Hi! Sometimes Firefox is very slow. When looking in the Windows Task Manager I see it uses 99% of CPU. Memory usage is 148.260 K. What is Firefox doing? I have Windows XP Sp 3. Version 5.1.2600 Service Pack 3 Build 2600 Processor x86 Family 15 Model 4 Stepping 9 Genuine Intel ~2800 Mhz BIOS Version/Date American Megatrends Inc. 1012.001, 28.03.06 Total Physical Memory 1.536,00 MB Available Physical Memory 799,89 MB Total Virtual Memory 2,00 GB Available Virtual Memory 1,96 GB Page File Space 3,35 GB

Thank you for the answer! :)

Kind regards, H. Penavin

Once you rule out the obvious you may need to consider malware as a possible cause. See also this related thread for further suggestions
