My iMac: Firefox (3.6.3) 27" iMac 2.8 quad core i7 12gb of memory running OS/X ver. 10.6.3 DSL: 6 mbps/768 Kbps Hardwired DSL modem connected to iMac via ethernet cable The iMac is screaming fast except for the Firefox app, the longer I run it the slower my internet is. I have tried disabling the plug-ins as well going to Preferences=>Privacy and setting "Remember my browsing history for at least" to 5 days. This hasn't really helped. I have confirmed that the DSL is running properly, even had a AT&T tech out to confirm it. I am new to MAC so any help would be appreciated!
