Firefox Hack: Control Tab Scrolling

Tabbed browsing is a blessing and a curse. Sure, you have easy access to several sites. But if you open too many tabs at once, Firefox 2 will shrink them, then scroll the others off-screen. ..

If you want to see all your tabs, change the tab width or turn off the scrolling feature completely. Type about:config in the address bar and choose the browser.tabs.tabMinWidth key. The default value is 100, meaning that the minimum width of a tab is 100 pixels. You can modify this number—double-click on the value—to fit more tabs in the screen before the scrolling kicks in, or just enter 0 to disable the feature entirely.
