i was using the version for firefox 56 and was forced now to update firefox. The newest version that is compatible now is just useless and annoying ...
Cons: -used to be simple and just tile as many tabs as it was selected in the way you wanted
-used to be simple and you could just open new tabs with Shift + arrow in the direction you wanted
-used to have only one menubar for all
-now you have a gazillion firefox windows with extra bar on top
-sometimes it works sometimes you can just click it 10 times and nothing happens
Pros: -none so far !

Terrible. At least give us the option to revert back to the old tiles page otherwise you're going to have a lot of people installing older versions of Firefox for this functionality.

I know it's problem of web extensions but still give you one star.

Not a real Splitter :(

This does not work at all.

My setup:
- Mac OS Sierra
- Firefox Dev Edition
- AddOns that may interfere: Simple Tab Groups
- 2 Monitors (Firefox running on secondary monitor)
- Several tabs open (but only want to use tile tabs for 2-3 tabs).

What happens when I click on new tile tab layout:
- Moves two random tabs to primary monitor on two new opened windows side by side
- The windows are not tied together, so when I resize or move one, nothing happens to the other
- I canno make this work on secondary monitor.
- I don't want the tiles to be in new windows but rather in a new tab.

I could rate this lower, but 1 is the worst.

I feel bad for giving this a one star, the previous version was amazing. This one is horrible. Pretending browser tiles are "fine" (they aren't), there's no good option for deciding what tabs get moved next to each other. If you accidentally close a tile, it disappears and cannot even be pulled up via closed tabs list. I just had to remove this add-on, it just sucks so bad now.

The previous version is far better, so sad. I realy tried, but i can't organize tabs as well like before.

совсем не то что старый tile tabs. вместе с treestyle tab полностью бесполезен.

I want the old side by side Tabs feature. This version is crap

This extension is impossible, I cant arrange tabs, the only thing this plugin does is generate new windows that mess with everything.

This is as bad as it gets...Doesn't even come close to being a helpfull tool. The old Tile Tabs where 100x times better. To bad the old one isn¨t supported in the latest firefox version.

I can't have two tabs side by side.

I'm not a fan of the multiple windows approach. That's why we have TABS!
I may re-install when it works properly the way the old (non WE) version did, in tabs.

Please find a way to bring back Version 14.12 Released Aug. 15, 2017. This new Tabs WE is not nearly as awesome as the previous. Please, i rely on the version at work daily. We have a lot of worried Co Worker :(

Pffff, anyone can open two separate Firefox windows, there was and is no need for an add on for that. What was wrong with the old Tile Tabs, it was the most handy add on for me. Hey old Tile Tabs guys please do something. Firefox is not complete without you.

I understand the limitations imposed by the new Firefox, and I wish others would understand what they are rating before throwing out 1 star reviews.

I have to however rate it at 1 star. At this point I think you are doing all you can, by moving a tab into a new window. My issue is that your methodology is highly flawed for any reasonable work flow or use case. You should really simplify the operation. Just give the option to tile the first tab as horizontal or vertical. From there you can keep adding them to the screen.
An example.
Tab1->Vertical
[Main][Tab1]
Tab2->Horizontal
[Main][Tab1]
[++Tab2++]
Etc.. Or you could launch the tile by direction.
M(Left)->1 | 1(Up)->2 | M(Up)->3 | 2(Right)->4 = Error = Slot Full
[2][3]
[1][M]
If you can't control where the windows go or move them after launch, then just cut out all this broken stuff and branch 1 window left or right or up or down. I can all but guarantee that the most used feature is moving 1 tab side by side for a comparison. When the new API gets more mature go back and add features, but for now make it work in a logical way.

I think the thing that does it in for me is that I say I want two tiles, and the add-on creates three. Just create 1 new window with the tab I have selected. This lets you control what 2 tabs you want because you can switch around in the main window.

i like the old version. this is just to complicated and i don't understand why it's being split from windows instead inside the window itself. it's stupid. i don't want this extension no more.

Quantumから全く別物になってしまった、新firefoxのアプリケーションの構造上の問題だからといってここまで改変されるとちょっとショック...残念

J'aurais mis 5 à l'ancienne version ! Tile Tabs...
L'affichage de deux onglets contigus partageant l'écran d'un double clic me manque énormément. (l'anglais n'est pas mon fort !)
