Install this add-ons to block the ads: https://addons.mozilla.org/en-US/firefox/addon/adblock-plus/ When you see the option to subscribe to "Easylist" during the installation process, click OK. After you restart Firefox, go to the Adblock Plus subscriptions page here: https://adblockplus.org/en/subscriptions Scroll down to the bottom of the page and in the section called "Miscellaneous", subscribe to this one as well: "Malware Domains". This will afford you additional protection against malware. I have a friend in Thailand who has an NC10 and in spite of the fact he only has a 2G Aircard, the performance of which is abysmal, he doesn't experience any problem loading sites with Adblock Plus installed.
