This works fine for me. Are you using the latest Java version?

Yes ! JDK 6 update 11. And i'd try with an older version with the same results...
If it works with yours and not with mine, i don't understand...

Maybe caused by an add-on, or a profile corruption.. You could try safe mode or a new profile to find out:

I've try with multiple PC, but problem still present...
I've seen some PC who worked and another not.

It's strange for me. In my home, i've 3 PC, 2 doesn't work and 1 do.
On my workplace 3 work and 4 doesn't work... I don't understand anymore...

So, Thank a lot for your help.

Have you uninstalled all previous versions of Java before installing the latest? That _might_ be the cause. WFM as well using: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4

No. There is only one Java Runtime Environment at time on my computer. ^^

When i' ve test older version, i've uninstall current version and clean registery, environment variables... Before install another version of JRE (JDK).

I think it's not the cause of problems.

Closing since now after whiteboard closeme date and no reply to last comment.

Please reopen/comment with further info, if you still see this issue with Firefox 3.6.13 or later in a clean profile.

If you wish, you can also try to reproduce in Firefox 4 Beta 8 or later, since it is possible the issue has already been fixed in Firefox 4:
