I have my Mozilla Firefox page tabs at the top of the screen running horizontally. Regardless how many tabs I may have open, the one that is currently being used (or far right) has just recently started showing Japanese lettering/words on both sides of the active tab itself. They are only on the active tab, none of the others have anything on them except search topic I may have on it. As I close out tabs, the Japanese lettering follows and will stay on both sides of which tab is currently being viewed.

Valittu ratkaisu

The McAfee SiteAdvisor extension has been reported to cause issues with text CJK (Chinese) appearing on tabs, so you can disable this extension.

I have removed the McAfee SiteAdvisor and the Japanese/Chinese sysmbols did go away from the tab section of current page. Thank you for the help.
