I downloaded the new Ffox. It was OK for 3days until Windows updated. Ffox then performed worse than it ever has. I downloaded Ffox again, no chg.

Has anyone less encountered this? I use only the basic Firefox. All aspects of Firefox are now incredibly slow. All sites are slow, scrolling is slow. It is so slow that I have gone back to using Chrome. Chrome is working fine so I know it's not my machine. The startup time graph has skyrocketed the last few days.

In Help > Trouble shooting I found

Accessibility Activated true Prevent Accessibility 1 Accessible Handler Used true Accessibility Instantiator

I went to options > privacy and security and found that the box for Prevent accessibility services from accessing your browse under Permissions was unchecked. I checked the box and restarted FireFox. It now works fine. Thanks.

hi, thanks for reporting this. could you go to the firefox menu ≡ > help ? > troubleshooting information page and take a look in the Accessibility section if accessibility is set to "true" there.

if yes, can you please copy & paste this whole section into a reply in the forum and see if the following fixes the performance problem: go to the firefox menu ≡ > options > privacy & security panel and under permissions check the setting to prevent accessibility services from accessing your browser.
