How long before Nightly download site is available again?

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.

I've been getting warning messages telling me to update Firefox or security certificates will expire on 14th January. I clicked on Help -> About, but it doesn't check for updates. I also tried going to Preferences, but I still can't see a way to install updates.

I downloaded a version from here https://www.mozilla.org/en-GB/firefox/download/thanks/ I unpacked it into my home directory, but I'm not sure how to install this version.

I'd like to be able to import my current session into the new version of firefox.

Any help would be appreciated.

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  !

I want to update Firefox but also version Firefox-134 causes the same problem as all previous versions newer than Firefox-95: GUI is not started in my Linux system despite all the requirements noted on the Mozilla pages with the release are satisfied. Basing on that I have read and experimented as well as on response to my bug report, https://bugzilla.mozilla.org/show_bug.cgi?id=1938497 I suppose that the new versions of Firefox are not able to start GUI using libGL backend GLX and they require LibGL backend EGL only. This requires libEGL version and other associated libraries that are present only in newest versions of Linux distributions like Fedora-41. These new versions are for new hardware and it is pointless to install them on older hardware because they would work probably ineffectively and cause problems. Linux is very customizable and users introduce adjustments and install software created by themselves, for years. That is why an update to radically new version of the Linux distribution is justified after buying a new computer. This would be required for making the Firefox-134 binary provided to run with GUI as well as for possible compiling it from source.

That is why I would like to ask for consideretion of submitting Firefox-134 binary statically linked (at least the libraries that are required for GUI) so that it will work with GUI on older Linux systems obeying the requirements noted on mozilla pages with Firefox releases, assuming 4-8 GB RAM is available.

Hi, so i have a question: what are your plans to support windows 10 after 2025? How about windows 10 iot ltsc which is supported until 2032? Will firefox still be supported after 2025 on the iot ltsc version? Or will i have to switch to linux?

I downloaded the latest version of Firefox. The directions tell me to open the file that i just downloaded, which is fine, except that I don't know the file name or location. What is it, and where is it? or how do I f find out?

Hi,

Thanks

PC desktop running Firefox 133 /Ubuntu. (22.0) true or false.............................

even though I completely remove my current version of Firefox and reinstall a new version. my current malware infection will "reinfect" the new install ????????????????????

In older versions, there was an option to refuse updates, disable checking and any reminders.

In new versions, you kind of accidentally removed this option. And now a reminder "update update" and a green indicator regularly pop up in the right corner.

I previously deleted all Mozilla servers through the config file, disabled checking for updates. But it still restored the settings and now offers updates again - which irritates me terribly.

I supported Mozilla for many years and considered this browser to be something conservative, it has always been aloof from cumbersome and spyware browsers like Chrome. But your latest actions are disappointing.

The decision to update or not has always been and will be on the shoulders of the user.

I don't care about security policies, patches or bug fixes\Super new features.

With your actions, you only generate unnecessary negativity and lose the most loyal and old users. Today is the day when this browser will no longer be on my devices, you have achieved your goal - congratulations, you have won.

A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`
