Firefox still doesn't have vertical tabs which I've found really useful for my workflow right now, so I use a fork called Pulse. Don't want to use any extensions for it when Pulse and other forks do it natively.
Probably, but between the disabling of userChrome.css (even if you can enable it via about:config) and a possible conflict between other addons I use, I'm comfy with my Pulse setup.
I explain it in another comment, tl;dr: have to edit userChrome.css to give it a more streamlined look (and Mozilla calls that feature "legacy" in about:config since v69 which kinda worries me about that feature's removal) and I'm not sure if some extensions might conflict (Would it have issues with Simple Tab Groups). Pulse does it natively and really well, so I'm happy with it.
I used Tree Style Tab but I didn't like having to change the userChrome.css to make it streamlined (i.e. hiding the tab bar), while Pulse does it natively and really well. I do have an extension for tab groups that imitates Vivaldi's tab workspaces though, not sure if those will conflict. (If you're curious, it's called Simple Tab Groups.)
Edit: There's also the issue of Mozilla calling the editable userChrome.css a legacy feature, which kinda worries me about its possible removal. Pulse having vertical tabs as a native feature skips that.
Orion apparently allows extensions like uBlock Origin. Not sure if anyone has put it to the test but superficially, its there. Hard to tell where Orion ends and uBlock Origin begins since it seems adept at dealing with fingerprinting and other niceties by itself
You can't download and run code on iOS, which is pretty much the definition of an extension. You could ship some extensions "with" your browser, but at that point they're just a feature. iOS has adblocking addons at the system level though, doesn't it?
Ya, the extension aspects of iOS are a headache in terms of understanding everything. I look forward to liberalisation of 3rd party browsers allowed and any consequent innovation on mobile browsing.
Why are you gaslighting so hard. Just lookup what adware is. It has literally preinstalled crypto marketing widget that you need to disable or smth and also provide a opt-in ads for crypto solution that has opt-out "Gift the tokens to the page that has no wallet"
When one makes a claim like that when nothing indicated such things, its accepted in the community of behavioral analysis that it was a projection. Bravephobes love making shit up Lol
