I have been encountering a warning in Bon Echo lately which told the that a script on the current website was unresponsive asking me if I wanted to stop or continue. Thatâ€™s a pretty vague warning and I was puzzled at first about the cause of it. The strange thing was that the website seemed to have loaded completely and that the warning was displayed despite of this.
If you suspect that a script just needs a few more seconds to run you need to edit a setting in the Bon Echo config. Type about:config in the address bar and filter for the string dom.max_script_run_time. The default setting is 20 (seconds), just add a few more, raise it to 25 for instance.
