I noticed something for the past many beta's they do not update automatically and neither does the Stable version update the program automatically despite the option of auto update being ticked. Has the update procedure been modified?
It seems to work just the same way that Proxomitron's "Link Deobfuscator" filter works. It places an semi-transparent, unobtrusive icon over redirected links and shows the "real" url. It's bloody brilliant, and works with AdGuard.
