extension - This is code for the Chrome/Chromium extension.
stackinbox-for-firefox - This is the code for the Firefox extension.
userscript - Originally, I tried writing as a userscript, but I wasn't able to sync with all *.stackexchange.com domains, so I converted to individual browser add-ons. This is here for historical references.
