Steps to replicate:

1. Start Confluence without developer mode
2. Using Firefox 30.0 or 32.0 to create a new page in Confluence.
3. Insert a table into that page
4. Save the page
5. Edit the page
6. Click 'Insert' drop down in editor menu bar.
7. Scroll down the options

Result:

The first two options (image and link) can be highlighted and selected, but the rest of the options in the drop down do not highlight and cannot be selected.

Workaround:

Within the editor, where you want to insert a macro enter an open curly brace '{' this will bring up the insert dialog and allow you to insert a macro.
