You can turn it off by going to ''about:config'' and switching ''browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar'' to '''false'''.

OK I will try that. What about the searches that I try to type into the central search bar which are typed out in the address bar at the top - why is that happening and can I switch it off?

You can use an add-on theme to fix the tab bar color issue, or you can roll back the layout change using a temporary preference. You don't need both of these. '''''Theme''''' If you prefer the colors of the "Default" theme from Firefox 57-88, someone created an add-on theme that emulates it. You can give it a try here: https://addons.mozilla.org/firefox/addon/photon-colors/ <img src="https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2021-06-02-17-19-21-6cf38c.png"> If that color doesn't suit you, the Firefox Color extension lets you create your own theme: https://addons.mozilla.org/firefox/addon/firefox-color/ ---- '''''Tab Shape / Separation''''' I can give you a quick short-term workaround, but a more durable solution will require more work. '''Temporary Fix''' For testing purposes, there is a preference to switch the tab bar and address bar between new style and old style. This is not expected to continue in Firefox 90, but maybe you want to use it for now. (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 style) and '''false''' (old style) '''Longer Term Community Workaround''' This involves setting up a userChrome.css file. I have a rules builder that will get more features throughout the month. By the time the above preference is removed, it should be mature.
