OneTab is an immensely useful extension! I use it to keep track of projects, hold collections of favorite sites, and send batches of research to my friends and colleagues. The support team is also very responsive and helpful, and they released an update fixing an issue I reported within three days! Would very much recommend OneTab for managing your web browsing!

This addon is fantastic! Firefox's newest update did mess with it a bit, but the Onetab team quickly fixed the issue and now it's working again perfectly! You just have to update OneTab andeverything should work, with no data lost! The Onetab team responded quickly to my support request and I'm very impressed by their dedication. This addon is so so nice and I wouldn't be able to enjoy the internet without it.

Update 2/18/2021--I still love this add on so much! If I didn't have it i simply would not be able to function on the internet without it!

The latest update fixed the previous issue. Thanks.

Despite the recent glitch that was a FF issue to begin with, OneTab remains one of my favorite add-ons...

OneTab has been one of my favorite addons for a few years now. It's simple, easy to use, and always maintained. I highly recommend it to anyone who needs to organize tabs and keep them for later, or even share them with someone with just one click.

Love this extension! It finally allowed me to stop saving temporary links to my bookmarks or notes and cleaned up my browser. I use it every day! The development team behind the extension is great, very responsive to any problems or bugs (which are rarely the case). It's a must have for everyone!

Great app, always being maintained, they had a bug for a few days and quickly fixed it. They get back to you when you contact them, and are constantly working on adding new features.

Really great tool if you want to keep group of tabs that you want to open and close together (e.g. a group of tabs for work, a group of tabs for studying, a group tabs when playing, etc...). Really appreciate the devs for rolling out the update on the usability issue on firefox.

Honestly this addon has been a life changer for me. It's almost as valuable as uBlock Plus imo.

I've had it for a long time now and the only issue I've ever experienced with it was this past weekend, but I emailed support about it and they were quick to put out a fix and give me an update on the situation.

I really hope people update their reviews because they couldn't wait a couple days. Because this extension is totally worth it.

Secular Simplicity, love it. For those with inaccessibility issues after each/any Firefox patch/update, simply remove and reinstall the OneTab Extension; no complaining required.

This is the best tab management tool. Everything else is over-complicated.

solution to update prob ...

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!!
