I just noticed this morning (was fine last night) that the all plus and minus icons on the whole site are showing up as little boxes with numbers and letters in them. Using Firefox version 25.
I tried using it in safe mode with all addons disabled, but the problem still occurs.
This issue is not present in Chrome.
Just wanted to know if others are seeing this, or if it's somehow a problem on my end.
Thanks
Working for me on FF 25.
I had a look in about:config to check for font settings.
For some reason, the setting "gfx.downloadable_fonts.enabled" was set to false. Changed it back to true and it's showing up fine now. Yay! I guess this could help others who may have the same issue too.
No idea how it turned itself off in the first place though. Jolly odd :|
I normally have the "Allow pages to choose their own fonts" option in Firefox disabled. This causes a similar issue. Allowing the page to choose its own fonts brings the plus and minus icons back.
We moved to FontAwesome 4 for the icons in this morning's update, and it looks like your Firefox is not picking up the fonts? Tried reloading? Certainly works when I tested with FF 24/25.
Maybe some extension is causing conflicts?
You can also open up web developer console (Ctrl+Shift+K) to see whether there's any error message.
