I noticed recently that I have 60 extensions installed and active in my Firefox, but I noticed also that lots of them I don’t use anymore or I have installed for testing. So I started to clean up my extension list and kept only addons that I frequently use, the final list stopped at 37 active extensions, and 23 have been removed. But most important thing I have to notice here that memory usage have been considerably slow down, so it’s interesting to clean up your extension list and remove things that you never used or used only once.
