I am attempting to copy a FF profile from a Windows 11 machine I created it and am using it on to a brand new windows 11 machine on which I have also just installed FF on. Both machines are at FF 150.0.3. I have done a search online for the methods to do this but they have both failed for me.

The first one I tried was simply copying the profile from the existing (source) machine to the profile folder in the new machine however FF never recognized the copied profile on the new machine (I am using profile manager on both machines).

I then tried copying the profile using the method we used to use a while back to copy profiles which is to let profile manager create a new profile in the new machine, open FF so that it creates that new profile in the profiles folder then delete the contents of that profile leaving it as an empty profile (with the name of the newly created FF profile). Then, I selected and copied the *entire contents* of the source profile I was trying to copy and pasted them into the newly created profile I had just zero'ed out on the new machine so that the new profile now had the exact same contents as the source profile. I knew this copy was successful because it took a while to copy all of the data from the source profile to the new profile and the indicator showed it copying.

Again, FF did not recognize the new profile when I opened FF with the name of the new profile in the prof mgr.t.

Could someone tell me what I am doing wrong or what the problem may be? One problem I had when I first copied the source profile to my 32GB USB drive was a message saying "inbox folder is too big for destination system. " The source profile is 12.72 GB so there is plenty of room on the USB drive for it to fit. I have no idea why FF would have an inbox file so I just skipped it. The rest of the profile copied to completion once I did that but its size after copying was now only 7.65 GB, about 5 GB less than the original. Could this be my problem and if so, how do I fix it? Thanks for any help.

My mouse is setup so that the tilt wheel does Ctrl+Tab and Ctrl+Shift+Tab rather then whatever actions the tilt wheel would normally send, and that has worked fine for years, but now all of a sudden it is not working in Firefox, it's changing the zoom level instead which is not what I want. Firefox must be reading the mouse directly or something, because it shouldn't even be getting normal tilt wheel events.

When browsing using Firefox on a iPhone 17 I sometime do and sometimes do not get a back arrow to return to the page I started from. How can I return to the previous page without having to go to the tabs and re-selecting the web site I started from?

I've been a Thunderbird user for years without problem. However, since May 22, three specific messages continually reappear after deleting them from my Inbox.

I keep my Inbox empty and it stays that way, except for these 3 messages. Removing them from the Trash folder has not solved the problem.

My email provider is netaddress.com via POP3 account. I signed on to look at my inbox on their site via a browser, and the messages aren't there.

I have tried repairing and compacting the inbox, but the messages continue t reappear.

Do you have any other suggestions?

TIA.

I have a few extensions in Firefox but if I click on the extensions button in the toolbar it now takes me to a Personalize Firefox page where, if I click on Extensions, it only gives me the option of turning them off or on and not to activate or access them. For instance, one extension is Volume Booster which cannot be adjusted on this page. How can I get back to being able to actually using these add-ons?

My old provider has stopped supporting my old email address and I have changed to a gmail address. How do I remove the IMAP and smtp settings etc for my old email address? Also remove all trace of that unwanted old address please?

Using Thunderbird with Spectrum email (an old roadrunner address). Changed the outgoing server to the following: Server Name: mobile.charter.net Port: 587 Username: Reefside@cfl.rr.com Authentication: Normal Password Connection Security: SSL/TLS Testing connection fails. I have tried different combinations and once in a while I get that the connection is successful, but email sending hangs and never completes.

Thunderbird aggregates in the same threads e-mails from my employer that are completely unrelated. They are sent in different months, with a different subject, etc. and they end up in the same thread. Clearly, there is something in the header pushing Thunderbird to aggregate them, but this results in a very annoying ordering of the emails.

In my case, e-mail messages are sorted on date with descending order. However, the first message I see in my list dates back to months ago because another message sent few days ago has been merged with the previous one in a thread.

This would not be a problem if the message displayed in the list were the last one added to the thread and not the first one starting the thread.

I have done several searches and read several help pages and discussions here, but I cannot find a way to display threads in the same way the rest of the messages is shown, i.e. latest first. For some obscure reasons, Thunderbird keeps displaying in the message list and in the threaded view (when I expand the thread), the messages in reverse order wrt my selection.

How can I fix this?

Hi,

I am using macbook pro latest one, and when I use firefox and scroll down from my wireless Mouse to the bottom of the page, the scroll bar jumps to the top while working, is there a fix for this.

Thanks

I recently moved from Microsoft Outlook email to Apple icloud email. icloud allows you to create an application-specific password, which I did for email. It works; I can login to email on Thunderbird using my (impossible to remember long) password automatically generated by Apple. I switched the Thunderbird server settings to OAuth, but unlike with Outlook, there was no popup saying a restart of Tbird is required. When I quit Tbird and restarted, it did not prompt for a pw, but neither did it get any new messages. (I sent new messages from another email service to verify.)

I also noticed that OAuth2 was not an available option for the outgoing server, as it was with Outlook.

Does OAuth2 not work with icloud email?

There appears to be no way to change the app-specific icloud pw in Apple, but I will take that up with Apple.

Perhaps the workaround is to use the Tbird saved pw feature?

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

Can't get email from Comcast server any more & a lot of existing emails disappeared. Was on the phone with them & reset ports & checked other things but it didn't work. I can read them at Comcast's site & also send & get them there. Also can you help me forward my email to another email program?
