Hi This is just a comment i am not very happy with the new rounding of the horizontal tabs as mentioned in the release notes of release 145 beta. I personally think its over rounded and makes it look to much like you are trying to copy a style which i personally don't prefer. I find that over rounding can make buttons look worse combined with confusion over hitboxes and where they start and stop because they no longer line up visually.
Also i reorganise my tabs a lot to have them in a certain order which now seems to conflict way more with the tab organising system is it possible to disable the whole system as i don't care about it i will split into multiple windows if i want to organise?
Also another comment the settings menu is truly terrible to navigate its all the way to the left instead of centered which is weird and also some menu items are really short but others are multiple a4 paper long. Maybe reorganise and center it for better readability
I also tried looking in the about:config if i could change the style back but could find no such option.

To make tab corners square:
Put this code into your userChrome.css file:
:root {
--tab-border-radius: 0px !important;
}
If you're not familiar with using CSS, see userChrome.css for Customizing Firefox.
To disable tab groups:
Type about:config in the address bar > press Enter
- click 'Accept the risk and continue' if that appears
- search for browser.tabs.groups.enabled > change the value to false
