Can't find webview.db file for android browser to view saved passwords in internet app
[LG G2 4.4.2 rooted]

I couldn't find webview.db either but opening the file ACEBrowser.db which was in the data/data/com.android.browser/databases had all the required information under 'password'.

Took me hours to realise this. Hope this helps someone else to do so quicker :)
