Title:
Firefox hangs after simultaneously opening Chrome/Electron-based
applications
Status in firefox package in Ubuntu:
Confirmed
Bug description:
When opening Chrome/Electron-based applications while Firefox is open,
Firefox' tab contents stop responding, and it becomes necessary to close
Firefox and reopen it.
This includes:
- VSCode: https://code.visualstudio.com/download
- Atom: https://atom.io
- Chromium browser
Here's a link to a screenshot that shows Firefox with a "loading"
waiting icon on the center of the tab (applies to any other open tab)

This has been happening since Ubuntu 14.04, but my previous report was
quickly dismissed.
I've done fresh installs for 14.04, 16.04 and 18.04, and the problem persists
ever since.
OS: Ubuntu
Release: 18.04 LTS (other 18.04-based distros such as elementaryOS exhibit
the same behavior)
Firefox: 74.0.1, 64-bit (although the problem happens since 32-bit
60.x or even earlier)
Current Hardware: Lenovo ThinkPad T410s: Intel i5 540M processor,
NVidia NVS3100M graphics, 8Gb RAM, 480Gb SSD
# Expected behavior
While Firefox is open, any Chrome/Electron-based application that is opened
works without affecting Firefox.
# Observed behavior
While Firefox is open, any Chrome/Electron-based application that is opened
hangs Firefox, as observed according to the screenshot link provided above.
