App request - replacing Mozilla's programs

With all Mozilla dicks moves over the years, it becomes clear that there is no more Foundation, who stayed for free Internet, like used to be, and current Mozilla becomes just a curtain to cover shady business.

So I propose to remove all Mozilla's app from the project and replace them with alternatives.

For web browser:

Waterfox as obvious Firefox replacement (the same engine, support for add-ons)
Official website: https://www.waterfox.net
Github: https://github.com/BrowserWorks/Waterfox

Not so obvious (because based on chromium):
Vivaldi web browser (privacy focused, no monkey businesses, creating by old Opera team members). Open source... in most part.
Official website: https://vivaldi.com/

For e-mail client:

Mailspring? Community edition comes with GPL v3 license, however have also some "Pro" edition with extra stuff. Community one does look decent and not very limiting in base use case.
Official website: https://www.getmailspring.com
Github: https://github.com/Foundry376/Mailspring

Claws Mail - slightly dated and basic, but open source and still developed, or rather maintained.

Betterbirs - it's like Thunderbird, but better Like Waterfox above, so-called "obvious replacement". They fixed some bugs in Thunderbird reported ages ago and added some new things. Also, despite a relatively small team, they are still more trustworthy than Mozilla.
