(Core :: Graphics: Text, defect)

Attachment: mdn.png

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/600.5.17 (KHTML, like Gecko) Version/8.0.5 Safari/600.5.17
Build ID: 20151203004003

Steps to reproduce:

- Launched Firefox

I removed Firefox (newest non-beta version) and tried installing the newest Developer edition instead 44.0a2 (with a new profile). It still happens, both in webpages and in add-ons.


Actual results:

Lots of missing fonts/letters/symbols (see screenshots)


Expected results:

Fonts shouldn't be missing.

Here are two extra screenshots - one from an add-on (uMatrix). It happens both with and without add-ons installed.

Sorry, attached the same screenshot twice. I intended to add from Github:

I could not reproduce this, though I am confused about the correct component.
Graphics:Text ??? or  Layout:Fonts

Feel free to move If I am wrong

T.Toft: Are you running the 32-bit or 64-bit Windows build?

If you're currently running the 64-bit version, please test with the 32-bit build and confirm whether the problem still occurs.

I tired uninstalling and are now running Firefox 42.0 (32-bit). That fixed it.

Comment 6

[T.Toft]

Disregard my last comment. I looked at github.com as a test and it seemd to be working fine. I tired MDN and the "fonts" are now missing again* 


*- Not sure if it is a font or images?

Comment 7

[Jonathan Kew [:jfkthame]]

They're icon fonts (e.g. the "octicons" font used on Github), and apparently in some cases they're failing to load for you.

I think I've seen several reports lately of fonts failing to load in the 64-bit Windows build.

cc'ing jdaggett for any insight.

FWIW, I can reproduce this on MDN as well. I cannot reproduce this in a new profile so perhaps there's something I've changed that triggers this. I'm not sure it's related but I see the following error in the Web Console:

Sorry, that cut off some of the log. The entire message is as follows.

Okay so now I've done the Reset Nightly dance and reinstalled my addons but the bug does not reproduce, nor do I see the errors in comment 9. That leads me to believe either some corrupt cache or some preference change triggered it. I have the profile backed up if someone wants to take a look at it.

Comment 11

[[:Towkir] Ahmed]

I have also seen the errors coming up in the console and security tab. some site (from where the fonts were fetched) blocked the visiting site to access the fonts. 
though this is random

Comment 12

[T.Toft]

I'll try the nightly later today and report back. Is there any way to see a log of what is blocking the icons in add-ons, since I'm also seeing it there?

Comment 13

[T.Toft]

I'm having a "crash on new tab" problem also. Maybe it is related and corrupting something?
