You shouldn't use Firefox 3.6. You should talk to your company's IT department. Firefox 3.6 has not received an update in nearly a year, and is horribly insecure. Using it on your company network not only leaves your information insecure and up for grabs, it leaves the whole network vulnerable. If you'd like you can have your IT department talk with me about the situation :)

hello, please use a portable version of firefox 3.6.28 for the tasks which require such ancient software but stick with the current firefox for all other browsing, since there are many known security vulnerabilities in older versions that will put the system & all data on it at risk.
