Some Youtube videos say "Your browser does not currently recognize any of the video formats available. "

and Amazon Prime "Video Unavailable" is also fixed by this.

I fixed this by installing FFMPEG which installs libavcodec.so.58

DRM Playback is enabled under preferences.

Hi, I'm on an updated Arch Linux system.

Something went wrong (maybe testing audio settings with JACK and PulseAudio alternative 'apulse') and Firefox hanged and had to be killed (probably '$ killall -s SIGINT firefox' or something similar).

From that moment I couldn't start again Firefox with my profile. But any other profile works fine.

I've got this:

``` $ killall -s SIGINT firefox $ Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. [GFX1-]: Receive IPC close with reason=AbnormalShutdown Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error.

$ firefox ExceptionHandler::GenerateDump cloned child 2087 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... ```

Already tried --safe-mode but without success. Keeps crashing.

Any ideas?

Thanks a lot!

Noticed that silent printing doesn't work starting from new Firefox 78. Now I can't even find "print.always_print_silent" settings in about:config using this instruction:

   Set up the receipt printer as your default printer in the Devices/Printers screen.
   In Firefox, type in “about:config” and hit Enter.
   A dialogue box will appear, press “I’ll be careful, I promise.”
   Right click, select New | Boolean.
   Type in: print.always_print_silent
   Select True, then OK.

Could you please, maybe this setting was renamed or deleted?

After updating this morning (I'm not sure if firefox was upgraded at this point) and restarting my computer firefox now exhibits a strange behavior. Every page I open it automatically scrolls through every scroll bar on the page. Thankfully most pages have only the one, down. However, if I get on a page with lots of iframes it will automatically scroll through each one of them in turn as well as scroll to the bottom of the page. I can't seem to interrupt this process until it's completed. Once it's done I can scroll back to the top, or correct any horizontal/vertical iframes and continue on as normal.

I've followed the instructions at https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems to no avail. I've opened firefox in windows as well and it doesn't seem to have this behavior. I've started in safe mode and it still does it. I manually turned off each plugin as well one by one and still, this problem persists.

For reference: Kernel version: 5.7.7-arch1-1 application.architecture: x86-64 application.buildid: 20200701193652 application.version: 78.0.1

Hi,

About 4 to 6 weeks ago I messed up my main/home/Whatever named file:///home/kline/.mozilla/local/hotlist.html <an html file with 2-deep links to other bookmarks>. Upon reboot I must have done *something* that messed up everything. The "3-dot", "pocket", "star" was either moved leftward or vanished ... Now that clever 4-icon { |||\ } that used to bring up whatever I had bookmark was gone.

Can anybody help me?

I am unable to login to firefox accounts .

I have the correct Email and Password, but it keeps asking me for the conformation code sent to the email for login, but i dont have access to the Email as the password is saved in sync server.

I mean the Lockwise Sync server. No i don't have any device currently logged in to Sync. I recently Formatted my PC, So all files for password manager were lost(I synced the logins to the server before formatting my pc hoping that the Login id and Password for the Accounts would be enough to retrieve them ) and am trying to retrieve the logins.

No luck with the login links i can login but cannot change anything in the settings, it says :

" NOTE: Before you can view or make changes to this section, you will need to verify your email address. "

So any way i try it is asking for the conformation code sent to my Email address Whose password is stuck in my sync server.

So its like


can't access the sync server -------because------- can't access my email for code------because--------can't access my firefox lockwise -------because-------can't access sync server

Need Help ASAP Please.

Firefox 77.0.1 address bar seem broken. Won't show common sites without deleting anything in the URL bar, no down arrow

I had set the about:config settings after 75 came out to fix the address bar. Today I got 77.0.1 and now the address bar seems broken again. When I mouse over it, there is no longer a down arrow to click and show my common sites. If I click in the bar and then delete everything, the list of common sites appears. If I click away and click back into the blank address bar, now I have to hit the down arrow to get the list to appear. I need a way to get the down arrow back so the address bar works as expected.

These config options are all set to false:

   browser.urlbar.openViewOnFocus
   browser.urlbar.update1
   browser.urlbar.update1.interventions
   browser.urlbar.update1.searchTips
   browser.urlbar.update1.view.stripHttps

Just last night I updated Firefox to version 78.0.1 on Fedora. I cleared all my history. I had to sign in to Firefox account again for some reason.

And this afternoon I discovered that my Logins and Passwords has gone empty. I use master a password and that is still in effect, and my sync settings includes logins and passwords. I've done this many times--signed in to my Firefox account, set up a master password and I'd see all my saved passwords there after doing a fresh install of my operating system. I don't know what happened now.

I looked at the article about keyboard shortcuts, but it didn't say if there was a way to disable any of them. It seems often when I'm typing, instead of hitting the backspace key, I accidentally hit the F12 and it pops into development mode. I won't be doing any development in the near future (or probably any time) so I'd like to disable that one for convenience. Thanks

It seems most answers to this question tell you to clear browsing data and the autofill entries. That's not what I want.

Say you have a form that contains previous data, whether manually entered or autofilled. You want to use autofill for the entire form, but by default it doesn't overwrite fields with entries. How do I clear the form and start fresh so autofill can do its job?

Hello. From time to time, when using firefox I find that firefox-bin process uses very high cpu process (on top command output it shows even more that 100% (i don't understand those specs)) It doesen't seem related to any specific website. I close tabs one by one and it remains the same. Even when closing firefox window, firefox-bin remains using 100% cpu for about 1 minute or so. Then a crash message appears, and I click send report.

Any suggestions accepted. cheers. Firefox 77.0.1 MX Linux 18.3

Whenever I search for a new subject(not pre-searched) no results are shown and I get the message "Hmm. We’re having trouble finding that site". This happens only when I use Duckduckgo to search. I have updated firefox to the latest version, used safe mode, and cleared all my browsing history but none of them have seemed to work. I have been facing this problem since 2 days now and initially I used to get the error message "PR_END_OF_FILE_ERROR". Thank you.
