Java causing Vista UAC for Firefox
I’ve been bugged by an issue with Firefox 3.5.3 and Java 6.15. Every time I open FF or try and run a video from news sites I get the UAC popup. Not a big deal but it is annoying none the less. the interesting part is that it was happening at work (Vista Business) but not at home (Vista Home Premium)
After a little research I found this solution
Disable the extension "Java Quick Starter".
I had the same problem running 3.5.2 on Vista Business with java 6u15. I didn't have the problem on my vista home premium laptop running 3.5.2 with java 6u13, so I looked for differences. The first important thing I noticed with this add-on, which apparently gets installed with java versions of 6u10 and later (my other computer initially had an earlier version installed, so it never had the extension installed. As far as I can tell, java is working fine, and Vista isn't giving me UAC prompts when I open Firefox.
For the record, the extension is supposed to help java applications load faster, but Sun (the makers of java) say that Vista has it's own pre-loading mechanisms which make it unnecessary. So good work on taking it out of the vista download guys :I
If having the extension showing in your list of extensions with the uninstall checkbox grayed out annoys you, you can delete it through the registry (probably best to do with Firefox closed), and if these instructions don't make sense, then don't try this:
1) Open the registry editor by typing "regedit" (without the quotes) in the search box in the start menu.
2) Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\extensions\
3) Delete the entry named jqs at sun.com (or something to that effect)
4) Enjoy your fixed Firefox
Thanks to Ahaolds for posting this fix on the Mozilla support forums.
Worked like a charm.
