Trying to upload the themes created results in error messages: "This theme LWT alias is deprecated.

Warning: See https://mzl.la/2T11Lkc (MDN Docs) for more information."

A bit silly for it to have conflicts with the features it was intended for.

This is such a usefool tool, I love creating things so this is really fun! It's very easy to use and helps make great quality themes! :D

Works great, uses arcane wizardry to change your theme!

It's a shame that Personas has got retired.
Since I have Firefox Color my Firefox isn't working right anymore. It lags most of the time. Some pages (most of them are pages with shops, like amazon et al) aren't loading or crashing while loading. To avoid other reasons I tried it with several browsers (even the bad IE) and nowhere I have these errors I'm getting on Firefox since I'm using FF Color. And of course I tested it when FF Color was deactivated or removed. Then FF worked proper, like always before and with Personas. So after sending this review I'll say good-bye to it and will search for alternatives. FF Color is none!

Very Good!!!!
