Firefox 39 crashing
After many attempts, I have a fix for this. The problem lies with Firefox version 39 and the Flash plugin. Either the Adobe or the Pepper flash.
What I have done is totally delete the flash plugins, install the Pepper flash, and download Firefox 39 from Mozilla, and overwrite Firefox 39, which came from the Ubuntu repositories.
The very first thing is to delete all Adobe flash installations
dpkg-query -l | egrep 'flash|fresh'
Now delete these with the purge option, using the file names returned from the dpkg-query command:
dpkg --purge <file_names>
Now you can install the pepperflash from webupd8:
sudo apt-get install pepperflashplugin-nonfree
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install freshplayerplugin
Now you will need to download the latest version of Firefox from Mozilla, as the version from Ubuntu seems to have issues. First step is to backup, for just in case something breaks:
sudo tar -cvPpf ~/Firefox-backup.tar /usr/lib/firefox*
sudo wget -P /usr/lib/firefox https://download-installer.cdn.mozilla.net/pub/firefox/releases/39.0/linux-x86_64/en-US/firefox-39.0.tar.bz2
sudo tar -C /usr/lib/ -jxvf /usr/lib/firefox/firefox-39.0.tar.bz2
Now you should be able to start Firefox and watch video without the constant crashes.

I already asked this on Firefox support but still no anwer so maybe someone here knows how to fix this.
After I updated Firefox to version 39 I can't use it at all, it crashes all the time, I couldn't even write this question from Firefox. I clicked on "Refresh Firefox" button, also I restarted with addons disabled, also I reinstalled Firefox but none of that helps. Crashes are random, after 5-6 minutes of browsing.
You can see crash reports here: https://support.mozilla.org/en-US/questions/1071421
EDIT: I installed developer edition of Firefox and no crashes so far

MakisH almost 9 yearsI also have this problem! It has crashed at least 20 times today! Do you think we could hope to an update to fix this? I don't want to change my firefox branch.

Alen almost 9 years@MakisH It should be fixed soon, many users reported this issue: support.mozilla.org/en-US/questions/1071421

MakisH almost 9 yearsFor me it was probably the freshplayer plugin. I removed it and it is now stable again! :-)

Admin almost 9 yearsIf you disable Shockwave Flash plugin, you could fix this problem.

Alen almost 9 yearsI did everything you suggested but it's still the same. Is there any chance to revert to version 38?

ALAN WARD almost 9 years@Alen Added the information to my answer. Short version: no, it does not seem possible. Either you get version 28, or 39. I am starting to think your upgrade was incomplete, with some packages that were not completely installed. Were there any error messages? In any case, "aptitude safe-upgrade" should be able to help.

Alen almost 9 yearsNo, there weren't any error messages. Thanks for your help, I installed developer version and it's ok now, version 40 will be stable soon so I hope it won't cause any trouble.

ALAN WARD almost 9 years@Alen So it seems the problem was with this particular version - and you were quite right to make a bug report to the Firefox project.
