Cannot continue past the about:config warning

[Driftini]

Firefox version 126.0, Echelon version 1.2 build 411.
When opening about:config, I get the usual "be careful" disclaimer but clicking on the button to continue does nothing.

The devtools console shows the following upon clicking said button:

ReferenceError: can't access lexical declaration 'gPrefBranch' before initialization
    ShowPrefs chrome://userchrome/content/pages/config/config.js:343
    oncommand about:config:1

I think I should also mention I'm not using the patched xul.dll as I'm on Linux, I'm not sure if that's the issue since I haven't tried replicating the bug on Windows with the patched DLL.

weird, this used to happen to me but not anymore, are you using the latest version?

Yeah
