Random Firefox Tweaks

The following options have to be changed or added in about:config. Those tweaks can of course be achieved through extensions, but by setting them directly you can abandon some extensions and hopefully conserve some memory.

In order to open a bookmark-folder with mid-click in tabs without overwriting the current tabs change:

browser.tabs.loadFolderAndReplace=false

To remove the close buttons on the tabs (they still can be closed by mid-clicking on them):

browser.tabs.closeButtons=2

Enable the spellchecker for inputfields and textareas (default is textareas only):

layout.spellcheckDefault=2

To override the useragent string:

general.useragent.override=foobrowser

And the last one really made my day: Open lastfm://-links directly in amarok:
network.protocol-handler.app.lastfm=amarok network.protocol-handler.external.lastfm=true

BTW: Shouldn't firef*cough* iceweasel open the composer of your mailclient when clicking on mailto-links?
