Cannot download incompatible addons for 4b2, even though checkCompatibility is False

more options

I downloaded 4b2 on to a new Windows 7 machine. I want to download some "older" addons that aren't yet compatible with 4b2. So I downloaded the Compatibility checker addon, plus manually ensured 'extensions.checkCompatibility.4.0b=false' was set in about:config.

When I go to the Firefox Add-On site, I get an error that there was a "connection error" with addons.firefox.com ONLY when I try to download a non-compatible addon (AdBlock worked, for instance, but it's compatible).

This happened

Every time Firefox opened

Yup,

Beta2 broke a ton of stuff

Most of the extension developers should be aware, but if there isn't a comment about updating to beta2 on the addons page, it couldn't hurt to add it.
