This happens with just about any game on AG for me, currently. Ads before the game still play, but the game itself isn't launched. [IMG]http://i.imgur.com/7jrnEvA.png[/IMG]
I reckon you may need to look at your plugins and see if that's all runing well. At my end (Firefox 21), that's under >Tools >Add-ons, now in the resulting window check both your extensions and plugins.
Also, check if you don't have an ad blocker or similar running that stops Flash Player from working, both for this site, and in the case of MMO (multiplayer) games the sites that they may actually be hosted on.
Well i checked my add-ons too and all of them seems working pretty well, i can open games from other game sites,i can watch videos and gifs etc. just armor games is not working there is something really wrong over here (btw fyi, i can open Dawn Of the Dragons without any problems and i tried to open other games like "The Last Stand(this one got stucked at connecting armor games)" and "Swords and Potions" working well like Dawn Of the Dragons).
Woops. I didn't think that would actually work. Anyhow, as you can see, I have everything unblocked using NoScript and it still isn't working. It's still showing me the white screen and the game doesn't low no matter what.
This happens to me on every regular game (not on MMOs) no armorgames.
Beats me, Karasaar. I reckon you're blocking something somewhere in your Firefox settings -- but where, indeed. You could fiddle around some more with do you allow the right cookies, the right pop-up windows, and such. Go over all your settings and see if it could be related. (And let us know if you find out anything )
(Also, if you right-click in that white frame, it might give you some applicable sub-menu to make some adjustments in? But it very well might not.)
But seeing how you say Opera works fine for you, I guess instead of breaking your head over it, I might settle for that.
ps Silly comment maybe, but have you gone over your Flashplayer settings, to see if you're not accidentally blocking some necessary content there?
In WinXP, that would be under >Control Panel >Flash Player, now check under local storage settings or whatever it's called in English. You shouldn't be blocking the necessary sites there from storing data on your machine.
