Since downloading Firefox update yesterday, the language/script in which window/tab titles are displayed is not English. Everything else is in English (how I like it).
The language/script in which window/tab titles (e.g. "Mozilla Homepage", "Google", "Amazon.co.uk" etc.) are displayed is not English, but an oriental language. Everything else is in English (how I like it). I cannot find anything in the tools/options menu to fix this (not that I think it is the result of anything I have done!).
This happened
Every time Firefox opened
== I downloaded your update (3.6.4) the other day.

If you see CJK (Chinese/Japanese) characters on the Firefox title bar or the Windows Taskbar then that can happen if Firefox switches to UTF-16 encoding for some reason.
The RealPlayer Browser Record Plugin extension (Tools > Add-ons > Extensions) has been reported to cause that issue.
Be sure not to get confused with the RealPlayer plugin (Tools > Add-ons > Plugins) that plays media files. The extension adds some extra features like saving media files.
You can disable/remove the RealPlayer Browser Record Plugin extension in the RealPlayer Preferences (RealPlayer: Tools > Preferences > Download & Recording)
