Maybe it's the upgrade I installed a few days ago, but now Firefox is allowing random adds to play in the background on my Android phone, and I can't stop them. The particular add that's been flaying is a commercial for Verison Wireless.

I recall having the same problem on the desktop version of Firefox for Windows, and I had to go through some procedure I found online to get that to stop. Can't find any information related to Android. Anyway, I've uninstalled it from my Android until someone tells me how to stop these things or until there is a fix to stop them. How is that even allowed? Why would Firefox even allow adds to play which can't be seen or turned off, especially on a phone where data is often limited. It's bad enough it just start playing out of nowhere.
