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?

Hello, I am experiencing unexpected behaviour with local storage in Firefox Portable ESR 102.1.0 on Windows 11. In particular, the data is not deleted as expected after closing the application, even after clearing the cache in my code, the data persists when I open the application the next time. This behaviour is observed under windows10 but is common under windows11.

I suspect that this issue may be related to:

• Interactions between Firefox Portable's cache management and Windows 11's system-level caching
• Specific behavior of the ESR 102.1.0 version on Windows 11

I would appreciate it if you could investigate this issue and provide any insights or solutions.

I'm a retiree in my mid 70's...I've heard that Firefox will stop extending ESR's past March of this year. I'm not in a position to buy and update all my software and laptop & desktop the latter can't go any higher on Mac OS. So I'm asking that you please consider continuing support for older browsers. My browser is Mac Safari 14.1.2, I would be OK making a good sized donation to Mozilla or paying a monthly subscription if necessary to be kept updated on Firefox ESR's. I've seen other inquiries on your site from others asking about the same thing. So please consider my request and let me know if there's anything I can do to get your continued ESR support for my computers. It would mean a great deal to me and I know quite a few others as well...So please pass my thoughts up to management and I will hope for the best...

My Thanks,

Tom D.

My company relies on another company for our VM using Amazon Linux 2 and installs Firefox ESR from Amazon Linux 2 extras. We have 115.18.0esr and were getting notifications at the top of Firefox saying this would stop working on 14th March. We got 128.7.0esr but it core dumped on loading even in safe mode and when creating a new profile. So downgraded and then found another coworker faced same issue so go him to also downgrade. I then went to recreate my issue get logs and screenshots to provide to my supplier but 128.7.0esr has disappeared from the amazon linux yum repo and the notification about the need to upgrade before 14th March has also gone and gone from co worker machines. I think it was needed for plugin and cert issues but I am not sure. I realise I should reach out to the supplier for them to then contact Amazon and find out what the issues are from their yum repo and see if it is anything to do with their provided vm. But has anyone got any info on the reason to upgrade from 115.18.0esr so I can add to the issue? I know it's EOL but the message was specific and came from Firefox and links which took you to info about why it was needed but it seems weird the notification has disappeared.

New update to Zen browser this morning, indicated that Roboform extension needed to be updated. Uninstalled,re-installed Roboform extension. Zen browser does not seem to use the the extension - no offer to fill passwords, etc.

Can I revert to previous version of the browser?

Hi All We are utilising the Firefox ESR 115.21 (current release) on some devices to keep them as risk free as possible while we work on upgrading them. I was wondering if the CVE that our monitoring software is reporting as currently open vulnerabilities against version 115.21 are correct and if so, is there any plan to mitigate these in the upcoming ESR between now and Aug 2025? I would just like to understand so I can document on our end appropriately. Thanks in advance.

Mozilla Firefox ESR (x64 en-US) (ver. 115.21.0) CVE's: CVE Details - Risk - Date of Release CVE-2024-7518 6.5 Aug 7, 2024 CVE-2024-7520 8.8 Aug 7, 2024 CVE-2024-7528 8.8 Aug 7, 2024 CVE-2024-8385 9.8 Sep 4, 2024 CVE-2024-8386 6.1 Sep 4, 2024 CVE-2024-9397 6.1 Oct 2, 2024 CVE-2024-9398 5.3 Oct 2, 2024

为什么 Firefox 115esr 会把 User Agent 中的 Windows 版本号强制设为 Windows 10？

我是在 Windows 7 下使用 Firefox 115.xx.x esr ，不知从哪个版本起发觉 User Agent 中的 Windows 版本号强制设为 Windows 10 ，请问这是为什么？ --- I am using Firefox 115.xx.x ESR on Windows 7, but I noticed that starting from which version the Windows version number in the User Agent is forcibly set to Windows 10. Can you tell me why?

I accidentally downloaded a newer version of Firefox on my iMac but it is too old to run it. Now I have no way to download an older version that I use to have. Don’t have any suggestions? Thanks

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?

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?
