Browser is displaying capital A in boxes instead of text since 56.0.2 update
Ever since the update, most text on web pages I visit have capital A in boxes instead of the actual text. Images attached.
I tried Happy112's suggestion (on another thread) about changing the security something to 1 instead of 3 and it actually made it worse!
I've had to use a different browser since the upgrade, which is a bummer. Would like to use Firefox again.
I'm running on Mac 10.9.5
I hope some Firefox Guru has the answer.
Thanks much.

This is generally a problem with fonts. The recent issue in Firefox 56 related to the security sandbox. With the higher strength sandbox, Firefox could not use "suitcase" or "Adobe Type 1" fonts. Lowering the sandbox level changes the behavior back to how it was in Firefox 55.
If that didn't help -- I believe you need to Quit Firefox and start it up again to be sure -- then there may be a problem of corrupted fonts. To try to sort out which font is the problem, you could use Firefox's page inspector. Here's how:
Right-click (or on a one-button mouse, Ctrl+click) some problem text, then choose Inspect Element. This should open the Inspector in the lower part of the tab with the element you right-clicked selected in an HTML display. On the right side, there is a panel that may show Rules or other data about that element. At the far end of the line that has Rules, Computed, Layout, there is a little triangle you can click to show the full list and select the Fonts panel. Here Firefox should tell you what font it actually is using either at the page's direction or in place of what the page indicated. Do you see a pattern to which font has the problem?
Hi Jscher2000,
I thought I'd replied to your suggestion, but maybe it was in a different thread. Thank you for the cool suggestion as to how to find the font it's trying to display -- seems it's Helvetica Neue. However, I don't know what to do with this info now! I use the font for work and it seems to be fine. I ran some tools to check my fonts for corruption and they're fine.
Lowering the sandbox level makes it worse actually, so I put it back to to 3.
Any ideas?
I think Helvetica Neue is a standard font on MacOS, so I don't know why it would suddenly go haywire in Firefox. Hopefully a Mac person can suggest something specific to try next.
Yes, it is strange and my other browsers aren't having this issue. Thanks for your thoughts -- much appreciated.
In what location is this Helvetica font installed and what kind of font is this (true type, open type or different)?
You can try to move this font to a location where other working fonts are located.
I assume that you did check for font issues in Font Book?
