Useful settings in Firefox 2.0

Here are a few settings that I've changed in my installation of Firefox 2.0:

browser.tabs.closeButtons
Default value: 1
New value: 3
Effect: The close tab X button will appear only on the far right of the tab bar instead of every tab. Setting this value to 2 will show the X button only on the currently selected tab.

browser.search.openintab
Default value: false
New value: true
Effect: Searches made with the search box in the upper right corner of the window will now open in a new tab instead of the current one.

browser.tabs.loadFolderAndReplace
Default value: true
New value: false
Effect: Selecting "Open All in Tabs" from a folder in your bookmarks will no longer close all currently open tabs.

These settings can be changed by entering "about:config" in the address bar.
