Firefox running incredibly slow and is unusable.

Posted

I updated to Firefox57 and the web browser in now so slow it is unusable. I have tried refreshing and it did not help at all. Neither did safe mode. I honestly don't know what else to try. It took me five minutes to type this message in Firefox. Please help thank you.

thank you - for the record, the paste was https://pastebin.mozilla.org/9072981

can you please test if the following steps can fix the performance issue you're seeing & let us know how this goes?: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named accessibility.force_disabled. double-click it, change its value to 1 and restart firefox once.

thanks

hi ncl1701, 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!

I tried accessibility.force_disabled=1 and restarted again in safe mode. The responsiveness improved a bit, but it's still hideously unusable. Since Firefox is not using much CPU or memory I think that some thread in the process is blocking out the UI thread by holding onto a lock. Basic GUI widgets are not responding to simple events by highlight, etc.; the scroll wheel is ignored, etc.

Unfortunately, the offending thread is doing this repeatedly and for fairly long periods; the GUI thread is only getting very short windows of time to perform user interaction which makes it virtually useless as a browser.
