Three cross-platform tools to keep your web browser in sync
Fortunately, there are some simple (and free) tools available to minimize the hassle.
Opera doesn't get a lot of love on most software blogs, but it has some excellent features. Opera Link, for example, securely stores your bookmarks and other settings. Since Link support is built in to the browser, it's available anywhere you can run Opera - Windows, Linux, Mac, and even in Opera Mini.
Weave is still somewhat experimental, but one day it may be baked right in to Firefox. Since it's an add-on, Weave will work on any operating system. You can use it now as long as you're running at least version 3.5 of the browser and keep your profile marching in step - even on the Fennec Alpha.
Another great way to tackle this chore is with a cross-platform file sync application like SpiderOak - which runs on Windows, Mac, and Linux. The 2GB of storage you get with a free account is more than enough to keep Chromium, Firefox, and Opera in sync. It's a bit of work to set up, but once you're done SpiderOak will keep things up-to-date in the background on all your systems and OSes.
