Mozilla Firefox - on Ubuntu

Firefox comes pre-installed on Ubuntu. Here are some useful customizations.

1. (optional) Some useful extensions:
   • Google Browser Sync - access your bookmarks from anywhere.
   • Forecastfox l10n - show the weather forecast in the status bar.
   • SearchWP - quickly search for words in the search box within the current page.
   • SearchBox Sync - synchronize Firefox's search box with those of search pages.
   • Searchbar Autosizer - grow the search box to fit the search query as you type.
   • Context Search - search for the currently selected text.
   • DownloadThemAll! - download all files of a given type on a page.
   • lget - download from a specified URL.
   • Linkification - intelligently recognize plain-text URLs as links.
   • CustomizeGoogle - customize some features of Google's search pages.
   • Image Zoom - self-explanatory.
   • Web Developer - useful for creating and testing web pages.
2. (optional) Enter about:config in the URL bar and then make the following changes:

   general.autoScroll=true
   network.http.pipelining=true
   network.prefetch-next=false
   browser.backspace_action=0
   browser.link.open_newwindow=3 (3: new tab; 2: new indow; 1: current tab)
   browser.link.open_newwindow.restriction=2 (0: use open_newwindow setting; 1: new window; 2: use open_newwindow setting unless javascript specifies window size)
   browser.search.openintab=true
   browser.tabs.autoHide=false
   browser.tabs.closeButtons=2
   browser.tabs.loadFolderAndReplace=false
   browser.tabs.loadGroup=0
   browser.tabs.warnOnClose=false
   browser.search.minwidth=300
   linkification.settings.Linkify_OpenInTab=true
   linkification.settings.Linkify_OpenTabinBG=true
   linkification.settings.Linkify_Toggle=false
   

3. (optional) Open URLs entered in address bar in a new tab by default. (Useful if you hate having to press ALT+ENTER to achieve this.) Note that the following needs to be done each time a new version of Firefox is installed (e.g., as an Ubuntu update).

   sudo apt-get install fastjar
   pushd /tmp; fastjar -xf /usr/share/firefox/chrome/browser.jar content/browser/browser.js; popd
   sed -i -e"s/if (aTriggeringEvent \&\& aTriggeringEvent.altKey)/if (!(aTriggeringEvent \&\& aTriggeringEvent.altKey))/" /tmp/content/browser/browser.js
   sudo fastjar -uf0 /usr/share/firefox/chrome/browser.jar -C/tmp content/browser/browser.js
