OK, turns out I was wrong, although it seems to have started when I started using OneTab. I'm rating it 4 and try and start with a fresh profile for FF Quantum. Will see what happens..

It could have been a great addon, because it is quick, nice, and easy... but there are 3 main issues with OneTab :
- Issue #1: All the tab histories are lost. Only the last page is retained. This is certainly the worst of the issues.
- Issue #2: local page like about:addons are well in the OneTab group, but can't be restored.
- Issue #3: If I enable the addon "Open Tab Next To Current", then when I restore the OneTab, all the tab order is reversed.

This is by far the most useful extension I've ever used.

THIS TAB "Bucket" is a great way to get neat - and orderly - and faster browser - with ONE CLICK.
Try it, you'll like it. I certainly do - on ALL my BROWSERS!!!!

Could use a better, cleaner logo. Perhaps just a single color, more sharp edged shape? Like an upside down triangle with a small line coming out from the bottom. Just in blue.

Great functionality, though. Looks like it'll be extremely useful.

Also, a simple lock button on the side of the tabs in the OneTab menu would be superb, as opposed to clicking the "more" option each time you want to lock/unlock something.

Love this add-on! It is EXTREMELY useful!

Clean, simple, flexible, powerful. What more can you ask from a utility extension like this?

Its a great addon , helped me a lot

100% good

Exceptionally helpful. The more I use it, the more use I find for it.

Works Fine, but needs to improve on "pinned tabs" : they are not moved to onetab, which is good, but restore all" opens in a new window without the pinned tabs, and then you have to manually merge these two windows :(

okay

Genial, ahora que Firefox consume tantos recursos. Fácil y cómodo de usar, funciona perfectamente.
Le faltaría poder guardar las listas de páginas.

One of my secret weapons either on firefox or chrome, thank you for creating this great extension...
