But the company took it upon themselves and tried their best to bust this notion of mine. Unfortunately, they seemed to have passed with flying colors, with the release of version 91. Even if it had a few loyal fans remaining, they would have surely jumped ships over to other Chromium-based browsers by now. Granted, whenever a new UI update is released, users tend to have mixed feelings about that. But this time, they all are on the same and there isn’t an iota of doubt that the latest UI tweak is a complete failure. The latest Proton UI has completely ruined the interface with unnecessary spacing and padding across the tabs, bookmark bar, context and pull-down menus, among others. And the icing on the cake? They have even removed the tab separator icons. As a result, all the opened tabs look like they are now merged into one another!

At the very least, they should have first rolled out these changes to the beta testers or the developer preview builds, but no, they straightaway decided to let the stable users adapt to this UI change, whether the users like it or not. There are a couple of Reddit forums where a plethora of complaints are already lined up since the past couple of months. So if you want to know what all is wrong with this new update, just have a sneak peek over to both these forums. Anyways, all the users are having the same query in mind- how to roll back this change? Well, there’s some good news and some bad ones. The bad news is that there’s no official fix for this as such, and it doesn’t look like Mozilla is in any mood to release one either. The good news is that there are a couple of workarounds that have been known to spell out success for many users. But again, the bad news is that these workarounds are a little bit technical (though I have simplified this procedure with all the necessary screenshots) and might not be everyone’s cup of tea and that is completely understandable. So it completely boils down to an individual’s preference and if you are ready to try it out, then let’s get going. Follow along for the steps to disable the Proton UI and decrease the tab and bookmark spacing/padding in the Firefox browser.

How to Decrease Tab Spacing/Padding in Firefox

So this was the first method to disable the Proton UI and decrease the tab and bookmark spacing/padding in the Firefox browser. Let’s now make you aware of the second approach to carry out the same task.

How to Go Back from Proton UI to Photon UI in Firefox v91

Many are calling Proton one of the biggest UI failures in a long time. If you also echo this thought and wish to revert to the older Photon UI, then there’s a script for that as well. However, if the above CSS file worked well and good, then there’s no need as such to try out this CSS tweak. However, if you still wish to give it a try, then please delete the chrome folder from the above tweak first, otherwise, it will conflict with the new one. Once that is done, you may proceed with the below steps:

Concluding Remarks

That’s it. These were the steps to disable the Proton UI and decrease the tab and bookmark spacing/padding in the Firefox browser. Many of you would echo this thought that why would a user have to make such technical tweaks to a browser for something that they didn’t ask for in the first place. Well, around four months have passed since this fiasco and there have been no hints of a UI rollback from Mozilla. So as of now, these tweaks of adding a new userChrome.css scripts seem to be the best bet forward. In this regard, we have shared two different methods. Do let us know in the comments section if you have any queries concerning any of these two approaches.
