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.

Hello, Here the information : Accessibility Activated true Prevent Accessibility 0 Accessible Handler Used true Accessibility Instantiator UNKNOWN|

I flag the setting "prevent accessibility services from accessing your browser"

I will test some days and come back for a status. So I'll quit Chrome for some days :-)

Best regards

For information The new values

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

thanks for reporting back, i'd expect your firefox may get a bit of a speed boost now :))

Hi, Here my returns after a fee weeks of tests with the release of Firefox. The set of "prevent accessibility services from accessing your browser" have solved my initial issue. However Firefox remains in my test conditions lower in performance compared to Chrome. But other elements force in to return to Chrome. An example : During a PayPal transaction I got a "time out" Same time, same site and transaction, no problem with Chrome.

Regards

Performance in Chrome and FF are the same on my computer. Human can't perceive ns difference that are to small to notice-that is a myth that people like to use and has been debunked already. What would be different is if this was a clean or upgrade install that would be where to start.
