Hi! Welcome to our little antiX “family”.
any problem you have, feel free to post about it and someone will try to help you out (dig through the forum posts first- we have lots of good info and tips available).
antiX 19 runs great and it is also, I believe, the best looking and more polished antiX version to date (and for sure the best looking distro considering the ratio of “features and looks”/”resources” used).
I’m not sure how much RAM you Hp has- if it’s 1 Gig of RAM you’ll probably be better off using a lighter browser than Firefox for “heavy” browsing- or else take care not to open many tabs at once. Other than that- antiX runs like a champ on my single core atom netbook with 1 Gig of ram, so it should behave even better, even in most of “old” computers…
