You want to update to Firefox 20, as it contains important security and performance fixes.

Sorry, I don't want it. I didn't ask for it to download, and I don't run programs I haven't chosen specifically to install. Is there a way to get my old Firefox back? If not, I won't be using Firefox anymore. Thanks!

Do you have Firefox set to automatically install updates?

Updates are released every 6 weeks or so to bring performance fixes, security fixes, and other improvements to release. you can read the release notes at http://www.mozilla.org/en-US/firefox/20.0/releasenotes/

I get the impression that I'm responding to automated replies here, but just in case you're a real person: All I want to do is to stop this automatic update and go back to the version of Firefox that I had. I haven't restarted Firefox since it gave me that updating message, and won't until I fix this problem. I don't want version 20 with whatever unknown problems it will have. Version worked fine for me. Thanks.

I don't know why you would assume there are unknown problems in Firefox 20. It's been out for weeks, and a significant majority of users have already upgraded. Even for the security fixes alone it's important to update Firefox. Just because there is an update doesn't mean you need to assume it's bad. Not updating is often worse.

Okay, can anyone else help me?

In the meantime, I've downloaded Opera and am looking forward to seeing how it works for me.

You'd be better to move on to opera, or any other browser that you'll at least stay up to date in.

I would imagine that like me he has activated the setting to not check for updates....yet he still receives them. Your reply does read like an automated response. You assume he doesn't know what he is talking about while it seems clear to me he does. Why didn't you tell him how to find the "package" and delete it, or reverse it? I run nightly because its 64 bit, but don't want the updates because you never know what addons won't work with a new version, or what new problems they will breed. The one I have is very stable, and I do allow telemetry, BTW. I also am responsible for my own security and quite aggressive about it too. For some reason when I used the profile manager for the first time, even though I made the settings the same as to not wanting updates, I got one now waiting in the background for a restart to intrude into my hard work at configuring the browser to my taste. I wish I knew how to kill the thing before it installs but won't find any help here. Fidofootage asked how to roll back to another version but got no answer. He asked how to eliminate the "package", but got no help; and I'm quite sure he told the browser not to update in the first place, as I did, but got the update anyhow.

Those Nightly builds (especially the unsupported 64-bit on Windows) are not meant for regular users like yourself but for devs and serious Testers. Also sticking with a random build is not really using the Nightly test builds. The Nightly channel gets checks pretty much every day and as a result gets a update each of those days as a result. If you do not want daily updates then do not test this unstable Nightly channel.

What OS are you using as Linux and Mac OSX has had 64-bit release builds ever since Firefox 4.0. For Mac is is a dual download while for Linux you can get it on ftp.mozilla.org

Also 32-bit release builds works fine on 64-bit Windows.

I know what Nightlies are like as I have been primarily testing them ever since Firebird 0.6

Win 7. I have Linux as an alternate OS but don't use it much and didn't know that 64 bit was available for the OS. I know 32 bit releases work fine on 64 bit windows but they don't provide the same graphic "experience", unless I am missing something. Besides, I don't mind in the least contributing to the Mozilla "experience" by enabling telemetry feedback. I just intend to protect my "domain" as much as possible being a rugged individualist! When Firefox comes out with a 64 bit browser I will quit using Nightly. What are they waiting for????? BTW, I humbly consider myself a "serious tester." If "regular users can't be serious testers then, well, what use is the program to refine the "program"? Anyhoo, thanx for the response. I didn't expect it.

There are a few misconceptions, fallacies in your posts:

1. Firefox 32bit runs perfectly fine on Windows 64bit. Your get the same graphics experience, Javascript Engine (actually the one in Firefox 32bit is faster than the 64 bit version), etc. There is no advantage to running Firefox 64bit over 32bit. 2. Don't run nightly without updating. That's a horrible thing to do. Not only do you not get security updates, you are running unstable, untested software that is way out of date. Run Firefox 20 if you aren't willing to risk instability in Firefox nightly. 3. you can enable telemetry on release, and we love to have that data as well :)

One of the reasons is that not all plugins are available in a 64 bit version and a 64 bit browser will only work with 64 bit plugins.

On Mac Firefox is a 32/64 bit universal binary and can be started as a 32 bit application if necessary.

OK. The same graphics experience? I'll have to see that for myself. But if you say so, its worth a try. Thanks. You say it is unstable, but that is not my experience, and, My Security Concerns, are owned by ME, not anyone else. I've been warned by various progs for years, no, make that decades, about "security" concerns and have never ever had a breach. Does the "web" know me? Sure! You can't hide. But, how much do they really know? One might constantly obsess over privacy and security but when it comes down to it privacy is only available to one who doesn't use the internet.....somewhat! Use of proxies and the Electronic Freedom Foundation guidelines are a good start if you want to protect you privacy and security. In the days of pixelated identifiers, i.e., pages identifying visitors based on assigned unique configurations of pixels in a web page, it gets damn tricky. I did, by the way, swallow the nightly update that was pending with no deleterious effects, to my knowledge. Thanks Mozilla. But I have to say, Tylerdowner, you sound like you have a slavish devotion to some kind of Mozilla based catechism or dogma. Smilee!

Please don't confuse Privacy and Security. Security is the ability of websites to use holes and vulnerabilities in your software to install unwanted and malicious software, steal personal information and password, etc. Privacy is the protection of your personal data from untrusted parties (who don't use security holes to gain access to such data). Privacy is, yes, mainly your choice, security is something you can never be too secured against. This isn't dogma, this is common sense.

Anyway, this thread has turned into bashing and name calling, so I'm locking it. If you have a problem in Firefox that you want support with, please start a new thread. After updating firefox.
