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.

Good until Firefox updates or your computer crashes--then say goodbye to your tab hoard! They will be permanently lost.

AVOID IT! All this extension will mostly end up doing is causing loss. It is known to randomly or unanticipatedly lose all or data. You have been warned.

This extension did not do what it says. Took control of my browser and would not give back control until I uninstalled it. It still did not uninstall completely and has its own icon in the top left corner of my browser instead of Firefox icon. Hosed my tabs and lost my data. Had to restore my session by restoring one tab at a time from my history. TOTAL GARBAGE

This add-on is very useful and work as intended most of the time. You just have to be very mindful to export your tabs for backup every now and then, so you don't lose them. If you reinstall OneTab or your browser, you will lose all your saved tabs. So use the "Export / Import URLs" feature. The app lack important features, so I withdrew one star.

it works until it doesn't. And when it doesn't, it makes you lose all the tabs that you just saved. I lost over 50+ tabs because it just stop working.

I sent them this feedback:
"click the OneTab icon to convert all of your tabs into a list. " please make this disableable. I left-clicked the icon accidentally and lost a ton of intra-tab-history.

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.
