Tested with as a VirtualBox guest machine, using the default Lumina desktop environment. UNSTABLE repo preferred.

Not reproducible with ; no crash.

Reproducible with , with a new profile; moments after first presentation of the FEBE Options window, Waterfox crashes.

It's important to note that FEBE is not as it does not run correctly in a multi-process environment. The browser(s) should already know this and set the browser.tabs.remote.autostart preference (in about:config) to false.

Make sure this preference is set properly before attempting to open FEBE options.

As promised:

GhostBSD11.1-mate-amd64.iso from http://www.ghostbsd.org/download can run a live session in VirtualBox, and includes Firefox 56.0.2. Whilst a live session is good enough to reproduce the crashing, I have no idea whether it'll be good enough to debug.

(Beyond a live session: I had less success with an installation of GhostBSD in VirtualBox – no GUI, networking not working, and so on.)

Reproducible with Waterfox 56.0.3.65_1 on GhostBSD.

Chuck, if you'd like to verify the bug on GhostBSD in VirtualBox, I found a simple workaround to X not starting. The whole caboodle, to include installation of Waterfox:

at the login prompt, command line, log in as root
pkg install waterfox
pkg upgrade
cd /etc/X11/
cp xorg.conf.vbox xorg.conf
shutdown -r now

Hint: at about:preferences#general in 56.0.3.65_1 you'll need to manually disable multi-process.

As of now, I can verify that FEBE v8.9.3.1 works with both Firefox v56.0.2 and Waterfox v56.0.4 under Windows 10. And FEBE v10.2 works with Pale Moon v27.7.2 (Windows 10).

At one time, FEBE was working fine with Ubuntu but I've haven't tested it recently. I know it does not work with Waterfox under Linux Mint 18.3. I've had limited success with OS X but don't remember with which versions and/or browsers.

There are simply too many nuances with different browsers running under different OSes to test all combinations. And I don't want to have to maintain several different versions of FEBE for each combination.

FEBE for Fx will probably not have any more updates. I will, however, try to maintain the Pale Moon version as well as a version for Pale Moon's Basilisk. But the focus will be on the Windows versions.
