Tweaks

• Turn off domain guessing (which adds www. and .com) for link URLs
  • browser.fixup.alternate.enabled false

• Display the alt-text instead of the "image-not-found" image
  • true will force ALT text for missing images to be layed out inline
  • browser.display.force_inline_alttext true

• Keywords
  • These allow you to type things in the location bar, like wp some phrase and search Wikipedia for 'some phrase'. To implement this:
    • Create a bookmark.
    • Keyword: wp
    • Location: https://wikipedia.org/wiki/Special:Search?search=%s&go=go

Old notes

• [2] [3] scrolling transaction - I could remove most of the annoyance of scrolling the whole page when scrolling just one element.
  • mousewheel.transaction.timeout

Some of these notes could be as old or older than 1.5. Technically I've grandfathered everything here into the latest Firefox.

• Stop those damned images when dragging tabs. FINALLY it also fixes the annoying crap covering your mouse when you drag-and-drop bookmarks.
  • Serious speed improvement.
  • nglayout.enable_drag_images false

• [4] Use XBL form controls
  • Don't use website-based form theming, use browser/OS-based theming. Performance increase.
  • nglayout.debug.enable_xbl_forms true

• [5] Safe Browsing - I don't need this feature, and I don't want to waste CPU cycles, memory and disk space on a lookup file.
  • browser.safebrowsing.enabled false

• Present the normal Ok and Cancel buttons on the preference screen.
  • browser.preferences.instantApply false

• Don't animate when switching preference panels. Important on Mac.
  • browser.preferences.animateFadeIn false

• Delete temporary files on exit. Umm. Yes, actually make the temporary files TEMPORARY.
  • browser.helperApps.deleteTempFileOnExit true

• [6] Resized images
  • browser.enable_automatic_image_resizing false

• Paste with the middle mouse click. This would be important on non-Linux.
  • middlemouse.paste true

• [7] Stop trying to paste the clipboard as a URL
  • middlemouse.contentLoadURL false

• [8] Disable the "Download Complete" popup that appears at the bottom-right when all downloads are complete. It's slow to animate, overrides important stuff and is a complete pain in the ass when the system is under heavy load. It's also completely pointless when I queue many downloads and I have to come back to over 9,000 save dialogs.
  • browser.download.manager.showAlertOnComplete false

• [9] Untrustworthy default. Change it so that only cookies from the originating server are allowed
  • network.cookie.cookieBehavior 1

• ~ [10] Stop that damned delay when interacting with popups like save dialogs.
  • security.dialog_enable_delay 0

• [11] Don't pre-fetch content, such as when googling which pre-fetches the search results. Damn that's stupid.
  • network.prefetch-next false

• [12] Show tooltips for toolbar buttons, bookmarks, web content, and other items.
  • browser.chrome.toolbar_tips false

• [13] Spell checking in all fields including one-line fields.
  • layout.spellcheckDefault 2

• [14] alt-home homepage
  • browser.startup.homepage http://google.com
  • [15] browser.startup.page 1

• [16] typing in the location bar searches.
  • keyword.URL http://www.google.com/search?ie=UTF-8&oe=UTF-8&sourceid=navclient&gfns=0&q=
  • keyword.URL https://ssl.scroogle.org/cgi-bin/nbbwssl.cgi?Gw=
  • Now right_click beside the top location bar > customize. Drag the top "search" area into the middle area and drop it.

• [17] If there's just one tab, don't hide it. Press F11 if you particularly need full-screen.
  • browser.tabs.autoHide false
