At this time, I found 3 bugs that were present before but I have not described them.
1. We all know that the console webbrowser is something like mozilla, and mozzila has a commands, like "about:config" (write this line in your PC firefox or mozilla about:config instead of the web address and it will open mozilla setup) but if you type it in the ps3 browser, console freezes but continues to work. And when you try to shutdown ps3 it sends data to the internet. For lack of time, i did not investigate that traffic and if you have a free time you can try.
2. Playstation 3 Earth - when watching description of areas there is a link to google, go for it, do a search, trying to move to another page and the console freezes.
3. Visual bug i will post video here soon.
And all bugs are working at 2.6 firmware.
