Develop extensions, it's important because Firefox doesn't have extension grouping, hopefully it will be lighter and work faster, without crashes, and new features, thanks.

it's nowhere near perfect, but it is far better than the few other extensions for this kind of workflow. if you work on it a bit you can get it to do what you want.

DO NOT DOWNLOAD. WORTHLESS EXTENSION ONLY RUINS YOUR TABS. Developer: are you dumb? Why did you create this worthless extension? Do you know how much research I lost in trying to use your stupid extension?

This add-on simply become must have add-on for me.

Not sure why so many reviews are saying this is hard to use. I found it easy and simple to setup and start using.

Not simple.

As other 1-star reviews have stated, this app is counter-intuitive and not very helpful. If you are looking for something like Chrome's tab groups, this isn't it.

Spent an hour or two trying to figure this out. It ain't simple. Nearly lost 30 tabs I had open. Add-on had hidden them. Once I found them I had to move each tab individually (never heard of select all?) to get them in one window/group before I was confident I could delete this add-on. Instead of saving me time, it's wasted much of the morning.

It's one of the best extensions for managing your tabs and multi browsing Experience if you surf the web searching for multiple stuff and need a safe way to save them and manage them this is the best tool you can use, I use it every single time I serve the web it can manage tabs as groups.

I am used to have "Tab Groups" on all used browsers but FF does not offer this natively so I installed this Add-On.

It does not work properly. When I move a tab to a group sometimes it does not disappear.

I do not like the approach at all! I want to have it like on Chrome and EDGE. Maybe the FF API does not offer that kind of integration?

For me this Add-On is a workaround until FF developers will add native support for it.

So for the moment I'll try to avoid FF as often I can and switch to Chrome and EDGE.

2024-10-04 Update my review a bit and increased to 4 stars since it is useful.

After using this for some months every 3 weeks all groups are empty, loosing time to recreate them. FIX IT

I learned how to add tabs to a group but opening the groups was confusing to me. I found no way to open groups in their own windows. It uses hidden tabs in which you switch between your group and your normal casual browsing and it is not intuitive. Adding tabs to a group was awkward because you can't select your tabs among the already opened; I had the close the tabs I did not want grouped. Simple Tab Groups comes with many features that were not much useful and the core function of it is much to be desired. There is no reason to use this because you can just create a folder and store your tabs in there to simultaneously open all those tabs later from your bookmarks.

Ridiculously complicated, not "Simple" at all. When I hear "Simple Tab Groups" I think of something my grandmother can figure out.

This took way to long for me to figure out how it works, only then did I realize it was so fiddly.

Like most of the low ratings I was hoping for something like how edge or any of the chromium browsers handle tab groupings.

In the sea of over complicated tab managers, this was a exactly what I wanted. Its simple and it works

グループ分けが非常に便利ですが、タブを閉じた時複数のタブが残っているのに稀に現在のグループから別のグループに移動してしまうバグが出る場合が有る。

LOVE this extension!
Yup, it's simple, and it's great for keeping organized!

I have a group for "general", one for school, and one each for whatever games I might be into. (Right now Satisfactory and BattleBit.)
Super amazingly convenient to have these tab groups ready to go. They are much more flexible and easy to adjust than a bookmarks folder. Just right click a tab and send it to a group, or use the pop-up, or the manager.

You can even choose to hibernate tabs/groups (or not), but they'll still be "open" for later use. You can have a tab loaded and running some demanding applet, but still get it out of the tab bar so you can focus on something else momentarily. It's amazing.

Some of these functions are available in other extensions like Sidebery, but again I like this one for the Simple aspect. I use this in tandem with Tab Center Reborn for a (again, simple) vertical tabs sidebar, and now my toolkit of tab management is versatile yet lightweight, and still in dark mode!

I nearly forgot that sadly I'm here to comment on a pet peeve. The tab overflow icon, that little arrow managed by the about:config preference browser.tabs.tabmanager.enabled, is for some reason inescapable when using this extension, unless you are in the "other tabs" misc group which defeats the purpose.
Something to do with the behavior of the arrow: it is only supposed to appear if you have many tabs, but with this extension I can close all my tabs and just having the tab groups active even when empty shows the arrow. Small irk, very silly for me to be frustrated by, but there you go.
I don't know if I could possibly work around this using the extension's settings, I haven't tried, and I don't know if it could be patched by the extension dev to behave differently. So it's definitely still a 5 star extension. I love all the other stuff it has going for it.

Thanks Drive4ik for the great extension!!

BTW Mr. Dev, if you're reading, any chance for a feature like "automatically discard previous group when switching groups"? Or maybe a button that will switch to a group and discard other groups at the same time? My machine is not super strong and I run multiple apps at once, so it's usually best for me to hibernate inactive groups, and it's tedious to right click -> "discard other groups" all the time. Thanks!
