..have decided to upgrade my version 45.0.2 (which was working fine..) to version 46.0.. but when i try to run firefox again, it wont even start... as in nothing, no error message, as if no app was there.. i tried restarting the computer but still nothing.. i tried creating and using a different profile, but still nothing.. downloaded the firefox-46.0.tar.bz2 file, extracted to a new directory and start from there.. but still nothing.. what seems to be the problem...? why wont firefox start at all..? i have a copy of the firefox-25.0.tar.bz2 and did the same thing and it worked.. so my working firefox version is now version 25... when i tried to upgrade it to the latest version, again it didnt work again.. is this a version 46 problem..? is this a bug with version 46..? im trying to find a copy of version 45 and will do the same.. if this works, then its probably a version 46 issue.. what do you think..?
