This sounds kinda bad but we can't reproduce. Krupa, could you take a look?

On Firefox 70, with all the add-ons the reporter has installed, I wasn't able to reproduce the issue.

@sheelgautam995, do you see any errors in your browser console?

NIing alexa to do some exploratory testing to see if she can trigger this error.

I've discovered that Addons install when browser window is not in fullscreen mode on MacOS.
When browser window is in fullscreen mode, the button do nothing.

I don't see anything important in the browser console. But, I've discovered an interesting bug in the browser console which I will submit separately.


I have managed to reproduce the issue consistently on Windows 10 Pro 64-bit, MacOS Catalina 10.15 and Ubuntu 16 on the latest Release version (70.0.1/20191030021342) exclusively, with the following STR:

  1. Start the browser and enter fullscreen mode (F11 on Win and Ubuntu / Green Expand Icon or Control+Command+F on MacOS)
  2. Go to Add-ons Manager page and click the “+Add to Firefox” button or “+ Install Theme” of any extension or theme from either the “Recommendations”, “Extensions” or “Themes” tabs.

Actual results:
Add-ons are not installed and themes are neither. No errors are displayed in the console.

AMO installation works fine under fullscreen mode on all OSes.

The latest Nightly and Beta are unaffected by this i.e add-ons and themes can be properly installed in fullscreen mode, both from add-ons manager and AMO.

The issue might be related to .

Ever confirmed: true

This seems to work for me on Nightly in fullscreen mode. Sounds like a dupe of bug 1583665 then.
