In addition, ESR can use certificates installed in the operating system without problems, without having to install them in the browser's certificate manager. Firefox ESR does not require these to be signed, which greatly facilitates the development and installation of private extensions within organizations. So until the launch of the next ESR, which will be accompanied by Firefox 88, and which will bring all the changes released from version 79 to version 88.Īnother difference between this version and the normal version is when installing extensions. And the same will happen with Firefox 80 and ESR 78.2. For example, Firefox 79 will bring a series of news and changes that will not be implemented in Firefox ESR 78.1. The differences start with the following versions. Of course, the ESR version usually brings some features that are disabled by default (although we can enable them if we need or want to use them) because they are not considered essential or stable enough as they are. For example, Firefox 78 and Firefox ESR 78 are virtually identical. In a general way, the same normal version and ESR generally provide the same characteristics. In addition, it allows system administrators to plan bets à jour, thus reducing the impact and improving the experience for all employees in the company.

This browser is also intended to be configured remotely so that administrators can activate and deactivate functions and control the overall operation of the browser. It also has an installer that allows you to install the browser from a central computer on all computers on the network (Windows and macOS) instead of having to do it one by one. In it, we can see an improved tracking blocking system, as well as DNS over HTTPS support enabled by default. The ESR version is a version that has greater confidentiality compared to other editions because it is focused on business. Like the normal version of the browser, the ESR receives emergency security fixes, which are reflected in another subversion (eg Firefox 78.0.1, 68.5.2, etc.).Īlthough its main feature is long term support, it is not the only functionality provided by this branch of the browser. In other words, Firefox 68 ESR will receive updates until the release of Firefox 80 (which will be version ESR 68.12) and, from that point on, the browser will no longer be supported, having to upgrade to the latest ESR. Each ESR version continues to be updated for two additional cycles.
