I've gotten annoyed enough to just copy the source from most of my extensions (located at `~/.config/google-chrome/Default/Extensions/`), remove the update stuff from the `metadata.json` and load them as developer extensions so they never update.

It's easy enough to update them + audit the code when something breaks. The hardest part is downloading the new code (.crx) without installing it, I had to write javascript I paste into the console. StackOverflow can unzip a crx by striping the first 306 bytes.

I forked Stylish v1.5.2 a year ago before I heared of Stylus, but I've no need to to switch since the original extension was pretty good. https://github.com/Zren/chrome-extension-stylish#fork
