edit: Thanks to the replies, I figured 1) You can put the address bar at the bottom of screen 2) You can swipe on address bar to traverse through the tabs and 3) You can change the tab viewer layout to list view.
(Still, I wished there was an option to list tabs on the bottom like the way Chrome does in on Android.)
I have to go through and close each tab one by one first. It's driving me up the wall.
Slightly quicker than doing them one by one.
But truly, if this is the biggest issue I have with it, that's pretty good. It just makes me actively irritated every time I use it.
When I was searching around trying to find a resolution with this problem, I found numerous comments saying that Mozilla does not intend to change this behavior in the future. That made me a little mad.
Update: vorticalbox gave me the solution to this in another comment. I take this all back.
My only issue with Firefox is the lack of easy access multiple profiles.
I can live with that, although I wish I could pay to get that fixed.
You can toggle "open tabs" to close all your tabs
Doesn't that delete all browsing data, though? That's not what I want. I admit that I haven't dared to touch it because I assumed it deleted all browsing data. I'd be thrilled to be mistaken about this.
Open tabs, browse history, cookies, cache, site permissions and downloads.
You can enabled as many as you like.
Just having "open tabs" ticked will only close tabs and nothing else which is what I use
In my web searching to find a resolution to this problem, I didn't find a single mention of this. Oh, web, you have failed me again!
