This extension has improved a lot over time. It used to break websites by making web elements & text clash, making it illegible, but this is very uncommon now. It's also ridiculously easy to disable the extension on a site-by-site basis if needed/desired.

I love what it does in general and I love what it did with ao3 however it screws with my tumblr and the appearance of it so I decided to uninstall if it stops effecting my tumblr I would go back

Sending crap back to their servers.

excellent

Couldn't ask for an easier and faster way to not get flashbanged all the time
