I keep getting this error in Firefox after a certain amount of time. The error is: "A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue." The script in which the error occurs is the following: "chrome://browser/content/browser-gestureSupport.js" at line 50. The only add-on which is installed is this one: https://addons.mozilla.org/nl/firefox/addon/FF_Fullscreen/. I wasn't able to find any related bugs, so I guess the add-on isn't causing the problem. I've tried the suggestions given on this page: https://support.mozilla.org/en-US/kb/warning-unresponsive-script but these didn't fix the problem. I have tried to let the script run longer, but the only thing this did was cause the browser to freeze without showing the error. The browser is running in Windows 10, using a touchscreen. I hope someone can help me out, thanks in advance!
