I have Mac OS X 10.4.11. Just got inivite to download latest Firefox 4 upgrade. I clicked download, but it then asked if I wanted to save it or download it. Again said download it. It then asked where and had list of applications, i think. I don't know which one to click. When I said to save it in Applications. When I clicked the file in for firefox 4, again it asked how I wanted to open it. Any ideas? Thanks.

Firefox 4 will not work on OS X 10.4, it requires at least OS X 10.5. You already have the latest version of Firefox for OS X 10.4

Hi Mjgfox, I recommend going to the Help menu and choosing "Check for Updates". This will make Firefox update itself to version 4 automatically; that way you don't need to worry about where to save the files or how to open them.

Hope that helps, --Jono Xia, Mozilla
