Hi @roytam1, is there any chance you can build a x64 version of NewMoon 26 ?  There is an "official" Pale Moon 26.5.0 x64 build, but most sites cannot make a secure connection and showing this message "This Connection is Untrusted".

no intention making x64 builds for versions before 27.

There appears to be no documentation supplied for Mailnews, so I hope someone can help me with Gmail and Microsoft Outlook.com mail.  They both require OAuth2 authentification, but only Gmail can connect to the server if I use IMAP.  When I use POP3 as the incoming Gmail server I receive this message:

The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: invalid SASL argument cdcc0902adbc2-3b63b1f8890mb165044463d76

OAuth2 does not appear to work with Microsoft Outlook.com mail and it produces the login window uploaded here.  I tried enabling 2 step authentification and generating an app password to be used as a normal password, but I receive an error message saying "Username and password not accepted".  Does this mean that Mailnews needs to be registered with Microsoft for OAuth2 to work?

I changed pref. dom.ipc.processCount from default 1 to 4 (no multi-process enabled for now, browser.tabs.remote.autostart: false).

Is it just my imagination, or do websites load better and Serpent 52.9 uses memory less wastefully and actually recovers it after closing memory-hog sites?

I can't imagine that pref. doing anything at all if multiprocess move is disabled, so I strongly suspect either it is your imagination, or else you do actually have multiprocess mode enabled. The pref. you cited is not the only way to enable it:

Quote

You can force "multiprocess mode" (aka "e10s") in ... @roytam1's Serpent 52 and 55 by creating the Boolean preference browser.tabs.remote.force-enable and setting it to true. This splits ... Serpent into two processes.

To allow more than two, set dom.ipc.processCount to a value greater than one (i.e., setting it to 2 allows 3 processes, etc.)

...

[W]ith ... some other FF forks on XP (confirmed with Serpent 55), you can instead ... toggle browser.tabs.remote.autostart from false to true, and if necessary (due to add-ons flagged as incompatible with e10s), toggle extensions.e10sBlocksEnabling from true to false.

You can check whether multiprocess mode is, in fact, enabled by clicking Help / Troubleshooting and scrolling down to "Multiprocess Windows." If the first number is anything but zero, it's enabled.

Then make it so that extensions made for palemoon can be installed without questions in all your browsers, with any min/max version. Extensions from realityripple.com, addons.palemoon.org. Or make an extension that disables checking.

Already done: https://github.com/JustOff/moon-tester-tool (by the author of the Classic Add-Ons Archive himself) and https://github.com/Nebula-Mechanica/serpent-tester-tool. But to be fair, these extensions are themselves several years old, so they probably need to be updated. ... Any volunteers? @AstroSkipper?

On the topic of New Moon 26, would it be possible to provide instructions on how to build K-Meleon 74?

Where do the SSL certificates in New Moon come from? I have never had to add missing certificates in this browser unlike other old browsers.

it uses same cert store as latest firefox's security library (NSS) so it has latest certs.
