Tab Session Manager by sienori

by Firefox user 13495313, 9 years agoIn older FireFox(FF as follows) than 57 (ver <=56), "Session Manager"(S-M as follows) did a great job.
But in FF ver 57, S-M ended its life, due to the FF's change, cut off "XUL", which used in S-M, and moved to "Web extension".
This TSM seems an good "ALTERNATIVE" of S-M "JUST" for *FF 57*, for me.
TSM is *NOT* a successor of S-M. Different developer makes TSM than S-M. Words of "Session Manger" in TSM made me confusing, for the 1st time. If its name was "TAB MANAGER", might not be confusing for me.
You don't have to take risk to move from S-M to TSM, if you are still using older FF(ver <=56) or PaleMoon, which still has XUL, which is cut off in FF57. (I still use S-M on PaleMoon)
***
Following issue was fixed in TSM 1.6.1, using "tab lazy load" option. (FF ver 57.0.1 x64)
Good job! (2star -> 4star)
***
at TSM ver: 1.5.0, FFver: 57.0 x64.
"Open" with 100-200 tabs with 4 windows saved, only 1 window opens and 15-20 tabs only resotred.
With or without Tree-Style-Tab. Even in case of tabs with only http/https-style, this occures.
Exporting sessions from this extension, 4 windows and 100-200 tabs seems all saved in the exported file, instead.

- Rated 4 out of 5by OMIDT, 14 days agoVery High CPU usage on many tabs.
Other wise is amazing tools i am using all the time. because of this issue i have to disable it and enable all the time to avoid my CPU fan go crazy. - Rated 1 out of 5by Firefox user 17633691, 16 days agoGarbage extension. Can not find specific previous session. UI absolutely terrible. I can not emphasize how much I hate this PoS software. Uninstalling.

- Rated 3 out of 5by Firefox user 18514632, 20 days agoCloud sync is broken, infinite loading (Same thing like GitHub issue 1451). Suggested fix to delete all data does not work.
May work well for local-only use. But extension explicitly advertises cloud sync feature. - Rated 1 out of 5by Firefox user 20033380, 23 days agoDo not use this on browsers with multiple workspaces like Floorp - it moves all the tabs to one workspace, rendering the extension worse than useless.

- Rated 3 out of 5by Altus, a month agoThe addon is not bad, at first glance. He copes with the assigned tasks, BUT very frequent begging for money (donations) is very annoying. I even started writing down the dates when the internal "thank the author" timer went off.

And I was just opening a window to clear saved sessions. - Rated 5 out of 5by Firefox user 20008329, a month ago
- Rated 2 out of 5by AlexOja, a month agoSoliciting money all the time. Clunky. Sync tends to clutter everything because default settings haven't been thought through well enough. Does work pretty well, but if you're going to bug me for donations all the time, I'll just uninstall.

- Rated 4 out of 5by Erick, 2 months agoCan you add local support for the addon to remember spit view tabs? thanks
- Rated 4 out of 5by Katherine Howell, 3 months agoOne of the best extensions I've installed. Simple, effective, and doesn't bloat the browser at all.

- Rated 3 out of 5by kone, 3 months agoBetter than Firefox's built-in backup, but unnecessarily complicated!
I don't see the point of many of the features. Unfortunately, there's no help section to clarify this. - Rated 5 out of 5by Mimrix, 3 months ago
- Rated 1 out of 5by Firefox user 14498287, 4 months agoFrom the volume of open issues and the lack of activity on Git, It looks like Sienori has either abandoned this extension or doesn't have the time to maintain it. April 26.
