I am able to type a web address and use the internet successfully but when using ANY search engine I get the '500 internal server error' message. This appears if I type in a word to search bold textand the result is the error message. I have recently uninstalled rapport and hitman pro. Please help.

Did you check your security software (firewall)?

Which security software (firewall) do you have?

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
