Waterfox does not display user profile info properly on QRZ.com with uBlock Origin installed

[willbprog127]

Describe the bug
Amateur radio operator profile information does not show up in Waterfox when using uBlock Origin on QRZ.com. This is with a completely new Waterfox profile. Using a completely new profile in Firefox with uBlock Origin works fine, so it does not appear to be only a uBlock Origin problem.

To Reproduce
Steps to reproduce the behavior:

1. Rename your current Waterfox profile to something else (just for testing)
2. Start Waterfox
3. Go to the Firefox add-ons page and install uBlock Origin
4. Go to https://www.qrz.com/db/N6ZN
5. Observe that there is no user profile information for N6ZN under the 'Biography' tab, even though the footer for that section shows 1067 bytes currently being used for the Biography (meaning it's not an empty biography).

Expected behavior
N6ZN's biography information should be displayed.

Desktop info

• OS: macOS 10.14.x, MacOS 10.11.x
• Waterfox version: 56.2.12 (64-bit)

Additional context
Although I'm not 100 percent sure, it appears this site is using Javascript and JQuery to synthesize an iframe to display the user's information. This works fine on Firefox with uBO but obviously not on the current Waterfox.

This bug is worrisome, because what if other content on other sites is not being displayed due to this bug? I do a lot of research, especially for computer programming information, and this could omit important information I need.

Thanks! 👍

Update: I guess that's the fix => https://bugzilla.mozilla.org/show_bug.cgi?id=1379148, I'll test and add to PR.

@grahamperrin GitHub doesn't like links, sometimes they block users for too many links (they consider a bot).
