After installing a patch for Firefox, there are two versions of it installed in a machine
说明
After executing a patch schedule to update Firefox, two versions of the installed software are listed, the original version before applying the patch and a new, separate version after installing it with a patch schedule
原因
This is related to the install path, in some cases Firefox has the name "Mozilla Firefox 84.0.2 (x64 en-US)" which is supposed to installed at "C:\Program Files\" directory (where all 64 bit applications should be installed by default) but it turns out that it is actually installed in the "C:\Program Files (x86)\" directory. When the patch schedule runs, it installs the update provided by Mozilla which might create a separate instance of Firefox instead of updating the current installation.
解决办法
To solve this situation, the old installation of Firefox needs to be removed and a new one must be installed making sure that it is at the correct location (C:\Program Files\ directory)
