Addons that I sometimes like to install:

- https://addons.mozilla.org/en-US/firefox/addon/textplain/ - Firefox 4 and up has this built-in.

guandgU. - https://addons.mozilla.org/en-US/firefox/addon/firebug/ - but normally I have this disabled unless I need it.
- https://addons.mozilla.org/en-US/firefox/addon/downthemall/ - good when it's needed, but I don't use it much. Usually disabled.
