Yesterday, I try the newest software from Google, which according to him can improve speed access our internet, especially to friends, which is surfing from Internet Café (Warnet). This Software called by Google Web accelerator.
After I download it (the size about 1,65 MB), I try using it on firefox mozilla. In the reality, its inappropriate expectation result.
At first, I try to open "http://aku.punya.web.id", after some my second await; in the reality, error page is happen. I try once again, error, error page. Because sulking, I set mind on to close Google web accelerator. Then, I try to open "http://aku.punya.web.id" again without it, finally walk at ease.
