I don't know the reason, but my ad block kicked in; uBlock Origin has prevented the following page from loading: http://ww.gamehouse.com/

Can connect to ww.gamehouse.com and download game. When try to open game get a continuous "connecting to localhost". Game does not open. Have contacted gamehouse but messages they send are blank.

The correct URL is  : http://www.gamehouse.com/#/

have always had an ad blocker and always worked. Typo should have read www.gamehouse.com. Does connect to site but does not load game.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}

starting in safe mode did not solve problem. game downloads but does not open.

Did you check out Firefox's Tracking Protection?

Is the game a separate program, or something played in a browser window?

Site does not have shield icon indicating tracking. Game is downloaded off site. When Run clicked only get connecting to localhost.
