[Edit] I found on Github that there is newer release - I am waiting for publish [/Edit]

Since few days it prevents Firefox from start. I can't even figure why. I had removed every old sessions, cleared cache and extension storage and reinstalled couple of times. Checked if there is any conflict with other add-ons, turned them all of and then on again, one by one - and every time I turn on Tab Session Manager browser stops work. Nothing helps.

Will randomly reset its shortcut keys even after you've removed them.

June 2024


"This issue will be fixed in version 7.0.1."

"For now, the only thing you can do is go to TSM Settings > Startup and set it to 'Open Startup Session' or 'Do Nothing', then Firefox will at least open and the previous tabs can be manually opened from the TSM Toolbar Icon.

If you need to open Firefox in safe mode, hold down the shift key and then click/double click on the Firefox icon. Once open in safe mode, you can then disable the TSM add-on.

Close and restart Firefox in normal mode, re-enable TSM and then go to the TSM settings etc. From there on, you will need to manually open any saved tabs from the TSM toolbar icon in Firefox, at least until TSM v7.0.1 drops."

To quote user tuna's review a day ago
"Firefox has not been able to start since the June 4 update."
I have the exact same problem and in order to make firefox start normally with the extension enabled, i have to start a private browsing session which opens two windows, one with one tab in private browsing and a second normal one with all the tabs that the extension has saved. Otherwise the apllication is killed almost immediately after starting with the extension enabled.

Please roll back! My Firefox ESR Portable crashes at startup since the last update :( and this addon is essential because the native session manager sucks!

Firefox has not been able to start since the June 4 update.
Correctly, it starts once, but Firefox goes down without restoring tabs.
I have now disabled the add-on.
Please remove the cause as it is a great add-on that is very useful.
Or tell me how to deal with it.

This review is for use on Firefox. I have tried different addons to save tab sessions and this one, Tab Session Manager is the only one that works 100% of the time. Thank you for this addon, saved my butt many times.

Отличное расширение, упрощает работу в браузере

It was working for me, but recently I've started getting massive memory leaks (like Firefox takes 8+GB of RAM and continues to take more causing swap and everything works slowly). After turning this extension off, all is back to normal.

Installed this a long time ago and forgot it was there. Today, Firefox lost my open windows history and I was panicking until someone reminded me about this extension. I used it for the first time and it rescued everything!! Thank you sienori!

I love this extension. Thanks for your efforts!

I've used this add-on running pretty much in the background for years and the auto-save feature saved my butt from accidentally closed windows a few times. It was like a nice browser session insurance policy. But the user saved sessions feature combined with the new*** tracker feature is just brilliant. Now this add-on is saving me from a personal multi-opened windows with multiple tabs hell and has become a legit sessions manager for me. And the sync feature to Google Drive continues to be rock solid and one of the few add-ons that does it correctly (it just works). I just donated to the dev so I'm putting some money where my mouth is. ;-)

***Well I've since discovered this feature was released in May of 2022 so I guess it isn't as new as I thought (which was Sept. 2023). And it has some quirks around sessions opening at startup where you have to close the session and re-open it to get tracking going. I'm more concerned there haven't been any significant updates since Sept. of 2022 and I hope the dev isn't slowly abandoning this project. :-(

I've been using this add-on for years and I'm so happy with it , the only problem is that when I automatically loads the session at FF start , it opens a new window other than the one I already opened , I wonder if there is an option to make the saved sessions load in the same window I have already started
