#26488 new defect (bug)

Ugly Font Smoothing in Firefox Menus

Reported by: miqrogroove Owned by:
Milestone: Awaiting Review Priority: normal
Severity: normal Version: 3.8
Component: Administration Keywords:
Focuses: ui Cc:


When I hover the fly-out menu links in Firefox, the text of the whole menu becomes less bold and appears highly ClearType'd.

The admin bar, and the non-fly-out items do not seem to be affected.

Confirmed, I see this when hovering over adminmenu items in Firefox 25 on Windows XP. It appears to be confined to Firefox, the cause is unknown to me.

The CSS is set to call -webkit-font-smoothing: subpixel-antialiased; in wp-admin.css, and it also has -moz-osx-font-smoothing: grayscale; for a many elements, but Firefox doesn't fully support CSS font smoothing, even with the vendor prefix, per MDN: https://developer.mozilla.org/en-US/docs/Web/CSS/font-smooth

There seems to be a lot of issues with Open Sans and Firefox related to font smoothing. I'm not sure it can totally be fixed unless Mozilla adds CSS font-smoothing (or it gets adapted as a CSS standard)?
