Firefox theme integration doesn't check for internet connectivity at first and then displays unexpected outputs.
Steps to Reproduce:
1. Open Tools -> Options -> Libreoffice -> Personlisation
2. Click Select Theme buttom.
3. Search for a valid theme without internet connectivity.
No theme found.
No internet Connectivity.
User Profile Reset: No

I believe the plan going forward is to drop the connectivity feature and just ship a curated collection of themes.
I guess we can close this as a dupe of bug 123228.
Anyway, I buovjaga said, the long term plan is to drop this feature...
