Firefox about:config

This is a post mainly for my future reference. I may edit it as I learn new things. Feel free to ignore.

• Full list
• browser.startup.page - Page to open on browser startup. 0: Blank, 1 (default) Home (a.k.a. browser.startup.homepage), 2: Last (probably does not work)
• browser.block.target_new_window - True: Links with target set to _blank will open in the current tab instead of a new window. False: Links with target set to _blank will open in a new window. Note: No longer in use. Use browser.link.open_newwindow instead.
• browser.link.open_newwindow.restriction - 0 (default): Force all new windows opened by Javascript into tabs. 1: Let all windows opened by Javascript open in new windows. (Default behavior in IE.) 2: Catch new windows opened by Javascript that do not have window attribute values set; otherwise allow them to open a new window.
