It looks like Apple updated the code to detect which client you are when connecting to the app store. I checked and they have script that called a function its.detect.Itunes which detects what browser and operating system you are on, and if it isnt Safari, the link does not return an app store link.

Interestingly it does seem to have handlers for chrome and firefox, but either they made a mistake or they are purposefully making it so you cannot use Firefox to one click browse the mac app store.

I checked if switching firefox's user agent worked, and while it did load the page momentarily, and the function clearly had a anchor link instead of a direct href, it immediately redirects to a blankly loading page forever.

At this point it looks like it is probably safari or bust.

NoScript

...can block plugins which you enable once via click-to-play or permanently by white-listing domains that they load content from.

While its primary aim is preventing malicious JavaScript from running, NoScript effectively blocks Java™, Silverlight™, Flash®, and other plugins and embeddings (such HTML video/audio elements and downloadable fonts) on sites you didn't explicitly whitelisted.

Java Applets, Flash movies/applications, Quicktime clips, PDF documents and other content won't be even downloaded from sites where you consider them annoyances or dangers, saving your bandwidth and increasing your navigation speed.

NoScript's settings for blocking plug-ins can be found in:
NoScript Preferences → Embedded Content

Overall though, I'd not recommend this add-on if your goal it to merely to reduce noise. NoScript has been written first to block javascript and it is a wonderful tool for that. However, because it's so powerful and configurable, it can be difficult to use for newcomers and takes a while to setup.
