New:

Ability to launch element picker into embedded frames, through a new "Block element in frame..." entry in the contextual menu.

Support for match-case filter option, but only for regex-based static network filters.

Ability to auto-complete (<kbd>Ctrl</kbd>-<kbd>Spacebar</kbd>) hostname values for origin-related options in static filter editor according to currently opened tabs.

Click-to-load

Support to replace embedded frames with a click-to-load widget. Examples of usage:

||youtube.com/embed/$3p,frame,redirect=click2load.html
||scribd.com/embeds/$3p,frame,redirect=click2load.html
||player.vimeo.com/video/$3p,frame,redirect=click2load.html

Users of medium mode can experiment with a redirect rule to reveal embedded frames in a page:

*$3p,frame,redirect-rule=click2load.html

Or if you want to have click-to-load only for embedded widgets from specific origins being blocked (reminder: redirect-rule does not create a block filter):

||youtube.com/embed/$3p,frame,redirect-rule=click2load.html
