There are a couple of typos in the help.html for Database Browser.
The first line doesn't make sense:
Database Browser Portable is the Database Browser whatever it is packaged with a PortableApps.com launcher
And on the second line database has been misspelled as datbase.
Also, the "Go to the Database Browser Portable Homepage" link is pointing to
https://portableapps.com/tools/DatabaseBrowser_Portable
which gives a 404 error when it should be pointing to
https://portableapps.com/apps/development/database_browser_portable
