re instal previous version of Firefox

Hi Ray, what isn't working for you in Firefox 159? Some users do not like the "Nova" design update with its more rounded shapes. If that is your main issue, there is a temporary method to roll back the "Nova" design update to the previous appearance. I don't know how long this will be available. I will also provide a link to the "downgrade" article, but I think you'll find the toggling method much simpler: (1) Downgrade option See: [[Install an older version of Firefox]] (2) Toggling a hidden setting (a) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button accepting the risk. ''More info on about:config:'' [[Configuration Editor for Firefox]]. ''The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.'' (b) In the search box in the page, type or paste '''browser.nova.enabled''' and pause while the list is filtered (c) Double-click the preference to switch the value from true to false - several seconds may pass before this takes effect (see attached image for the difference)
