Now that Waterfox Classic has its own Github repository, users will be able to track and report issues related specifically to it. But more importantly, this will improve the development process of the browser, because previously, issues related to both versions were tackled together. Firstly, users who relied on it will get new versions. This is a welcome move for multiple reasons. The developer cites that it has been difficult to keep the browser up to date with the main project, which is why the two variants have been diverged. Kontos has confirmed that Waterfox Classic will continue to be supported, but it will exist as a separate open-source project from Waterfox G4. Waterfox Classic development will continue No wonder users started worrying, but if you were among them, you can rest assured that it is still being worked on. He had mentioned that its future depended on the ease of porting security fixes from Firefox ESR. You can directly download DownThemAll 3.0.Alex Kontos, the developer of the popular Firefox fork, had previously hinted that the Waterfox Classic version was not a priority. You can directly download Scrapbook 1.5.14 here: Three alternatives that we have tested and work well are Waterfox Classic ( recommended, 64 bit only), Basilisk and Pale Moon. There are several other browsers that support the XUL add-on interface and will be supported after that date. As the new add-on interface "WebExtensions" offers much less options to the developer than the old XUL add-on interface, there won’t be full replacements of these add-ons available. They are not compatible with Firefox Quantum, therefore you cannot use Firefox for download of multiple files or to create a browsable copy of the conference schedule. 'DownThemAll!' and 'ScrapBook' are some of the many add-ons affected.

From the release of 'Mozilla Firefox Quantum' (Firefox Version 57) on, this browser does not support any XUL-based add-ons anymore (now called 'legacy add-ons').
