Deleted all my tabs without saving, after new update, tabs do not show up in Onetab window. This problem is on Zen Browser

talk about Quality Of Life as an extension!! wow i love it

I've already loved this extension for years and just noticed there was a new update (2.13) and its so sexy 10/10. An elite extension for my purposes.

Deleted / removed all my tabs randomly, very frustrating. No firefox update happened, unsure if the addon updated itself, everything was gone from one day to the other.
Edit as a response to the dev: No other firefox extension data is affected, can you point me to where onetab stores its data?

Deleted all my tabs when firefox updated, thousands of tabs. When I reached out to support they gave me info for chrome.
RE: Developer response
I do not have "system cleaner" or "privacy cleaner" software installed. This is quite frankly a cop out. Your product sucks and you know it.

Thanks for finally making it work again. I wonder how long I can use it for until it breaks again?

I REALLY want to downgrade. I don't need the fancy ui... it takes way more clicks to do all the simple things I needed to do. Is there an xpi file or something of the old version? I need alternatives asap. Cool new features... but I don't want to click four times to do something that used to take one or two clicks.... that's bad ui design.

Terribly slow since the update, what is going on?

Simply ingenious, I can have tons of tabs open and get back to them later without it taking up memory or creating clutter in my space. The new update is great, it's like tabs for my tabs instead of a list now. I feel like I'll never get bored or lose track of something that I want to get back to, and it's not going to create clutter I don't want to lose or keep forever in my bookmarks.

Super handy extension! Especially when doing research or looking for references. Once you feel like you need a break you can wrap everything up with a single click and not worry about losing track or spending tons of time bookmarking tabs one by one. (One thing I'm missing though is ability to merge groups on android but it's not worthy of removing a star :P)

VERY VERY often this completely breaks and deletes ALL tabs saved in it. When it works it works amazingly, until it decides everything youve saved is now made of ghosts and clears itself to fresh install status but with settings the same

I used to exclusively use this but i just cant rely on it whatsoever now

Edit for you guys: If it is firefox doing this, ive gotten no warning or refresh firefox indicators at all and i have auto updates off so im not sure wth is going on here, will be changing my 2 stars to 5 because of this information because it really is the most useful tab storage add on with easy as heck wyas to mass save tabs

Love Onetab, but not a fan of the most recent update. Not sure why they changed it to this forced center-aligned layout with no ability to change it to something like previous versions, but it makes for a ton of wasted space on either side on my 1440p monitor. I also have the bug with Onetab auto-pinning its own tab every time it opens but they've mentioned they'll fix that soon, at least. Reverted to an older version for now.

1. If any application (including browser addons) does not have an OFFLINE import-export-backup function, it has no value to me, does not follow good practices and is poorly designed.

2. Cloud sync may be OPTIONAL for users who clearly need it.
Full import-export (containing complete data to restore the previous state, folders, groups, stars, pins, tasks, etc.) locally to the file is the foundation.
Cloud here, cloud there, some clouds everywhere, but a large group of users do not use clouds for everything (many use self-hosted) and must have access to file backup.

3. Currently, it is not possible to return to v1 as a workaround -> v2 should not be released because it is incomplete.

4. Do not install v2 if you plan to reinstall the OS soon, because you will lose the ability to export your OneTab bookmarks!
I was going to install a new OS in the coming days and now I can't transfer my bookmarks.

Maybe need to look for another addon?

PS: The current look and new features are great, but the lack of FULL file export-import is a bummer...

Newest update wiped years of accumulated tabs. The developer has taken no responsibility. Changed the way they save tabs, don't test it, and wipe user's existing tabs without making a backup first?

DO NOT TRUST these developers.

Doesn't work in TOR version 15.0.8 (based on Mozilla Firefox 140.9.0esr)Thanks for the reply, I'll use Sidebery.
