Many years ago they had an offical extension called "Tab Center", it had been in "labs" for some time. When it finished testing (it worked well), Mozilla decided to drop it instead of deploying it in Firefox. It wasn't even in low priority.
It took them many years and they finally implemented vertical tabs in 2024.
Pretty accurate except for "we must focus on the browser", I've never seen/heard them doing that.
I still remember when they cancelled vertical tabs after successful testing.
No offense. But I'm completely going to offend you.

YouTube isn’t a necessity — and neither is the internet, really. We don’t need them to survive. That said, I do enjoy YouTube as a form of entertainment. I’ve tried alternatives like NewPipe and Invidious, but none of them work as smoothly as YouTube with ad blockers.
I would suggest using PieFed as well, so we are free from software developed by tankies.
Sorry for AI but I couldn't find it by just googling:
Yes, Firefox did have an in-house developed "Tab Center" — it was an experimental feature created by Mozilla as part of their Test Pilot programme around 2016–2017.
🧪 Mozilla's Original "Tab Center" Name: Tab Center
Status: Experimental Test Pilot feature (now discontinued)
Timeframe: Circa 2016–2017
Purpose: To explore the usability of vertical tabs on the left side of the browser, instead of the traditional horizontal layout.
🔍 Key Features Displayed open tabs vertically in a sidebar.
Showed a more spacious, scrollable list of tabs.
Included favicons and tab titles — easier to manage lots of tabs.
Supported mouse gestures like tab pinning and closing.
Looked and felt very similar to Edge’s modern vertical tabs.
