Actual behavior

Every 2nd click of the M-A C toolbar button results in a partial expansion of the menu. Every alternate click results in the full menu.

Expected behavior

Every click of the M-A C button should result in the full menu displaying.

Steps to reproduce

1. Click on toolbar button - see menu display
2. Click a 2nd time on toolbar button - only the top part of the menu is displayed

Notes

This issue seemed to start when upgrading to FF75.

1. Based on Quicksaver's Tab Groups page, support has ended up to FireFox 57 only, you may remove this add-on. You can try opening M-AC again after removing it. If it still has problems, then read below.

2) Have you ever edit containers.json? Making minor errors causes issues: #1707

You can read my reference for more info about editing containers.json & suggestion add-on for tab groups.

Hi there

It seems this issue has resolved it self or was only a temporary issue. The drop panel is working on each click. now.

I can't recall specifically about containers.json but I have a vague idea that yes there may have been some editing in the past due to a previous issue.

I'll remove Tab Groups nonetheless. Thanks for your reply and help.
