Firefox has had a major UI change in version 4. The menu bar has been condensed down to a single button, tabs have been moved to the top rather than below the search and navigation bars. On the windows version, the menu button is located on top of the tabs which may result in an accidental button press if you’re not paying attention. It’s almost undeniable that Firefox borrowed this UI concept from Google Chrome.
One area where the differences between the two browsers is more apparent is sync. In Google Chrome, synchronization of your bookmarks and settings from one system to another is accomplished by logging in to Google. That’s it, no key codes or pass phrases to remember. Further than that, synchronization is practically instantaneous between systems running Google Chrome. Firefox’s sync gives you a few extra hoops to jump through, and key codes to remember. Sometimes, you just want to sync everything up when you’re not next to the primary machine.
Google is constantly updating Chrome, and bugs are being fixed almost as quickly as they are discovered. Chrome was the first browser to receive a fix for the WebKit exploit discovered in this year’s Pwn2Own contest. In this contest, multinational teams compete to see who can hack their way through various systems and software in the least amount of time. This exploit was not used against Chrome specifically, so there’s no telling whether or not it had a high potential of actually working. To Firefox’s credit, they survived the contest where they hadn’t in years prior.
As with any constantly-evolving software, everything mentioned here can and will likely change. Firefox has made huge strides in their efforts to reinvent the platform, and it may be just a matter of time before they come up with that new feature that blows Chrome out of the water.
