Mullvad Browser almost completely breaks Memex

[tjex]

If reporting a bug:

1. Can you describe the problem and bug in more detail?

Memex is effectively unusable on Mullvad Browser. Login says successful, but Memex doesn't load account / data.
Keybinds don't work.

2. How can we replicate the issue?

• Install Mullvad Browser.
• Install Memex extension.

3. Expected behavior (i.e. solution)

I should be able to at least login.
I understand that Mullvad Browser is a privacy centric browser, but login / account retrieval shouldn't be broken.
I understand that maybe keybinds or overlays may be broken depending on how the scripts are being injected, but overlays (sidebar, quick action bar) work regardless.

5. Other comments

Mullvad Browser comes pre-installed with uBlock and NoScript. I've tried dissabling both of these extensions, but still can't login to Memex or use keybinds. I've also tried with a fresh install of Firefox and installed uBlock, NoScript and Tridactyl (the only extensions I'm using). And everything works fine. So Mullvad is breaking Memex somehow. But how is the question? If anyone can point me towards a setting that Mullvad have as default that could be breaking Memex, I would consider disabling it. It is a modified Firefox after all, so at some point it should be able to work with Memex.

Here is the list of settings that Mullvad implement.

Never mind. Looks like Mullvad breaks many extensions, and particularly ones that require logins...
