User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0

Steps to reproduce:

Install any webextension with a toolbar icon and an attached popup. Click on the extension.

This is with firefox 64.0.2 on Linux Wayland through gnome3
Same issue affects running through X11 on gnome3

Actual results:

The extension popup remains in its initial size and does not expand to fit the content.
When debugging the extension, I can see the DOM elements being created just fine within the popup view, only any attempt to also resize that popup would not be honored.
For example I can set the background color and the small popup would reflect that just fine.

Expected results:

The popup resizes to fit the content. This used to work and also still works if the extension icon is move do to the overflow menu.

Hi,

I cannot reproduce the issue on Ubuntu 16.04 using the latest Nightly 66.0a1 (20190128092811) or Release 62.0.2.

Can you tell us which add on are you having the trouble with or the issue is present regardless of the add on installed?

Could you please retest using a new clean Firefox profile (https://goo.gl/AWo6h8), this way we can exclude if it is a preference setting issue.

I'm also assigning a component to get a start on this, if considered wrong, please feel free to change it to a more appropriate one.

Hi,

thanks for the response and the hint about the clean Firefox profile, I wasn't aware of that feature. Starting with a clean profile the issue is indeed gone and I am also unable to reproduce this.

What is the best way to isolate this further, the about:config page has a lot of custom set properties it seems.

Best,
Johannes

Hi again,

by chance I actually found the root cause setting in about:config which causes the issue.
I've set apz.allow_zooming to true in an attempt to make further use of my touchscreen.

I will close this then, sorry for the noise.

Best,
Johannes
