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.
Solved! Go to Solution.
Coming on to you problem
I think you have problem with Cross-domain Content Scripts
By default, content scripts don't have any cross-domain privileges. In particular, they can't:
Check this article on mozilla addons for additional info Cross-domain Content Scripts
(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box above the list, type or paste java and pause while the list is filtered
Firefox does not have a user interface for applying site-specific scripting restrictions, but this can be done using extensions or using "capability" preferences. I don't see the best known script blockers on your extension list (NoScript, YesScript, Controle De Scripts) so I suggest checking for the hidden preferences first.
Open your current Firefox settings (AKA Firefox profile) folder using
Help > Troubleshooting Information > "Show Folder" button
Scroll down to prefs.js and open it in a text editor (note: you can't save changes while Firefox is running, but you can exit Firefox if you find something you need to edit out)
To test the extension possibility, could you try some of the problem sites 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)
jscher2000 I could not find anything related to capab in pref.js . And I have already tried to Troubleshoot Firefox issues using Safe Mode. It didn't work out. Thanks for the help anyway.
So, is there any other way possible? I'm ready to try anything.
You can try to set the security.csp.enable pref temporarily to false on the about:config page to see if that helps.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
If content is missing or otherwise not working when a secure https connection is used then check if there is a shield icon to the left of the "Site Identity Button" (globe/padlock) on the location bar indicating that content is blocked.
You can use the Web Console (Firefox/Tools > Web Developer;Ctrl+Shift+K) to check the Net log to see if any content is blocked or fails to load.
cor-el and anushbmx, I checked in safe mode also, still gives the same error message.
NOTE: I checked on 3 of my friends, there Firefox 24 ALSO shows the same warning given by Stack Overflow. How is that possible?
