I was a little suspicious after looking at the project entity name (Fenrir). But, I decided to take a look at...

Sleipnir 2.7

...anyway. I had just read some good reviews of this alternative freeware Windows browser. So, I installed it. Ran into a problem installing the optional Gecko engine plugin. The browser seems fast though a bit quirky. And, I'm not really sure what it is after looking at its options. It looks like a shell over Internet Explorer (though I could be wrong). I removed it after testing it a bit. Didn't see anything compelling to keep it on my PC.
