My favourite firefox extensions

Add-ons

Tips and tricks

In about:config

keyword.URL = http://www.google.com/search?hl=en&q=   (No longer works)
keyword.enabled = true
browser.tabs.loadDivertedInBackground = true - Don't focus the web browser when clicking on a link in your RSS reader etc.
dom.disable_window_move_resize = true
browser.newtab.url = about:blank - Instead of the default about:newtab
browser.tabs.closeWindowWithLastTab = false
extensions.checkCompatibility.17.0 = false - Enable add-ons marked as incompatible. Replace 17.0 with the current Firefox version.
security.mixed_content.block_display_content = true - Block e.g. HTTP images on HTTPS sites. I think HTTP javascript is always blocked.
ui.key.menuAccessKeyFocuses = false - Alt key alone does nothing, Alt-F shows file menu, etc.
reader.parse-on-load.enabled = false - Remove Reader View icon from URL bar.
browser.urlbar.suggest.openpage = false - Don't suggest "switch to tab" in URL bar.
browser.sessionstore.restore_on_demand = false - Load pages when starting Firefox, don't wait until the tab is selected.
security.dialog_enable_delay = 500 - Wait less before enabling OK button on open file dialog (the delay is a security feature!)
