Font Blocker: Control Your Viewing Experience

"Font blocker" is a Chrome extension that empowers users to refine their web browsing experience by blocking custom fonts that they find annoying or disruptive. It does this by adding the identified font to a local database, which is immediately blocked. Features include the ability to block fonts globally, across all websites, and mark fonts for blocking or unblocking. It also provides compatibility for Firefox through WebExtensions. Version updates offer continual improvements for an innovative browsing experience.

Issues: 1) replaces to Arial!!! My eyes are bleeding. Should better have a user-configured default sans font; 2) replaces monospaced to Arial!!! My eyes are bleeding. Should better have a user-configured default monospace font; 3) replaces serif to Arial!!! My eyes are bleeding. Should better have a user-configured default serif font. 4) Probably breaks font metrics, so on-line editors misplace text caret. For me it's definitely broken. Otherwise extension is working good, it really makes all those mad designers to behaviour nice. But with 1-4 problems, this extension is useless.
