More reasons for switching to Firefox include the ability to easily set up a self-hosted sync server allowing you to share your browser settings across several clients. While Chrome for Android does not support extensions, the mobile Firefox version does allow you to install ad blockers while being able to sync your mobile and desktop clients. AFAIK, Chrome for Android does not support a custom sync server at all.

I recently switched from Chromium to Firefox and am running Firefox on my Linux system as a different user than my main account for increased security. The only thing that bothers me is the missing magnification bubble which is used by Chrome for Android if it cannot reliably determine which link I clicked on.

If Chrome allowed to block ads on mobile devices and implemented a feature for easily setting up custom sync servers, I would happily switch back for security reasons.
