Alex over at Lifespy is a big fan of tabbed browsing (as am I), but he’s not into the scrolling tabs so much. If you share his displeasure with scrolling tabs, you may find the following Tab Scrolling Tweak interesting.

• Open the about:config page
• Find the key browser.tabs.tabMinWidth
• To allow smaller tab widths before scrolling, you can set the number to a smaller number
• To disable the feature, set it to 0
• Close the page
