Bug 125209

Description:
In the menu Tools - Options - LibreOffice - Personalization, when choosing "Own Theme" and "Select Theme", the dialog "Select Firefox Theme" was appeared.  However in this dialog no matter I chose any category or directly paste a specified Firefox theme URL and click "Find", always no result was found.

Steps to Reproduce:
1. Open LibreOffice (any component)
2. Choose "Tools" - "Options", in the LibreOffice section choose "Personalization"
3. Choose "Own Theme" and click "Select Theme"
4. Change the item in the Category dropdown menu.  No results are found with any Category.
5. Paste the URL of a specified Firefox theme (for example, https://addons.mozilla.org/en/firefox/addon/tattoo-passion_27/) in the upper box and click "Find", no results found either.

Actual Results:
Can not find any theme from Firefox.

Expected Results:
It should allow me to choose from a specified category or allow me to download it directly.


Reproducible: Always


User Profile Reset: No
