Window popups on Google Sheets don't work

Prerequisites

• Can you reproduce the problem in a fresh firefox profile with only ClearURLs?
• Are you running the latest version of ClearURLs?
• Are you have changed settings under about:config?

Description

ClearURLs appears to block certain window menus on Google Sheets. For example, Ctrl+H is supposed to bring up the find and replace window, but nothing happens when it is pressed. This also happens if the menu is manually clicked on using the mouse via Edit -> Find and Replace. This appears to only affect Google Sheets and not Docs or Slides.

Steps to Reproduce

1. Open up a sheet you have access to on sheets.google.com
2. Use the menus to navigate to a function which brings up a menu (find and replace)

Expected behavior: This brings up a window popup asking what to find and replace

Actual behavior: Nothing happens

System

• Version: 1.21.0
• Platform: Windows 64-bit
• Country: Helsinki (Finland)
