I use Google chrome with multiple profiles to test web sites (each profile has it's own cookies etc). All works fine, but on Windows 8 google will create a new taskbar icon for each profile, and 10+ chrome icons on taskbar effectively kills it :(. Since profiles are switched using profiles top-left menu and additional icond are useless and meaningless - is it some way to limit chrome to just ONE icon for all profiles? Or somehow stack all icons into one icon using windows 7/8 "stacking" mechanism that google uses for multiple icons of one profile?
Several types of solutions:
A. Chrome workarounds (doubtful)
There is a very long thread Multiple icon Google Chrome in taskbar when use profil in which the problem of Chrome is analyzed as follows :
The above thread offers several workarounds that you can try, although they seem to work for some people but not for others. (Better keep a backup of any folder or file that you are advised to delete.)
B. Forced runtime grouping
The thread Win 7 task bar buttons - combine for some applications or not other applications offers another solution for grouping some currently running processes into one group. I tested it and it works, but the disadvantage here is that you will need to repeat the procedure every time.
The application used is 7+ Taskbar Tweaker, which seems to have been abandoned but is still available from CNET (use the button "Direct Download Link").
