Normal Firefox can be installed in two ways:Īdd a new repository to the application sources, import the corresponding keys and install an executable file from this repository. If you are not sure whether you need it, then you do not need it – use Firefox ESR. That is, to install normal Firefox or not – you decide. This article is dedicated to this issue – you can install a regular version of Firefox on Kali Linux without removing the default version Firefox ESR. Nevertheless, some programs require the latest version of the usual Firefox in which there are all modern features. And that's all – there are no other differences. From time to time, the version of Firefox ESR is updated to the current one, and then again “freezes” in its development. If to reduce to the dry rest, then in fact Firefox ESR is a usual Firefox which loses new functions and is less often updated, though it receives security updates. The letters ESR mean Extended Support Release.
