The launch of Firefox Quantum, the latest major overhaul of the Mozilla foundation's browser, hit the market last year, with important new features, for both good and bad. On the good side, we see how the speed and security of the browser have increased considerably. On the negative side, we find how extensions began to be called WebExtensions, representing a very important change.
The new extensions called WebExtensions, they are much easier to develop and also offer a greater number of functions. The only extensions that we can install in Firefox Quantum are of the web type, so the add-ons that had accompanied us in recent years had stopped working. Fortunately, the Firefox extensions store offers us more than enough alternatives to find alternatives.
But if you still make use of an old version of Firefox, you could continue to use the old extensions, make use of it at least until October, since according to the company, the Mozilla foundation will remove all of them from October. The latest version compatible with these old add-ons, Firefox 52 ESX, will stop receiving official support on September 5.
It's been a year since Firefox Quantum hit the market, more than enough time for developers have updated their old extensions to web type. If this is not your case, it is probably time to look for alternatives to your old extensions, as long as you are not using Firefox Quantum.
Mozilla wants all users to upgrade to the latest version of Firefox currently available on the market, and that incidentally take advantage of all the news that the non-profit foundation has been introducing in order to become an alternative to the all-powerful Google Chrome, a browser that today has a market share greater than 60%.
