You need to manually uninstall the extended kernel, a restore point will not work. As I said, you need a portable copy of Firefox.
I wish I knew that earlier. It's too late now. It's no big deal having to do another clean install. I want to try a couple of new things anyway.
A new clean install of Windows Vista SP2 64-bit has been done and brought up to date to March 2022. Some minor changes were made to the install and update guide.
Not true. There already is a much newer version of Mypal now named Mypal68, despite saying “yet unstable” (this term is actually referring to usage on Windows XP), it actually works much better on Windows Vista.
After the contents of the .zip file are extracted, double-click the mypal.exe file to load a web page, then go into its settings section. Most of its settings are a copycat of Mozilla Firefox.
For videos to load well and stop stuttering in Vista Ultimate sp2 32-bit, which browser works well? IE9 did not load the site at all, Firefox (forgot to check the version, but I assume latest for Vista) did load, but not very well (unresponsive for a time, then the video roughly works; other parts of the site remain empty). Oops, just noticed I am replying on a forum post that no one replied to since June 2022. Hopefully I didn’t break any rules doing this?
Mozilla Firefox 52.9.0 ESR is the browser I use in Windows Vista Business SP2 64-bit. I haven't loaded any web page videos with it, so I don't know how well they display and work with it.
