I seem to have multiple installed copies of Firefox, is this OK?

I run Windows 7 Pro SP1 64 bit. Looking in the Control Panel, I find the following line items:

Mozilla Firefox 15.0 (x86 en-US) 8/28/2012 40.5 MB

Mozilla Firefox 15.0.1 (x86en-US) 9/7/2012 40.6 MB

Mozilla Maintenance Service 9/7/2012 327 KB

Mozilla Thunderbird 15.0.1 (x86 en-US)


Firefox seems to be working OK, and Help About shows version 15.0.1

Shouldn't the update process have automatically deleted the prior version? If I uninstall 15.0 in the control panel will it mess up Firefox? Thanks for any advice!

You only need one version of Firefox. It will be worth backing up your Firefox profile before doing any uninstalling. See Back up and restore information in Firefox profiles

I imagine you have done manual non standard installs, as Firefox normally updates and removes the previous version.
