Firefox Support Forum

I have 4 tabs open, and my computer is running and running... come to find out, FF is running 17 tasks in the background... why? And what can I do?

Thanks!

my specs Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz 2.21 GHz 16.0 GB (15.9 GB usable)

I use this addon

Select After Closing Current

But apparently I'm not using it correctly.

When I close a tab, it defaults to the tab on the right, which, to me, IMO, is counter intuitive.

And just as bad, when I restart the browser, it opens to the tab on the right much of the time, instead of the current active tab.

Is there something I can do can do about this?

For the past few days, the YouTube website has behaving unusually in Firefox. The volume and play/pause controls don't work. The picture in picture mode does not work. And most importantly, the search bar is broken. Whenever I type something and click the search button or press enter, the value entered disappears and I have to type it all again, only that this process goes on for infinite number of times and so, I can't even search for anything on YouTube.

Really too much PR_END_OF_FILE_ERROR

https://www.bbc.co.uk/news/uk does NOT have issues.

this error message occurs regularly ( and sometimes with amazon.de)

Please fix the bug that causes this, or allow a option to ignore the (non existent) error.

There is a serious problem here! I have the latest Firefox browser for Windows installed: 118.0 (64-bit). Under Settings, I have the box checked that says: Open previous windows and tabs.

It isn't working. All my tabs keep getting wiped out. I am a developer. I primarily use Firefox because it is the only browser that knows how to display bookmarks in a column. I have many tabs open at one time. I need to pick up where I left off. Now this is completely unusable. Can someone get this back to normal operation?

Please!!

Hi,

I have a Wordpress site with Google Cloud Text to Speech. It works on Chrome. And it has worked on Firefox. Any ideas on how to troubleshoot this?

Thanks!

After a crash and new Firefox update today (September 28, 2023), Firefox is now opening a new window along with every new tab. If I close the newly opened window, the tab on the browser 'main' firefox window also closes. The 'open links instead of new windows' is ticked. I have tried refreshing Firefox and also uninstalling and reinstalling. Running on Windows 10. Please help! Thanks, Robin

Every time Firefox updates, a Firefox shortcut is added to my desktop. In delete it because I already have a shortcut for it in the taskbar. How can I stop this from happening? I have tried turning off automatic updates and manually updating the browser and it still creates a shortcut. It's been happening for over a year and I am close to uninstalling Firefox completely and switching browsers.

So on certain websites when I zoom in these weird white lines and boxes appear on the screen. they only appear when zoomed in and when I put my cursor in certain places. Usually when I move my cursor they disappear but I was able to catch these. Im on firefoxes most recent update on a lenovo laptop with windows 11. As far as I know this only happens in firefox, another thing is I recently updated my drivers due to screen flicker.

Hello!

I chose to switch to firefox recently so I haven't figured out how to fix this. Every time I turn my computer on and open my browser and try to log into youtube, I have to log in again. I can save my password for the site but it behaves every time as if it's my first time logging in. This hasn't happened in other browsers so im unsure if it's possibly google account settings. That's why it was my first assumption it was with firefox. so far other logins work fine for me. Thank you!

I'm encountering consistent video playback issues on Firefox while running Fedora 38. The error message I receive when attempting to play videos from certain sites, notably LinkedIn and Twitter (now X), is:

• The media playback was aborted due to a corruption problem or because the media used features your browser did not support.*

Furthermore, when examining Firefox's console while attempting to play a video, I observed the following error:

• [Child 5999, MediaDecoderStateMachine #1] WARNING: Decoder=7fdb3c55a100 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-118.0/dom/media/MediaDecoderStateMachineBase.cpp:166*

Steps to Reproduce: 1. Navigate to LinkedIn or X (previously Twitter). 2. Attempt to play any video content. 3. Observe the aforementioned error.

Additional Details: - OS: Fedora 38 - Firefox version: Initially 117.0.1, then updated to 118, both 64-bit. - This issue does not occur on Google Chrome on the same system. - I have attempted the following troubleshooting steps without success:

 1. Updated Firefox to the latest version.
 2. Enabled DRM content.
 3. Booted Firefox in Safe Mode.
 4. Disabled hardware acceleration.
 5. Cleared cache and cookies.
 6. Used a Flatpak version of Firefox.

This issue has significantly impacted my user experience, and I hope to find a resolution soon. Any assistance or guidance would be greatly appreciated.

Thank you!

All that was required was synced from my old laptop to my new laptop. But I just cannot find an option to sync my Notes from my old Laptop. I have looked through the Help section but could not find any help. Also can Notes be synced to my Firefox browser on my Apple/Android phone. Thanks in anticipation

I'm using my Firefox with Custom CSS with toolkit.legacy thing enabled. I'm using Firefox for my everything and I love it. But It keeps break my current profile then starts a new profile that everything has been reset. It keeps break my profile and starts a new profile. I lose everything... It's enough for me. I could not find any solution for it. If It's not fixed, I'll stop using this beautiful browser :'(
