Screen keeps Loading forever - javascript

So I just started Working with Sencha Touch 2 and I am already running into some issues. I am currently working through the getting started tutorial but then I'm stuck because after I've made some changes and refresh the page, the loading screen just keeps loading non-stop. This prevents me from moving forward with the tutorial because not matter what I do, it just keeps loading. I tried creating a new project but then run into the same issue again. Can anyone help with this? I would really appreciate it.
Thanks!

I think this is because you must have something in your code that throws an error and therefore prevent the application from executing properly.
Maybe you should try to debug it with Firebug
Hope this helps

Firefox page load event very long

I'm going to try to explain an issue that scratch my head...
When I open this website for the first time after opening Firefox (v43.0.3), the UI freeze during about 20 seconds and I don't undersand why. For example you can see that the background image appear after almost 20 seconds...
So, I used firebug net panel to try to understand where the problem comes from and I notice that the page load event is very long but I can't see any tasks executing during this event.
here is a screenshot of firebug Net Panel
When I open the website with Chrome it works fine, does someone has ever encounter that kind of problem ?
I hope that makes sense, thank you in advance.
You're making 31 requests (according to my NET panel - FireBug) which add to 323ms (at least in my case). Your background image is loading ~1s after. Maybe if you'd try to reorganize all that sprites you're requesting into less files - but it seems fair as loading time for me.
I once had a problem with Firebug itself. I had to turn it off and\or uninstall to get the page load normally on Firefox.
In my case it was an effect of problem between Firebug and Telerik Kendo JS Library.
Maybe you have a problem similar issue.
Thanks for your answers, indeed it seem's to comes from my firefox configuration or addons/plugins.
I use a Firefox pre-configured by my socity, so I installed a portable firefox to try if it works and the website is loading normaly.
Now I just have to find from whitch config or addons/plugins the problem comes from, thanks again !

FireFox has stopped showing JS

Last night, I was trying to debug a particular bit of vanilla JavaScript on a private page.
After a half an hour or so, the browser crashed while in the middle of stepping through a troublesome section.
When FireFox restarted, FireBug insisted that there was no JavaScript on the page - does anyone have any ideas what is causing this? Clearly the JS was (nearly) valid before the crash, and wasn't changed before I restarted. The only thing I can see, is that FireBug probably installed an update at that point?
I've tried cutting out all of my code, but nothing seems to make a difference. Other pages, even on the same intranet site, still work, but this one doesn't list any files under the "Script" drop down.
I've compared with the built-in Dev tools, and they also show no JavaScript loaded. The JS is a form submission handler, and clearly it is no longer running when the form is submitted.
I struggled with this for much of today. Eventually resolved it by creating a new profile.
I would be very interested in learning of the root cause if anyone figures it out.

How to solve Unresponsive script error programatically

I am using kendo in my application and at sometime one of my pages is showing this error in IE and Firefox.But its working fine in Chrome.
A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: resource://firebug/firebug-service.js:3442
I have searched and found that setting the value dom.max_script_run_time of this will solve the problem.My question is that is it possible to set the value programatically.I mean by using javascript or jquery.If so how.? Any help is much appreciated.

Firefox Javascript stop error

When I run Firefox and open any website, after some time I am getting JavaScript Stop and continue error, and the page is getting hang up. Can anyone please help in resolve this?
If you really have the problem on every page then much probably the issue is caused by your broken Firefox profile or some badly written addon/plugin you've installed. Reset your profile or disable/uninstall addons and plugins to see if it helps first.

Firefox and IE continue to load after content has been inserted into a DIV

I have a situation where I'm inserting javascript generated HTML code into a DIV. One would think this would be a no brainer, but for some reason, once the code is in, the status bar and tab loading graphics start up in both browsers and never stop again. The page continually appears to be loading data, but in reality, there's nothing more to load. Any idea why this may be happening? Solutions? I appreciate any help. Thanks!
Install the Firebug plug-in for Firefox. Open it up and got to the NET tab. That will allow you to see your network activity. Something on the server may be stalling. This will help you find it.
