I just updated my iMac from Mojave to Catalina 10.15.7. I thought Firefox would provide an update to convert the esr version to the standard Firefox browser since I am no longer using Mojave, but the next update is 115.15.0esr. Is that correct? My understanding is that the esr updates are just for computers using older operating systems through Mojave. I did not update to 115.15.0esr since I am not sure if that is the right version for Catalina. Any information and assistance you can provide me is greatly appreciated. Thank you.

Hello, I've looked over many threads to try and find a solution to the problem. When I booted up the computer this morning I tried opening up Firefox, my daily driver, only to find that it won't open. I tried rebooting, I tried uninstalling Firefox and reinstalling, rebooting again, nothing works. I even went so far as to downloading a windows 10 reinstall program that runs of a USB. It's one that preserves your programs, but updates everything possible in windows. Now the computer is back up and Firefox comes up with the same error message.

What do I have to do to get Firefox working on my computer again????

I converted as advised and then updated to the newest version. I lost everything except the messages: the Address Book, Tags, Message Filters, and Folders are all gone. This is a disaster after 15+ years with Thunderbird. It started when I copied the folder "profiles" from my laptop to my PC for the 1,000th time. Is there a simple step-by-step solution? Without the history or apologies etc. etc? Just "do this?" My solution now is to do all my email on my laptop. Ugh!

Ever since the last two updates my saved cookies keep disappearing. It's a pain since I have to log in everywhere when it was automatic before.

I'm on an imac desktop computer with the latest firefox browser.

I would like to install Thunderbird on two separate Win7 networked computers and use the same "Thunderbird Data" on a NAS for both. I already use the Data on the NAS for computer number 1, but trying to run Thunderbird on the second computer gives the well-known error "Thunderbird already running..."

The latest update of Firefox for Android (130.0 (Build #2016041319)) removed the ability to swipe away the "Tab Closed Undo" bar that shows up when closing a tab.

If a user closes the last tab, a purple-ish bar appears at the bottom of the screen that reads "Tab Closed" on the left and "Undo" in a different font on the right. In previous versions of Firefox for Android a user could swipe away this bar to make it go away. In the current version that is no longer possible and I would really appreciate having that back.

(Honestly I would actually really appreciate never seeing the bar since I can access closed tabs via the History and I really dislike the bar.)

I was told by support rep Ed to resubmit this.

Firefox is broken. Submit buttons are not working, & recaptcha doesn't work on some sites. All is well with other browsers.

HELP!

The last few days my computer has a long time connecting to the internet I saw a notification from Mozilla that they updated some type of program that might effect the connections that it might take longer to connect well it does and by the time it connects it say to long to connect so no connections at all before they did this upgrade or what ever my computer always connected johnny on the spot now it doesn't so the upgrade just don't work I think I saw something like a AI thing any ideas or what I am about ready to go to another browser program it's just not working for me I have windows 11.

Hi,

I just updated my firefox browser. And had numerous tabs that were still open. Usually when I have update it I go to history and click on recently closed windows/tabs and everything comes back on.

But this time, there's nothing there! I'm missing all of the windows/tabs that were opened before. I look in my history tab and there's nothing there either from the time the firefox was updated.

Before Firefox had something called restore previous session. And that's not there either.

Can you please help me get my old tabs/windows opened again? Please

I hope I’ve chosen the correct category. I believe this qualifies as a bug following the recent update.

When I opened Thunderbird today, it notified me about the update. While Thunderbird successfully fetches new emails, it fails to display them correctly.

As shown in the screenshot, the area where the email content should appear is completely white. Additionally, it incorrectly displays an attachment from an old email that has nothing to do with today’s email (10:13), aside from the fact that both were sent to me.

When I click on other emails in the same inbox, the content area doesn’t change—it remains blank. However, if I switch to a different inbox, everything works fine.

I’ve also double-checked using my phone’s mail app, and I’m able to open the email in that inbox without any issues.

I’m unsure how to fix this. Could someone more knowledgeable help me out?

My original install crashed, and kept saying to close, and would not stop.... I tried uninstalling all of Firefox and when I install the new clean version, the messages continue and will not install the application. How do I completely remove Firefox and install a fresh copy?

We've got around 2000 AD-joined windows 10 boxes, with TB as the mail client, for years. Users are connected as domain users (ie, non-admins). Now IIRC, first TB version installed was 60. TB was updated throughout the years automaticall without a hitch, up to and including version 115.x.

With the advent of 128 we had started receiving calls from users stating that a message pops-up asking for credentials. Taking a closer look we discovered that each and every installation needed admin credentials to be able to do the upgrade to 128.

Is this a bug or normal behaviour? It is definitely a problem, especially for small organizations that do not know how to install manually an MSI of the latest version.

I recently updated to v130. I'm having the same problem that so many others have, "Firefox already running, close Firefox". After updating to v130 I had to go to Task Manager and delete 19 Firefox running. It's only been a few days ago and I checked Task Manager today and deleted another 13. After updating to v130 many of my add-ons are showing up in the Menu Bar. I have used Add-ons Manager to drag and drop, but it doesn't work. I have specific bookmarks that should be in the "Bookmarks" section" but they are also showing up in the Menu Bar. I had to re-select my screen choice because it had disappeared. I use DuckDuckGo for my search engine and in the past I was able to choose a separate search bar, but that too has disappeared and I cannot seem to fix it in settings. So many problems after updates, but this one seems very bad. I use Windows 10 on my desktop PC

Please Help, Rhonda

Hi Team,

Can we get details regarding the latest ESR release (128) installation issue in Windows 2012 R2 server.

We are facing failure issue of ESR 128 x64 in windows 2012 R2 server.

Regards, MM

I have installed Thunderbird on a new PC desktop running Windows 11, copied all the server settings from my Mac laptop that are working correctly, yet i keep getting an error message that "Thunderbird failed to find the settings for your email account". My ISP will not provide detect support for your client, a "third party provider". What do I need to do?

I've noticed that after a few months Firefox ESR will go from being one specific version to two different version tracks. Eventually the older track is removed and the newer one is continued until it then splits. Can someone tell me why this happens and is there an easy way to swap over to the current track? I've included an attachment of what i'm talking about.

Ah, the sweet irony of it all.

The easiest way of downloading updates and accessing the Mozilla Support pages is using Safari!

Using Firefox, the updates don't download fully and accessing the support pages takes an age, if at all.
