Desktop Click to play blocks Silverlight - prompted to Install


(Core Graveyard :: Plug-ins, defect)

Windows 7
Not set


(Not tracked)



(Reporter: jmjjeffery, Unassigned)




Open about:config 
Enable: plugins.click_to_play
Visit a site with Silverlight - 
Click Visit now on the Demo Stock Analysis Chart

Note: You are prompted to Install Silverlight, even though its already installed. 

Testing on Win7 x64 using hourly build m-c win32 cset:

Silverlight 5.0.61118.0
Same thing happens for me with Flash on Linux.

Should that be another bug? It's probably the same root cause.

This is particularly bad because you can't play this content at all - you're prompted to install the plugin and no click-to-play UI is shown.
Not working here too on Windows 32 bit.  Adblock Plus and Flashblock are fully removed.


Open Firefox
Go to this link:
Tap here to activate plugin 
No results.
After re-reading, the Windows 32 bit bug is different and should likely be broken off as a separate bug.
Same with Java.
-> Click the "play free now" button (note: it's a Flash button, hidden by the click to play UI)


Click here to activate plugins

A plugin is needed to display this content.
Install plugin...
I.e. both the click to play and plugin finder service UIs are shown.
Thanks for this! too

i also have traded Flashblock for plugins.click_to_play;true

But by when it will be stable enough to test?
will it have the option to control(enable on demand) for all types of plugins?
& what about say a page has two flash player windows but want to play only the second one
will it be possible ? (flashblock allows this)
Runescape as noted in comment #4 , and Silverlight are now working OK with Click-to-play.

Well, darn when I tested using an hourly build bug 749455 was still in the build, its since been backed out and your Runscape is back to asking for a plugin, or it only wants 1.6 u31 java, I have SE7 U4
Click-to-play notification is properly displayed on silverlight pages.
Tested on:
Verified fixed on FF 15b6 on Win 7 x64, Mac OS X 10.6.8.
