Amazing add-on. I use it to store tabs temporarily for later use in addition with Session Manager (which I use for long-term storage). I used have a lot of tabs open and am not willing to close any of them, so this has helped me out a lot since I no longer have to wait forever for Firefox to load a web page because I have 300+ tabs open. Definitely a must have add-on for any tab hoarder.

Just works. There is a difference between "I don't want to save this, but I will get back to this later" versus "I have read this and bookmarked this for reference". While bookmarks solve the latter issue, one tab fills in the gap for the former. This is very useful to me and saves me from the bookmarks route where I am very particular about organizing my information for quick access. Also, it has a quick-glance friendly visual page view of everything, instead of a sometimes cumbersome folder within folder complexity of bookmarks.

this is so great and so simple.. it is a must have for every browser.. i wonder why other browsers dont have it :s

10/10. lets me stash all my porn for even faster opening.

This is so simple to use, and so effective. Bring order to chaos. The first extension I ever install with a new browser! <3

A very good tool in memory-scarce computers. We developers all know that we can't keep only 3 or 4 tabs open. So keeping track of them without them being in the memory is a very nice trait.
Thank you :)

This tab makes managing tabs really easy!

This is the best extension I have ever used for temporarily or permanently creating and storing bookmarks. Very easy to use, much more so than Firefox's built in bookmark system. You can name a tag group, give it a star so that the group always shows at the top of the list, and lock a group so that the links within the group will not be deleted unless you delete them. I love it.

It's hard to explain how much of a quality of life difference it makes just being able to create dated groups of links for my tab sets rather than leaving them open as tabs that I will hypothetically get to at some point in the future. If you're not a So Many Tabs person you wouldn't understand. If you are, try this. Don't forget: you can export your data to carry it between instances of the add-on!

Very handy tool, save memory & prevent me to bookmark pages for later

Easy way to quickly bookmark and close large numbers of open tabs. Many useful options, including the ability to share saved links as a web page. Highly recommended.

That feel of having exactly what you dreamed of and the developpers are having the same good ideas you even didn't think to ask for... A little add-on that is absolutely fundamental to me, one of the first I install when I set up a new Firefox somewhere (please Mozilla, if OneTab Team is ok with that, consider integrating it in next versions of FF).
