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?

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

I recently got a new computer, Apple iMac. I'm trying to transfer all my bookmarks I have on my older HP computer to the newer computer Apple. I downloaded the Firefox browser to the iMac. I see where there is a link to transfer bookmarks when I loaded the browser. But, when I click on the link, nothing really happens? There is no transfer of my bookmarks for my old computer to the newer computer. My OS with my older HP was Windows 7. My OS with my acquired Apple is Monterey. Can someone be of help with transferring bookmarks from one computer to another? I have many bookmarks so it would be very helpful to be able to make that transfer. Thank you.

In an office, trying to refresh after someone left. When we try to change settings, Firefox asks for a password which we don't have. So I tried uninstalling and downloading a clean copy but Firefox recognizes we've had it before and loads the new version with all the old info, so we have the same the same problem trying to make changes.

How do I get an actual clean copy with a new account?

I had to reinstall Firefox on laptop B. Initially I copied the profile folder back, as I had a recent backup. However, when I sync'd, it deleted a bunch of extensions - which then sync'd and deleted them from laptop A too.

I got them back (manually) on A, deleted the new installation on B, then reinstalled and resync'd (without copying the profile folder). Same thing happened, except as I wasn't coming from the profile, I'd also lost a bunch of settings. So even worse.

My theory (based on the popup about syncing with a mobile device) is it is, for some reason, syncing with my Android phone config (which doesn't have all the same extensions, as they're not compatible) instead of my browser on A.

Has anyone else encountered this? Any solutions?

Hi all,

For the last week or two, (since version 1.30.x or so) my Mac running Sonoma (in aarch64) Firefox hasn't been able to update itself. Now I have no VPN causing woes (like Nord) I do however, use Adblocker Ultimate and Ghostery.

So I do the manual update, and find that the link doesn't "automatically start" the download. So I tell it to download manually with the big blue button... no dice.

So I copy the link location:

https://download.mozilla.org/?product=firefox-latest-ssl&os=osx&lang=en-US&attribution_code=c291cmNlPShub3Qgc2V0KSZtZWRpdW09KGRpcmVjdCkmY2FtcGFpZ249KG5vdCBzZXQpJmNvbnRlbnQ9KG5vdCBzZXQpJmV4cGVyaW1lbnQ9KG5vdCBzZXQpJnZhcmlhdGlvbj0obm90IHNldCkmdWE9ZmlyZWZveCZjbGllbnRfaWRfZ2E0PShub3Qgc2V0KSZzZXNzaW9uX2lkPShub3Qgc2V0KSZkbHNvdXJjZT1tb3pvcmc.&attribution_sig=abdb7ecea583af9de12c794aa139112efc9c10dbce0cd8382f668154ec651a81

If I open that up in a new tab... it STILL doesn't work. But as soon as I remove the last section:

.&attribution_sig=abdb7ecea583af9de12c794aa139112efc9c10dbce0cd8382f668154ec651a81

It downloads fine.

Incidentally, it downloads fine in all the other browsers (Brave, Safari, etc). Also the entire Mozilla support site, if accessed using Firefox, looks as though no CSS is ever loaded. It's been like that for days. Everything else works fine. Just Mozilla sites.

Is anyone else having this problem? It was updating fine until recently.

I was a huge fan of Fonts Ninja extension. I downloaded it from ADD-ON web page. It stopped working after a Firefox update, circa 2023. To this day, I am not able to enjoy this wonderful (typography identificator) extension, even tough I am able to dowload it and install it. What´s wrong? Yours, Simon

Currently on 131.0.3. Started having this issue around the time 131 dropped.

I press Ctrl-shift-O and bookmarks manager won't open. Bookmarks manager opens normally if I use the menu to open it. Keybind won't work in troubleshooting mode so I know it's not an addon, and the hotkey works fine on other computers with Sync enabled so I know it doesn't have to do with my synchronized settings. Also won't open with a fresh profile so I am very hesitant to reset all my settings.

I use this keybind multiple times per browsing session so it has had a major impact on my usage. Not sure what to do. Please help!

I'm going to try a graphics driver update in the hope that helps. This is on Windows btw.

What the hell were you thinking with this latest update? You seriously had the nerve to remove basic, essential features like the Refresh button and the + sign for adding a new tab? Are you kidding me? These are core functionalities that make browsing smooth and convenient, and now they're just gone?

How can you possibly justify this? Did anyone over there stop to think about how frustrating this is for loyal users? It’s absurd to think that a browser as well-established as Firefox would pull such a ridiculous move. A refresh button—seriously? One of the most frequently used features in any browser, and you thought it was a good idea to just take it away? What’s next, are you going to remove the back button too?

The audacity to push an update that cripples usability is unbelievable. This isn’t innovation; it’s downright stupidity. A browser is supposed to help users navigate the web efficiently, not make us jump through hoops just to perform basic tasks! How out of touch can you be to mess this up so badly?

Get your act together and fix this mess. Stop making changes for the sake of change, and start listening to your users!

Thunderbird performed an update to my email and ALL Calendar entries are now gone. Completely Empty. Past appointments, meetings etc present and future. I have been using the Thunderbird calendar for over 18 years. I need my info back if possible. I don't have the bandwidth to "find" and "fix" on my own. HELP - quickly if possible. All was working just fine 6 hours ago.

I was able to send emails on Oct 9 but haven't been able to since then so I assume there's something wrong with your Oct 10 update. I can receive emails. I selected 'reply', entered a comment. My only options after that were to save as a draft or cancel changes.

I chose installation and updates as I believe it best suits my issues. On my PC running windows 10 pro I downloaded vpn, relay and monitor apps at various past dates. My account information on the PC was deleted I do have the Firefox browser for IOS but, I did not down load the vpn, relay or monitor apps on that device. My issue is that when I log into my account I cannot find the missing apps to re-install the vpn, relay and monitor apps. Is there any way for me to gain access into the account that allow me re-install or add to my existing account. I have changed my primary email address and deleted the old email, which I still have access to if that is any help. Any help or advice would be greatly appreciated. A.W.

I have unsuccessfully followed to the best of my ability the instructions located here for migrating the Thunderbird profile folder to a new PC: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer (my new operating system is Windows 11 Pro). The folders appear to be installed on the new PC when I examine them through File Explorer, but they don't load into Thunderbird when I open the app.

I read somewhere in one of the comments to this article that it is critical that the versions of Thunderbird on both the old PC and the new PC must be the same. But am confounded as to how to do that. When I look for updates to the version on the old PC, I am offered version 115.10.1. But when I try to download Thunderbird for installation on the new computer, one is only offered 128.3.1esr. How, may I ask, can one synchronize the versions of Thunderbird on both computers then? Where can I find an older version of Thunderbird to download onto the new PC? Or get the version of Thunderbird on the old PC to update to the latest release?
