Re: Installed 11.10 using Application in Windows 64bit
Hate to be the bringer of bad news ... but the slowdown and hanging of Firefox is mainly why I switched over (in MS Windows) to using Chrome instead of FF. FF would simply hang or quit responding. Chrome doesn't do that.
I kept upgrading all the way to FF v11 -- and the problems still did not go away.
Try using another Browser and see if the problems remain.
Ubuntu 16.04 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
Will not respond to PM requests for support -- use the forums.
