Image View V3.4.9 doesn't work in TB 140.7.0esr (32-bit)

[msr986]

I downloaded 'Attachment Viewer' V3.4.9 (dated January 16, 2026).

When I click on 'img-view' the extension opens a blank window with no content.

I am running Thunderbird 140.7.0esr (32-bit) on Windows 11 25H2 Build 26200.7623

Hopefully this can be addressed.

Thanks!
