version - 68.13.1

[Methen]

I decided to try and get version a try The first thing I notice is that extensions that I use are not working they down load and install but they do not show in the bar at the top of the screen the ones that I use are

https://addons.mozilla.org/en-US/firefox/addon/sound-booster/

https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/

That and the utorrent will still not work

Also when ever I try to talk to a friend on face book messenger it will start off ok but then I start getting lags and the messenger will start jumping up and down, when I close the browser and reopen it it fixes the problem for a few moments and it starts again which is very annoying
