When using Firefox Panorama (in day to day use, I still call it tab candy), I find the zooming in and out to be rather annoying as it looks a bit choppy on my laptop. However, a quick trip to the configuration settings solves this quickly.
Open a new tab and go to location
Now go to the key
browser.panorama.animate_zoom and double click it to change
false. No need for restarting or anything similar, the change
immediately takes effect. Enjoy the quicker experience!
