If you are using Firefox or any browser, this is a MUST-HAVE for folks like me that consume Data and often have more than 10 Tabs open for Research. LoL. Been using this for over five years now with no issues.

I will start with my disclaimer. It is extremely rare that I write a review but I have to thank all the human beings responsible for this wonderful add-on. My work requires to perform research as well as obtaining specific information regarding medical management. I have been using One Tab on Firefox on my Intel 3770k dinosaur since April 30, 2024. When I perform research I have run with more than 132 tabs opened in one session with many other applications running at the same time (usual behavior). This add on has flawlessly helped me in avoiding computer slowdown and almost crashes. It has never lost any tab to this day. I will love if I could back up all the sessions tabs at once instead of going session by session to either text links or as html. Thanks again for this useful and genius add-on.

3 suggestions that I think would make it even better:
1. Export as json/csv - Would be useful so that I don't have to keep a .txt file laying around with the urls and instead have a formatted json/csv file.
2. A way to search through the links on the OneTab page, currently I use ctrl+f to do this, but I think it would look nicer if it had its own search or if when you searched it narrowed the results down from all your tabs so there isn't a bunch to look at.
3. A more secure way to save OneTab tab data that isn't exporting/importing them. I'm not sure how this could be done, but according to dozens of reviews, their tab data was lost for seemingly dumb reasons that shouldn't occur.

Awesome add-on. Simple and most convenient.

Just one little thing, when exporting/importing the group names are lost.

One of my favorite extensions for Firefox. It has its limitations but suits my use cases just fine. If there was one thing I would wish for it is the ability to intelligently sort and categorize tabs.

One of the best Firefox extensions.
I only have one suggestion, an option to send only selected tabs to OneTab, because sometimes I want to send 2 or 3 specific ones and there is only the option to send all to the left or all to the right.
