Rules

While we are not an official Mozilla community, we have adopted the Mozilla Community Participation Guidelines as far as it can be applied to a bin.

Rules

  1. Always be civil and respectful
    Don't be toxic, hostile, or a troll, especially towards Mozilla employees. This includes gratuitous use of profanity.

  2. Don't be a bigot
    No form of bigotry will be tolerated.

  3. Don't post security compromising suggestions
    If you do, include an obvious and clear warning.

  4. Don't post conspiracy theories
    Especially ones about nefarious intentions or funding. If you're concerned: Ask. Please don’t fuel conspiracy thinking here. Don’t try to spread FUD, especially against reliable privacy-enhancing software. Extraordinary claims require extraordinary evidence. Show credible sources.

  5. Don't accuse others of shilling
    Send honest concerns to the moderators and/or admins, and we will investigate.

  6. Do not remove your help posts after they receive replies
    Half the point of asking questions in a public sub is so that everyone can benefit from the answers—which is impossible if you go deleting everything behind yourself once you've gotten yours.

Using Firefox on Windows 11 and it is taking 10GB of RAM. it's slow and hangs so I cant use it.
Firefox on Android is awesome: fast and responsive!
Why does it take so much RAM on Windows but works very well on Android with 2GB of RAM?

@[email protected] The amount of RAM Firefox consumes depends on several factors. It could be due to a misbehaving browser extension, a website issue (I remember Firefox eating a lot of memory when I stay on YouTube for too long, with that browser tab taking up around 8GB, and I only noticed it because my system warned me about low memory, even though I have 32GB of RAM), or the number of tabs you have open.

If you encounter this issue (when it uses 10GB of RAM), try opening a new tab and enter "about:memory" in the URL bar. Then click on "Show memory details" to get a comprehensive breakdown of each process and its RAM consumption. If you prefer a simpler view, you can use "about:processes" instead of "about:memory."
