The Waterfox Project has completely dropped support for the Waterfox Classic Browser Portable as of April 2021 when the last Portable v2021.04 was published on its release site..... https://cdn.waterfox.net/releases/win64/portable/
From that point on the only way to update the Portable version was through the Browsers internal update feature, which halted with v2021.08.1
MrAlex94, the Developer, created a new & final download & information landing page for Waterfox Classic ....... https://classic.waterfox.net/
The latest Full version available is Version 2021.10-classic Released on 2021-11-10
Being the Portable version will no longer be produced, supported, or updated, the only Waterfox Classic version available is the Windows Full Install Version, that can be downloaded from https://classic.waterfox.net/
Therefore, I am respectfully requesting that PortableApps.com take up production of this Browser in a portable form.
Thank you for your time & consideration regarding this request, & I am quite sure that the many thousands of homeless past Waterfox Classic Portable users will deeply appreciate it if you see fit to take up this project!
Again, Sincerely,
BobbyW.
