Bluhell Firewall for Firefox works for both PCs and Androids and is the simplest ad blocker available. It takes up less space that other ad blockers, as the download is just 30KB. By comparison, the downloads for other ad blockers are usually around 700KB. The small size lies in the fact that it uses just seven blocking rules that can be used on roughly 8400 .net and .com domains. The application of these rules enables the extension to work quickly rather than going through a list of hundreds of items to which the code would need to be compared.
Those who like to tweak their ad blocker will be disappointed. Because it was written with size and simplicity in mind, the only option that a user has is whether he wants the extension on or off at a given time. Changing this setting is simple, and can be done through the toolbar button on computers and the Fx entry on Androids.
