Firefox Community Forum

Hi. I installed Firefox on my old Hp, and have now taken another laptop, an Acer Aspire One and installed Firefox on that as well, but a extended support version. I am struggling to import all my bookmarks (ex Chrome) to my Acer, and in the struggle I done something wrong since Firefox on the Acer is now locked or blocked !! I am an "old Timer" and not very computer literate. Can someone help me solve these issues so that I can move away from the HP and depend on the Acer. I found Firefox easier to use as compared to Chrome, which seemingly demanded more memory from the computer.

I need to know where to go on Firefox to clear my cookies. I'm having trouble completing purchases using PayPal. When I go from PayPal back to the shop to complete the purchase, it will not pay to complete. PayPal says all is okay on their end. One person suggested clearing my cookies, but I don't know how to do that. Please help if possible. Thank you!
