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.

1-27-25: works pretty good but lacks essential features:
entries won't survive cache clears even if "locked". No way to organize and easily edit urls. Slow to load sometimes won't requiring reinstall or reload.
10-10-24: still good not perfect but pretty good.
aug, 2024: it's gotten much better. Recommended
Sept 2022: It's gotten better but the thing that remains that is really annoying is that it won't load the saved urls automatically and you have to disable and re-enable it to get the saved urls to load. The problem with the auto opening of the tabs has been resolved in their settings, so that is not an issue now. But I am sick and tired of having to disable and re-enable it to get it to load on command. I dont' want AUTO load but I do want them to load when I issue the command.

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...

Please include a dark mode and search function.

Could be an excellent Add-On, but has problems with keeping data when Mozilla releases new firefox versions. I recommend strongly to frequently save links to a text file. Otherwise you must restore lost tabs from firefox' history.

Пользуюсь во всех браузерах. Нет резервирования списков - приходится делать это вручную.
В Firefox 80 периодически "пропадает" OneTab - приходится идти в меню "Расширения" выключать и снова включать OneTab. Несмотря на многолетний стаж расширение недоработано, на мой взгляд. С первого момента его создания, сколько бы оно не обновлялось, не вижу никаких улучшений. Жаль, что хорошая идея не реализована в полной мере.

A very good addon until the last update. Now I have to disable and re-enable it each time I open firefox to get it to work.

Je trouve cette extension vraiment bien MAIS elle se désactive systématiquement à la fermeture du PC!!! bref si ça continue je chercherai une autre application. Décevant

Giving this a 3 star because its a great product, however their latest update really botched everything. For people looking for a permanent solution unlike the disabling it and re-enabling it (only works until you restart Firefox), you can first back up your tabs using the methods many other reviews have outlined, then scroll down the OneTab page to the More Information section. Here you can click on the link to previous releases, uninstall OneTab and then install version 1.29 and restart Firefox. You may also want to disable automatic updates in the extension settings so it doesn't update again, and this WILL clear any tabs you have loaded in it, so remember to back up the folder before restoring it afterwards. Hope this helps and doesn't get buried instantly.

all tabs gone, disenabling and then enabling the addon again resolved the problem

I lost OneTab button on the top left of the window and in addition, the tab list page displayed nothing.

I turned off (not deleted) OneTab, restarted the firefox, and turned on OneTab. Then all came back in my case.

Also, URLs of the tabs seems to be written in extension@one-tab.com, which is a subdirectory (subfolder) of the directory (folder) of firefox or mozilla.

I'm glad if this helps you.

This is a must-have extension for avid Internet users. The problem is that the recent update caused the extension to stop working, and I lost all my tabs. It seems that many users suffered the same thing.

I'm also a developer and I just can't imagine shipping a new product version that breaks everything so drastically.

Lesson learned. Never depend on any tool. Tools can be wonderful, but you never know when they are going to break.

I will rate with 3 stars because addon developer created this addon. If mozilla made this add-on then I would rate it with 0 because it doesn't even deserve a rating of 1. I am still using Tab Groups because groups are totally hidden and I can backup all groups and tabs with just a few clicks. In less than 1 minute I have 100+ tabs on my laptop.

What I need to do is foud a developer, then pay him to hack Firefox version 54 and change it with latest firefox version.

Latest firefox versions is totally the same as any other browser -> GARBAGE.

100 tabs use only 1 GB of ram :D why do we even need x64 if browsers are NOT even created to run more than 10 tabs!!

Running 50+ tabs without Multi-row no thanks!! I will not have my tabs in second window, because Multi-row do the job perfect and I can see tabs names without clicking on anything!

I like browsing fast and with less clicks and not with more click to do the same!

For example new sidebar oh my good!!! By default sidebar on the left side and icon for open/close sidebar on the right side :D :D :D Every time moving the mouse on the entire screen :D do they even have brains??!
