Accessibility: 14.x pop-up menus impossible for blind user, 12.x was usable

• Usability
• Regression

I'm totally blind.. I'm using firefox on Linux with Gnome Orca as a screen reader, although I'm fairly sure the Windows screen readers won't work any better with this.
There are a number of cases where there is an action link next to an object such as:

• Users on the admin user list
• Blogs on the list of blogs

When this link is focused (or presumably mouse-overed), a pop-up window appears with a set of actions that can be clicked on.
There's no way for a blind user to select one of those options. I can ask the Screen Reader to focus on one of the links in that pop-up, but since I'm focusing there not moving the mouse there, the pop-up disappears.
Even disabling the page's styling is insufficient to get to the pop-up in an area where I can click.
I'm not familiar with Bootstrap enough to try and suggest a fix.
I'd be delighted to work with someone to figure out what fixes would work, exchanging patches and the like until we find something that is visually appealing but works better.

For many actions, you can click on the object and get to a details view where you can also perform the action. However there are a number of things where this doesn't work:

• Administrator force-confirming the email of a user
• Editing object permissions of a blog
• Editing or removing an external wiki

There are probably others but those are the main ones I've found so far.

The pop-ups at the top of the page, for example the one that opens up
the selections with wizards, controll panels, etc. And the pop up
containing edit/remove/monitor on a wiki page are both fine.
