After reinstalling Firefox getting FireFTP error message "gSiteManager is undefined”

[Cooper Sheldon]

I just updated my computer to Windows 7 and installed Firefox 15 on it. After installing, I logged into my Gmail account. I entered the username and password and then clicked on the remember me checkbox. I was able to log in the account properly for the first time. But the next time, I tried to access Gmail, I got an error message that said "gSiteManager is undefined”. I checked on internet it was described as FireFTP error message. I first thought that it must be some problem with Gmail. So I tried it on Facebook and again same problem. There was no such problem in Google Chrome. Can someone tell me how to solve this problem?

I too got this same problem few days back and I think that this is some bug present in Firefox 15. I found an way through to get past this problem. I found a URL which you will need to click using Mozilla Firefox 15. Once you click on it, a file by name fireftp-2.0.4-fx.xpi will be downloaded. This will solve the problem.
