helps someone, bye :-).
