I believe Spiral Knights is a java game. Have you downloaded the latest java runtime environment? Also need to make sure your browser allows a third party app to run (or install).
To add, you'll need to allow JavaScript (note: not the same as Java) for spiralknights.com for the game to load.
You'll then need to allow JavaScript for threerings.net for the Java app to be called upon.
In Firefox that i'm on, this then calls on the Java Plugin 7 update 45 (SE7 U45), which for some months now at least (I believe. I think it had been marked safe again inbetween for a short bit) has been tagged as unsafe by Firefox, and so disabled by default.
Ergo, I am not allowing it. Use at your own risk, I'd say
this then calls on the Java Plugin 7 update 45 (SE7 U45), which for some months now at least ... has been tagged as unsafe by Firefox, and so disabled by default.
For the sake of completeness, the same goes for the Java Deployment Toolkit 7.0.450.18 and then some, being tagged as unsafe and so disabled by default in Firefox.
I wasn't looking as closely before, and anyway I assume it's the plug-in that's at stake here, not the deployment thingie whatever.
pps So looking into the backgrounds of it some more, I find it hard to say so have the Firefox folks found these plug-ins unsafe in combination with Firefox, or these versions or what are they of Java unsafe, per se?
Beats me. I know e.g. Internet Explorer I've never noticed being coy about its implementation, but maybe they have other ways of controlling or blocking it; or they're irresponsibly sloppy about it, or maybe Firefox have their heads up their you-know-where's.
