Hi. I've seen 2 version of firefox is installed to my system (both are 64x). one of those are 59.0.2 and other 65.0.2. but i only installed one version that downloaded from mozilla web site. So is this normal ?

I'm running windows 10 version 1809 ( build 17763.379 )

/* if i try to uninstall older version, both version uninstalled! and i already try to fresh install of firefox and windows, but still have same problem*/

/* and also sorry for my bad English (: */

Did you verify that both version are accidentally installed (i.e. you have two Firefox installation folders).

Note that in some cases the updater doesn't remove a registry entry of an older Firefox version, but merely add a new entry leaving the older entry as a orphaned entry and uninstalling in such a cease removes the current Firefox release as well.

You can edit the Windows Registry or use a registry cleaner to remove this item.

Sometimes an old version gets left behind with a new install.

You can remove the older program but first, make sure v65 is listed as your default.

If something should go wrong, just get the full installer from; Download Firefox For All languages And Systems {web link}
