[Bug 1058209] Re: firefox re-installs Add-ons everytime I restart Ubuntu

[xDfg#$]

Ok, so this is what I did:
Firstly, I removed Adblock plus. After a restart firefox asked me again if I want to install all of my extensions including ABP (although I removed it). 
I removed it again and started to remove each add-on with a reboot after this. Sometimes it took me two reboots to reproduce the bug. I removed all of them except "Easy youtube video downloader".
It seems that it stopped after I removed "Https everywhere". After few restarts it didn't happen again.
I reinstalled "Https everywhere" to see if it would came back, but it wouldn't.

This are the logs from the error console:
#This one is before removing anything:
