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.
