SourceCheck от Dylan Mitchell

SourceCheck is a Firefox Browser extension that checks the current domain of the current page, as well as the domains of all of the links on that page against a list of unreliable domains.

The list of unreliable domains comes from https://github.com/OpenSourcesGroup/opensources. I'm actively looking for a better source for this list, as it appears that opensources.co is a dead project. The unreliable domains that are found will be highlighted, and denoted with a caution emoji. To see the reason why they are highlighted, click on the SourceCheck Icon.
