If you need to run 32-bit Firefox or manually install 64-bit Firefox, you can simply download and re-run the Windows (32-bit or 64-bit) Firefox installer from the Firefox platforms and languages download page. But Ive read in another post that the JRE just runs the bytecode and it doesnt matter if it was generated by a 32 or 64 bit compiler - it will run it correctly anyway. You can still manually install 64-bit Firefox, if you choose. 64bit the conclusion was that I should install the bit flavor of Eclipse corresponding to the JRE version I have on my machine. If you see “(32-bit)” and are running Firefox 56.0.1 or newer, then your computer may not meet the minimum memory requirement for 64-bit (3 GB RAM or more).If you see “(32-bit)” and you are running Firefox 56.0 or older, updating to the latest Firefox version should automatically upgrade you to 64-bit.
Check your Firefox version (in the “About Firefox” window) and look for “(32-bit)” or “(64-bit)” after the version number: I am an amateur Java programmer (Took 'Java 101') and up to now I have been coding basic private Java application programs using Eclipse 2.1 on Windows XP and am ready to download a new Eclipse editor. I just bought a new HP laptop with Windows 8. The utility has many different applications, which are based on Eclipse technology: an integrated environment for the development and use of IDE Eclipse Rich Client Platform RCP.
If you’re running 64-bit Windows ( here’s how to check), your Firefox may already be 64-bit. The Microsoft Answers community referred me to you. Linux and macOS users, fret not, you already enjoy a Firefox that’s optimized for 64-bit. Eclipse is probably best known as a Java IDE, but it is more: it is an IDE framework, a tools framework, an open source project, a community, an eco-system, and a foundation. Also, with the jump from 32 to 64 bits, a security feature called Address Space Layout Randomization (ASLR) works better to protect you from attackers. Here’s the key thing to know: 64-bit applications can access more memory and are less likely to crash than 32-bit applications.
What’s the difference between 32-bit and 64-bit? How much less? In our tests so far, 64-bit Firefox reduced crashes by 39% on machines with 4GB of RAM or more. That means you get a more secure version of Firefox, one that also crashes a whole lot less. Users on 64-bit Windows who download Firefox can get our 64-bit version by default.
