I get this error after I have already installed something, but I try to install it again cause it's effects are there as are it's existence in the scripts list... I don't know where to find the .js file to delete it cause I'm on a Mac, and I don't know Mac's that well... Here is the error message.

[Exception... “Component returned failure code: 0x80520008 (NS_E RROR_FILE_ALREADY_EXISTS) [nsILocalFile.copyTo]” nsresult: “0x80520008 (NS_E RROR_FILE_ALREADY_EXISTS)” location: “JS frame :: chrome: //greasemonkey /content/config.js :: anonymous :: line 148” data: no]

Anyone.. ??? There has to be more than one person (and the other guy that posted about this, that no one responded to) that is having this problem.

This has been brought up a more than once on this forum (see eg. here, here, and here), and the general solution seems to be to delete the script source from your "gm_scripts" folder in your firefox profile folder and try again.

If you also want to see other solutions, you could also try looking on the mailing list (example search here).

Note that this forum is mainly intended for script development/use. The mailing list is a better bet to get help with issues with the extension.

I just had this very same thing happen with one of my new scripts....I knew it had to be something inside firefox because only one of my machines was affected. Found the dir. and deleted the script, then reinstalled...woila!
