How to make Firefox Portable work with ESET?

I have ESET installed and https filter option on.
When i use firefox it shows an error on every website:

Secure Connection Failed
An error occurred during a connection to www.xxx.com. PR_END_OF_FILE_ERROR

I've tried turn https filter option off and on. And imported the filter certificate of ESET to firefox but still dont work.
Does someone know how to solve this? Thanks
