[Solved] Dialog box display issues Firefox

DWL-SDCA
Today, after a restart of my computer, I noticed problems with the Zotero Firefox dialog boxes that appear 1) during the download/import of an item from a click on the address bar icon; 2) the right-click transform text box and 3) the dropdown menus from Zotero buttons such as the gear button. Please see the following images and make suggestions.

What I tried:
Restarting Firefox didn't improve the display.
Restarting the computer again didn't improve the display.
I changed the Zotero Preferences font size and again restarted Firefox but although the Zotero font changed size, the problems remain.

Mostly, this is annoying but the drop-down menus aren't complete and the options at the bottom aren't reachable.

Is there a "hidden" Zotero setting that I can change to improve this display problem? I don't find similar issues with websites that have drop-down menus.

    I don't think we've ever seen that. You're saying that happens even if you reset Zotero to the smallest font size from the preferences and restart Firefox? Or does it just happen at the larger sizes?

    Actually I doubt this has anything to do with the Zotero font size — from the looks of it, even the Actions menu, which is just a standard Firefox menu, is both cut off and in the wrong place.

    Disable your other Firefox extensions. If that doesn't help, try deleting or moving localstore.rdf in your Firefox profile directory. (That will reset your Firefox window settings.)

    This turned out to be a known but rare Mac Firefox issue. (The only Firefox extension I have is Zotero. I have the most up-to-date non-beta versions of the Mac OS, Firefox, and Zotero.)

    It was suggested that I change the default setting of
    layout.css.devPixelsPerPx. from -1.0 to 1.0 then quit and restart Firefox. After the restart, go back to the config setting and return to the default -1.

    Poof! Back to normal. I didn't believe that would work but it did.
