Im creating a FF extension for private distribution (I dont want it listed on the FF extension site). If I use "\r\n" in my manifest.json "description" I can create a multi line description that displays as expected when I click on the preferences for my extension. The problem is that on the Add-on summary page (where all the installed extension are listed) the description shows the first 40 or so characters of the description (all of line 1 and then as much as will fit of line 2). I want to only show line 1. I see that with extensions that are published the first line can be short and displays in the summary list, then when the preferences are displayed the first line is displayed and additional lines are displayed. Any way to do this?
