Description

Strangely, the text on the reply button in our bug tracker is not visible with Tor Browser based on ESR45. I have no such issues with 6.0a4. The security slider setting does not matter. This is on a Linux box.

This is related to our font fingerprinting defense. Commenting out

export FONTCONFIG_PATH="${HOME}/TorBrowser/Data/fontconfig"

solves the problem for me.

If I "inspect" the "Reply" button it and look at font-family under the Computed (style) tab, it says

input[type="submit"]> -moz-use-system-font

and indicates that this style setting comes from resource://gre-resources/forms.css. Interestingly, this font-family setting overrides one provided by tor.css (in the content page).

On my (Ubuntu/xfce4) system, the "Reply" text is visible, however. The "Fonts" tab indicates that it is rendered in Cousine, which is bundled with Tor Browser. Georg, what OS/desktop did you see this problem?

On several different ones, e.g. on an Ubuntu 14.04 with GNOME or an Debian testing system with XFCE. Would it help if I set some debugging env vars to see what is going on within the font code in Tor Browser to debug this? If so, what would help here?

I wrote a fair bit about this problem in the ticket over here: https://trac.torproject.org/projects/tor/ticket/18172

Actually, more things are broken in Trac in Linux TBB than just the reply button not being visible. I'm not able to view the "bold" "italic" "link" or any other icons above the box that I'm typing in right now. I'm assuming others are having the same problem.

The issue seems to be related to a number of very commonly used dingbats not rendering in Linux TBB. #18364

As you can see at this page, a lot of dingbats don't work: http://danshort.com/HTMLentities/index.php?w=dingb
