I have been having trouble with some orders I have made online. The webmaster from one online store told me I should be regularly deleting the temporary Internet/cache files. Is this accurate? I know when I do this with Safari, some banking websites want me to enter my passwords again because they say I am using a compute that has not visited this website before. As far as my problem with ordering items online and having problems with the store getting my order, I was told by the webmaster that any good computer practice includes regularly deleting the temporary Internet/cache files. How do I do this on Firefox? I am new to using Firefox. Thanks!
