hello, Currently I do not know of a way to do this. I believe the tabbed groups are stored in the session file of the profile, however this is not a file that is synced. Currently active tabs sync when both devices are attached and actively synced (about:sync-tabs), Tabs, bookmarks, preferences, history etc

Tabbed-Groups does not seem to be on the dinner plate at this time: https://bugzilla-dev.allizom.org/show_bug.cgi?id=589336 as it was concluded that it is a won't fix bug at the moment.

As a work around there is also Firefox portable, but it is supported by a third party.

I want to have all my tab groups sync on all my devices. Thanks in advance :-)

The reply given takes it that you are using the almost deprecated Tab Groups

• As described here Use Tab Groups to organize a lot of tabs

It is possible in fact you are just asking about collections of tabs maybe as bookmarks or as tabs open in a session.

• How do I choose what information to sync on Firefox?#w_what-types-of-information-can-i-share-across-my-devices

Please Take Care IF Syncing Bookmarks Should you elect to Sync Bookmarks please be aware that Firefox Sync will occasionally corrupt and|or duplicate bookmarks, especially if a slow connection or many changes are involved. It is almost impossible to fix such corruption and you will be forced to use am unaffected backup, because of that it is vital you make manual backups of bookmarks. Rather an ironic paradox! You use Sync to backup bookmarks then need to resort to manual bookmark backups because of Sync.

I am not too sure why Firefox Portable is mentioned. If you are using Linux that may not be appropriate.

Assuming you have the space and resources multiple copies of Firefox may be run on a single desktop OS account &|or multiple instance of Firefox even simultaneously. Relatively easy to do

Not quite what you are asking about but it may also be of interest to note it is usually even possible to drag and drop between Firefox bookmark manager windows. (That may include between clones|variants like Palemoon and Iceweasel not just Nightly & Beta)

^thank you John :-) I learned something about portable.
