643986 - Preferences panel layout for extension is broken only on Mac OS X

Status: RESOLVED INVALID

(Firefox :: Extension Compatibility, defect)

Description

[Tom Doan]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.151 Safari/534.16
Build Identifier: 3.6.15

As you can see in the screenshot, the bottom part of the window is not showing, and there is no way to scroll down to that area. The preferences panel shows up fine in Firefox 3.6.15 for Windows and Linux though. There seems to be a XUL rendering bug in Firefox for Mac.

Reproducible: Always

Steps to Reproduce:
1. Install this extension: https://addons.mozilla.org/addon/262804/
2. Open the preferences window for this extension
3. Go to the Form Fields panel
Actual Results:  
The bottom part of the window is not showing, and there is no way to scroll down to that area.

Expected Results:  
The Form Fields panel is supposed to look like what you see in the screenshot on the AMO page (with the 6 action buttons below the table).

I can reproduce the issue also on Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0) Gecko/20100101 Firefox/4.0.

If I fill the form fields with text fields generated by the add button, when filling the form, the last line, the one with the add button, will disappear.

Legacy extensions are no longer valid in Firefox 57, closing.
