Symptom

When viewing a PDF in a web browser, the user doesn't see the Save To Worldox button:

The Worldox toolbar is available in the Acrobat viewer (it appears under the toolbars), and can be manually displayed using the menus or by typing the F8 key.

Note: If typing the F8 key does not display the Worldox toolbar, your issue is different than what is covered by this article.  See other articles related to Acrobat or Adobe Reader integration issues in the Troubleshooting Tips and Tricks chapter

Background

This is a known Acrobat bug, introduced in version 10.1.  Details are here:

Workaround

Type the F8 key to get the Worldox toolbar to appear.

A more permanent solution is to go to Edit->Preferences, Internet, then UNcheck the 'Display in Read Mode by default' checkbox.  With this unchecked, Reader will display it's toolbars by default so you don't have to press F8.

You may also need to disable "Protected Mode'.  To do so, in Adobe select Edit -> Preferences -> Security (Enhanced) and unselect the "Enable Protected Mode at startup".

When this is selected you will see the "Extended" menu to the right hand side of your window.  Select this, Worldox and the "Worldox Save" button will appear:

Resolution

At some point, Adobe will release a new build of Acrobat that fixes this behavior
