It's one of the reasons I gave up on Firefox. Mozilla have no incentive to improve Firefox and can afford to keep running it into the ground knowing Google has to foot the bill for them to not get hit with the monopoly hammer by the US and EU governments.
I agree that it sucks. But does it really suck more than the alternative (Blink monopoly and terrible vertical tabs implementations)?. No way. I made most of these changes years ago and have just migrated my Firefox profiles directory since.
Here's my aproximate browser history since I started using the internet. IE(2002) -> Firefox(2004) -> Opera(2008) -> Firefox(2011) -> Chrome(2015-present) -> Brave (probably in the near future)
