I too am having lots of problems with the new Safari 5.1 update. My system is 10.6.8 (Snow Leopard) and I'm having the trouble mentioned above by many accessing streetsmart.com, the gold site, as well as many other sites that use Java applets.
It seems that this problem is affecting a lot of home users and a lot of businesses. Purchasing managers for corporations are not going to like their teams to be down without a solution for days and days over this. It's clearly a bug that needs to be fixed, and such a glaring one that I'm suprised Safari 5.1 was released with it.
I know, 5.1 is supposed to give us new and exciting security protection, but I find it a little too "new" and too "exciting." I wish I could go back to 5.05. Were there an easy way, I would do it in a heartbeat. Does anyone know the link to the Safari 5.05 installation package? (The above link by laurencefromwichita gives a 404 error.)
Regarding security, I'm all for protection of my home, but a high-tech security system that constantly locks me out of my own house is a waste.
Any of the moderators of this thread, or Apple officials have any idea how we can get our browsers fixed?

I tried the same Applets with 10.6.7 and with 10.6.8. With 10.6.8 :
Safari does nothing (not even an error message).
Firefox shows the applet in its display rectangle but not at the right dimension. Changing the Applet tag parameters width and height changes both the display rectangle and the applet size. Thus the Applet is never fully visible.
A lot of people complain on http://support.mozilla.com/en-US/questions/853621

I found a solution to my applet display problem (as a developer). My applet tags were being generated with the option separate_jvm="true". When I removed this option my applets started to display again.

I reply to myself.
I finally found a bug (a missing character) in the code derived from
The code was correctly interpreted by Safari versions older than 5.1 but resulted in no display at all in S5.1.
With FireFox 3.6.19 I still have a display problem but with that version only.

Assuming your particular problem is the same as mine was, it's possible you could save the HTML page to your desktop, open it in TextEdit (you might have to turn off HTML rendering in preferences) and delete the separate_jvm="true" tag. But there are a lot of ifs in that suggestion.

I know that Safari 5.1 was more or less intended for Lion, but why did the Apple software guys not correct known problems for those that do not have Lion?

I've been trying to work this out and think that the solution I found will work for most of you as well. Go to
Applications -> Utilities -> Java Preferences. Under the "General" tab, make sure the "Enable applet plug-in and Web Start applications is checked. Close Java Preferences and restart your browsers.
I don't know why this information is not more easily available.
Hope this helps!

What OS X version are you using, Obasan?
I'm using Snow Leopard 10.6.8 and there are no options in Java Preferences such as you mentioned. How would a Snow Leopard user fix this bug in Safari 5.1?

Edit: one other thing. If you are using the AdBlock extension, some of the recent filter updates caused problems for me on a few sites that were showing up as Java errors in the error console. That wasn't the cause of all the problems I had, but it was the cause of a few.

wait for Safari 5.1.1 -- wont be long

Thanks again for your reply and your input. I checked Java Preferences in the Utilities folder (Snow Leopard 10.6.8), and verified that applets are set to run "within the browser process" as you suggested. No change needed.
However, clearing the cache seems to have fixed it, at least for StreetSmart.com and the gold site!
(I'm sure I cleared the cache before, but this time it seems to have done the trick.)
Thanks again for your help!

I have just found out from the Scifinder site at
that Apple fixed this with a download, dated 20 July 2011;
Here is the link: http://support.apple.com/kb/DL1421
After quitting all browsers and installing the dmg, Safari 5.1 still wouldn't work with it until I re-started my computer - perhaps this just flushed a cache and I could perhaps have had the same result just from flushing caches.
If Apple would only look at these threads and inform us!
But I suppose by now most of you have found this anyway.

As skeeterpod pointed out on
this is for Lion, not Snow Leopard.

I have the same problem with new Safary on Mountain Lion. It actually works for the originally posted website but it does not for many other.
It is super anoying!
