I have Sequoia 15.5 on a 2021 MacBook Pro and have always used FF as my browser. Now, I can't get it to do much more than open. Nothing new happened that I know about, except updates to "Malwarebytes" I have some computer knowledge but not a lot. TIA.

Please help me to get my old version back. This new version has among other things a huge long list of I guess emails with no content just numbers n, I want the old version back please this is too confusing and does not work for me. I was asked and said yes by mistake.

Recovery of thunderbird forced change of message structure. Old tried and true layout became irrecoverable. Install phase of new thunderbird is not the time to go dicking around with the existing data structures. (which you yourself decided on ages ago).

How do I roll back the unwanted "upgrade" of thunderbird ?

Thanks,

Hello. Why doesn't Fiery Fox release a portable version of the browser? What if everything was in one folder and didn’t shit throughout the entire system?

We kindly ask you to start releasing a portable version.

Thanks for your understanding.

Best wishes.

I have a firefox account for many years. my email provider went bankrupt, and I have no longer access to my emails. now I did reinstall firefox on my computer, and wanted to migrate my longterm account. I was able to log in successfully, but there was also an email sent to the bankrupt provider. email is returning immediately, and my account is now blocked. How do I get into my account?

I am on medical marijuana and I cannot use the site because email says I needs a new browser. Without this new browser I cannot get anything from the Medical Marijuana. Everything from the state goes through the email system. There Is a problem with my medical card. It is not working. I have been trying for over a week to get the code I need to open the site and order a new card. I was told that the fasted way to do this is to go through Lost or Stolen card. Cannot get where I need to go because of my email needs a new browser. I am on loop and cannot get off the merry-go-round without help, so please help me.

When I tried to go through, google wanted me to use a new address. bonniegeo346, however [email removed]@ gmail works. Does it matter which I use?

This behavior is beyond annoying. On the desktop version, it will install the update before the browser opens. It should work exactly the same way on all versions. Please get this fixed. I am very tired of being in the middle of browsing a couple of web pages, then the browser decides to close and update without warning.

the most recent update prevents from starting the program

I am repeatedly requested to restart windows in order to finish something previous when I try to proceed with the installation. restarting windows does not help.

How to fix this issue? I am in urgent need of legacy mails. Or can I transfer them to a running system of a second computer?

Thanks for fixing or helping...

I've been using 128.11.1esr. I just tried Release again, 139.0.2. It wakes up with none of my profile settings. No accounts, no email. Just looks like an initial empty launch. I'm switching back.

Should I be doing anything other than just downloading and launching the new version? Or is the Release version really this bad?

Initially, firefox denies my profile registered with version 129 (probably) because current version is 130 in this new computer. I succeed in turning back partly to 129 but probably without some files necessary for snap. The profile is OK but firefox works wrong. Updates are no longer possible and Ubuntu proposes to migrate towards version 24.04 LTS. Is either the good way or an other solution exists ? Thanks to best hint.

I just updated Thunderbird and any email earlier than 2/22/25 is gone. My sent items folder is empty and my address book is empty. Any email containing a link. The link will not work.

I hope there is a way to recover my missing data.

My old PC crashed but I still have the old TB profile. When I copy that to the new PC the mail is restored but the calendar is blank. How can I import the old events?

The other day I received an email from Mozilla suggesting I move from Thunderbird ESR to the Release version (Windows 11). I backed up my profile and installed Release 139.0.2. The following error is now popping up periodically in Thunderbird: "The folder 'Inbox on [myemailaddress]' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I do not think this message is really related to disk space (there's plenty available) or file write privileges since nothing should have changed. I see that others have encountered this message where Thunderbird is trying to compact other folders. However, I did not see a solution applicable to my situation.

Thank you, in advance, for any insight in getting rid of this error.
