Do you like it or hate it when Firefox decides to give you the left and right scroll buttons up on your tab bar to navigate through a long list of tabs?
Minimum Tab Width
One way of fixing this would be going into your about:config file and bumping down the minimum tab width so that more tabs fit in the bar before the scroll scroll feature starts. Your default limit is 100 pixels but you can set it to what you need.
Open up about:config (by typing the phrase into your address bar) and search for this string in the search box provided at the top:
browser.tabs.tabMinWidth
Change the default to whatever you might want it to be. If you set it to 0, it will disable tab scrolling.
Delete the “Close” Button on the Tabs
Now while we are saving space, why not get rid of the close buttons that appear on each tab? To get this done search the about:config page for:
browser.tabs.closeButtons
Set the value to “2″ and ditch the close button all together. A value of “0″ only displays the close button on the active tab, “1″ (the default) shows it on all tabs. Now you have a little more power over your Firefox tabs.
