Thanks for the review. Would you mind adding the feature request in github issues of the project?

:-)

Thanks!

Thank you! 😀

Merci!

Thank you for a nice review!
You can drag an image from e.g. desktop onto a bookmark.

There is no fancy auto-generation of thumbnails or screenshotting or similar (only opera-like text based thumbnails) as there is no easy, independant of 3rd party services and secure way to achieve that in a firefox extension.

1. This is not a feature-request forum. There's a dedicated support page for things like that.
That said, you can easily do what you want in Settings/Custom CSS, enter this line:
body {background: #222 url("https://picsum.photos/1800/1200/?random") 0 0/cover no-repeat;}

2. Please understand, that I'm doing that for free, in my spare time, and you're not paying a cent for it. So I'd appreciate if you didn't put me down because in the free software that I gave you for free, I didn't include all the functionality that, I didn't know, that you wanted.
If you're looking for a feature that is not there, please add a feature request in project's github and I'll do my best to add it for you.

Thanks! :-)

Thank you!

Thanks, I think so too!

Thanks for the review.

Thanks! It was a pleasure!

Thanks for a great review!
Re favicons: no, not easily (https://github.com/tborychowski/perfect-home/issues/37#issuecomment-546635708).
I could only show 16x16px favicons, which would look ugly when resized to e.g. 128px.
I'm planning to show more than 1 letter though. Probably something like opera does in their speeddial. Stay tuned!
