Created attachment 327274 [details] Multipart with attached html When viewing multipart messages "inline", text parts can be obscured by styles in the html parts. STR: Set view "message body as" original html Set view attachments inline Open the included eml Result: The text part is partially obscured by the attachment body style. Bug 18427 addressed this by offering the option to view message body as simple html, and it works well. But I see no "use case" to ever allow any background other than white for text divs. The attached userContent file forces a white background for all text divs. I propose that the affected divs be set to white natively, as the default style. See the attached screenshot when the userContent.css is applied.
> But I see no "use case" to ever allow any background other than white for text divs. The user can have set up (e.g.) white-on-black as default. I agree it's annoying of course, but I'd say duplicate of bug 31052.
I think bug 341059 really goes to the heart of the the problem, but dupping to 31052 Nobody wanting to touch libmime, maybe opening attachments (viewable ones) in Tabs, might be an easier implementation.
