456478 - Marquee tag fails to initiate (if javascript disabled)

Status: RESOLVED DUPLICATE of bug 208864

(Thunderbird :: General, defect)

Description

[Joe Sabash [:JoeS1]]

Since javascript was temporarily disabled, no marquees are rendered.

Prior to bug 453943 checkin, the default marquee worked, but JS had to be enabled for marquees with behavior attributes. See attachment.

cc: martijn for implementation comment.
I wonder why marquee js does not have chrome privileges.

Because there is a huge risk for security problems that way. Especially if marquee bindings would get chrome privileges.

There is bug 208864 for the general issue that marquees are not working when js is disabled.

I'm afraid I can't really do anyting about this. I have some idea about rewriting the marquee code, using -moz-transform: translateX and SVG SMIL (not checked in), but I have totally no idea if that would be feasible.

Joe, JS has privileges based on the Window it's running in, basically.  Certainly XBL JS does.
