I really like this add-on, it's very handful for some things and I like the visual style and the many customization options it have.
But I have to say that there is a little problem: The Tabliss add-on is returning to its original state after a little period of time. Sometimes minutes, sometimes hours.
Because of that, I saved my configuration on my PC and have to import it often.
If were not for this issue, this add-on surely have 5-stars by my side.

Very cool stuff, but once in a wile I loose all my widgets, any clue why that happens?

Great add on but one problem after i have set up my tab with the widgets and the links in them a few weeks later it just reverted back to the default Tab

even thouhg it was working in sync accress all my devices

It's really nice extension, best extension of its type. Very customizable. Except, there's a problem. After a few days, all of the customization reverts back. Everything reverts back. It's really annoying, since I also did a lot of CSS customization.

Disconnect extension not loading

Tabliss can be customized in so many ways - from the background images to custom CSS! I'm really enjoying this 'New Tab Page' add-on.

Deberia permitir cambiar el tamaño de la fuente para cada widget

I like this extension. Its great to me. It would have far better if it had a setting for displaying custom sites at the bottom.
