Really useful for research and awesome for open web. Misses a bunch of articles, for example on Research Gate, should be a way to for community to add articles / sites to improve it.

Fixing a problem that should not have ever been one.

This is part of the world I was promised as a child. There should be no paywalls to research that is even fractionally subsidized by the common wealth.

Well, be honest... We all think that research, most likely paid for by research(ers) institutions, should be available to research(ers) institutions. And yes, I too signed over my copyright in the past, and was forced to pay for my own publications. Decades ago nobody gave it a second thought. Nowadays that changes luckily. Albeit slowly. So with that in mind, I love the idea behind this addon. But I removed it again. It doesn't function without javascript, which is a PITA. Even before reviewing the fact discussed here that it changes page code... So, as somebody else here already mentioned, perhaps better to search whereisscihubnow...
