Webpages started to load slow suddenly and this behavior has been so for over a week now. I usually use Firefox, with the following addons enabled: Adblock, Better Privacy, Flashblock, HTTPS everywhere, NOScript, and many others disabled. These extensions didn't make me problems in the past. However now it takes up to 16 seconds to completely load Google start page (ie. google.pt) or a search term (even in safary took 6 seconds to display searching for "weather new york"). It took 12 seconds to load forums.macrumors.com, and it takes about 6 seconds to load a simple webpage, measured with "lori" addon. ; Even if I use Safari or a different User, I still get slow page load. I'll have to use a different laptop with a different operating system to check if the time is still slow. I wonder if a small internet service provider is spying on my traffic ? I can not explain why it works so slow, could it be my Macbook ? I only remember I've done a Repair Disk Permissions recently and also installed Little-Snitch which I now removed. I dont use a router at home. I've just done a speedtest and it tested an internet speed of 75Mbps, it usually is 90Mbps, but right now I can see 80 customers in the network connected to the same ISP.
