It has Java Platform, Shockwave for Director, and Adobe Acrobat and a couple of others I’ve never seen. Also, Wild Tangent Detector.
As for the question mark, I was confused by what it shows. If I do this stuff early enough in the day, I can usually muddle through, but I’ve already been awake for eight hours, so my thinnin’ is a little off, Baba.
(CFIDS at work. Sorry if it sounds like a litany...)
Depending on what the others are they probably go with whatever was loaded on the machine. Wild Tangent for instance comes with some preinstalled games. Of course if you don't play those games it's just bloat, but it does 'phone home'... Here's some info on Wild Tangent: "Wild Tangent is a software company that specializes in 3D video games played over the Internet. It has recently joined with AOL to create games for AOL’s Instant Messenger games. Wild Tangent games are not spyware but they do gather information about the user’s computer and send this information to Wild Tangent. Wild Tangent software is not conventional in its install process, so sometimes it does not uninstall as easily as other programs."
On the page listing the plugins, did you click the blue line at the top that says 'Check to see if your plugins are up to date'?
Surprised it has Shockwave Director on it but Adobe Flash (also listed as Shockwave Flash) isn't listed, but then if it has some of those Wild Tan games on it, they use Shockwave, so I guess that makes some sense.. You can get Flash here. This link will take you to the Flash download page.
Oh looky, a thunderous storm..
As for the question mark, I was confused by what it shows.
If you click the ? you should get a screen with a list of 'help' items. At the bottom of that list should be 'About Firefox'. If you click the 'About Firefox' you should get a popup box that among other things will have the FF logo, the ID (Firefox) and the version number right under the Firefox name. It will either indicate 'Firefox is up to date' or will let you know a newer version is available (and will probably start downloading it if there is since that is the default setting.)
Now that I've confused you enough for the remainder of the day, I'll go back to re-waterproofing my boots. The laces broke - one about a month ago and I 'spliced' it with a square knot - and the other one this morning so after I remove the damaged laces and relegate them to cat-toys, and before I install new laces, I have a 'clear' boot to smear squished mink on.. ;-)
