very helpful as are the people who answer questions for this addin

Very useful for looking up books on Amazon or Goodreads. I had to get 2 URLs fixed for libraries in Brisbane region but then they worked fine.

Very cleanly integrates into websites like Amazon and Goodreads with minimal intrusion and almost no setup necessary. Useful as a reader and someone who hates obnoxious clutter from extensions.

This add-on makes finding books you wish to read but not purchase a breeze. Love it

This is a terrific idea, really well executed. Initially I found it didn't work for my local library, and (to my amazement) when I contacted Library Extension support, it was fixed within a day.

This is such a wonderful convenience. I use it constantly.

Smashing add-on for readers and students. The tedium of going to the library website and investigating availability is over. I use this both from organic and context-menu search results to view two libraries' results at once to see how I can get the book or download fastest. If you can read this, you need this extension.

It's so convenient to see my libraries' holdings when visiting Amazon or Goodreads! I listed two libraries as well as Hoopla. The plug-in's response is very fast.

I had a technical support question and was answered within the hour! I'm very appreciative.

This is by far the most useful extension I've ever downloaded.

WOW!! I have 10 different (all legal) library cards. When I wanted a book I used to have to log into each library (Overdrive app) and search for the book I want. This is amazing. It saves me so so sooo much time. And I know exactly which library to log into to get the book I want. I just wish I had known about this extension sooner!! 10 stars!

Great extension. Superb support. Why isn't this and many other fine extensions usable by Firefox android. This extension is the ONLY reason I use(d) Firefox on my Androids. Kiwi is faster and Puffin works with problemation CMS's better than FF.

My favorite extension! It makes quick work of my library's multiple databases and sources. After 3 years of using it I'd like to repeat that it's such a great idea and a great time saver. The shortest path to a desired book is Library Extension!

Thank you for one of the only working tools to connect to my not-always-well-connected local library (not in WorldCat etc.).

I love, love, LOVE this extension. It is so convenient to be able to search for new books in one spot (I use goodreads, but it works on amazon too! amazing!!) and be able to check the catalogs of all three library systems I am a member in.

Thank you so much for this fantastic extension!
