I have Firefox 3.6.2 and the links flash but because I use the single click option in Windows I do not have the whack a mole issue.
What happens as I can see is the link should flash when you select it by single click.
Change from Double click to single click in your OS and the Blinking link is a non issue.
In XP go to the control panel/folder options
In the Click items as follows box select Single-click to open an item (point to select) and click Underline icon titles only when I point at them.
In W7 open Explorer (folder icon on bottom left near start button)
Click on Organize select folder and search options
In the "Click items as follows box" select Single-click to open an item (point to select) and click Underline icon titles only when I point at them
This takes you out of the dark ages of double click and into the proper world of clicking once.
What before was the simple action of selecting a file by clicking it once is now done by pointing at it. executing which was done by the double click is not done by single click.
It does take a little getting used to and if you don't like it just go backwards.
