swf files from my local file browser, instead of opening and playing these files, Firefox asks me if I would like to save them or open them. swf files, I am having another issue, one I have read about on other threads, but it seems it seems to be less easily understood: Now, after completing the procedure to allow local. (3) Double-click the plugins.http_https_only preference to switch the value from true to false (2) In the search box above the list, type or paste plug*ht and pause while the list is filtered Click the button promising to be careful. (1) In a new tab, type or paste about:config in the address bar and press Enter/Return. If you want to revert to the previous behavior: Only SWF files retrieved on or addresses are played (not file://, ftp://, etc.). There is a new security setting in Firefox 55 that supersedes everything else. I followed the instructions given earlier in this thread to allow local files: I'm using the latest Firefox Beta 20.0 on OSX Mountain Lion 10.8.2, and my version of Shockwave Flash is 11.6. have a question concerning local. So anyone care to venture a suggestion as to why this happens? I thought this is unnatural, especially because from what I've read about NPAPI, NP_Initialize is meant to be called by the browser only once. I've tried investigating through CPU sampling using Xcode's Instruments.app, and what I've found odd by walking down the sampled call stack is that about 80% of the CPU usage seemed fishy, and was due to exactly 4 recursive calls for NP_Initialize (see picture for one of the 2 call sites where this happened).īoth sites where this is happening (and not much else?) are inside the stack tree of 0x10fb8ec66 > 0x10fb93947 (in this sample).
That worked fine for a while, but at some point playback started skipping so I decided to investigate. Like many people before myself, I'm having problems with Flash bringing down an entire CPU core (specifically, one of the threads is always using up 100% CPU).įlash is probably running on more than 1 page (I'm using a lot of tabs), but what seemed to start this CPU usage was a bit after I started streaming a movie.
