Not only does this product allow a user to incorporate references into bibliographies in an easy way, but incorporates modern ways, including a lot of customisations to be done. Also, if you include a URL, you have the option to automatically have that URL saved with archive.org, and your reference will be permanent.
Pros:Some thought has gone into this Chrome extension, allowing the user to simply add material into its bibliography, including modernities.
Cons:I've not found any, yet.
