For context: I read the thread about startssl. I already have in the past a problem with firefox and startssl certificates.
At the moment i have two customers in cpanel who need ssl, and was thinking in use positivessl certificates (9.95 usd ones) , and some questions arise for me.
1 ) Have u experience with that certificates ?
2 ) is better Linux or windows account?
Thanks in advance
They work fine 
BTW i have startssl on https://helpdesk.jodovps.com and use it daily without issue, give it a try?
My customer have in the past some problems with startssl (tradicion.net) under firefox and dont want startssl more. =(
Then the friday, i purchase the two positive ssl, and seek u. I assume linux is ok.
Linux or windows is ok, my personal preference is Windows for obvious reason
