I think I've had enough dealing with firefox, I'd rather have a browser with 64 bit
just do a factory reset of firefox. nothing is gonna compare to mozilla. :)
Try Google Ultron.

I recommend you get Adblock Edge and Classic Theme Restorer (Its what I use to get square tabs).You should probably check what flags you can edit to speed it up.
