The Last.fm Debloater door 54ac

I wrote this addon primarily for myself, but I figured I might as well share it with the other four people who still use Last.fm. Turn it on and leave it be or untick some checkboxes if you want, depending on what suits your fancy.

List of available options:
Artist – Title song format in charts
Square avatars/artist images
Remove image borders
Compact rows in charts
Compact artist header
Change color of scrobble bar in charts
Invert scrobble bar font color
Remove main font
Black text
Regular font weight for song titles/artists
Increase font size
Remove descriptors from scrobble bar
Use absolute timestamps
Fit main column to page width
More space for top track title

Most of the other unwanted elements (Spotify integration, ads, videos, etc.) can be removed using uBlock.
