First of all, I am a newbie on this forum and in mac world so forgive me if I'm doing something wrong 
I bought my first MacBook three weeks ago and was using Firefox for the first two but then I decided to switch to Safari. I love it but I have a couple of questions/problems. I did google it but found mixed responses.
1) Safari sometimes doesn't save passwords, even does't ask me if I'd like to.
2) this:
It shows every time I launch Safari. I'm deleted Saft (used AppTrap) but looks like there are sill some files left. And I have no idea what to do with this SIMBL thing... Sorry for being such a noob!
Your help would be really appreciated!
