As for myself:
On Windows 7 (64 bit)
Firefox (tried every new version this past year)
CPU Intel I7
Ram 8 gb
Pixl.us is extremely slow when I try to open its web-page.
I have bookmarked the pixl.us forum web-page (discuss.pixls.us
) and It always takes a lot for Firefox to open it.
Actually, no other web-page is so slow to load for me with my computer…
