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!

Third time I've used this add-on and yet again it has deleted months of multiple saved sessions.

How can this add-on be listed as "Recommended" by Mozilla when it is fatally destructive to users workflows because it is so unstable? It should be removed entirely until the creators fix this glaring failure.

I have saved hundreds of bookmarks in Firefox for over 10 years and they haven't randomly disappear, so why can't OneTab write an add-on fit for purpose?

About every time you go to a new release of your browser, you take the chance ONETAB WILL LOSE EVERY ONE OF YOUR URL'S YOU GAVE THEM AS THERE IS NO RECOVER process if you have to create a new "profile". There is NO BACKUP. "EXPORTING" them is no protection as they do not let you recover, tell you where they are stored.... Since I used to use it, about every year or two, I lose them all due to no backup, etc. JUST DO NOT DEPEND ON ONE TAB to take care of them. Find another way. In a perfect world, they might be ok.

Really useful! It is simple but more effective than other very complex addons

An error cause can't export or import any tabs.
Sync open or delete not work too.

class ro {
constructor(e, o) {
this.Ho = o;
// ERROR: e is null
this.url = e["url"];

Не открывает локальные файлы.
Doesn't open local files.

I've used this for years and it has been very convenient for saving many tabs at once. Some bugs over the years but it is simple and effective. Highly recommended if you "hoard" a bunch of tabs at once and never close them at the end of the day.

I've been comparing session manager types of add-ons, because I use a lot of tabs. With this one, it didn't *appear* to have the "lazy loading" feature, where pages aren't reopened until you click on them. Other session manager-style add-ons (tab session manager, mysessions) have this. I restored 300+ tabs with OneTab, and it used all my memory, and brought the machine to a halt. I waited for all the pages to load, and finally gave up. No one needs to use 300 tabs at once! Doing the same operation with tab session manager (for example), the 300 tabs open almost instantly, with minimal memory use.

Wow! This is an extension I never knew I needed! I have more than 300 tabs open at any given time, mostly for reffering to some content later on, and this is a nightmare for memory and processing resources. OneTab neatly put these all in one tab and I can restore and refer to them as needed, then add them back to OneTab when done. Bravo!

Suggestion: It would be great if there some sort of grouping I could do within the clickable list of tabs that OneTab creates. That would really help my productivity increase.

Fantastic App
But has 1 fatal bug.
I tried to restore 12 Tabs. It only restored 2.
No error Message or anything.
The other 10 Tabs are now lost forever. Please look into that.
Would get 5 Stars otherwise

It's great, but doesn't remember what container a tab belonged to. So it restores tabs to the default container, which has lesser privacy.

A dark more would be great (or support Dark Reader).

I decided to use OneTab and it seemed to word, BUT when I went to open the tabs they were NOT THERE!
I would not this software unless you want to LOOSE all your tabs!
