@zenixco I do have some extensions but i have tried turning them all off. I have tried a clean install by removing everything and installing etc. All had the same problems once i started to have a lot of tabs. Only thing that fixed it was going back to v77. I am now trying the latest v84, still slower than v77 but definitely better than what i used to get on v78,79,80 etc.
I am going to stick with it and see if i can handle it because i do want the newer versions for security reasons.
