Can't log into certain sites using Mozilla

[vertigo21]

I am using the latest version of Firefox and it will not allow me to log into certain sites that I am regitered for. This problem boggles me because it allows me to log into some sites but not others. What is the problem?

There can be two problems that I know of one would be that one of the security tools that comes with firefox will automaticly block sites it determines to be bad the second is your packet size. Rescently some companies have reduced the size of the packet your computer must send in order to log in for security reasons try adjucting your packets and see if that helps.

Another possibility is that they use plug-ins which work in IE, but not Firefox. (Another Microsift monopoly ploy?)
