Cannot install nosript in firefox

[leres]

I'm running firefox 57.0.2 on FreeBSD 10.3 with xorg 7.7. For the last few days I was unable to upgrade noscript. Today I tried uninstalling/reinstalling and find that I can no longer install the addon at all.

Here's what I've tried:

• Exit firefox, remove ~/.mozilla and start it
• Go to about:addons, search for noscript and click install
• Get a popup requesting permission, allow it
• See this console log message:

  1513188165861 addons.webextension.<unknown> WARN Loading extension 'null': Reading manifest: Error processing background.persistent: Event pages are not currently supported. This will run as a persistent background page.

• The plugin is downloaded and then nothing happens
• If I switch to another tab and then go back to about:addons I get a fresh popup asking for permission to install

I'm not finding any reports of this problem so I was pretty surprised when nuking ~/.mozilla didn't solve it.

I set up a FreeBSD 10.3 VM to test this, but I cannot reproduce the problem. NoScript installs and runs fine for me in Firefox 57.0.2 on FreeBSD 10.3.

How did you install Firefox?

I'm installing from the port built on one of my poudriere build servers. I'm using these options:

• BUNDLED_CAIRO
• DBUS
• FFMPEG
• OPTIMIZED_CFLAGS
• ALSA

I just tried uninstalling the firefox built on my server and installed this instead:

http://pkg.freebsd.org/FreeBSD:10:amd64 ... .0.2,1.txz

It has the same behavior. It doesn't seem to matter which box I click on the popup (cancel or add), once I click the box goes away and the "downloaded" bar graph just stays at 100%.

Are there debugging options I can use to figure out what's going wrong?

http://pkg.freebsd.org/FreeBSD:10:amd64 ... .0.2,1.txz

I think that is what I used. (I switched the source to "latest" and then did pkg install firefox.)

I don't know FreeBSD well enough to help further, sorry. If no one else here is able to help, I would suggest asking on a FreeBSD forum.
