Works great on Firefox Windows 10, however on my laptop running Windows 11 it crashes every time I try changing a setting. It also doesn't appear to be passing my link anywhere as when I click the icon it just refreshes rather than loading it through a library site like normal. I've tried uninstalling, rebooting, and reinstalling without luck. Appears to just be a bug related to Win 11. Hopeful for a fix down the line because it's a super useful utility.
