Overlaying Firefox's new Addon Manager

I'm trying to create a conditional overlay for firefox's new addon manager in minefield 3.7 (aka firefox 3.7)

I'm trying the following:

overlay    chrome://mozapps/content/extensions/extensions.xul chrome://greasemonkey/content/addons.xul application={ec8030f7-c20a-464f-9b0e-13a3a9e97384} appversion<3.7
overlay    chrome://mozapps/content/开发者_StackOverflow社区extensions/extensions.xul chrome://greasemonkey/content/addonstab.xul application={ec8030f7-c20a-464f-9b0e-13a3a9e97384} appversion>=3.7

And this works for firefox 3.6, but it does not work minefield.. y?

Edit: even the following doesn't appear to work in minefield, but does in FF 3.6 (I just made the overlay add a blank css file, an dI can find the css file included in FF 3.6 but not Minefield):

overlay    chrome://mozapps/content/extensions/extensions.xul chrome://greasemonkey/content/addonstab.xul

3.7a5pre is less than 3.7, so it will not apply. I think you want this instead:

overlay    chrome://mozapps/content/extensions/extensions.xul chrome://greasemonkey/content/addons.xul application={ec8030f7-c20a-464f-9b0e-13a3a9e97384} appversion<3.7
overlay    chrome://mozapps/content/extensions/extensions.xul chrome://greasemonkey/content/addonstab.xul application={ec8030f7-c20a-464f-9b0e-13a3a9e97384} appversion>=3.7a5pre

It's a bug.
