I forgot, if you want to know more about Flashblock: <http://flashblock.mozdev.org/>
I like Firefox because of various extensions I use with it particularly Adblock and Flashblock which cuts out a lot of the visual advertorial pollution on many sites. With Flashblock you just get an icon everywhere there would be flash content and if you actually want to see the flash content (say a relevant video you want to see) you just click on the icon to enable that particular flash item. I would think that Flashblock could greatly reduce the Firefox CPU/memory drain. To put it in context, on my iMac (late 2009, i7, only 4GB RAM) I currently have running: > * Adobe Photoshop Elements > * Adobe InDesign > * Firefox > * Entourage > * Preview > * Calculator > * Activity monitor I would also typically open up Word, Safari, Excel without feeling the need to shut anything down. Currently, Firefox has 3 open windows with a total of over 20 tabs open. When researching something, I frequently have more tabs open. As all the tabs are fully loaded and I am using Entourage (to write this) Activity monitor is showing my CPU hogs ;o) are: > 4.8% activitymonitord > 3.5% Firefox > 2.8% Indesign > 1.8% Entourage > 0.9% PS Elements > 0.9% Activity monitor Obviously these figures ramp up as I start using the programs and Firefox can certainly get up there when using it a lot. Occasionally, I do find I overload Firefox when I have multiple windows each with many tabs Firefox starts to get VERY sluggish and will eventually come to a virtual standstill. However, a restart of Firefox and a culling of some of the excess tabs will soon bring it back in line ;o) So, if you actually prefer Firefox, check out the Flashblock extension. By the way, I also use Safari for certain sites typically a few that don¹t play nicely with my locked down Firefox. Horses for courses. Just my 2c worth ;o) Cheers Neil -- Neil R.
