Hello, Sometime ago I suddenly realized that JavaScript was not working in my Firefox. I get a very explicit error message from Stack Overflow:

"Stack Overflow requires external JavaScript from another domain, which is blocked or failed to load."

Many other websites also do not work.

I currently am running Windows 7 and on typing "java -version", I get the following output:

java version "1.7.0_40" Java(TM) SE Runtime Environment (build 1.7.0_40-b43) Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)

I know Java is installed and working because I can compile and run .java files from NetBeans.

I am in a fix as I have spent many hours troubleshooting this problem but could not solve it. I am very hopeful for a solution here.


Chosen solution

cor-el I was experimenting and installed Firefox 25 Beta 3 and all JavaScript are working fine.

Hi TheDarkPassenger, could you try StackExchange in Firefox's Safe Mode? That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: Troubleshoot Firefox issues using Safe Mode.

You can restart Firefox in Safe Mode using

Help > Restart with Add-ons Disabled

In the dialog, click "Start in Safe Mode" (not Reset)

Any difference?

If this happens with a secure (https) connection then you can check if there is a shield icon to the left of the "Site Identity Button" (globe/padlock) on the location bar indicating that mixed active content is blocked.

You can also check the network tab in the Web Console (Firefox/Tools > Web Developer;Ctrl+Shift+K) for errors.
