No Legacy 4.0.x Updates

It should be noted that with the new 5.0 release and Mozilla's new rapid release cycle, the 4.0 release is not being treated as a legacy release as 3.6.x was. Users are being automatically updated to 5.0 (no "Do you want to upgrade to 4.0?" as with 3.6.x) and I don't think the 4.0 branch will be maintained now that 5.0 is out. This is much as Chrome updates are handled.

Sometimes, the impossible can become possible, if you're awesome!

Link to FF 4.0.1

I found this link that seems to still work to download the full Firefox 4.0.1 setup file:

ftp://ftp.mozilla.org/pub/firefox/releases/latest-4.0/win32/en-US/

I have to use 3.6.x since my online bank does not like 5.0 and directs be to install 3 or 4 of Firefox.

Could someone download the 4.0.1 file and recreate the portable apps version of FF4?

Thanks

Don't Use It

Firefox 4 should no longer be used for production use. Firefox 5 is the security and functionality update for Firefox 4. You can fake the version number to a specific website using an extension for websites that have no idea what they are doing (like your bank), there are a few available.

Legacy 3.6.18?

Will 3.6.18 paf appear?

I hope so. I still have not

I hope so. I still have not migrated my data to Fx 4.

Building Now

It's building now and will be out today. I highly recommend switching to 4.0 (now 5.0), though as 3.6.x will only be maintained for 'a short time', not the 6 months that Mozilla used to do for legacy releases. Upgrading is easy, you just install the new release over the old. If you're concerned about issues, just back up the whole directory first.

extensions

It's the loss of extension functionality that keeps me keeping at least
one machine with 3.6.x on it.

Extensions have always made FF attractive, yet many get left behind.

same

same here, they're upgrading too fast for the addon authors to keep up. Firefox needs to slow down and fast. I refuse to upgrade until my addons work properly

Catching Up

Extensions just need to be updated to show compatibility going forward. Extension developers have had well over a year to prepare for Firefox 4. Any extension that was not updated for FF4 probably should not be used anymore.

Firefox 5 doesn't break anything in terms of actual code in extensions over FF4, just extensions that listed only compatibility through FF4. So, folks should grab the Compatibility Reporter Addon (extension) and enable their extensions under FF5, ensure they work, and report them as working. Once Mozilla gets enough reports, they just flip a switch at addons.mozilla.org and it reports back to Firefox that, yes, the extension will work fine with FF5 even though it's only marked as compatible through FF4. The extension doesn't even need updating by the developer or the user. Firefox handles re-enabling it.

Compatibility Reporter didn't

Compatibility Reporter didn't work for my addons. I was lucky to find the developer version on my most critical addon. I recommend turning off any automatic update in Firefox and sit on your current version as long as possible. Updating is simply too risky. These kinds of problems don't happen with Chrome or Opera. with this frequency.

Sure They Do

It just depends on the extensions. Some extensions simply aren't maintained as well. There's no real way around that. When a developer has 12 months to update an extension for 4.0 and doesn't, I wouldn't rely on that extension anymore.

I used to do that too, but I

I used to do that too, but I just upgraded to FF5 and I use Nightly Tester Tools addon and set it to 'force compatability'.
Everything is working nicely.

Wrong locale being auto-downloaded

It's happening the same as in the previous versions.
I had Firefox Portable in Spanish (Spain) [es-ES] locale, and when PA.c updater gets the new version, it downloads the Spanish (International) [es-AR] locale, which is wrong.
I have to manually download and install the right [es-ES] one.

Platform Language

The updater only looks at what language you currently have the platform in, not what language the app itself was in. Did you have the platform in SpanishInternational when you updated?

Update for bank not liking FF5.0

If I edit the 'compatibility.ini' file in the Data\profile directory from this:

[Compatibility]
LastVersion=5.0_20110615151330/20110615151330

to this:

[Compatibility]
LastVersion=4.0_20110615151330/20110615151330

my bank likes 5.0

{changed the 5 after the = sign to a 4}

The only problem, Firefox changes it back on start up. It's a work around until my bank updates its browser list.

Sorry, posted reply in the wrong place.
