seems like a onetab open source alternative

Love the addon. I've tried a lot of others and they were too buggy or unintuitive. This is simple and effective and doesn't use RAM. Love it. Cheers!

I really like this add-on. It isn't the slickest, but it is the most useful tabs add-on I've tried. I really like that it tracks changes to an active session. It is exactly what I've been looking for. Hope it catches on so the development continues.

This is a very good and helpful add-on,here's a five-star review so you keep good work going,Also I have a suggestion. I would like to see a feature that lets you drag any tab or tabs to a specific session.Although I know that you can add it by right-clicking and choose what session you want.It'll be awesome.Otherwise the add-on does what it should do and is very helpful,keep the good work!

Edit after developer response: I just noticed that if I want to add a single tab to a new session I can't,It has to be an already saved session,Can you add this option in the right-clicking menu when you right click a tab?,and also thanks for your response. If you can't add dragging tabs feature it's not a problem,But consider adding the option I wrote earlier in this edit if you can.Thanks!

It works just as expected, it hides my tabs just like the feature in Edge!

Отличное приложение. Сделайте русификацию (на русском языке)

Simple, easy and fast! I totally love it, exactly what I needed!

Excellent!

Just what I was looking for (the same tab feature found in Microsoft Edge) !

:D

Its great to use to save memory and increase performance by closing unwanted tabs and accessing it again when needed.

Thank you for this add-on! One of the best features from Edge brought over to my favorite Firefox browser.

This addon keeps me from going to edge.

I love that you can name your sessions, its unbelievably helpful as i'm trying to keep track of tons and tons of tabs.

"If you ever choose to uninstall this addon your sessions will be kept in your bookmarks" is also an incredibly helpful feature.

You have seriously saved me lots of time and will save me more in the future as I continue to use this extension, be proud dev!

The only issue I've found is that if you remove a session while you have the sidebar open in two windows, the session will disappear from the first window but not the second in the ui. The bookmarks folder that hold the session is still deleted, its just that the UI of the second window sidebar hasn't refreshed yet. Maybe you could make the sidebar in every window refresh when you delete a session in one window? Minor issue anyways.

Thanks! The ability to switch sessions like this is really perfect for me!

Good extension, but active sessions from last update don't keep tabs that I opened by myself. I used this algorithm before:
Working in a window - Set tabs aside for a while - Continue work from where it stopped

Now I can't set all tabs aside, so could you add tracking for all tabs in a window? Or maybe you can add an option to turn active-sessions-feature off? Anyway, thanks for development
