Opening a page with an embedded flash movie what uses flashvars, flashvars not always passed to the movie. 

Reproducible: Sometimes

Steps to Reproduce:
1. Open a page with embedded flash movie what uses flashvars.
2. Refresh the page some times.
3. 
Actual Results:  
Flashvars are not always passed to the movie.

Expected Results:  
Flashvars should always be passed.

Disabling crash protection solves that problem (using the method described here: http://kb.mozillazine.org/Plugin-container_and_out-of-process_plugins).

Used a single flash variable like "lang=en".
Tried embedding both using HTML tags or Javascript classes (runactivecontent and swfobject), same results.
No adblocker plugin installed.

A link to a page showing the problem, or an attachment showing the problem, would be very helpful.

In bug 563361 they said they noticed a similar issue, although it turned out to be unrelated. We are almost certainly passing flashvars to the NPP_New call correctly in all the cases I've seen. Flash may have some sort of race condition where they are not passed to the actionscript at the right time.

Are you using <object> or <embed> to embed the movie?

Clearing 2.0 nomination for lack of detail, please renominate if we can come up with a better testcase or at least a demonstration.

Resolving old bugs which are likely not relevant any more, since NPAPI plugins are deprecated.
