Great When It Works

When this app works its great but there are ongoing issues:
1) some pages get stuck when scrolling up/down, meaning you need to restart the app to get them working again,
2) links in StumbleUpon emails dont open in the app, they open in the browser
3) the app takes up a lot of internal storage without any option to clear out visited sites
