Affected versions

• 78.0esr, 78.0, 79.0a1 (2020-06-25);

Affected platforms

• macOS 10.15.5

Steps to reproduce

• macOS and Firefox themes are set to Dark

1. Launch Firefox and install "Tumblr Post" (https://addons.mozilla.org/en-US/firefox/addon/tumblr-post/)
2. Access about:addons
3. Access the Preferences page for the addon;
4. In the sub-panels click to open the [Published] dropdowns;

Expected result

• dropdown menu options are readable;

Actual result

• dropdown menu and text is black until hovering over;

Regression range

• not a regression;
• builds prior to 68.0a1 do not allow install of the addon, so can't get a proper check on builds before it;
• as it stands, suspecting it as either on the publisher's side or something overlooked when the current Dark Theme was implemented;

Additional notes

• attached recording with the issue;
• as a check, issue does not reproduce on Windows 10/Ubuntu;
• since it's somewhat of an edge case and might be limited to the addon css-setup suggested severity for this is S4.

To investigate.

Confirmed on Windows 10 as well with a dark theme. On top of that, positioning for the popup seems to be off, which probably means we're not setting some browser element attributes correctly.

The severity field is not set for this bug.
:mixedpuppy, could you have a look please?

Hi Alex, could you re-verify this to double-check if it is still happening?
if it is not reproducible anymore, could you run mozregression to find the bug that fixed it?

Thanks!
