My shocking moment

Yesterday night at about 11pm, i opened my e-mail and checked any comment on my blogs. I was very happy because there was a comment and i published it. After that i went to view my blog page. To my surprise, i saw all my goggle advertisement disappeared, it made me shocked.
Few thoughts over my head, what went wrong?
1. Did i do something wrong?
2. Did goggle disable all my advertisement?
3. Did hacker come in to disable it?
Few minutes later, i went to lay out page and found that it was disabled too, i saw some features like save button, add a new page, no long exist.
I knew that i never broke the goggle rule and was wondering what actually happened. I tried to view my blog again but only saw my blogs but no advertisements.
Ten minutes later, i look the computer screen carefully, I found a small icon "No script version 1.2", suddenly I realized that" adds on" might be installed by my workmate Mr. Desmond. He always like to install all kinds of Software like anti-virus Software ,Internet security Software, Internet speed Software. I then enabled " Allow ScriptsGlobally ", this time i could see all goggle advestizementon my blog pages again, i felt really relieved.
This morning, Mr. Desmond phones me:
He says : sorry i forgot to tell youyestaerday that i had installed the lastest version Mozala Firefox 3Beta2 with adds on function to block Javasript, etc.
This was my shocking moment for yesterday. I wish all of you happy new year2008.
