should I uninstall FF34.0.5 if I want to install FF37

I have Windows 7 Pro 64 bit x 64. and I want to install the new FireFox 37.0a1. I don't know if I need to uninstall the old Firefox 34.0.5 before installing the FF37? How the sill, this affects things I have on the old program and should I do it or not? I had many problems with the old program.

nocturnal compilations of 64-bit for Windows are generated only for test compilation errors and are not all tests that get to other builds, so the risk that something is wrong can be very high.
Also, the Nightly build is updated daily unlike the Release version that receive an update every six weeks.
If you are not experienced in dealing with issues, then you should stay with the Release version.

  • Should I uninstall PC Cleaner Pro?

    I have a problem with Windows Media Player.  I did a search for 'Windows Media Player Fix'.  I clicked on a site which had the logo of Microsoft in the address bar and click on "fix now", and PC Cleaner Pro was downloanded.  When I click "Run", he did a scan and said that my computer has more than 3,000 problem that had to be fixed.  When I click 'fix now', I asks me to register.  After that, I'm suddenlys asked not to purchase the product at a special price of $29.95 - there is no mention of the cost prior to this point.

    Have I been scammed, and my pc is today under threat?  I did not buy a product - I thought I was getting a fix from Microsoft for my computer.  I closed the window - should I uninstall PC Cleaner Pro?  It is now listed under all programs - but since I didn't buy it, I'm leering to try to use it.

    In addition, what is PMB Launcher?  Some how its icon and help to PMB, poppped up on top of my computer - I didn't knowingly download it.

    Thank you.

    Of course, you should be concerned.  No matter what program that does no benefit apparent but gets itself installed and then taking measures either make it difficult to uninstall it should be presumed guilty until proven innocent.  There are lots of lucrative things, mean that a program can do to your PC once you have given the OK to install.  Programs running all the time and have been installed with privileges you - that's why Windows will ask you if you allow installation - can do things like snoop your files or watch as you type a password.  The fact that he tries to avoid uninstalling there as evidence that its creators see some advantages to keep on your machine and makes him suspicious.

    If you want to install a product cleaning or antivirus, so don't forget the company, you buy some.  Unfortunately, bad companies have become very smart in the game system - creating several websites, supposed to give rave reviews, fake users on legitimate review sites, etc.  I really have no idea how say you who you can trust.  For this company, I have no way of knowing trust them or not.  But your question, bad things can happen in a program just to be on your computer - absolutely.  Do not install foreigners.

    It is not necessary to uninstall your current version first. In fact, it would probably be a good idea to leave it installed until you are certain you have everything works the way that you want with the new facility. When you install Lightroom CC 2015 it will prompt you to allow him to create a new copy of your catalog. You should allow this to happen. Then the new Lightroom should pick up right where you left it. Once you are sure that everything has been installed correctly and you no longer need the old version you can then uninstall it. Both versions are completely independent.
