Some back-of-the-envelope work by users indicates that firefox (logged in) and chromium (logged out) on linux have this problem; firefox and IE on Windows (not logged in) do not.

I should note that I've been having this bug (well, with ctrl-click on my laptop, but think that's the same thing), and I don't have VE enabled. However, this bug's several days old, and I'm pretty sure this has only been happening to me within the past hour. Chrome on a ChromeOS netbook.

Raising importance, this is quite annoying. It's just been reported on [[WP:VPT]] for the second time today.

Fixed in gerrit 70735 which is now merged and will get pushed later today.

I'm not sure how the fix was implemented, but it seems to have started occurring again - this time only in namespaces in which the VE isn't active.

My testing shows that ctrl+click works only in VE-enabled namespaces but middle click works everywhere in Firefox 22.

In Konqueror 4.8.5 (which is apparently not enabled for VE) both ctrl+click and middle click both work only in VE-enabled namespaces.

Gah, bad breakage related to making VE more lightweight - sorry about that. Gerrit 72069 fixes this, according to my local testing - we'll try to get this out today.
