I have the same problem like other users.

so I build an alternative, because I have been struggled for a long time.

It's Link Map, and open source on Github, supporting import from Tabs Outliner.

It's available on:

Chrome Web Store

Edge Web Store

Hello Vladyslav,

I was a premium user of Tabs Outliner a few years back. I very much liked its hierarchical tree model and browser control. Particularly for that point in time it was a very nice piece of work.

Recently I've been developing a quite different tool but with a similar tree structured data model and ability to control the browser. I've been focusing on building not marketing but have generated some enthusiastic support from users even in advance of the 1.0 version. I had some TO users request imports into BrainTool, my extension, so I implemented an ability to do that.

From surveying the activity on the Google Group and userecho site it seems like the Tabs Outliner project is somewhat moribund, but with a number of active and often frustrated users. As you probably know Tabs Outliner will stop working at the end of the year. I think BrainTool is a good match for those peoples needs and having them as users might enable it to evolve faster than it would otherwise.

Are you interested in open sourcing or selling Tabs Outliner? I would like to offer a migration path to BrainTool and the potential for the TO source code to be ported to Manifest V3 such that it can continue to work in 2023.

Thanks for your consideration,

Tony Confrey

Gives 404 error

https://chrome.google.com/webstore/detail/tabs-outliner/eggkanocgddhmamlbiijnphhppkpkmkl

My tabs outliner extension crashed (chrome said it was corrupt). When I repaired the extension, i was logged out of my account, with no way of logging back in. The crash caused me to lose my current list of tabs, and I cannot restore my backups without having a paid version activated, but I can't login to my paid version! Please help!!

I get this error

 The duplicate entries have no text next to them and a spinning loading circle when the tab is open. Is this a known bug? Example:

hello, thank your for designing/building this amazing extension. not long after using it I decided to buy the donation key version for the added benefits and to support your work. Although I realize there is/was/were no claims that it would work with any browser, I tried and discovered that Tabs Outliner DOES work with the Vivaldi web browser. to an extent. The only problem is when trying to verify that I have the paid upgrade,I am required to sign into Chrome, and when I click that button, I get this web address: "vivaldi://chrome-signin/?access_point=6&reason=0". Is there some kind of workaround I can use to get my account/paid status verified? Thanks so much in advance.

I paid a licence for my first gmail account I use daily and according to this thread -> https://groups.google.com/forum/#!msg/tabs-outliner-support-group/qIY2Z7SP-PA/iyWVtQlFAAAJ if you buy you can link other account... this is a LIE the support@ email doesnt work, nobody will answer you even if you pay. Even though, I decided to buy a second Licence for my other Gmail account, unluckily I mistyped the correct email address (and it submitted the pay anyway) so after the purchase of my 2nd licence I didnt got NOTHING and I LOST MY MONEY... I already paid this people 30USD (for 2 licences) for this tool... no answer to anything even after months.... I still dont have my second account activated (even when i paid for each account!!)... nobody gives an answer.... this guy seems to be dead, his last post here is from 4 years ago... none of the features he said he would do, aren't even close to done after more than 4 years... no sync between chrome sessions at all, and I doubt this people does pay attention to this or anyone at all..... who gets the money from this??? who takes responsability??? I even wrote the people of fastspring, but even them dont give even a refund for something I BOUGHT; IT DONT WORK, AND YOU DONT HAVE SUPPORT FOR ANYTHING..... DONT BUY FROM THESE DEVELOPERS, they are no serious nor professionals nor polite nor good to do anything with them.... be aware!!

TO is an awesome Chrome extension (by far my favorite) and I was wondering if you were planning some way to sync it to mobile devices so that I could continue with the tabs I have on the go. That'd be an awesome feature!
