It offers a new way to organize your Firefox, like a Desktop.
Would be nice to set different colors to groups. As a feature ;-)

Excellent!

This is a good panoramic group tab. But this needs to be fixed, some icons on the extension toolbar can't change color when in dark mode, there is difficulty in saving group names and scaling groups. And I think you need to develop it, so that when the browser is closed and reopened the tab groups are still there like in other browsers, so that makes this extension more impressive. I hope you can fix it soon. Best regard.

Functionality wise I love this extension and wish I could keep using it but unfortunately performance wise I've determined it to be the culprit behind Firefox having a CPU usage upwards of 50% on an i5-9600K @ 5.0GHz with under a dozen tabs open. All of the tabs were extremely light pages such as wiki or github pages containing basically nothing but text and hyperlinks. I've never seen Firefox go above 10-15% CPU usage even with close to 100 tabs open across multiple windows on multiple monitors with stuff like YouTube and 3D web apps going, especially since hardware acceleration was added, but this extension bumped the Firefox task to 25-35% CPU usage as well as bumping Firefox's WebExtension task all the way to 15-25% for a total averaging 40-60% CPU usage. Immediately upon disabling the extension Firefox/WebExtension usage dropped down to normal levels. I ended up switching to the original Panorama View (which this extension is a fork of) and with all the same tabs open Firefox hasn't gone higher than 1% CPU usage and WebExtension hasn't gone above 0.2% so I'm not really sure what's going on with this extension but if you're using it I'd advise checking out whatever system monitor you use.

Terrible ext from 90's
Just see like it work in opera!!!!!!!!!!

User-friendly and helpful

No idea how to get it to work. A manual perhaps?

I absolutely love this add-on, unfortunately a recent firefox update has made it so enabling this or similar extensions will make it so tabs can no longer be moved around. I hope this one issue is resolved quickly and I can continue using this great add-on.

works pretty good, but when i updated to sequoia all of my groups were deleted and only my pinned tabs remain. odd since i've updated to sonoma and that didn't happen.

good old panorama substitute. works better/smooth than other panorama-like addons, despite being so old.

Indispensable ! Une mise à jour pour enlever le bouton + serait chouette.
