About
The Opera Stumbler toolbar, developed by Kyle Anderson, allows Opera users to interact with StumbleUpon to channel surf the Internet and find websites, videos, photos, and more based on their interests.
"Before I switched to Opera, I used StumbleUpon all the time. When I finally made the switch though, I found out there was no toolbar available for Opera users. I stopped using StumbleUpon and started using Digg.
It wasn't until a friend of mine mentioned that she had not 'stumbled' a whole lot since switching to Opera either, and that she was going to use Firefox so she could stumble.
I started searching on Google for a StumbleUpon toolbar for Opera and found this. I installed it but realized that you couldn't actually stumble pages, only stumbler's pages.
Without the ability to stumble pages with the push of a button, this toolbar—and StumbleUpon for that matter—is useless.
And that's what led me to develop Opera Stumbler, a StumbleUpon toolbar for Opera users."
