awesome replacement for stylish!!! and the one that keeps compatibility with firefox 52 and windows xp (this is my grandpa's pc and it's too old for windows 7 onwards)
please don't ever sell our information

- PS: for the people looking for custom and/or dark firefox options and about pages just install a theme that changes that, I have FT Deep Dark theme and "my favolours" style for a dark and non-eyehurting web experience
- PS2: One thing I liked from old stylish is that it had omnipresent application of global themes. With stylus sometimes is visible a white screen for a second after clicking a link. Also sites like this one and firefox start page are not included in stylus for global themes. If you could fix that it would be awesome. Thanks for your work
