I cannot login into a website because they complain that I have an old version of PHP. Is that already included in Firefox? I am using Firefox Vers. 143.0.4 on a MacBook Air with MacOS Big Sur, Vers. 11.7.10 Shall I go to the PHP website and download PHP?

Got this error message on recent update and now Firefox doesn't work at all. Platform Version '131.0.3' is not compatible with minversion >= 131.0.2 maxversion <= 131.0.2

Running Firefox on macOS Sequoia 15.0. Afternoon of Tuesday, 8 October, Firefox abruptly ceased loading any pages. I eventually learned of the malware incident and downloaded Firefox 131.0.2 last night and overwrote the existing file. It worked for a brief moment, then also ceased functioning. Have downloaded 131.0.2 several times now, with no further success. Currently dead in the water with Firefox, and stuck with Safari. :(

I looked at the system requirements page at https://www.mozilla.org/en-US/firefox/141.0/system-requirements/ . For Windows devices, the operating systems supported are listed as "Windows 10 or later".

In October 2025, Microsoft officially stops providing feature and security updates for Windows 10. However, they offer consumers and businesses the option of enrolling in 1-year, 2-year, and 3-year subscriptions for Windows 10 devices which will provide another 1-year, 2-years, and 3-years of additional security updates. You can read more about this at https://learn.microsoft.com/en-us/windows/whats-new/extended-security-updates

For those individuals and businesses who will be enrolling devices into the Windows 10 ESU program, will Mozilla continue to support Firefox on Windows 10 after October 2025, at least for those receiving security updates through Microsoft subscriptions? Or at that point will Mozilla consider Windows 11 to be the only supported Windows operating system?

Thank you!

In the last update of Firefox, today, the updated firefox opened without some bookmarks that I had open in the last session and that I don't want to lose. I tried the recovery following your help (Recover user data missing after Firefox update) but without success. How can I recover lost bokmars? Note: This situation has happened more times and if I can't recover the bookmarks, I will have to give up Firefox, which I have been using for many years and stop recommending it.

We are in an enterprise environment and for years we have had disabled automatic updates.

Firefox ESR 128.2.0 has been deployed with defaults and these settings have been configured to override previous settings.

Computer Configuration > Administrative Templates > Mozilla > Firefox

- Custom Update URL = Disabled
- Disable Update = Disable
- Application Autoupdate = Enabled
- Background updater = Enabled

We also have a system proxy configured.

Updates do work if someone goes to Help > About Firefox.

Looks like the update interval is once every 7 hours but how is this triggered?

Everything was normal before the update. When I did the update, the menus changed, the bookmarks disappeared, the new tab key disappeared, how do I get it back to its original state?

After an update of both macOS (to macOS Sequoia 15.0.1) and Firefox Developer Edition (to 132.0b3 (aarch64)), the Bookmarks Toolbar stopped working. The same issue appeared on my Windows PC.

Bookmarks toolbar is visible, I can show and hide it but it does not display any of my saved bookmarks. Luckily, they were not deleted and I still can access them via Bookmarks Menu, which is less than optimal.

The Drag&Drop functionality does not work either. When I grab the opened Tab, drag it on the Toolbar and release it, the Tab gets opened in the new browser window and it's not saved.

Win 11 stopped working on my Lenoovo Yoga due to bitlocker key requirement that does not exist I'm in the process of installing Ubuntu during the installation something went wrong "system program problem detected" which stopped the installation

I got tired of the shenanigans with the latest "upgrades" to firefox (132 & 133) so I rolled back to the last working version (131.02). In doing so, it required me to create a new profile, which I did. Doing so WIPED OUT ALL OF MY BOOKMARKS, SETTINGS, ADD-ONS, OPTIONS, HISTORY, EVERYTHING!!! I now have a blank version of firefox.

How in the world can I get them back???

PLEASE HELP!!!!

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

After last update Firefox ESR 115.23.0 the menu on the website: https://connect.garmin.com/modern/homeis not displayed correctly. Could you fix this? Second question - can you disable reCAPTCHA when logging in to this site?

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

Hello all,

During clean-up of my laptop I noticed 31 language package files in C:\ProgramData\O949. File names look like: langpack-en-US@firefox.mozilla.org, and they all originate from 23-Jan-2017 so I guess they're very old files which might be relevant anymore. As these 10,058 files occupy 56 MB I'd like to remove them from my laptop.

Does anybody know if such task is wise, not harming current running FF v131.0.3?
