[Update: just noticed that Simple Tab Groups (STG) was updated today - to v2.4.8. This is according to FF\Recent Updates, which also states "Sorry, but there was an error loading the release notes". Might any of these factors be something to do with my total loss of all tabs and groups!?!? Seems I'm having Certificate issues in FF now also. Concidence? Mmh]

OK. In principle this add-on is exactly what's required: and easy way to switch between groups of tabs.

By this I mean it should be like a "bookmarking plus" process, whereby a group of tabs is opened, new tabs become part of that group, and all tabs are auto-saved immediately as such. In this way, the tab "Group" is kind of similar in concept to a bookmark "Folder" except the latter is wholly maintained manually (time consuming, error prone, but safe!).

Managing tabs in groups (Moving etc.) is then required, as is naming the groups. This is achieved for the most part (but could be a bit more streamlined re the deepening menus!?).

This system is good, and users - including me - are becoming highly reliant on this add-on for everyday use. Great!

But when a user looses 100's of tabs that were in numerous groups (yep - like me!), it means there's something fundamentally wrong with the design.

I am aware of the Firefox bugs mentioned in various places, but this add-on needs a solid, fully-tested means of automatically backing up groups of tabs. In my case, Win10 glitched and put apps in a semi-disabled state, so MS have caused this, but still...

Having no obvious means to recover tabs is a REAL pain. I do have a manual backup of 2-3 weeks ago, but that's way out of date even after 1 hour of serious browsing, working, researching etc. etc.).

IMO, I don't see the need for 'live' or always open tabs when switching groups. Keep it simple I say. I group tabs (or did before it all went awol) by 'project' and by 'work mode' (e.g. "MX5 rebuild" and "Web Training"
etc.)

So my advice is to set a clear requirement spec and stick to it! Get it working and really reliable (users will help!!). Then... see what users want. A lot of good work has gone into this Addon and it's potentially brilliant, but it's popularity will turn to hatred with no crash recovery options. Crashes happen (MS!) and are OK actually (what!?!) as long as they're not too often (a sad state of current day software running under Windows, but that's modern life for ya!).

I hope the developer can assist me (and others!) and I can recover my groups, but otherwise I can't afford another "total loss" and will have to ditch this add-on :(

Best wishes peeps //L

Добрый день! Все хорошо, только есть один момент. Если в группе много открытых страниц-то хочется их закрепить. А если закрепляешь-то при открытии новой группы закрепленные страницы открываются и в новой группе. Если бы это можно было бы исправит-было бы здорово

It's fast and almost never crashes at least in my case, which makes it even less time-consuming than the old add-on. One thing I don't like about it is that it messes the order of the tabs when switching from one group to another. Hope the developers will fix this issue in upcoming updates. Then I guess it'll deserve a 5-star rating.

Great addon, makes me forget old native tab groups. Improving a lot

UPDATE: AS per Drive4ik's reply, tabs are kept open when moving between groups. Good Job!

I would really enjoy this extension if it didn't close and open tabs when changing groups (the old extension would hide and show tabs, not close and open them). I understand that Firefox did not give much control over tabs until recently but I believe they do now allow control of visibility so there is no need to close and open tabs when moving groups

It is a first that is nearest Tab Groups.
Make it better tabs overview (managing groups) and you have 5 stars and recommendations from me!

Works almost as previous "Tab Groups" add-on. I'm waiting for possibility of displaying group name instead of colour

Good Addon. Not sure if the means of always closing tabs when switching groups is a generall problem with firefox 54+. Ofc it would be nice if they could stay opened. Let's see how it goes in time.
One other bug is, when I close the browser and reopen it: the tabs from my session reopen without a problem (they are not lost) BUT they are in no group anymore. Would be nice if the addon recognizes this was the old group and uses it. Workaround (and general nice feature) would be: when you right click tabs you can move them to group, so having a second option, when clicking on a tab to "Move all open tabs to group ..." would help a lot :) so I at least dont have to click on every single Tab of a window. Good work so far!

I don't like this addon at all. Like other people are saying, it closes all tabs when I switch a group to another. Why do you do this????
Other users seems quite happy with this add on so maybe its just a few of us???
I don't know but I'm not gonna keep using this.

Great replacement for removed built-in tab groups! Simple and easy to setup.

Inactive tabs are out of memory and need to get reloaded becoming active again.
This implies long lasting loading times.
This also implies that active plugins (e.g. audio playback of a tab) stops when the group is changed.
I just want tabs to be grouped, nothing less, nothing more.

I modify my appreciation and give 5 stars insted of 3 because now this module is perfect for me.
Bravo to the author.

I gave this addon the second chance, and it works great! The only feature I miss is exporting/importing specific groups in the addon.

Better than original Tab Groups, best tab manager, works in all modern firefox versions including latest nightly, very well done job, thanks a lot.

Super helpful! I'm one of those people who has over six or seven tabs open all the time, and this makes managing them *so* much better. Thanks!

The best addon. Saves my time. And helps me stay focused.

Works really bad. This addon doesnt actually just group tabs. It CLOSES the active tabs, then loads the tab in the group you selected. If you want to go to some of the tabs in another group, well too bad, because now you have to RELOAD them again.... sigh. terrible. We just want the tabs to be grouped, that is all. Not closed, not reloaded. Just grouped.

This addon is getting worse and worse... I don't know why the dev is wasting his time on these stupid workarounds for the tab hiding issue.... Firefox added the ability to hide tabs weeks ago, stop fucking around with these idiotic workarounds and implement it properly. These idiotic workarounds are just making the plugin do some really erratic shit. For example: https://i.imgur.com/7oWdnuj.png

I did not create a single one of those groups. So now in addition to randomly creating groups (which it started doing a week go or so), now it seems to be populating some of them with tabs from sessions that ended a long time ago. I did not have those 86 or 116 tabs open the last time I closed Firefox. There are even duplicates in those two groups... I don't know where or how the fuck this addon decided to create those groups and populate them with tabs that I closed days ago, but there you have it...

You should go back to how you had the addon 3-4 weeks ago, and then focus only on writing in the tab hiding functionality. All this crazy shit you're trying to do with closing tabs and then reloading them with the moz-extension bullshit is not working at all, and it was a pretty stupid workaround to begin with.

If you were a die-hard Tab Groups user, this just might be the only way forward for you with FF Quantum.

I tried many replacements for Tab Groups until this add-on came out. In my opinion, it's the only one that even comes close (unless there is a proper re-write of the original Tab Groups for FF Quantum).

There are some bumps along the way - some of them are Firefox bugs, some of them are add-on issues - but I think the developer has been doing a great job of maintaining this add-on and managing expectations.
