[GreaseMonkey] Userscripts not applied to iframe

[pejakm]

I'm not sure if this is a feature or limitation, but some scripts rely upon it.

Example: I made this script to apply GMail "Ocean" theme to RoundCube webmail (Login: demo1@demo.roundcube.net - demopwd).

How it looks in QupZilla: https://mediacru.sh/y-TDSqfbos64
How it look in Opera 12: https://mediacru.sh/spOEoWd6VwgR

Also, the script is not working in Settings, Identities and Responses tabs, and I can't figure out why, there's no report of any kind in console.

The link to script is not working (403). Can you please paste it somewhere?

[pejakm]

Sorry, wrong file permissions. Fixed now, but here's a paste:

Try it with GM_addStyle() function to add a style to page (instead of your code)

Not working. Plus, I doubt GM_addStyle is supported by Opera. However, I did notice the iframe was transparent for a short period of time, until the page loaded completely. Any thoughts?

The thing is, userscripts actually are applied to all frames, including iframes ...
But only when the main frame finishes loading, it does not track other frames.

I still don't know why it doesn't work on those other pages.
