I wanted to share a Firefox 4 tweak I recently found over on the CNET Download Blog. This particular tweak tells Firefox how to handle lots of open tabs. There is a little bit more going on but basically this feature tells Firefox not to load tabs until you need them.  This is very useful if you tend to leave a large number of tabs open. To get started you’ll need to grab a copy of Firefox 4. Once you’ve installed/updated Firefox, start the browser and type “about:config” (no quotes) into the address bar and press enter. You’ll need to press the “I’ll be careful I promise!” button. Type or paste: “browser.sessionstore.max_concurrent_tabs” (again no quotes).  Next double click on browser.sessionstore.max_concurrent_tabs and change the value to 0 (zero). Press OK and restart Firefox. You’re all set. Firefox will now only load your tabs when you need them.

If you want to stick with an older version of Firefox or aren’t comfortable editing things in about config, the BarTab Firefox addon performs a similar tweak to tabs in Firefox.

Works where ever Firefox does (Mac/Win/Linux)
