You may want to know that Ad block Plus and ad block has a business deal with Google so they show their ads from time to time... (yeah Google is that evil). The alternative is Ad Block Edge One thing I could never support with Chrome: The most visited page startup screen.
You cannot use a fixed startpage in Chrome (disabled, or most visited, that's all you have)
It's a "devil" feature: it force you to keep your bad habit running. I prefer having a startpage with stuff I dont do every day, but should do everyday. With a bit of config:about messing in Firefox you can have the startpage of your dream... and you can configure anything in firefox.
Opera "was" not that bad. The version 12 is awesome, and they invented almost every good feature every other browser copied. They changed past version 12 to accommodate for their success in smartphone browser share.. It's a chromium spin off, It's shitty now. They went from the more innovative browser, to the worst copy cat... Yeah smartphone ruin everything.
