I tried I.E.10 but ran into too many compatibility problems so I went back to I.E.9.
There have been other complaints, that I've seen, about problems with browsers other than I.E. I've seen this on some other forums too, such as the Dell community forums.
I installed Chrome but then I started to get some audio dropouts and clicks in Sonar. DPC Latency checker was also showing RED spikes. As it turned out the Google updater, which was installed with Chrome was causing the problems. I uninstalled Chrome but the Google updater remained. I uninstalled it with Revo Uninstaller Pro (paid version) which also searches the registry and has an option to uninstall registry items. After rebooting the PC I checked and I was still getting the DPC Latency spikes. I had to manually go through the system and remove many leftover registry entries and even program files. It was a major mess. But, after I finally got rid of all the Google updater entries and after rebooting my DPC latency was back in the low green area and I didn't have any more dropouts or clicks in Sonar.
