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 everyone,

support for Windows 7, 8 and 8.1 will end in September with the end of the ESR 115 branch. Corresponding support article

Is this still the current status or are there any plans to support the old Windows versions for a little longer?

Thanks and regards, Martin

Hallo, ich habe einen neuen PC mit neu Win 11. Da habe ich Thunderbird neu installiert. Alle meine Mails sind bei Web.de gespeichert. Durch die neue Installation sind alle persönlich angelegten Ordner unter dem Ordner: "Lokale Ordner" verschwunden. Wo kann ich diese wiederfinden? Liebe Grüße Hans

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.

For a few days now whenever a new tab opens, either by clicking a link in search results or by clicking a link in an email, the cursor jumps to the bottom of the page and I have to scroll to the top of the page. I'm just getting started with Windows 11 on a new computer. What happened to cause this?

Hi On my Computer I have some locale folders with a lot of mails. Have installed Thunderbird on my Android Mobile and want to see all these locale folders. How and where do I place these locale folders to be able to see them on my Mobile ??? Have attached part of my Mail window to show locale folders. Regards John Gyrud

After a crash I had to reinstall ubuntu and switched to 24.4 where Thunderbird is installed via snap.

I have my old home directory with my old .firefox installation and want to copy my data from the old installation to the newe tb. How can I do this ? brds

I have only my profile file (eg 1b3ylg2i-default) from backup. I copied it into the Thunderbird\profiles folder on the new computer. I have tried changing the information in the parent higher up files (installs.ini and profiles.ini) to match, but no luck. Thunderbird complains that it cant find my profile. The source computer is dead, I have only this file as backup.

Is there a way?

Videos won't load in previously enjoyed timeframe or indeed et all sometimes. timeouts when loading pages. speeds are like 15 years ago even in troubleshoot mode and after refresh. when can I expect improvement?

Firefox no longer starts up. It crashes and stops responding on MAC Monterey 12.7.4 This is as far forward as it will go on this old mac. Everything worked fine yesterday, start up today and no go. I removed the profile and attempted to restart. No joy. So I downloaded a fresh copy and installed it over the old version. No joy. Cannot access profile manager. Removed version and fresh install, still no joy. How to I get it to launch, then How do I recover data from old profile?

How do i get the search URLs from the previous browser to pop up log-ins automatically to favorite sites when beginning to type in the URL ? Like using an old Social Media links - Rumble or Facebook .login ; or an Ebay log in a gmail log in?

Do i need to restart the computer ?

I'm setting up a new Thunderbird installation and email accounts. The account setup fails because it cannot sign into the server. I believe the issue is between the account ID and the email address. They are different. The server requires an account login in the form of wxyz in order to access email in the form of a@bc.de. The account ID password is the same as the email address password. I've tried using wxyz in the account and get smtp connect failure. If I use a@bc.de in the account I get the same failure. This is a working email account that I've had for 30 years. I've tried imap as well as pop3. Both fail the same way.

Hello! After being away from my PC for a few days I tried to open firefox and got this error:

'Firefox is al actief, maar reageert niet. Het oude Firefox-proces moet worden afgesloten om een nieuw venster te openen' aka 'Firefox is already running but not responding. The old Firefox process must be closed to open a new window'

I deleted the application in windows settings and then redownloaded it. The problem persists. What can I do?

King regards, Anton Siemonsma
