I 'upgraded' to FF 58 last evening. It is slow and some of my sites don't work properly. I want to go back to FF 57 which was working OK. How can I do this?

Thanks. I completed all that and there is some improvement except for my webmail page not rendering properly. I tried starting without addons and it was OK. Going through the installed addons one by one I found it was the Zoom for Firefox extension causing the problem.

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do : https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Reinstall with Current Release Firefox 57.0.2 with a Full Version Installer https://www.mozilla.org/firefox/all/

Make sure : go to the Firefox 3 Bar Menu --> Options --> Privacy & Security panel and under Permissions check the setting to Prevent Accessibility Services from accessing your browser.

If high cpu usage : Go the 3 Bar Menu then Options --> General --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 1 = No Multiprocessor = slow again. Try 2 Restart Firefox after making these changes please.


Please let us know if this solved your issue or if need further assistance.
