I was running Firefox 3.6 with the following: BarTab Firefox Sync (Now integrated into Firefox 4; no longer needed as a separate addon) GreaseMonkey HTTPS Everywhere (EFF's addon based on NoScript design that forces HTTPS for listed sites; easy to add your own rules) NoScript TabKit (tabs on the left side, grouped based on how they're opened, indented as well; and color-coded by group) Did some testing with Firefox 4 (on one machine), discovered a few problems. BarTab half-works (it will still NOT load un-targeted tabs at launch time; but you have to manually reload any 'unloaded' page to get it to work; no other noticable issues - I don't auto-unload stuff after timer though) TabKit's Developer has been AWOL since October; so I had to move over to Tree Style Tabs - which emulates TabKit with the exception of the colored groups. I run Chrome for a few things (namely a few Google-centric things) but avoid running it for two reasons: They DO track the history of EVERYTHING in there - and their now-non-support for the "Do Not Track" feature that Google is now (AFAIK) the sole browser maker to say they're not implementing it. (Firefox 4 and IE9 have it, Apple's announced Safari will in the next major release; don't know yet about Opera though.) https://secure.wikimedia.org/wikipedia/en/wiki/Do_not_track_header http://donottrack.us/ That, and I've used Firefox for a long time - it'd be a massive pain to switch. I'm still using the official Firefox Sync servers for now; I eventually plan to set my own up at some point. Another useful thing is the 'Addon Collections' you can create. (Requires an account on the addons.mozilla.org site) You can pre-build a set of addons to install at once as a bundle. Be it for your own use, or just a pre-set list for users you support. I'll be creating two, one for me and a 'lite' version for family and friends (They would get frustrated at NoScript, for example) Keith Bachman
