As the Internet goes slower and slower and your Internet Service Provider refuses to go faster and faster, these are three easy things you can do to speed up Mozilla Firefox:
1. Disable IPv6
For a regular web page such as slashdot.org, Firefox needs to resolve more than 40 domain names. Each domain name is resolved twice, once for an IPv4 address and once for an IPv6 address. This results in lots of DNS requests, slowing down your web access. If you are like 99.999% of the population without IPv6 access, translating domain names in IPv6 addresses is useless.
To disable this functionality, type about:config into the address bar. Type ipv6 into the search bar and toggle network.dns.disableIPv6 to true.
2. Install Adblock Plus extension
The extension will cut down most, if not all, advertisements and annoying banners.
3. Install Ghostery extension
The extension removes “invisible” trackers, web bugs, pixels, and beacons placed on web pages by Facebook, Google Analytics, and over 1,000 other ad networks.
