I'm using FF 19.0 on W7.
Hello caribbeandreamer, try to clear Cookies & Cache and check it again.
also could you try disabling graphics hardware acceleration? Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.). Then perform these steps:
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

Can you attach a screenshot?
Use a compressed image type like PNG or JPG to save the screenshot.
If you have increased the minimum font size then try the default setting "none" in case the current setting is causing problems.
Make sure that you allow websites to choose their fonts.
It is better not to increase the minimum font size, but use an extension to set the default page zoom to prevent issues with overlapping text.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
Ok, i cleared all cache & cookies, disabled hw acceleration and restarted - no change. I have not changed any of the default font settings. I'll try safemode next.
See attached screenshot...
Ok, restarting in safemode prevented the problem. Now how do I pinpoint which addon is causing the problem?
If it works in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
If you use extensions (Tools > Add-ons > Extensions) like Adblock Plus or NoScript or Flash Block that can block content then make sure that such extensions aren't blocking content.
I don't use Adblock Plus, NoScript or Flash Block but I'll try disabling and reenabling 1 at a time and let you know which one was the culprit.
Thanks for the quick responses!
