How can I revert back to Firefox version 88. I have used Firefox for many years but do not like the latest automatic update?

Hi caharvey, old versions of Firefox are always available, but not recommended. There's more info in this article: Install an older version of Firefox.

It would be helpful to know more about your individual pain points with Firefox 89 in order to know whether we can suggest a workaround.

I will mention that there is a temporary preference in Firefox 89 to revert most of the tab bar and address bar changes. However, since this was retained just for testing, it might be glitchy.

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste browser.proton.enabled and pause while the list is filtered

(3) Double-click the preference to switch between true (new UI) and false (old UI)
