Hi,
After discussion with Pascal Bellard (bellard), i enable https for all websites (main site, forum, ...).
Before enable this, i have checked is ok for SliTaz 3.0, 4.0 to avoid miss user experience.
With SliTaz 3.0 and firefox package (3.5) is ok.
With SliTaz 4.0 and firefox package (10) is ok.
Sorry for midori user but not work with him, i check to find solution :'(.
With SliTaz 5.0 work with Midori / Firefox
