Revert curved tabs to square tabs after new update (89.0)

I recently updated Firefox to version 89.0 which made my tabs curved rather than square/blocky. Is there any method to revert the look of my tabs? This is strictly for aesthetic purposes.

Chosen solution

Yes and No. There is no built-in setting related to changing the shape of tabs in the context of the new UI, but I will mention two other options:

Community Workaround

This involves setting up a userChrome.css file. Does that sound familiar? It's an option style sheet you can create to modify Firefox's user interface. I have a rules builder that can create a rule to square off the tabs, reconnect them, and optionally add more definition to background tabs. There also are very comprehensive overhauls created by other users on the FirefoxCSS subreddit. If you are curious:

Temporary Rollback

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 if you're having a hard time with the new UI.

(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)

Hi,

We bring a modernized and differentiated look to tabs since Firefox 89 in order to create a signature Firefox look and experience. This major redesign will help us enable more use cases and features in the future.

The link would go into a userChrome.css file. See: https://www.userchrome.org/how-create-userchrome-css.html

Probably, although I don't have any. You could inquire on r/FirefoxCSS (https://www.reddit.com/r/FirefoxCSS/)
