I use Chromium snap shots:http://commondatasto...index.html?path=Win/
I use the Win32 zip files, not the mini installer. Also I back up the current Chromium local data and executable folders before overwriting in case I need to back it off. The snap shots are surprisingly stable. Now and then I got that LastPass Yellow Flag. But updating to latest LastPass for Chrome along with trying snap shots until I didn't get the yellow flag seems to have done the trick.
For privacy in Chromium there's an "about:flags" option "Disable hyperlink auditing" that supposedly prevents the tracking ping from being sent. Also Chromium doesn't have the unique ID thing that Chrome does.
Chromium doesn't have as many extensions as FireFox but I find I don't need as many. Also some I install but only enable manually to use, then disable again, such as bookmark sorting, dead link removal etc..
I set Chromium to load with an empty page, then have my Speed-dial2 open when I hit the Home Button or New Tab. That way it loads quickly even if the HD is busy at launch.
I use FF as my secondary browser. Opera I use only occasionally. Anything IE based including MaxThon, I don't use at all. I have no need to run web based ActiveX Controls or BHOs.
The nice thing about trying Chromium from zip is if I get a buggy one I copy back my local user data and exe folder backups, and the bug is gone. If you dabble across major version numbers it's a good idea to keep a backup for each Chromium version so that you don't get an error about config from a newer version if you back off. But it doesn't take that much space. Now I only save v. 18.x and 19.x Chromium. I've been running the 18.x snap shots long enough to know I'm not going back to 17.x or earlier. A few hundred MB of backup is all I need.
