This extension is excellent although no longer being supported. I have split a single tab into 3, divided viewports. Perhaps you can do more? I did end up having to use the also-fine Stylish addon in order to override the dark background color this addon uses on pages which lack their own background color style. So thank goodness for that one as well.

Eliminates functionality of all other plugins. I LOVE that this works EXACTLY how I'd want it to. But it works in it's own space in the browser which does not allow communication with any other plugins.

Unfortunately, I can't use this in that state. But I understand that this is probably a technical challenge that might bump up against limitations imposed by the browser itself.

I appreciate the effort, though. :)

5 star extension
Gemini and ChatGPT work great. Grok does not.

Cool add-on, but...
Other extensions for the project don't work.
After arranging tabs side by side, you have to restart/re-enable uBlock, then it works on the merged tabs, but others don't (e.g., Don't care about cookies).
It would also be useful to have tab scrolling synchronization, similar to Tile Tabs WE.

Seit Tagen suche ich eine Add-on welches dem Splittscreen vom Edge Browser gleich kommt und hier ist es. Keine Probleme beim anzeigen der Fenster und alles so wie ich es mir wünsche.
Vielen Dank für die Arbeit!

Merci pour ce plugin bien utile !

Does its job to a T.

I love this so much! It is even comparable with Edge split screen if not better than. This add-on can split 3 screens or 4 screens if needed. I am really grateful because I am an Edge user moving back to Firefox. I miss the split screen feature and then this add-on has make a good substitution.

A very useful and excellent extension.

I liked it! Thanks!

I have been using the dead project "Side View" by Mozila. And this is nice!

I have a few suggestions for Multi Split View:

- Easy change the side of the websites (move the website opened in the left side to the right side)
- Easy way to change one of the websites (instead of change the url, just click in on the tab)
- Fix one side site (just as Side View) - One side site is fixed and when you click in other tab, the other side site change.
- Naming workspace is nice, but i think this consume part of my screen. Maybe thinks in a new way to do it.
- Select two tabs, click with the right bottom, and select to create a work space (instead of clicke in the addon on my bar)
- New icon, i think this colors are ugly in my bar (lol).

the single tab mode breaks some of the pages - regardless of ad-block. the tiling block is no different than popping two browser instances side by side. please consider changing that hideous icon into something less flamboyant.

I like it. I miss so badly this configuration from Zen Browser in vanilla firefox.

This addon can add several tabs into one. Mosaic view sucks, but the Iframes is quite cool. I will give 5 stars when other addons work in the Iframe view, not just for adblock, but for password manager, mouse gestures, etc
