This add-on is a brilliant idea. It's quick and easy to save tabs out of the way until you want to go back to site. Can even organise tabs into groups and rename them too. This is great when researching different subjects. I've been enjoying the useful functionality of OneTab for ages now. A really useful way of bookmarking.

Until the last update (16 September 2020). It is now completely broken. When it's fixed I'll come back and update the rating.

Brilliant!! Problem quickly sorted out. All data restored too!!
I guess we expect things to go wrong sometimes but the way the problems are dealt with is very important. So many businesses today don't seem to care, but the developers here have acted quickly to resolve the issue and get us up and running again. It even looks as though they have taken the trouble to reply to every single person who has raised the issue, not just posted a response for people to find! I even had an e-mail from them. That is true "customer service".

So in conclusion, definitely five stars, both for the add-on itself and the developer's support!!
