Mozilla/5.0 (Windows NT 5.1; rv:23.0) Gecko/20100101 Firefox/23.0

Also reproducible on Windows XP x32 with FF 23 beta 7 when loading http://wickedgoodgames.com/java9/rocks.html.

[Paul Silaghi, QA [:pauly]]

FF 23b4 - good.
FF 23b5 - broken.

nightly 25.0a1 (2013-07-03) - broken
nightly 25.0a1 (2013-07-04) - fixed by bug 888834

This looks pretty important since a lot of java games won't load in FF 23.
Anthony, any thoughts?

Comment 5

[Benjamin Smedberg]

That just means bug 888834 needs uplift, correct? It looks like bug 738396 landed on 23, but bug 888834 didn't.

[John Schoenick [:johns]]

I neglected to track this properly :( see bug 888834 comment 19

Comment 7

[John Schoenick [:johns]]

For the issue in bug 888834 this is just a dupe -- the original issue opened in 2010 looks to have been fixed long before that per comment 4. Please re-open if there is an issue here on a branch with bug 888834 landed.

This issue seems fixed with Java 7u25, but with Java 7 update 40 b33 and Java 8 b99  is not working on Mac OS X 10.9. Should I fill another bug since it's reproducible only with beta versions of Java or reopen this one?

If this applet works in other browsers with said java versions then please open a new bug

After further investigations: on Chrome and Opera, the plug-in is not supported. On Safari is the same issue as with Firefox. No need to open a new bug.
