@syntax You can. There are two was to do it, the easy way, and the proper way. The easy way is enable MIME requests in chrome://flags then go to crxtractor and type in the URL of the plugin you want, it will then give you the option to install it. The proper way involves getting the google crx install link and appending your version number and plugin ID. If you want to follow this route let me know and I'll reply with the necessary URL.
@ThreeBadgersInATrenchcoat It seems I was able to simply download the source from respective repos, unzip, enable developer mode in chromium then just drag the extracted folder into the extensions area. Both uBlock Origin and NoScript seem to be running fine now.
