Die hard Pulse Messenger user for Android, just started using the web extension last week in Firefox.
Works and all, so far working pretty great via Firefox addon, however, PLEASE fix the scaling issues with the toolbar button view.
If you click the icon to open the small frame to reply or use the app in Firefox Quantum, the text is too large, and part of the new message/reply button is cut off the bottom of the page.

even trying to zoom, or set a custom style-sheet does not resolve the issue.

Please advise any potential work around, or if possible please implement a built in scaling/zoom option then this will be perfect!
