1666040 - Flash Player content on Mac OS has wrong scaling (zoomed in)

Status: RESOLVED DUPLICATE of bug 1667267

(Core Graveyard :: Plug-ins, defect)

Description

[Kevin Jackson]

Attachment: FF80 vs FF81.png

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.0 Safari/605.1.15

Steps to reproduce:

[Tested on Mac OS Catalina 10.15.6 using Flash Player 32.0.0.433 NPAPI (both debug and non debug versions)]

1. Open Firefox 81 (64-bit) and navigate to https://get.adobe.com/flashplayer/about/
2. Click on Flash Player content to activate (hero image or version block).
3. Click Allow on Flash Player security prompt.

Actual results:

Note that content is zoomed in significantly compared to Firefox 80 (64-bit), making Flash Player content unusable (most of it is outside the bounds of the containing tag).

Expected results:

Flash Player content should be scaled at 100% (or whatever browser scaling is set to).

I can reproduce this on Mac OS X Catalina, but not on Windows 10. I've updated the title to indicate this bug seems to be Mac OS X specific.
