User reviews

It's a simple, easy-to-use yet very customizable extension! I wish I could change the icons for my custom sources, whether to choose one from Material Icons, to fetch the favicon from the website, or just to let me specify the URL myself.

I've been using Definer for months and so far, it's the most satisfying Chrome extension I've tried. I just wanted to thank you for creating this tool. As someone who easily loses focus, this extension has been a tremendous help in keeping me engaged while reading and looking up information I'm unfamiliar with.

This is SOOOO helpful, I love it the way it is. But would you be able to adjust the text size on the bubble as well? Not just the bubble.
