Arial fonts show dingbats on search results and pages with Extensis Suitcase... cannot resolve.
I've read many support posts. I cannot find a solution that works. This does not happen on Chrome nor Safari. I have turned off all findable Arial duplicates in Extensis, etc. I just have no idea where this occurs and I want/need Firefox for my default browser while I run development sites with grid and use Firefoxes Inspector tool.

In case cor-el's first reply doesn't help:
It seems the pattern on that results page screenshot is that bold text is rendered incorrectly, but regular text is okay. Comparison screenshot attached for reference.
There actually are different font files for regular and bold fonts (and italic fonts, and bold italic fonts), so possibly there is a corruption issue or incompatibility if the problem is limited to Arial Bold.

That is not about dingbats, but about switching to a 'last resort' font because of sandbox related issues and can happen if you have fonts installed in other than default location.
This likely means that Firefox isn't able to access the requested font and falls back to a 'last resort' font that shows all glyphs as a '?' or an 'A'.
You can check for sandbox security issues when Firefox has a problem to access fonts installed locally.
You can set this pref to 2 or 1 on the about:config page to reduce the sandbox security level.
- security.sandbox.content.level = 1
- close and restart Firefox to make the change effective.
If '1' still doesn't have effect then try '0' to disable the sandbox.
If this didn't work then undo/reverse the change and reset the pref via the right-click context menu to the default value.
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Thank you for the response! I had tried to remedy this by turning off occurrences via OS utilities, but I have guarded optimism this morning after completely moving suspected duplicate font files into anonymous folders... it currently appears the garbled font has disappeared from Firefox.
I had seen multiple posts per cor-el's response but honestly, my attempts to use the instructions led down a complicated path in Mac OS that seemed to loop into a series of caution modals and warnings with no positive outcomes. Far more advanced than a front-end caliber user can accommodate. But, thank you for responding!! :-)
