When I re-install my system, the all web is gone...how to find them back? It's horrible.

Great Add-on BUT it stopped working several times and made the saved Tabs inaccessible.
No response from the developers. :((

Bookmark icons disappeared after browser update.

OneTab does what it says, but I wish it had the option of moving single tabs to the list instead of all of them at once.

Essential but, can't select multiple tabs to move as a group. When I saved 550 tabs 70 of them did not save or close and still won't. No other place for feeedback

Its good but there is a slightly annoying behaviour where it will open 2 firefox windows when starting firefox

It would be much better if there is a setting to change the default behaviour of the main button to just save the current tab instead of all tabs. I never want to save all the tabs.

Good, but Tab Stash is much better

Needs Dark Mode!

Note that using this will take out the tabs in simple tab groups. I assume TabMerger will do the same.

The tabs cant be opened in "incognito" mode. An option should be added to do so... Or at least an option to select the tabs wanting to be opened in private/incognito mode.

Functionally the Add-on is amazing and I can't believe how I never had something like this for tabs.

That said it is way too bright. To the point where I don't manage my tabs at night because the whole window is basically a flashlight pointed right at me. A dark mode would be greatly appreciated!

I want dark mode.
Or I want you to support "DARK READER" .

Buena; falta arrastrar pestaña a onetab.

Nice tool, but i missig a chance to group my tabs.. after starting addon my list contais more than 80 Tab . Thats nice but without any chance to order by categories.
some of my tabs are needet for read later or redraw .. ff speed increases realy because of much less memory needed but the list is confusing.

I found the almost perfect replacement for Firefox's (before v.57) TabGroups. OneTab fully closes the tabs and reloads the websites on restoring the tab. However, if this is what you need, OneTab works wonderfully.

June, 2022: It's gotten better, easier to use. On some browsers such as epic, it will not auto activate and you have to disable and reenable to get it to show. Need a better way to save the tabs when it goes haywire. Should have an auto setting to automatically lock the tabs.

Demoted this add on to ONE STAR.
It acts like trojan or malware and opens a second FFOX window without user input and with setting set to open tab only, ignores the setting and opens a new window. Reported as malware.
mostly disabled it. Breaks Loads whether you ask it to or not and then breaks your vpn or music connection in doing so. Seems pretty obvious they are messing with your other browsing connections. It's only good for one thing, that is if you have to open many URLS and don't want to bother pressing the keys to make a book mark. I consider this spyware. Don't know why mozilla recommends it, but they must have low standards.

Very useful, but it's almost entirely in bright white with no Dark Theme/Mode, which is a pain, especially at night.

Space useage and font size are also not the most ideal either, there's a lot of unnecessary spacing, and the font for most elements is too small on a 1080p 15.6" laptop. Spacing/Padding should be reduced, and there should be an option to change font sizes.

Works fine but lacks the ability to gather pinned tabs even using its option to send all tabs to OneTab. Would be nice to be able to merge all sessions into one and sort by name and delete individual items...
