It's hidden behind a right click menu. So it's a muscle memory friendly change. I don't remember the url bar change to be too disorienting either.
It's not really. Now when you right click (long press) to open a link on a new tab it opens it in the same tab group as your tab. If you then use the button at the top to switch tabs (how it worked before), you are now switching tab groups. To switch tabs in your tab group, you have to do it at the bottom.
This should be possible on Firefox too: https://developer.mozilla.org/en-US/docs/Tools/Remote_Debugg...
It's slow as molasses and loses UI events. I had auto-update turned off so I didn't use the new Firefox for Android until recently, and now I sincerely regret I updated it.
They also did something silly with trying to match your tap to closest link even if your tap falls squarely outside of the link's activation area. It's super annoying on sites with small text, like HN.
On the flip side, the UI being garbage made me stop browsing HN on my phone, so overall, perhaps that's an improvement in terms of my productivity.
Same with Firefox on Desktop, for that matter.
I'm on Waterfox Classic on desktop, but that's probably not gonna last forever either. And when that eventually drops support, I'll just stay on the last version until some browser vendor brings multi row tabs back. On mobile, I visit maybe five websites, and the three most common ones don't have ads, so I'm happy with my pinned old Firefox Beta version. And no matter what happens, I'm not upgrading to current Firefox on Android - well, unless the thing that happens is they take that abomination of a UI back behind the shed and put it out of its misery...
The way I look at it, it's unfortunate that the one single browser actually worth using sadly no longer gets security updates. That sucks for me, but I'm also not gonna stop using the browser.
