Firefox icon has a white “no” symbol (circle with diagonal line from top left to bottom right) superimposed over it. Clicking it yields: “The application ‘Firefox’ cannot be launched” followed by: “-10661”

I’m a novice and a Mac user. Don’t know computer lingo. About a week ago, while working at computer, I received repeated unsolicited messages, presumably from Firefox, to update to Firefox 4.0. I attempted to comply by clicking, but maybe clicked something wrong and now can’t open Firefox. Hope I don’t lose all my bookmarks. Advice welcome.

Possibly unrelated - highlighting the icon then clicking “Get Info” yields “Kind: Application (Intel)”. Only mentioning this because, being an “iMac G5 / PowerMac8,2 / PowerPC G5 (3.0) / Version 10.4.11”, this computer doesn’t have Intel processors.

Thanks

Thanks very much, edmeister. I *thought* it might be because it’s pre-Intel.

p.s. I think I've now successfully downgraded back to Firefox 3.6 and retrieved those important bookmarks - fingers crossed, knocking on wood, etc...
