I've grown tired of the firefox/iceweasel memory hog for a couple of reasons:
- it is such a memory hog and this isn't a machine particularly short of RAM but I still notice it when compiling with a few FF windows open and FF is just generally slow.
- the upgrade behaviour of iceweasel is getting tedious, begging for a restart every time I do apt-get upgrade recently.
Chromium is just faster, everywhere. A nice touch is the new tab behaviour too - previews of the most recently viewed pages is far more useful than the usual homepage. Chromium is also faster than epiphany/webkit.
I'll still be using two different browsers, because neither iceweasel nor chromium can do the clever smart bookmarks thing of epiphany. I have come to utterly rely on bookmark input boxes for direct access to specific Debian bug numbers, individual PTS pages, Google searches, dwww searches, specific manpages, buildd reports and various other pages where a bookmark really needs to be an input box, not a label, and the bookmark itself sits on a toolbar and can then use http://url/%s which makes life so much easier.
Update
I wondered if epiphany smart bookmarks would be understood but
apparently not. So:

The smart bookmarks are BTS, Google, PTS, buildd and man. At work, I've got a wider screen and I add several more for internal bug tracker numbers and similar.
Chromium and iceweasel/FF have nothing like this. Entering a bug number is utterly trivial - it even works with middle mouse button paste which, cleverly, opens the page in a new tab too. Iceweasel/FF can do this ONCE but only once, via an extension. The key points with epiphany are:
- It is trivial to setup - just make a bookmark with a %s and put that bookmark onto a toolbar - any toolbar.
- it is trivial to use and never needs any use of the address bar or editing anything
- It works for any query which can have a single argument at any point in the URL.
- You can have as many as you want, subject to how many toolbars you can use
So, yes, Leo, the way epiphany does this is
massively more effective for a "work-type" browser situation where there is such a need to access a specific page immediately, with no editing or keyboard usage.
