Convenient when you need it but a huge pain when you don't. This extension makes accessing academic papers etc. easy, but if there if you have your own subscription to said material, this extension will almost always override your account causing HUGE headaches. E.g. I have a personal subscription to The Economist I cannot access without uninstalling this silly extension.

Unfortunately having the extension active used 70% of my CPU, making my fan shriek, my laptop overheat, and eventually chrome would stop responding. Disabled the extension and voila-- fan stopped and chrome went back to normal. Unfortunate because its a good idea for an extension and its a very useful too when it works (especially as a thesis-writing master's student). Too bad it uses all your CPU.

Slows down every request to every website substantially. I *always* see "waiting for extension Library Access" at the bottom when I open a new link.
