Extension version 4.5:
I typically perform a manual backup before every quit of Firefox.
I'd like single-click backup.
Realistically: there's nothing (no separate toolbar icon) on which a single click can be effective. Instead, maybe:
To the best of my knowledge, no session manager extension is compatible with Simple Tab Groups.
If you select the backup option to the file once a day in the add-on settings, in this (and only this) case, the addon will backup every 2 hours and overwrite the file by the current date. You have a fresh backup with an interval of 2 hours.
To the best of my knowledge, no session manager extension is compatible with Simple Tab Groups.
If you need to restore a session or something else, disable the STG addon, restore the session and enable the STG addon. Otherwise, the connection between the group and the tab will be lost, since it is in session, and the addon has no idea that another addon will now restore or close the tabs. That is the problem.
Thanks, the intention is to have a streamlined backup on demand (in addition to scheduled backups).
I once had a corrupt session, resulting from a kernel panic, recovery from which quite painful.
I already have auto-backup set to one hour so (for example) 204 files in STG-backups-FF-76.0 and 41 so far in STG-backups-FF-76.0.1. I'll occasionally manually weed most of the oldest backups.
I added a backup hotkey. #602
It will not call the save file window, it will just backup based on the backup settings of the addon. Will it be okay?
Sorry, I only just read your comment.
I don't see the feature:

@grahamperrin
Sorry for the long absence, I made changes but I haven't released the new version yet. There will be a new version soon and will include this change.
Found (thank you).
For now, I choose Control-Alt-B.
From https://github.com/Drive4ik/simple-tab-groups/issues/621#issuecomment-782992080:

– result:
A repeat of the shortcut, on the same day, will overwrite the backup. This is reasonable; it avoids proliferation.
PS
Sorry for the long absence
No need to apologise!
