Embedded Gliffy diagrams do not show in Firefox

Question

Firefox is no longer displaying embedded Gliffy diagrams, although the frame shows up and if moused over, the gliffy buttons appear.
If I open them fullscreen, it shows up normally.

Firefox version: 138.0.1 (64-bit)
This is in Linux, but the same issue appears in Windows Firefox.

The same page displays normally in Chrome

Hi @Vanessa Keating

Then it looks like an issue in Firefox, this can be due ot Firefox being more strict on security then the other browsers, are you also in the latest. version.

But yes, it could also be relted to company polies on company hardware.

Hi @Marc -Devoteam- - thanks for replying.

I already tried an incognito window, cleared cookies and cache and turned off all my browser integrations. No difference.

I think it's clear that it's a browser related issue - but is it a case of Firefox displaying incorrectly, or just that Firefox has different, correct, expectations about how Gliffy/Confluence should be working that are not enforced by other browsers?

I'm also wondering if it's something specific about my company environment or whether this is affecting other Firefox users?
