... Yes, I know This issue was first reported last July in the official PM forum; according to Moonchild himself:
Broken userstyles.org on Tycho was another reason that expedited the release of (stable) PM28 on the UXP platform...
Thank you both for your suggestions ; this improves considerably over what I have been doing thus far and may possibly also cure the userstyles' (auto-)updating issue...
E.g. for https://userstyles.org/styles/31267/global-dark-style-changes-everything-to-dark
the direct URI to the userstyle (via either suggestion) is found to be :
https://userstyles.org/styles/31267/global-dark-style-changes-everything-to-dark.css
Then I can install it in Stylem 2.2.4 via the "Install from URLs..." feature (so no need to copy the entire CSS code and "Write New Style" ).
However, the main flaw of this procedure, as already pointed out by the both of you, is:
meaning the need for a (second) browser, able to render correctly the site (which could then be browsed/searched normally for userstyles) isn't alleviated... I'm still hopeful that this specific PM27 bug will be properly addressed in due course...
Thanks, I am well aware; site always visited with uB0 ON, some personal "cosmetic" filters also added (to negate their endless plug for the android version of their adware/spyware version of WE Stylish):

The thing is, Stylem (a fork of [XUL] Stylish 2.0.7 made by a member of the official PM community) hasn't been updated in a while and has little support for userstyle "portals" other than the original one (userstyles.org, supported in Stylish); even that support is currently lagging, as Stylem can't install correctly configurable styles (e.g. YouTube DeepDark Classic , with the "Customize Settings" button); that issue has been properly reported here, but the developer hasn't yet acknowledged it or come up with a fix
Also, due to the shady practices of SimilarWeb, current owners of userstyles.org, many style authors are switching over to other infrastructures, e.g. OpenUser.CSS (loads fine in NM27, BTW), and a new "format" of userstyle called usercss (which is configurable post-install); Stylem has 0 support for these ; this new "usercss" type of userstyle and the new "OUCSS" repo are fully supported in the userstyle manager called Stylus , but this is a WebExtension, not installable in New Moon 27/28 (and only certain versions of it can be installed - with some manifest.json modifications - in Basilisk52/UXP).
OT: Yes I know, another long-winded post I am afraid, but hopefully with info useful to the MSFN community
