Firefox, everything has changed from March 14th: what happens to the browser


Tomorrow, Friday 14 March 2025, will be very delicate for those who use Mozilla Firefox To surf the net, since not updating the browser to the latest available version we risk losing a series of important features.

At the moment the latest version available is 136.0.1, so you don’t risk anything in the event that the upgrade has already been made, or if this has been automatically launched by the program. The problem arises for those who remained anchored to an obsolete version of the browser, and it is precisely for these users that the deadline of the March 14th It is particularly important. If Firefox does not be updated by tomorrow, you risk not only losing the extensions installed, which will be disabled, but also to see the content protected by DRM stop, or streaming services such as Netflix.

But who risks seeing these features cut? In principle, those who use Windows 10 or Windows 11 for example should be able to sleep peacefully: in most cases Firefox provides for automatic updating to its first useful start after the distribution of the upgrade, and if not so it is possible to manually provide for a verification and a more recent search for a search. On the other hand, the situation is different in the event that obsolete operating systems are used: the root certificate concerned will expire for users who have not yet updated to version 128, already available from July 2024, for users with Firefox ESR preceding version 115.13 and for computers managed by operating systems that are no longer supported such as Windows 7/8/8.1 and macOS 10.12/10.13/10.14.

As specified by Mozilla, the browser can continue to use even with a root certificate After expired, however, apart from the loss of extensions and the risk of seeing streaming services stop in the event of updates by the latter, the safety of navigation on the net would be strongly compromised. Thanks to the Extended Release Support, Firefox grants the possibility to those who use obsolete operating systems to obtain a still valid root certificate: the support for ESR 115 has been recently extended for an additional 6 months.

To avoid misunderstandings, to understand if our browser is already ready for tomorrow’s passage, simply check the installed version by opening a web page and then selecting menu-help-information on Firefox.
