GU are really working hard and now we can excepts one click gifts on chrome and it really accepts the super fast so give them time and im sure they will be able to use chrome for the snag bar in the future and stop moaning just play on chrome and snag on FF

Firefox frequently becomes unstable when it comes to Farmville these days. There are a lot of delays, hang time, out of sync, and bits lost. Today was the worst it's been in some time, so I came over to Chrome. Imagine my disappointment to find that you don't support anything for Chrome. Oh, I see you're working on it ... same line we always get from Zynga.

They need to get it for Google Chrome then the snagbar will get popular :) Because i honestly don't like using internet explorer i don't know about you guys i prefer google chrome :L

From the install page FAQ

"What browsers do you support?
We support Firefox and Internet Explorer but do not support their beta future releases. (Firefox 4.0 and Internet Explorer 9 at the moment) We are looking into supporting Chrome but don't know when it will be ready yet.
"

I can't wait for the Chrome version!

I also found that Google Chrome cannot install the Snag Bar feature. In a fashion this makes GU advertising them a bit fruitless, unless they are going to remedy this. I used Chrome until GU came out and this was the first thing I discovered. So I was forced to switch to Firefox.

or ie as well

no it doesn't work yet on google chrome, i have to use it only on firefox :)
