if someone wants to reinstall the latest version he have to delete it first.
it would be much better if we just could download it again and overwrite the installation.
thats for chrome and firefox.
otherwise i would like to inform you, that if im donwloading chrome version i have to drop the installation file into chrome. (no "add to chrome" or "install" button showed, just donwloaded to download folder. i get a lot of reports from users who have the same trouble)
1. No i don't remove this feature. Most users want to see if they have the newest version.
2. You really should read the messages bellow the download button...
