Why is Control-Left-Click Drawing a Box Around Parts of the Screen?
There was a longer version of this, but when I clicked "Post", I was sent to an "Access Denied" page.
When I Control-Left-Click, FF frequently places a blue border around part of the screen.
Investigation suggests that it is highlighting a TD element and its children. View Selection Source always shows a TD.

Here's an image showing what I mean.
Do you have that problem when running in the Firefox SafeMode?

Don't select anything right now, just use "Continue in SafeMode."
If not, see this:

Yes, it still happens in safe mode.
Actually, I'm not sure it's a "problem". It seems to be a feature of something. I'm just looking for an explanation of what the feature is.

Yes, I know about this 'feature' with a Ctrl left click on certain pages.
You can see it for example on the mozillaZine forum page.
I don't know why this happens, but I assume that it is some accessibility feature to identify certain page elements.
