No Password Input Box on Tor with Mate/Ubuntu

[lizardintelligence]

The lock window doesn't seem to be rendering correctly on the latest Tor version (Firefox 52.5.2). It is missing the input box for the password. It is also missing the lock button icon even though the button works. I've tried uninstalling/reinstalling both the extension and Tor with no success.

For some reason, it works fine for Firefox 52.5.2 on the same machine. It also works fine for Tor on a different Windows machine. I know Tor isn't officially supported, but I'm hoping other people figured out a fix. I'm assuming it is something in the Tor settings since it works for just the base Firefox.

Turn on debug in MP+ options -> help and restart browser, then lock the screen. See if any errors shows in browser console.

Also as I understand, Tor default settings don't allow use of master password at all.

The only error I get is when I login into master password when I start Tor.

XML Parsing Error: syntax error
Location: jar:file:///home/ehou/tor-browser_en-US/Browser/TorBrowser/Data/Browser/profile.default/extensions/https-everywhere-eff@eff.org.xpi!/rules/default.rulesets
Line Number 1, Column 1: 1 default.rulesets:1:1

The login/logout feature of master password works because it uses the pop up window for password input. Only the lock page input window doesn't seem to be rendering correctly (and the lock icon doesn't render either, but I don't if that is related).

Below is the whole debug file from when I start the browser to when I lock it.

I'm able reproduce this on Linux Mint.
What's weird is that for whatever reason any style MP+ adding to the application, are totally ignored, but there is even weirder thing yet: in Developer Toolbox (CTRL+ALT+SHIFT+I), it doesn't show ANY style on any of the MP+ elements. Normally it should show at least the default styles, it's like toolbox is choking on it.
