This add-on is the best there is for this kind of functionality. After 50 years of evaluating software, I have believe the simplicity of relationship between screen design and functions is responsible for the best software, as long as it works and does the functions. Session Sync does all three well. I have not encountered glitches and it is far superior in user interface and functionality, than any other tab manager.

I had issues with another add-on that did not behave properly and also interfered with Session Sync. When I had this problem I researched and used other tab managers. They don't come close. By deleting the errant add-on, Session Sync is back to working flawlessly and I can dump them!

The developer communicates in a responsive and timely manner, and actually works with you to support the product.
