I downloaded Firefox version 43.0.4, 64-bit from their official site and installed it. Before this, I had the Firefox 32-bit version. My OS is Windows 10, 64-bit.
I did not remove the 32-bit old version, just installed a fresh new 64-bit. When I run the browser, I don't see information anywhere confirming that I'm running the 64-bit version.
Can you tell me where I can find information about the bit version of the browser that is being run?
