Firefox Hack: Turn Off Tab Scrolling

If you tend to open a lot of tabs in your Firefox browser, then you know that when you get too many open, you end up having to scroll to see the tabs that have gone off-screen. I’ve had enough of this, so I found a way to turn off the scrolling feature altogether. In the address bar, type about:config and choose the browser.tabs.tabMinWidth key. The default value is 100, which means the minimum width of a tab is 100 pixels. You can modify this number, so the tabs get smaller, which would allow for more on the screen before the scrolling feature kicks in. But if you want to disable scrolling, you enter 0 to turn the feature off entirely.
