lost all tabs in onetab

this thing dont work:

"Data safety

Don't worry about closing OneTab - you will not lose your stored tabs. Even if you close all tabs and exit your web browser and restart your computer, the tabs you have stored in OneTab will not be lost. "

Does not work on android. Closes all tabs but only saves like one or two.

Ate 50 tabs of research, saved three unimportant ones. Could've used something like the right-click context menu available on desktop to save a certain group of tabs one by one like I had wanted to.

Took over 100 open tabs and converted... one of them. That was it. That was all.

Had 64 open tabs and it only converted 4 of them :(

Absolutely useless. After restoring tabs Firefox tried to load content of all tabs at once which resulted in an infinite loop of loading without any result. Had to kill FF with the Task Manager. Lost all tabs. Avoid.

I tried this add-on today, having so far been fairly pleased with it on FF for Windows. I had 30 tabs open on FF for Android. OneTab saved the most recent three and deleted the other 27 from existence. The fail is impossible to exaggerate. I will probably remove this and hunt for alternatives on FF for Windows too.

Used to have this on Chrome in 2018, worked. That's why I trusted it and didn't export.
Now, in 2020 on Firefox/MacOS, didn't restore 48 tabs, but removed them from the list. Hours of work destroyed, no chance to know which 48 of ~ 1000 tabs were relevant to me.

Had the infinity Mark for over 100 tabs, and 'add all tabs to onetab' saved a grand total of TWO of them. Real useful. Beware, Android users.

Lost over 100 tabs on Firefox for Android. OneTab only saved… one tab: this very page. Why on Earth is this plugin marked as compatible for Firefox for Android?

DO NOT TRUST THIS EXTENSION. I've had it crash multiple times losing all my tabs on multiple different browsers and computers.

BEWARE! This add-on has closed all my tabs, and has populated only 2 out of the whole lot. I have lost all the tabs and there's no way to recover them.

Broken on Android! Beware! Only saves a few tabs (if lucky), I had 43 tabs, it only saved one. I tested again with twelve, and it only saved three. I was also unable to recover the lost tabs through 'recently closed' in history. Wonderful on PC, disastrous in Android.

No tengo.

Added OneTab, and it immediately closed all my tabs.
No tabs to restore.
No chance to get tabs back.
DO NOT INSTALL THIS ADD !!!

this app is broken and a risk to anyone who uses it provided you rely on it to 'save' your bookmarks. i had multiple pages saved to OneTab and one day it was all gone with no reason or explanation, and there is 0 support (completely ignored when I reached out for help, as I had some important links saved). Just bookmark what you need and give this broken app a miss!!

Closed out of all my open tabs, with no results. I used it on note 9 with firefox

The worst add-on I had on my system for months. Had the same running in Chrome, where it works quite well. On Firefox (72.01, 64 bit) win7 64 pro, it let me lose more than 250 tabs collected over a long time. Hope to retrieve them in my backups, but this add-on should be taken of the list immediately. One star is still one too many.
If the developers want to keep a small fraction of credibility, they should publish a method how to retrieve the lost tabs yet today.

Totally screwed my tabs and session on FF Android.
FU OneTab, specify if you know it's not working on Android.
