As of February 2019, Firefox is the main web browser I use. I find it slower than Google Chrome (which I use for Facebook, Messenger, Gmail, and YouTube), but find its address bar more useful.


Due to the Firefox 57 upgrade, several of the plugins I used to use were marked as “Legacy” and are not usable. In particular, NoScript was at first unavailable, then available under the new extensions system in a new form. I didn’t like the new interface so I switched to uMatrix.

I have several custom keyword searches on Firefox. Following DuckDuckGo’s idea of “bang expressions”, I prefix each keyword with ! (even though I don’t use DuckDuckGo).

Note that for the Internet Archive keyword searches, use %S rather than %s for the search string placeholder. The latter URL-encodes the search string while the former doesn’t.

I used to use bookmarklets, but have since switched to using an addon (for citation generation) and keyword searches (for accessing websites).
