Firefox add-on web page blocked by AdGuard

This is urgent:

Firefox v29.01 (latest)
Windows 8.1 Update 1, 32 bit
Latest version of Adguard with updated filters.

Adguard blocks the Firefox add-ons web page (Firefox Menu --> Add-ons --> Get Add-ons:


Normally Firefox allows users to add a security exception for web pages with invalid certificates. But somehow Adguard also blocks this :(

Moreover, Adguard breaks the layout of most Mozilla web pages.

After disabling Adguard protection, the add-ons web page loads without issues.

It is automatic and usually rebooting is the quickest way to fix it or by closing Firefox, restarting Adguard and waiting 30 seconds before reopening Firefox. Firefox is 'special' in regards to handling certificates when compared to IE, Chrome, etc.
