Walter Pratt (ID: 0000004190dadbcc) Voted 1 ★ - Updated 08/31/2022 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.

Vlad Tyum (ID: 0000007bba79d24f) Voted 5 ★ - Updated 10/02/2019 Rudie, thank you very much for the extension. Yet accounting an issue. Nowadays it changes fonts to limited list like Arial, Verdana. Could you please add "Default" option?

David (ID: 00000075bdbd43fb) Voted 5 ★ - Updated 02/26/2019 Fantastic way to fix unreadable fonts on websites. Finally, I can get clear, unaliased, sans serif fonts without resorting to a reader app (Pocket/Instapaper/Mercury). Interface is very simple and each website is permanently fixed.
