With so many add-ons, themes, people and others that we usually install on our good Firefox browser on a daily basis, it obviously tends to slow down too much; to the point of becoming a martyrdom for many. In these cases, one of the many solutions that exist is to use third-party applications that integrate into the browser without necessarily being a plugin: one of them is very distinguished. SpeedyFox.
SpeedyFox For those who know it for the first time, we will say that it is a free application (not addon) with well-earned prestige since its inception. It is designed to speed up Firefox startup and browsing, and the most relevant thing is that using it is very simple, just one click away. Of course, it should be noted that it is available for both Windows systems, as well as Mac OS X.
SpeedyFox 1.6 It is only 464 KB (on Windows) and 800 KB (on Mac OS X) in size, portable and freeware. By the way, if you are an advanced user, you can use it through command lines that are available in the help menu.
