I love the Firefox browser -- in theory. It's free and open-source. It's got tons of extensions . . . and that's part of the problem. My former favorite browser is a terrible memory hog, at least on the (ahem) low-end machines that I can't get enough of.
Better to use the browser developed for, and integrated with, the GNOME desktop, one of the main options on Linux desktop computers, and the default desktop for vanilla Ubuntu Linux. (New version tomorrow!) Thus the theologically-appealingly-named Epiphany browser. Its speedy because it doesn't try to be all things. There are a modest set of extensions, which I added. More about that in a moment.
I had one complaint. When I Control-T'd to create new tabs, the cursor didn't start in the address bar, so I would have to mouse to it to add an address. The solution is simple, if you know that the term term for starting in the documentation is focusing.
Set you start page as "blank" by going to Edit > Preferences > General tab > Home page > "Set to blank page." It'll work now.
But what I really love is the extension that synchs my bookmarks with my del.icio.us account, both from home and work. This allows easier tagging of sites I like and lets me search for saved sites by keyword in the address bar, rather than trying or looking for the URL. I can tell my Google searching has dropped already. (Then again, I have almost 2300 links recorded.)
The downside is that some sites break badly in Epiphany -- it has a tiny market share -- so I keep Firefox in reserve.
