I have a 'transaction browser' - all my internet shopping is done in this browser; online banking too; when I close the browser cookies/cache/offline site data are all cleared automatically; this browser is also given an extra layer of security by eset

I have a 'logon' browser for sites eg TG where I wish to remain logged on, but don't need the extra seurity

I have another browser for using when I think I have enough tabs open already in browser 2 but don't want to close any

I have a couple more in reserve in case some sites don't work in broswers 1/2/3 which are carefully set up - I can fiddle with a reserve browser on the fly but carefully, until it works [kind of guy I am]

I've noticed this point you make - for example there is a site I use regularly that offers a 10/20% discount every visit provided I revisit 'cookieless'; it's not the only one
