Build Identifier: 

Offering Firefox 4 to OSX 10.4 users would just annoy them, see

Reproducible: Always

Steps to Reproduce:
1. Go to
2. Download Firefox 4.0.dmg
3. Try to install
Actual Results:  
The installer doesn't work.

Expected Results: does a bit of user agent sniffing and doesn't offer Firefox 4 to systems with not supported operating systems.
yeah, let's avoid this. easy fix?
Ever confirmed: true
Adding it to the release queue - thanks!
Target Milestone: --- → 2.0
The bug headline mentions only 10.4 but the scope must be widened: All Mac OS < 10.5 and all systems with PPC must not be offered to upgrade to Fx4.
Changed the name of the bug per comment #3 (good catch). Steven/James/Anthony - this feels important enough to do as a one-off once we get through the mobile release if at all possible. Definitely bad form to be serving up a version to these people that they can't actually use.

My recommended fix:
- display 3.6 button with a small note that reads "Unfortunately Firefox 4 is not compatible with your computer's operating system. _Learn more_."

Note that these new strings will require localization for all of our locales.

Also, this week end I changed the behaviour of all our localized whatsnew pages shown to our 3.0.x users to show 4.0 as a recommended upgrade if they are on windows/linux and 3.6 if they are one mac so as that we make sure we don't loose existing long term users by proposing a 4.0 version that doesn't work for them (those that do a 3.0 -> 3.6 can be upgraded selectively later with the Major Update upgrade process). It may be good to do the same for en-US.

This needs to be the highest priority thing for IMO. No strings needed, just remove the download button, or redirect to all-older.html.
Dupe of bug 644255?

Not exactly, that bug is dealing specifically with the promos on the 3.6 whatsnew pages. Lets keep them separate as the technical fix is very different.

Anthony is going to work on this, but it's not a quick fix because of the various download buttons across the site. I'll see if I can help him out at all.
Thanks James and Anthony - really appreciate it. If this is complex enough that it needs to be done in stages, I'd start with the homepage. Fixing there asap will probably cover a lot of the problem and buy us a little time to resolve the rest of it.
done for locales in r86861 on production for, same thing on in r86864

Ideally we would have this fix in product-details so as to propagate it to all sites easily and I guess Thunderbird will eventually have the same problem, so it's more of a temporary emergency fix (especially since I would prefer us to clean up product-details than to add even more stuff in it :) )
Committed r86874 for a quick fix on the en-US home page.
Is there any kind of message displayed to the user?

> Is there any kind of message displayed to the user?

I think we need something explaining what's going on (see comment #4).
New strings mean localization, I intend to put the string in English for now as a short term fix though.

I would prefer a version-free message that we could reuse in the future, the one in comment 4 will become obsolete as soon as Firefox 5 is released.
Pascal, how about this?

Unfortunately the latest version of Firefox isn't compatible with your computer's operating system. _Learn more_."
it's a fine message, I wil use it in English for now and will put it on our localizers' plate, thanks :)

Raymond: We need to verify if this regressed. Here is a comment that we received:

"I just did some testing with a PPC Mac running 10.5.8 (I don't have 10.4):
When I used Safari, all of the Mozilla download buttons let me download 15.0.1 which will not run on that machine.
When I used Fx 3.6.28 I was taken to which tells me to update and let's me download 15.0.1. All Mozilla download buttons let me download 15.0.1."

We can check this out after the stub installer work.

I just tested this on a PPC mac. We have indeed regressed this sitewide. The notification we used to display is also no longer there.

Bless you for filing a new bug instead of keeping this one re-opened. Marking as VERIFIED since this was initially fixed (and verified) long ago.
