I have MacOS 10.5.8, since two Firefox updates ago, my allowed pop-up windows are no longer accessible-I can see them when I look for all open items (Exposé) but nothing happens when I click on it. If I don't use Exposé, the window isn't visible at all.

Question

I block pop ups except for allowed sites, but on the allowed sites, the pop up windows don't appear unless I use Exposé, then when I click on the one in Exposé, it just returns to the open Firefox browser.

Hi Tracy,
I don't suspect Malware yet, Id guess Disk corruption or failing Hard Drive with Files not found.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."

Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
