The new update of this once-nice plugin is now loaded down with the Jollyworks spam/malware/adware plugin, and harms other websites that you're on by overriding their links.
This is now a dangerous plugin and should be removed ASAP.
Removing the plugin removes the malware as well.
The updated Webpage Screenshot claims to be "partnerer" with Jollyworks, but this is unlikely. Either waym, remove it. Honestly, it was never half as good as the comparable plugin available in Firefox.
