The Firefox Web browser is more than a navigator — it’s a veritable online ecosystem that is continually expanding and evolving. This is largely due to software plug-ins called “extensions” that turbocharge Firefox with additional capabilities. I have access to hundreds of the modules, which typically work on both PCs and Macs, and I use several of them daily. More extensions are continually being developed and released to the public, usually for free. I wrote about Firefox last year, but I’m taking a closer look at extensions.
