This is actually a useful tool, I myself have been using the "Count me up lite" extension for a long time, but now, due to the new update of Google Chrome, it is no longer possible to use it. There, if you select the text of any web page and click the right mouse button, the extension used to show the character count separately.
But currently I can't find any other extension like that.

Anyway, Royal Cap brother, this extension of yours will be more useful when other people's posts characters won't be count I mean including and inside the "quote".

Code: [quote]....text.....[/quote]

For example, it is already showing 1127 characters even I didn't put a single character.
