Is there any limit in the number of firefox profiles that can be created?

My issue is I am currently doing selenium webdriver automation in linux for a device. There are 50 devices of same kind and framework will pickup a device depending on availability. I need to by pass unsigned ssl pages. I am using firefox 14.

I have implemented following but it is not consistent.

everytime a device is chosen adds cer of device to the cert file in firefox profile but I am getting sec_error_bad_signature very frequently.

So I started recreating cert [delete and create if by opening firefox] file for every run.

Now this is posing a problem if multiple devices are run at the same time. Hence I want to create separate firefox profile
