''My tabs no longer have the close "x" icon on the right of each tab...'' I have mine set to only show at the far right of the tabs bar and it only applies to the active tab (to restore pre Firefox 2 behavior). The setting is in [http://kb.mozillazine.org/About:config_entries about:config], but you may have an extension or perhaps a theme or a style that is changing it. '''browser.tabs.closeButtons''' Integer (Firefox 2.0 and above) This preference controls how close buttons can be displayed on tabs. :0: Display a close button on the active tab only :1: (default) Display a close button on each tab :2: Don't display any close buttons :3: Display a single close button at the end of the tab bar (Firefox 1.x behavior) Tabs Mix Plus would be the most likely extension if an extension were involved, it has its own settings. ''I can only close individual tabs by right clicking on tab then closing it that way...'' Besides the right-click context menu, you can also close a tab with a keyboard shortcut ("Ctrl+W"). * Firefox Support Home Page | Firefox Help<br>Adapts to your system, but a very limited number of shortcuts are shown<br>https://support.mozilla.com/kb/Keyboard%20shortcuts * Firefox and other Browser Keyboard Shortcuts (Comparison Table)<br>Long list of shortcuts -- Windows oriented, most other systems use similar (Mac/Linux see key at top) <br>http://dmcritchie.mvps.org/firefox/keyboard.htm

Thanks, I ended up reloading Firefox and it is corrected. Must have been something on my computer that was affecting it.
