Like the concept and the effort. But need to have some pre-prescribed settings to make things easy for non-techies. Disabling for say 5 min as an option to switching on and off. Also, some indicator showing that it is this extension that may be breaking or blocking the site. Thanks.

some website like keycombiner has a timer while practicing. so, i use this extension to block the settimeout api, but then the website just stops loading the page. it would have been worked if it had an option to stop an web api while working instead of blocking from the start, then the page would start normally and would worked correctly.
