How long before Nightly download site is available again?

https://download.mozilla.org/?product=firefox-nightly-latest-ssl&os=linux64&lang=en-US returns:

Did Not Connect: Potential Security Issue

Nightly detected a potential security threat and did not continue to download.mozilla.org because this website requires a secure connection.

What can you do about it?

download.mozilla.org has a security policy called HTTP Strict Transport Security (HSTS), which means that Nightly can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

If you have questions about the update or need help with the process, this is the place to ask! Whether you’re just starting or you’ve already updated and want to share your experience, we’d love to hear from you.

In my previous mail I stated, that after the last Firefox Update last week virtually all my Bookmarks in the Bookmark sidebar AND the Bookmark toolbar have been blanked out i.e. the URL links have been eliminated, the ext is still there with a 'world icon'. Firefox does not let me restore from a saved .json file. Please let me have a solution for this problem, which is absolute first since using Firefox 1 1/2 decades ago. Thank you

My main, daily used computer updated to FF 134.0 when it was released. Two other computers that are less used will not. All are Win10. The two computers were booted up this weekend, but when you try to check for updates, it says they are already up to date. Both are 133.0.3 and have never had update issues before.

Was the 134 update pulled for some reason?

I know I can probably manually download and install the update, but am worried there may be problems with 134.

just trying to remember howto set up Linux with Firefox ,Arduino, and python, python Serial Library plus all the other under lining principles of Ubuntu Extensions , Extensions ! I have a way's to go  !

DO NOT COPY AND PASTE! This is not written correctly! Someone please help with this or correct the code. I tried different ways to do this and nothing works ---- I am beyond frustrated with it.

Security features warning

You may see a warning that “some of Firefox’s security features may offer less protection on your current operating system”.

The sandbox in Firefox makes use of unprivileged user namespaces when creating new processes for enforcing more security. This can be considered a security risk, therefore some Linux distributions have started to restrict its usage and only allow it to work where there is an AppArmor profile.

Such profiles can only cover a limited set of installations paths, including Snap and Debian packages. They cannot however cover some other use cases, such as tarball installations as well as local development builds.

To create an AppArmor profile for Firefox:

In /etc/apparmor.d/, create a file with the name firefox-local

In the file, add the following:

1. This profile allows everything and only exists to give the
2. application a name instead of having the label "unconfined"

abi <abi/4.0>, include <tunables/global> profile firefox-local /home/<USER>/bin/firefox/{firefox,firefox-bin,updater} flags=(unconfined) {

   userns,
   # Site-specific additions and overrides. See local/README for details.
   include if exists <local/firefox>

}

Replace <USER> with your Linux user name. This assumes the Firefox install is at $HOME/bin/

Once you have saved the file, run sudo systemctl restart apparmor.service in the Linux terminal.

Dear Mozilla,

Yesterday I successfully installed my [edited] @ledgreenus.com email on my desktop computer, but today I have no way to access it. I don't understand how it can be hidden like that. I can't do it on my cell phone either. Please help!

My computer is a mac running OS X Yosemite. When I tried to update I got a message saying that the update was not compatible (My operating system is too old?) I had to reset back to an earlier version of Firefox. Is there some way I can make an update that will allow me to keep using Firefox on my machine?

My Firefox browser has ceased working on my Mac Mini (OS X 10.10.5) - have tried several update downloads, all coming back with the message that I cannot update the browser due to the OS I have. What is my next step? Have I lost Firefox as a browser? Suggestions?

Hello, I can't open the security code in my email to log in to the site and the following message appears:

Please advise what to do and what the problem is? Secure Connection Failed

An error occurred during a connection to ... The OCSP response does not include a status for the certificate being verified.

Error code: MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

Please advise what to do and what the problem is. Thanks

I have a Firefox account, I have a Bugzilla account (not used for a long time but was able to log-in back!). I try to understand the detail of some security bugs listed in the Firefox release notes by following the link (to bugzilla.mozilla.org) at the bug ID#... but I always get the reply from that site that I am not logged in with the "appropriate permissions". Actually, when I look at my Bugzilla profile (I am indeed logged in), I can't see any permission for that account. Who defines the permissions? When? What/who could change them? On what basis? Where/whom is the request to be sent to if any? Thanks in advance for the help.

I want to know whether I can update my current Firefox version with my very old desktop setup. I am using the Firefox browser version 78.15.0esr (64-bit) on my iMac 2007 running OS X El Capitan. This notice came up when opening Firefox: " Your version of Firefox will start to have problems on January 14. A root certificate will expire, causing some preferences and other features to stop working. On March 14, 2025, add-ons and more features will also break." Following the instructions to update, in About Firefox window, it checks for updates and then shows Firefox is up to date. I've interpreted this as there's no version available that I can update to. Is that correct?

I've downloaded Firefox on a new computer. Following step #1, there is not green "download as" button so I can't proceed with the installation. Is a "donation" required before installation can be completed. If so, no problem. Kindly advise what I'm doing wrong.

Hello since the last update of 133 to 134 Google no longer works as it should on my Firefox every time I close it asks me to delete all cookies and all data and so I am obliged to reinstall everything each time opening Firefox things work again I went back to 133 and now it's works normaly, but I do not understand why the 134 plant Google mail, Google Agenda, and so on ??? Thanks for your return Yogich

Hi, I'd like to know how to transfer all my Zen info (including passwords, workspace, history, tabs,... everything), from a previous version or from a mac to another?

Thanks. Joel
