Sandbox plugin-container errors exceeding 500 log messages per second.

I've been experiencing computer crashes which have prompted me to begin monitoring the console system log. In doing so, I've noticed that I regularly receive these sandbox message seemingly every time I open a new tab. Regardless of whether or not this is attributing to the crashes, I'd like to get a handle on this particular situation and either repair the sandbox relationship or disable further attempts at accessing entirely. Any assistance on the matter is greatly appreciated.

Does it make any difference if you turn off various sections of the new tab page: Customize your New Tab page to hide or display content.

I assume, although I can't be completely certain, that the only thing Firefox is running in the Plugin Container is Flash. But I can't think of a reason for Flash to fire on the new tab page. Can you think of any connection?

I've disabled everything I could see of Pocket . The only things listed in the New Tab page are Highlights (which only displays recent history) and Top Sites, both of which I do find useful and would like to keep if possible.

to clarify my worries, I'm not so much concerned with the timing of the log messages as I am their volume. Firing off over 500 attempts within a single second to access these systems is pretty excessive. Do you happen to know of any way to make plugin-container or iokit-get-properties... well... chill out?

Could you try completely disabling all plugins to see whether that has any effect? That would be on the Add-ons page. Either:

  • Command+Shift+a (Windows: Ctrl+Shift+a)
  • "3-bar" menu button (or Tools menu) > Add-ons
  • type or paste about:addons in the address bar and press Enter/Return

In the left column of the Add-ons page, click Plugins.

Typically you would have:

  • OpenH264 - for peer-to-peer video communications
  • Widevine - for DRM-protected video
  • Shockwave Flash - the Flash player

If these are all set to Never Activate, does plugin-container shut up?

Sorry for the slowful reply... By the way, I am on a Mac, but I did as instructed and I can confirm that even with all plugins AND extensions disabled, plugin-container is still firing off in excess.
