This section is like dessert to me, I am lost and going to die.

So here is my question with example

Person A : Running FireFox 60 version on Win 7 64 bits

Person B : Running FireFox 60 version on Win 7 64 bits

Both are running same things, Question if user agent is going to be the same? or different?

if there is something else in computer or software which is going to make their user agent different?

I am not a technical guy and need to clear this up.
 
There tons of things to take in consideration such as the fingerprint, cookie profiles, timezone, browser language etc. You are not going to hide yourself behind a different user agent basically.

You know 10% of users in the internet use the same user agent because of the common of chrome and windows 10.
 
The UA string of Firefox itself is broken down into four components:

Mozilla/5.0 (platform; rv:geckoversion) Gecko/geckotrail Firefox/firefoxversion

  • Mozilla/5.0 is the general token that says the browser is Mozilla compatible, and is common to almost every browser today.
  • platform describes the native platform the browser is running on (e.g. Windows, Mac, Linux or Android), and whether or not it's a mobile phone. Firefox OS phones simply say "Mobile"; the web is the platform. Note that platform can consist of multiple "; "-separated tokens. See below for further details and examples.
  • rv:geckoversion indicates the release version of Gecko (such as "17.0"). In recent browsers, geckoversion is the same as firefoxversion.
  • Gecko/geckotrail indicates that the browser is based on Gecko.
  • On Desktop, geckotrail is the fixed string "20100101"
  • Firefox/firefoxversion indicates the browser is Firefox, and provides the version (such as "17.0").
  • from Firefox 10 on mobile, geckotrail is the same as firefoxversion.
The recommended way of sniffing for Gecko-based browsers (if you have to sniff for the browser engine instead of using feature detection) is by the presence of the "Gecko" and "rv:" strings, since some other browsers include a "like Gecko" token.
For other products based on Gecko, the string can take one of two forms, where the tokens have the same meaning except those noted below:

Mozilla/5.0 (platform; rv:geckoversion) Gecko/geckotrail appname/appversion
Mozilla/5.0 (platform; rv:geckoversion) Gecko/geckotrail Firefox/firefoxversion appname/appversion

  • appname/appversion indicates the application name and version. For instance, this could be "Camino/2.1.1", or "SeaMonkey/2.7.1".
  • Firefox/firefoxversion is an optional compatibility token that some Gecko-based browsers may choose to incorporate, to achieve maximum compatibility with websites that expect Firefox. firefoxversion will generally represent the equivalent Firefox release corresponding to the given Gecko version. Some Gecko-based browsers may not opt into using this token; for this reason, sniffers should be looking for Gecko — not Firefox! Whether this token appears is controlled by the "general.useragent.compatMode.firefox" boolean pref.

The answer is yes? Going to be the same.

@meannn bro I am simple man.
 
User agent is a simple header sent by a browser on a HTTP REQUEST. Easily modified and changed but if it's a standard out of the box consumer browser with no plugins/extensions, it will be exactly the same (if they are the same version of the browser).
 
In theory yes, but like posted above certain plugins will add stuff to your User-Agent but they are not that common.

Just don’t try to spoof your Firefox browser to be a Chrome browser because some sites can detect that you are lying.
 
But on the OP he specifically says that both are 64 bits

Exactly, in a 64 bit OS you can run both 32 and 64 bit binaries and Firefox does maintain 32 and 64 bit distributions which means you could have a 32 bit browser installed in a 64 bit OS and it wouldn't be too weird, especially since it took them quite a while to release the 64 bit version.

Ahhh... capito. Yeah you are totally right. Didn't think about that scenario lol.
 
Got it guys, I solved the puzzle.
