User reviews

Tab Session Manager is praised for its simplicity, reliability, and effective session management over several years. However, multiple users report issues with automatic saving especially after recent Firefox updates, resulting in loss of large tab sessions. The autosave feature creates duplicate sessions cluttering user space. Some users also note that it does not maintain certain tab statuses and that developer support is lacking. Overall, it is a useful tool but faces stability problems impacting large sessions and autosave behaviour.
Pros
  • Effectively manages sessions and tabs over multiple years.
  • Simple and reliable to use.
  • Supports multiple browsers like Firefox and Opera.
  • Generally good session management features.
Cons
  • Recent Firefox updates have caused issues with automatic saving.
  • Loss of sessions with a large number of tabs reported by multiple users.
  • Multiple duplicate session saves created by autosave, leading to clutter.
  • Lack of response from developer regarding reported bugs.
  • Does not preserve certain tab statuses like protected or muted tabs.
Recent reviews

This is an excellent and convenient extension that I've used for years. It has saved me many times when I would have otherwise lost all my tabs. I love that I can create manual and automatic saved sessions and even back up to the cloud or export to a local file. If possible, I would really love the ability to backup up tab groups. I know that it is a really new feature and I don't know if extensions have the ability to do that, but it would be very helpful. I think that it would also be nice to have a feature to pin some sessions to the top of the list to make them easily accessible.
