A tiny Firefox addon
Back when I used Notion daily, what really annoyed me (besides no Vim keybindings) was that the app’s favicon was dynamic. It changed to match the icon of whatever page you had open which might be nice for some people but it kept confusing me.
So in 2022 I built and published Static Notion Favicon, a Firefox addon that does exactly one thing: it keeps the tab’s favicon pinned to the default Notion icon, no matter which page is open. If you want, you can point it at a custom favicon URL in the settings instead.
The source code is on GitHub although there isn’t really anything to see there. It really is tiny :)
