What version of Firefox do you have?
There are several ways to find out which version of Firefox is installed on your system.
Method 1: Programs and Features applet
You need to go to the panel Windows controls, the "Programs" section and find Mozilla Firefox in the list of installed applications. To do this, click the "Start" button, then in the right half, click on the link "Control Panel".
In the new window we find "Programs" -\u003e "Uninstall programs".
This will take you to the Programs and Features applet. Find Mozilla Firefox in the list of installed programs.
Bit depth will be indicated next to the name in brackets installed program– (х86 ru) or (х64 ru). Here you can get a little confused, because if everything is clear with x64, then what x86 is, some users may not know. Although this topic is worthy of an entire article, now we will not talk about it, but simply explain that x86 is the 32-bit version of the browser.
Method 2: "Task Manager"
Launch the Firefox browser if it is not already running. Now, by simultaneously pressing the Ctrl + Alt + Del buttons, call the Task Manager, where in the “Processes” tab you can see which version you have installed:

Which version of Firefox is the best?
This topic is fully covered in the article ": Comparing performance and memory consumption in browsers", which you can read on our website. For those who don't have time to study such a long text, let's copy the conclusion we reached in that article:
In Firefox and browsers based on it (such as Pale Moon) it would be wiser to stay on 32-bit for the time being, as switching to 64-bit results in significantly more aggressive RAM consumption without bringing a significant performance improvement.
How to upgrade to 64-bit Firefox?
The good news is that upgrading Firefox from 32-bit to 64-bit is very easy. All that is usually required is to download the special 64-bit installer from the official Mozilla website and run it.
At the time of this writing, for Windows x86 a network installer is offered (i.e., when it starts, it will download the Firefox distribution from the network), and for x64 it is a classic installer that already contains the program itself and does not require an Internet connection.
All your shortcuts, profiles, bookmarks, extensions, and so on will continue to work in Firefox of a different bitness.
Note: The 32-bit version is not automatically uninstalled. We suggest that you do not delete the 32-bit version while you are testing the 64-bit edition of the program. And after you decide which browser assembly you will work with, remove the unnecessary one.
However, before downloading a 64-bit copy of Mozilla Firefox, you should make sure that the operating system can work with it. Let us remind you once again: the 32-bit edition of the browser will work on both Win x86 and Win x64, but the 64 version only supports Win x64.
In order to find out the digit operating system, open the "Start" menu, on the right side, find "Computer". In the window that appears, click on the "System Properties" button:
