Can't open 600 tabs

I used to love this, but I found out that once you share your tabs, those get indexed in Google, be careful.

I am absolutely done with this add-on. It works great, until it doesn't. For the fourth or fifth time now, over the course of the last year or two, I click on one-tab only to discover that all the tabs I have been saving for the past few months--all the organization and labeling--they're all gone. As if I'm starting from scratch again. I'm so frustrated. There has to be a program with this convenience that doesn't screw me over entirely in the end.

I added this extension to move my tabs from Chrome to Firefox. I shared the tabs from a Chrome window in a webpage. I do not see a way to "Restore" the tab list to a window in Firefox without opening each of them individually.

Tried this on a fresh profile. Very stupid behaviors:
- Click the OneTab button, it will close all tabs, thus the name OneTab. But I usually just want to stash one or several tabs, not all. To achieve this, I must right click. Very annoying.
- When you open a session, it will load all the tabs at the same time. NO! They should be in dicarded state, and load on demand.

So my conclusion is, I will not use this addon.

For those who have lost tabs, I discovered that selecting Exit from the hamburger menu instead of X (close) avoided loss of tabs. Also, if X is clicked by mistake, I found that restarting my laptop (or possibly just closing Firefox and reopening it, I'm not sure) restored the tabs I had open.

When first opening Firefox, a succession of several sessions, one with only 1 tab and others with a group of tabs, rapidly appear before displaying just one session with the right group of tabs. I'm now going to disable this add-on and stick with Firefox's "open previous windows and tabs" option.

Edit: The behaviour above (2nd paragraph) still happens even after disabling the add-on, both with X (close) and Exit. AND this edit paragraph is missing (despite definitely clicking Update review) if closing with X!!

Mod strongly discouraged.
I usually set my windows or tabs using firefox bookmarks and it works fine.
But Onetab when it opens them again the tabs are all UPDATED AT THE SAME TIME!!!!
As a result, I reopened a window with 70 tabs and they were all updating 1 by 1 and loading all 70 at the same time, instead of doing what bookmarks do and putting them on hold.
So it took 20 m and crashed.
Fortunately, I was able to get other windows, the one it hadn't tried to open or the one where I'd put a lock... but when I relaunched the one that was loading, I had 6 tabs out of 70 ... lost forever ...

Doesn't even show on the addons bar, tried restarting but to no avail. Sad.

AVOID IT! All this extension will mostly end up doing is causing loss. It is known to randomly or unanticipatedly lose all or data. You have been warned.

This extension did not do what it says. Took control of my browser and would not give back control until I uninstalled it. It still did not uninstall completely and has its own icon in the top left corner of my browser instead of Firefox icon. Hosed my tabs and lost my data. Had to restore my session by restoring one tab at a time from my history. TOTAL GARBAGE

it works until it doesn't. And when it doesn't, it makes you lose all the tabs that you just saved. I lost over 50+ tabs because it just stop working.

Great idea but I can't get it to work as described

Used to be great and really reliable, but more recently, it has really sucked, having lost my entire list of tabs several times now. A shame because it was really great when working as it should. But given I had important stuff I needed to come back to in those tab lists... yeah, not happy. Just glad I've been a little deficient in clearing out my history in the last couple of months, so most of those links are at least somewhere.

Installed, clicked it, lost 100 open tabs.

ADD-ON IS BROKEN!

Lost my tabs two times in a row now..

Author kill youself! WTF where is easy ability transform all the pages from one to many?? I los a lot of time with you raw stupid app.
