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.

I get this error message:

The proxy server is refusing connections

Firefox is configured to use a proxy server that is refusing connections.

   Check the proxy settings to make sure that they are correct.
   Contact your network administrator to make sure the proxy server is working.

What do I have to do to fix this?

The old profiles had my logins for work. I would prefer not to have to spend hours resetting something like 15-20 logins and profiles and then the next two months forgetting what the new ones are.

When you open a new tab a "snippet" is shown at the bottom of the page. According to the preferences this is for "Updates from Mozilla and Firefox".

Now I'm starting to see messages about how I can fight racism and how I should be proud of who I am.

Is there a way to limit the messages to things that are actually related to Firefox? I want to see important technical updates. I see enough political statements everywhere else.

Please see attached image. Whenever I try to install an extension on firefox quantum 68.2.0 ESR it simply shows a greyed out button I cannot press. The only article I can find on this offers the solution that it can be fixed using another plugin (which I can't install for the same reason...)

User-defined keyboard shortcuts on Mac don't work, unless menu item has been displayed

I've assigned user-defined shortcuts to Firefox on my Mac by adding items to:

    System Preferences -> Keyboard -> Shortcuts -> + icon. 

This method works fine in other applications. However, within Firefox these only work after I've clicked on the menu bar and displayed the item with the shortcut.

For example, I have a shortcut to show the Bookmarks Toolbar defined as "View->Toolbars->Bookmarks Toolbar." In Firefox, under View menu I see the item "Bookmarks Toolbar" with the appropriate shortcut key shown next to it. BUT whenever I open a new window I have to show that menu item again before the shortcut key actually works.

Is this a bug?

I've tried different shortcuts, turning on/off private browsing, defining shortcuts under "All Applications" as well as "Firefox.app"

Thanks in advance for your help!

I've literally checked everything, reinstalled firefox, checked audio, set default audio, etc etc.

Every other browser plays audio, every game plays audio, every media player on my pc plays audio.

I can see the firefox audio going up and down like it wants to play but nothing is coming out. I'm a tech savy guy with computers and I can't even get this to work! It's stressing me out, started 2 days ago and hasn't gone away, didn't install anything new either.

I've double checked and triple checked my computers audio settings, even did a remove performance thing within firefox that says it can fix. doesn't.

Many times lately, when i get a reply to an email I've sent, i can't read the reply. I'm on a mac book pro. I just tried clearing history for the last hour but that didn't help.

I can only read it if i go to Google Chrome .

And on GC, after being there a few minutes, all of a sudden i see it has changed to " site not secure". 

Thought it was because i was on wifi but it happens even NOT on wifi.
