You don't need to trash anything. The only thing that gets replaced is the actual application, "TenFourFoxXXXX.app", when you put the new version into your Applications folder. Just download and unzip it, then move it to your Applications folder.
Thanks again Chris, I¹ve moved the existing application from the desktop
into the applications folder and I¹m assuming that when I download the
updated one, unzip and move the new application into the folder it will
automatically replace the existing one??
Update now complete after third download and giving the computer a rest! The
zip file came through fine, unzipped and the application is in the apps
folder and working well. Thanks and keep up the good work at TenFourFox,
Chris, sorry to bother you again, but when I¹ve downloaded I get this
And my computer tells me that it doesn¹t have an application to open this
As you saw previously, my last update was a proper zip file.
Be glad of any help with this one.
