My Quantum update only works after a refresh, the moment I start loading pages, it slows down and then freezes on a page - the only way out is to "end-task"

Windows 7, 64 bit -

After a refresh Quantum response degrades as pages are loaded. After loading say "The Wall St Journal" clicking to get a new tab takes a second, similarly scrolling the side scroll won't respond right a way. It takes a second. When it does move it will stop following the mouse, then when you stop the mouse it will jump to where the mouse is. Things get progressively slower and jumpier until it either blows up itself and gives a message (that the failure has been reported) or a page freezes and you have to CNTRL_ALT_DEL out of it and end the task.

How do you fix this?

thanks a lot, it would also be interesting if you could post the content of the accessibility section of your about:support page still.

then please see if the following change can alleviate the performance problem and report back about this?: go to the firefox menu ≡ > options > privacy & security panel and under permissions check the setting to prevent accessibility services from accessing your browser.

hi proximo, thanks for reporting this. could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum? (or if it's to long through a site like https://pastebin.mozilla.org/)

this might give us a clue what is going on. thank you!
