Does that /really/ take a lot of CPU???

I think it's more likely advertising crap that's constantly phoning home for a 
new
banner, and using complex scripts that aren't always as efficient as you might 
like.
Turn it off with AdBlock Plus or equivalent.

I don't have any trouble with nytimes.com, but I do use ABP.

Or you could do a quick check by disabling scripts on web pages:

Edit | Preferences | Advanced | Scripts & Plugins:
Enable JavaScript for:
[ ] Browser

If that solves it, then the trouble pages have bad scripts and an ad blocker 
will help.



GIF files can take up a lot of time DEPENDING on the age of the CPU
and whether or not there is a graphics card ;-)

Changing the image loop to once did not change the amount of CPU time in 
use, so I changed it back to Always.


Disabling scripts did reduce the CPU time significantly, but also 
prevented the satellite weather loops from running. I turned scripts on 
again, and for now will run the loop only when I'm looking at it; 
currently, I've left it running all the time.


I noticed something odd (to me, anyway) on the NY Times home page. The 
"X" in the location bar that stops the loading/running of a page is 
normally "dim", but every 10-30 seconds will blink red (active). I 
assume that means the page is doing something periodically.


I'll give ADP a try.

Yeah, like many news sites it refreshes at regular intervals. From what 
I can see of the code, it looks like 30 seconds.

plugins.click_to_play

2013-09-17 Thread EE
I just found out that Firefox has changed the way plugins.click_to_play 
works.  It now no longer puts placeholders over individual plugin items. 
 I hope SeaMonkey is not going to do the same thing.  Please, tell me 
that will not happen?


The great thing about plugin blockers is that you can control which 
items on a page will load by clicking placeholders.  Take that away, and 
you lose that control over which items will load.
