uBlock Origin will soon stop functioning in Chrome as Google transitions to new browser extension rules.
I have that problem too but I find using a Chromium-based browser is the solution. I doubt you actually need to use Chrome for these websites you’re having problems with.
i mostly use a vivaldi or opera portable for those. unzip, run, use the temperamental site, close, delete directory. it’s not very often that i have to do this.
but for a couple of pesky sites i do frequent a bit more often, i keep their portable browsers to reuse and have them configured (including addons) specifically for them.
