Firefox.exe is constantly taking more memory (windows XP). Why?
When my PC slows down I check the processes running, Firefox is taking more memory like an electric utility meter?

There has been a virus named firefox.exe It is basically a miner bot, that hogs your resources. While I am not certain about this, it definitely is a possibility, as Firefox usually has very little resource usage overall. You could try doing a thorough PC cleanup to confirm or deny suspicions on that front.
RKill to kill any malicious processes -> Check programs for recently installed ones that might be malicious -> Run a full scan with anti-virus software of your choice -> Scan with Malwarebytes, Hitman Pro, and AdwCleaner -> Use CCleaner to clean up registry and cached files -> Use Firefox cleanup tool -> Check if it works properly now. Let me know if this helps!
Hi !
Would you please take a look at the article :
Firefox uses too much memory (RAM) - How to fix
This could also be caused by Multi-process (e10s)
If you are using e10s, you could turn it off as follows :
Type in the address bar about:config (press Enter) (promise to be careful, if asked)
Type and search for the preferences :
browser.tabs.remote.autostart and set it's value to false (default)
browser.tabs.remote.autostart.2 and set it's value to false
Note: the exact name of the preference may vary, but it will start with browser.tabs.remote.autostart
