Firefox Bowser 8
Works nicely on the Fire. Has some pretty cool features too like being able to save a webpage as a PDF (Options Bar --> Menu --> More --> Save as PDF). PDFs are saved in the download
folder. You can access the folder with any File Explorer App.
The only thing I found out about Firefox is that you have to properly shut it down before exiting. However, I have noticed this about a few other Android Apps lately so this is good information to know. Especially if you have an App that worked and then starts to give you problems later after returning to the Carousel Home Screen.
Update: This bug appears to be fixed from version 7.
With that said, to properly exit Firefox (Options Bar --> Menu --> More --> Quit).
