Hello, thanks to all for all the work on this project! I've got a quick question on how to reduce CPU usage of TenFourFox when I'm not actively browsing. It seems like once I get a few web pages open TenFourFox is using a bunch of CPU, even with no internet connection and the windows minimized or in the background. Is there a simple way to pause/suspend TenFourFox without closing/killing it when I'm not actively using it? I've tried a couple process control apps to suspend the process, but then when I resume it some things are screwy so I end up killing the process anyway. The "restore previous session" from the history makes closing/restarting TenFourFox less painful to get all my tabs back, but I'm wondering if anyone has a better way. It seems like "work ofline" would do this.

    This is a problem with standard Firefox as well where background tabs and windows can continue to have active content, using CPU, even though you aren't actively interacting with them. There is an add-on you can try ( https://addons.mozilla.org/en-US/firefox/addon/suspend-background-t... ), but it is highly experimental, and is known to have some problems on certain sites.

    The long and short of it is that Mozilla isn't sure how to solve this problem, and I'd rather not have us work on a half-cocked solution of our own because of the compatibility risks, though I certainly acknowledge the issue.

    I'm testing the "Suspend background tabs" add-on right now. Largely it seems to work as expected. For underpowered Macs it's probably a good solution. It can be disabled without re-starting the browser, in case it's interfering in some way (which it most certainly will at some point). BTW, the guy who makes it is also responsible for AdBlock Plus, so I'm confident the add-on will improve over time.
