My Firefox 78.15.0 ESR on my 2009 desktop iMac is corrupt. I removed everything to do with Firefox and attempted to re-install. Cannot find this Firefox version on your website. HELP, please………..

So, as has been announced, FireFox 115 ESR will get updates until septempber 2025. This deadline has been extended multiple times. What factors are being taken in consideration when deciding whether to extend support again? With server 2008 updates you can get windows 7 up to date until 2026, sort of. Ending support in september would still be sad, because people too stubborn or not willing to upgrade probably still wont when support of firefox ends. I am a firefox on windows 7 user myself too, and it would be sad if they dropped support. Ill have to use a backported fork by the community

So thats my question, what factors matter in terms of extending 115 esr support again?

I was on the ESR channel and after the recent updates to 142.01 or 141 the ESR is missing from the about Firefox. I had got the tab groups option a few updates back and liked it. This latest update changed how a tab group collapses, instead of showing only the tab group name and collapsing all the tabs it leaves one open wasting space when I have several other tabs open. At least I don't see any sign of the annoying AI junk getting in the way yet. I thought you had a choice to stay on the ESR channel according to this link and others. https://support.mozilla.org/en-US/kb/firefox-support-windows-10-end-support I'll probably be forced to update to Windows 11 to do my taxes next year but I thought at least I could stay on the ESR channel to avoid new features getting in the way.

I am aware that Windows 10 will continue seeing support for the foreseeable future, but what about older versions and builds of 10?

I ask because I'm currently on a machine that physically can't update beyond version 1909 build 18363.1198 due to an issue that occurred on my machine in November 2020. So I've been stuck at that version and build of 10 for basically the last five years. While I'm trying to see if I can update it to 22h2, the last known version of Windows 10 with the hopes of enrolling in the extended security updates, that may not be feasible due to how old the mahcine itself is. Will Firefox continue to support all versions of 10 for the foreseeable future and not just those on the ESU? If so, great. If not, what version will be the last that can support the version I'm on? I don't have a Windows 11 machine yet on a full time basis (I'm testing an 11 machine out, but I may not end up keeping it) and I prefer 10 to begin with, so I would like to know when I need to stop updating Firefox itself, so that I can be sure I'll be able to keep using the browser with my current OS.

I have Windows 7 which is not supported now (older Toshiba laptop). firefox suggests using Firefox ESR 64-bit. I think it downloaded, but not sure. What can I do about this and be able to use it?

Hello,

I'm using Linux Mint 17.3 (Rosa). Firefox version is 78.7.1 esr-linux amazon. I want to update to the latest Firefox that would work with this version of Linux Mint. It seems maybe this can't be done anymore. Looking at Firefox software on the machine, it says it's Up to Date. I really still want to update it. I know Mint 17.3 is really old and will replace it. Firefox does work, but I'm now getting sluggish Internet because Firefox can't handle all the security requirements. So many web pages don't very well anymore. Can someone help?

Because the economy, inflation, and lower incomes are still a major problem, many users like myself need to continue using old computers that can only run Windows 7. So we need Firefox ESR 115 to continue being supported with updates for at least a couple more years.

There are no OS updates available for my computer hardware (nor have there been for quite a few years), just to quash that right off the bat.

The last release for 10.11 is 78.15.0esr (64-bit).

A number of websites do not load or outright refuse to load (the whole cloudflare hosting system, imgur, daily motion, youtube nags about it, even the login system for mozilla support renders quite oddly).

So I'm requesting an updated release. I realize there may be limitations due to libraries that have similarly abandoned 10.11. Thanks.

Firefox does not work with many websites any more. I constantly get notifications from websites telling me I need to update my browser. I am not able to download many forms and some videos no longer work. I've tried to update but I'm on some ESR & still get notifications that my browser is not supported by many websites. I have windows 11 (chg from 10 in March 2025), 64 bit but it says my system is not sufficient & that I'm running windows 8 which I am not. I have made the decision, after over 10 yrs using Firefox, that I'm going to move everything to Chrome. I HATE that I have to do this but I can't get any support/help from Mozilla or firefox to correct whatever the problem is. If anyone has any suggestions, I would appreciate. Done

I am getting a lot of web client exceptions with version 141. How Can i go back to version 139. This is for my work software. I have no power to make changes to the software. If I can go back an not have automatic updates that would be great. Will I have to delete firefox and download an older version.

Hi I have an old version in my mac (os sierra 10.13.6). Is it possible for me recieving the update ? Can I still use Firefox 115.26.0esr?

Kindly

Petra Torresan

What could I expect from such a move..?? Would it bork my current setup etc..?? Can I still refuse updates until I see how they fare..??

Anything else I should be aware of..??

Thanks.

How can I download an older version of Firefox ? Version 140.0.4 is full of issues , i.e. slow loading pages that were faster in the old version , shrunk images on some sites , log in problems on others.

I am trying to install the new extension for Mac OS below 10.14.I have Mac OS 10.13, and this laptop cannot update to any newer OS.

I received the message that Firefox is not longer supported on my OS. I tried to download the extension to fix this issue.

I got to where there is a Firefox icon with an arrow pointing to the Applications folder icon. 

Now instructions. What am I supposed to do?

I am skilled in MANY things, not computer set up stuff.

ALSO - I clicked on something that seemed logical at the time. I do not recall what it was that prompted me to choose "existing" program (Firefox). or to not choose the existing program. I don't understand the process and clicked on "existing". I fear this was the wrong choice. Most web pages will not load. But if I click on the fox icon at the top of the window, it now shows a list of recently closed tabs, and if I click on the website listed on that page, the website will open.

Any assistance is appreciated.

Hi Mozilla Team / Community,

We understand that Firefox 115 ESR will receive security updates until at least version 115.27.0esr in August 2025.

We currently have a number of devices still running Windows 7 for legacy application reasons and rely on Firefox 115 ESR as it's the last version to support that OS.

We need to plan ahead, so could you please confirm:

Will Mozilla continue to support Windows 7 with Firefox 115 ESR updates until August 2025?

Or is support for Windows 7 ending sooner, even if 115 ESR itself continues?
