hi! i am not being able to open firefox. i get a message that it is already open and i must close it first. when i close it and try to open it i get the same thing. i am able to use internet explorer but at the bottom of the page it says: done, but with errors on page. things do seem a little slow also. any ideas? i am pretty basic on my computer knowledge. no tech skills to speak of. i do have virus protection and antispyware protection. both are updated and current. thanks for reading and any help you can offer!
