Firefox no longer works with some versions of Windows XP

This article only applies to Firefox on Windows.

Firefox support is ending for Windows XP and Vista. See this article for details.

Windows XP with Service Pack 2 is the minimum Windows version that meets the Firefox System Requirements. We'll explain how to find out your Windows XP version and what to do if you're using Service Pack 1 or below.

Note: In all cases, it's best to upgrade to the latest version of Windows, if you are able to. Microsoft no longer provides security patches for Windows XP.

How to check which Windows XP Service Pack is installed on your computer

  1. Click on the Windows Start button and open the Control Panel.
  2. Click on the Performance and Maintenance link (Category View only), then click on System to open the System Properties window.
  3. In the System Properties window, select the General tab. Within the information in the General tab, it will tell you which service pack is installed (if one is installed).
WinXP-SP3

Service Pack 2 or 3

If it says Service Pack 2 or Service Pack 3, your Windows system meets the requirements for the latest version of Firefox.

Service Pack 1 or nothing at all

If it says Service Pack 1 or nothing at all, your system doesn't meet the Firefox system requirements. The only popular web browser that is still being updated with security patches for older versions of Windows XP is Opera.

To download and install Opera, visit the Opera website.

Note: Opera 36 is the last supported version for Windows XP. According to the Opera May 4, 2016 release notes, As of Opera 37, the minimal system requirement for Windows users is Windows 7. Windows XP and Vista will no longer receive feature updates, only security and stability updates.

Bug 1233779 - Don't serve Firefox 43.0.2 and higher to XP SP2 users A note since Firefox 43.0.2 is out, in case anybody encounters WinXP users having trouble downloading or installing 43.0.2 if they have SP2 and not SP3. May need to update the https://support.mozilla.org/en-US/kb/firefox-no-longer-works-some-versions-windows-xp article.

Hi,

Sorry for the late heads up. :( In bug 1079858 [*] we are going to switch to SHA2 signed installers, which do not work in XP SP2 (they won't launch silently).

As a work around we need to serve Firefox 43.0.1 to XP SP2 users. With 43.0.1 installed they will be able to upgrade to 43.0.2+ without any major issues.

Thanks! I posted a background/related discussion thread in that article's kbforum,

https://support.mozilla.org/en-US/kb/how-can-i-get-latest-version-firefox-windows-xp/discuss/6442

That article was renamed How can I get the latest version of Firefox on Windows XP or Vista? so the discussion thread is now at https://support.mozilla.org/en-US/kb/get-latest-version-firefox-windows-xp-vista/discuss/6442

I'll remove the "Needs change" entry to review this article.

From Opera 37, xp is not supported any more.

...As of Opera 37, the minimal system requirement for Windows users is Windows 7. Windows XP and Vista will no longer receive feature updates, only security and stability updates.

if you like to download opera on xp then you served the 36.x version (Opera 36.0.2130.65) and not the latest (38.0.2220.31).

http://www.opera.com/download/guide/?os=windows&list=all

i don't know if we have to mention or to remove permanently this step (the option 2 i mean)

thoughts ?

As long as Opera 36 is still available and since Windows XP and Vista will no longer receive feature updates, only security and stability updates. I think we should keep Step 2 but maybe add a note similar to this?

{note} Note: Opera 36 is the last supported version for Windows XP. According to Opera's May 4, 2016 release notes, As of Opera 37, the minimal system requirement for Windows users is Windows 7. Windows XP and Vista will no longer receive feature updates, only security and stability updates.{/note}.

I set up a "Needs change" entry for review.

With Opera no longer being an option, I was in the midst of removing it, and rewriting the article to explain how to determine which service pack you are running and how to upgrade to SP3. I found that the Microsoft article we link to doesn't seem to exist anymore. I found https://support.microsoft.com/kb/950717 but it doesn't explain how to upgrade.

Should we just provide the steps ourselves? I think it's available via Windows Update, isn't it?

I found https://support.microsoft.com/en-us/kb/936929 which includes this section:


How to obtain Windows XP SP3 For more information about how to obtain Windows XP Service Pack 3, click the following article number to view the article in the Microsoft Knowledge Base: 322389 How to obtain the latest Windows XP service pack


However, the 322389 link no longer works. I found http://www.zdnet.com/article/xp-sp3-download-it-while-you-still-can/ dated March 14, 2014, which says this:

There is some good news. While Microsoft refuses to issue any more updates for XP after April 8 -- <snip> -- Microsoft will still let you run Windows Update on XP systems after the April 8 date.

We should at least tell users how to check to see what Service Pack is installed. We can link to http://windows.microsoft.com/en-us/windows/which-operating-system ... or just use the information it contains in the section for Windows XP (Click the Start button, click Run, type winver, and then press Enter). If they don't have SP3 we should simply tell them to use Windows Update.

SP3 may no longer be available via Windows Update. See https://www.winhelp.us/install-service-pack-3-in-windows-xp.html Install Service Pack 3 in Windows XP Last modified: 2016-06-14


You cannot apply it via Windows Update / Microsoft Update anymore because this requires SP3 to be installed already.

Full download (aka Network Installation Package) of Service Pack 3 for Windows XP has been removed from Microsoft Download Center, but you can get the file from MajorGeeks. Make sure you try one of the Download@MajorGeeks links. Please save the file instead of running it.


The article then goes into detail about the installation process.

Oops. I didn't see any mention on the Opera that it would be maintained for XP users. Thanks.

...but you can get the file from MajorGeeks...

I have trust issues with MajorGeeks. They offer Firefox builds and advertise them as final releases before Mozilla is finished release testing. I would rather tell users to pay for a Windows update or tell them they're out of luck, than point them to a third-party website to get an old release. I don't think that linking to third-party sites for old Firefox releases is even allowed in the forum, so I don't think we should do that with Microsoft releases in the KB.

I didn't mean that we should link to MajorGeeks. I was quoting from an article reporting that SP3 is no longer available via Windows Update and that Microsoft no longer offers it for direct download. In any case, we should at least tell users how to check to see what Service Pack is installed and we should should remove the nonworking Microsoft link.

More information (from my post in this other thread).

I updated the thread title since we aren't going to remove Option 2 but we may want to add a note.

Hi Alice, your Note seems great for the article.

I made some edits that need review.

So instead of removing the Opera section, it looks like we should remove the SP3 section. LOL

And the article would be something like:

  • check which SP you have
    • If it's SP2 or SP3, this article doesn't cover your problem. Link to better article.
  • If it's SP1, use Opera.

No feedback regarding the above?

I never got an email notice about your earlier post.

The outline for a new revision sounds OK.

And I never got an email about your post. LOL I'll have a draft up soon.

I've submitted a draft. I assumed that SP1 users visiting opera.com will be offered the correct version, but I can't test that.

You didn't mention the original version of Windows XP.

Do you know what the System Properties window says on the original version?

Here's an image I found showing Windows XP with no Service Pack, from http://www.emulators.com/xptutor.htm

Okay, I've tried to account for original XP users. Keyword: tried. :) This article makes me wish support for Windows XP was dropped entirely.

You and me to...XP should be declared dead withe the SHA-1 change as the excuse.

I hope you have cross linked with https://support.mozilla.org/en-US/kb/get-latest-version-firefox-windows-xp-vista/discuss/6442

Looks like this article and that are very tightly related.

The helpfulness score has taken a dive, so I approved my edit.

Yup. It's linked from the "Does it say Service Pack 2?" section.

This note was removed from the article in a later revision:

{note} Note: Opera 36 is the last supported version for Windows XP. According to Opera's May 4, 2016 release notes, As of Opera 37, the minimal system requirement for Windows users is Windows 7. Windows XP and Vista will no longer receive feature updates, only security and stability updates.{/note}

I think we should add it back.

P.S. In case the Opera website doesn't automatically offer version 36 to WinXP users we could either linkify Opera 36 in the above note (Opera 36.0.2130.65 for Windows) or we could link to http://www.opera.com/download/guide/?os=windows&list=all (all Windows versions are listed).

Never mind! The Opera download site will detect your OS version and will serve you Opera 36 according to http://www.opera.com/blogs/desktop/2016/04/opera-stable-36-0-2130-65-update/

Dave-H RafaellaG • 3 months ago No, that's 36 as well. I guess the fact that I'm using XP is being detected and it's serving me the last version for that OS, which is fair enough. I assume Vista users are getting the same.

See https://support.mozilla.org/kb/your-hardware-no-longer-supported/discuss for the background.

Windows XP/Vista support is being phased out slowly, by transitioning users to Firefox 52esr. I set up a "needs change" entry for March 2017 to review the status and needed updates. See:

https://support.mozilla.org/en-US/forums/contributors/712204 End-Of-Life plans for Windows XP/Vista systems? Posted today by philipp:

According to https://bugzilla.mozilla.org/show_bug.cgi?id=1305453 the future of Firefox on XP and Vista systems just got a bit clearer: Users on those systems will be transitioned to the Firefox ESR branch in March 2017 where they'd still receive security updates but no more new features until 2018. Newer Firefox versions (53 & up) would no longer install on those systems. I guess it's rather safe to assume that after the 52 ESR cycle, XP and Vista are likely becoming unsupported by Mozilla.

Bug 1305453 - Prevent non-esr stand alone installers from installing on XP/Vista (Fx53 and up)


im Mathies [:jimm] 2016-09-26 09:01:09 PDT

We plan to eol XP/Vista by first moving those users out to ESR 52. Once 52 merges to aurora, we should land changes to the stand alone installer to prevent install by XP and Vista users. Initially there shouldn't be an issue with running but eventually we'll import a system dependency that will break browser startup.

Masatoshi Kimura [:emk] 2016-11-08 18:31:00 PST

Title: stop generating them for Firefox 53 Comment #1: We should also generating SHA1-signed installer starting with Firefox 53.

Which is correct? Note: If we don't generate sha-1 installers, Firefox 53+ installers will silently fail to start on XP/Vista. So bug 1305453 will be moot.
