Since upgrading my 12” laptop and G5 to Tiger 10.4.7, Firefox 1.5.0.6 no longer processes clicks on certain links. For example, in Amazon, after clicking on Your Account, none of the links on the account page work. Each one normally requires a popup window so I can enter my user name and password. The same page worked fine before the Tiger upgrade, and my Firefox preferences do not block pop-ups or any scripting. I also tried it with my Paypal account, and the links leading to a pop-up entry window didn’t work there either. I have a Panther 10.3.9 install on another hard disk. Firefox works as expected in Amazon, etc. with the G5 when booted from Panther.
I have deleted preferences and tried earlier versions of Firefox (to 1.5.0.1). I have done a completely fresh install of Firefox without extensions after fully deleting Firefox and the Firefox folder in Application Support. Nothing works with 10.4.7. But Safari and all other new browsers I tested still work with Amazon, etc. as expected in 10.4.7, and all versions of Firefox I tried in 10.3.9 work correctly.
I’m stumped. Anyone have any ideas?
Since my original post I discovered that only links leading to an encrypted https page have the problem. Also, trying a different user on the same machine (tried it on both computers) didn't have the problem. Since I already deleted the Firefox pref folder, it must be a user setting somewhere else. But Safari works...so how could it be my user?
Perhaps Firefox has additional prefs besides the ones in the app support folder?
