When firefox says: a web page is slowing down your browser what do you want to do? >wait >stop it, does it let the page continue by default?

more options

I created a javascript script that generates the mandlebrot set using P5.JS . It's worked fine for smaller versions, but now I want to try creating a large version to save as my desktop image, however Firefox keeps telling me: "a web page is slowing down your browser what do you want to do?" then giving me the choice between "wait" and "stop it". If I click wait, it will shortly ask me again. This is annoying for two reasons: I don't know if the script will continue if I don't click wait, and I want to just leave my computer for a few hours while it works stuff out, which I can't do if I constantly have to click wait and I don't need telling the browser is being slowed down, I know that will happen as a result of my script.

Is there anything I can do to get rid of this message for my specific page? Will Firefox continue to run my script if I don't click wait.

”Webpage is slowing down your browser” This is the new way the browser tells you there is a problem with the script program(s). https://support.mozilla.org/en-US/kb/warning-unresponsive-script?cache=no

I know their isn't a problem with the script because I wrote it and have used it to create lower res images. TBH it doesn't sound like you read my question in much depth.

The problem is with the script and high-res images - not with Firefox!

https://support.mozilla.org/en-US/kb/warning-unresponsive-script That page tells you how to increase the "time" that Firefox will wait before displaying that warning message via adding a new pref of dom.max_script_run_time .

How can I fix the problem: "A web page is slowing down your browser?"
