Firefox does not save my Home Page preference

Hello
This is a known bug affecting Yakkety and fixed in Zesty, workaround is here:

Ubuntu MATE always forces search start page in Firefox

I am huge fan of both Ubuntu Mate and Firefox, but rather frustrated with U-Mate changing my e-mail ‘home-page’ to a ubuntu search page. What do I have to GIVE UP? MATE or FIREFOX???
