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.

old [Tile Tabs]better

People are giving this a crappy review because of limitations that are outside of the author's control, so they're barking up the wrong tree.

It's not perfect, but this is one possible workaround, and I'm glad it exists.

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.

This add on had been great but since the upgrade it's not working the same :( still giving it 4 stars and hoping the issue get fixed ASAP!

Two or more windows are devided precisely on screen automatically.

So It is stable and easy to my eyes preferably. ^^;

It is working very well in my fox (Firefox Quantum 57.0.3. (64-bit)).

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.

Doesn't work well in Kubunu 16.04 LTS (most recent LTS) - windows are overlapping, not really usable.

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.

KEYBOARD SHORTCUT NEEDED BACK!

Great addon. Since the latest version, it unfortunately does not allow to use shortcut! I only used F12 as a shortcut to split view. Without keyboard shortcut, I barely ever use this addon anymore. Will definitely put 5 stars as soon as the keyboard shortcut is back in the app!

Thanks for the amazing work.

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.

Okay, I understand the changes. I still give it one star. I would give a half a star if possible. This add-on sucks. Opening multiple windows is NOT a good solution for the loss of the ability to actually tile tabs.
I give Firefox "Quantum" one-half star as well. Who gives a rip what Google and Chrome do? I use Firefox because I don't like Chrome. Mozilla; why emulate a browser you are competing with? Shame on you. Regain your honor and independent identity. Either put the silly thing back the way it was or fix the currently crummy product. When you want to open a new tab, please don't open a new separate window.

Es genial!!!!
