The developer doesn’t know what a web address might look like, but puts fancy rules. Half of URL addresses cannot even be added because of "Error: Valid URL is required!". Even though website preview is working.

Спасибо, годится!

It could've been great, but is not. Obviously in the development of this addon is missing the contribution of a UX/UI and a software analyst.
Several issues like:
- the pages do not show in the bookmarks, and that is the only way to export them when reinstalling, wich make it unusable for me.
- tiles are static and non responsive design was used
- the preview is a bad bad idea, it should have been just as an option or button... UI is missing
- tiles cannot be added offline
- slow/useless animation
- unfriendly and unprofessional aspect in the same time
- painfully ugly icon that does not work with any theme...
- trying to promote a certain search engine... they probably paid.
- etc, etc.

It could have been brilliant, I would have paid for a good extension.

So far so good, I like the simplicity of it, but one of the problems is the search engine, it is 2020, no one uses Yahoo so please change to Google or at least give the users an option to choose their preferable search site.
