or reset firefox

• Refresh Firefox - reset add-ons and settings

Hi Waka and thanks for your reply.

I've already tried both options before posting the issue: didn't work.

Do you have the plugin enabled, or activated? maybe its even caused by an outdated version. Have you checked your plugins?

• Please check if all your plugins are up-to-date. To do this, go to the Mozilla Plugin Check site.

or tried in a new profile?

• Profile Manager - Create, remove or switch Firefox profiles

Just tried. Same issue.

If this helps: I'm trying to run an Oracle Forms on Firefox.

Forms Services call java plugin.

My java plugins are up to date:

   Java Deployment Toolkit 7.0.250.17 / status: 	10.25.2.17
   Java(TM) Platform SE 7 U25 / status:  10.25.2.17

Thanks.

Just tried a new profile? Have you tried a new profile?

Yes I did

Your System Details List shows the Java plugin.

Does Java work on the Java test pages?

Try to clear the Java cache.

Hi,

Just tried java Test Pages. The result is: Your Java is working

I also tried clearing the java cached as indicated.

Same issue only with Firefox when I run Oracle Forms applications: A plugin is needed to display this content.

It is possible that there is a JavaScript running on that page that isn't working properly.

You can try basic steps like these:

Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)

Clear the cache and the cookies from websites that cause problems.

"Clear the Cache":

• Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"

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).

• Do NOT click the Reset button on the Safe Mode start window.
