Hello,

I’m encountering an issue after migrating my domain and professional email service.

My address was originally hosted by Cabanova and configured in Thunderbird. I recently transferred the domain and email hosting to OVH, which caused the old mail server configuration to stop working.

Here’s the current situation:

The account in Thunderbird is still using a POP server (ssl0.ovh.net – port 995), while OVH uses IMAP (port 993).

I cannot change the server type from POP to IMAP within the existing account settings.

When I try to add a new account, Thunderbird completely freezes after I click “Continue” and never gives me access to “Manual Configuration.”

I also cannot delete the existing account because it contains all my previous local emails that I need to keep.

At the moment, I’m able to send emails from this account via OVH, but I don’t receive any incoming messages.

What I’d like to do is simply update the server configuration to OVH’s IMAP settings, without losing my existing local messages or recreating the entire profile.

Could you please let me know if there’s a way to:

Force an existing POP account to switch to IMAP,

Or safely recreate the account as IMAP without losing local data and without Thunderbird freezing during setup?

Thank you in advance for your assistance,

Hello, I speak french therefore sorry for my english ! I have since 3 days, the impossibility to send a mail. I always receive an error message like this :

L’envoi du message a échoué. Une erreur est survenue lors de l’envoi de l’e-mail : erreur du serveur SMTP. Le serveur a répondu : bluewin.ch mailout-004.p.bluenet.ch Swisscom AG sc774: Blocklisting in effect.

This have been caused as I wanted to send a message to a list of more of 100 personn and the system of my provider (Swisscom Bluewin) blocked me.

I contacted them explained the situation and the have deleted the blocking list and if I go on the email of the provider Swisscom I am free to send message without problem.

BUT in Mozilla Thunderbird i am still blocked with the above mentioned error message !

I have controlled all my SMTP info and they are correct, I have try to disabled the Bitdefender security but no way it remains blocked.

My question is, is this blocking list only remaining in Mozilla Thunderbird and for how long time or someone can help me to cancel this blocking list in Mozilla Thunderbird ?

Many thanks in advance for your help

I updated Firefox on my iPhone 16 yesterday. How can I permanently remove the purple coloring from the top and bottom, and restore a neutral white or gray? Is it possible to restore a previous Firefox version on my iPhone 16, or do I have to wait for another update? Thank you.

While attempting to upgrade my Ubuntu Thunderbird client, I saw the attached screen. I'm concerned because of the unsophisticated style of the page, and the fact that it asks for my password, which makes me think "phishing". Can some trustworthy person confirm that this is a legitimate screen?

Suddenly, when I go to send e-mails (to me, or anyone else) I get a pop up signal that says I can't send it because it might be questionable, etc. What do I do send my e-mails since none of them are "scam" or "questionable".?

I've noticed that I've got both the 32 bit (../Program Files (86)/..) and 64 bit versions (../Program Files/..) of Firefox installed on my pc. I didn't install both and both appear to be the current version. Is this normal behaviour? Only one instance appears in add/remove programs, but if I go to default apps, Firefox appears twice (presumably the 32 & 64 bit versions). If this is not normal, does anyone have a suggestion as to how to remove the 32 bit version without damaging the 64 bit one?

The browser is very nice and fast, but Firefox only shows 8 of your favorite sites on the home screen. Please increase this visibility to 30. The home screen has a huge screen, but there are unnecessary shortcuts like tabs are pasted, and people don't use them anyway. There is also the option to add tabs under the settings shortcuts, but instead of adding tabs when returning to the home screen, a home shortcut can be added, and it would be more useful.

The Government has to keep changing. "for our Security". We have accounts with the Veterans Affairs medical stuff for our medical stuff. NOW we had to move to Login.Gov or another website. It was horrible, but I FINALLY got the Olde Marine & Myself 2 Different accounts (i.e. 2 different email addresses) in Login.gov. VA has continued making changes & since Friday I can not get into "My Healthy Vet

i.e. I go through the steps & when I type in the e-dress & password MY PHONE SHOULD RING with a numeric code.  Once I type in the Numeric Code, I can continue to scramble around trying to access our pharmacy or our 'care team' in the VA system.

I watch the screen, nothing happens. I wait for the phone call nothing happens. I look in my email box & there is a message from Login.Gov that a code was sent to me. NOPE.

I have no idea why. as a cat like nosy person, I am always needing to know why. What is wrong? Is it the government & if so forget it as they most likely won't answer the phone. Is it Charter Spectrum? Is it Mozilla Firefox? (whine) I am beyond my paygrade here. Please someone who can talk to olde Phartes... MAYBE this could be SPECTRUM/Charter??? They are a royal pain in the tush. sending mail to spam that is not & ignoring that I tell them it is real; changing font sizes when I am typing; & other crummy stuff.

As has been mentioned many times before I am sure, it would be really helpful to be able to have a less laborious way to add exceptions but as I have been through the ridiculous process of typing in site addresses manually one by one without having any sensible way to record these addresses already I guess it won't help me now. The ridiculous aspect came from having to take screen shots of the list of sites from the manage data list after deleting everything not wanted, scrolling down a windows worth at a time, copying that screen shot into multiple copies of a graphics program then shrinking each copy of the graphics program and Firefox so each can be seen so I can manually type each address across.

I know I am supposed to be nice but this is just insane. It is 2025. There is a thing called copy and paste. Apparently some people at Mozilla are not aware of this.

Having got that off my chest the next issue is that the deletion of cookies and data only occurs when Firefox is closed. Who closes Firefox? Why would you close Firefox? I currently have 24 tabs open. Why on earth would I want to close them down just so they have to be selected one at a time and reloaded? What is the thinking behind this stupidity?

The only time I close Firefox down is when Windows is restarted for updates (every application) or when IDM needs to update as I found this negates the need to restart Windows (Firefox only).

Other than those situations I am trying to work out how to fit this cookies/data deletion into the normal operation of my computer. There appears to be a lack of a suitable way to deal with this situation. Would it be considered acceptable to just wait for those times Firefox has to be closed? This would be far better than what I have been doing up to now but why wouldn't Firefox delete this data when the last tab for a site is closed? There are a huge number of sites I bring up due to searching for something and close them immediately or after reading what they have to say.

I have been using computers for about 30 years and have long lost the inclination and to be honest the ability to delve deep into them. Today I just want to have them do what I want/need without unnecessary complications.

Have I got this situation right or is there something I have missed? At the moment IDM has been having a lot of updates thanks to YouTube's greed but before that I found I generally only had to restart my computer for MS updates and when strange things started to happen.

Hi, it's many year that I moving manually messages to folders located on a NAS. Everything has always been fine, but today I've discovered that, despite searching funcion is regularly finding all the messages, if I try to open them they show a blank body (see image attached)

I updated my firefox to Version 143.0.4 (64-bit). (I am using Mac). I was trying to change my wallpaper, so I went to the pencil and customize part of the new tab, and when I look at the wallpaper thing, I just see that it says "Reset to default". I didn't see any of the things that said upload image or any of that. just reset to default. I really wanted to change my wallpaper, so is there something I'm missing or something?

The disabled feature still has a picture in the picture when unchecked. How do I stop picture-in-picture for videos playing in Firefox? Yes, went into settings and unchecked picture in picture, yes, the problem still exists.

Tried the PiP mode with YouTube and it didn't work for me. The video pop-up still appears even after un-checking the box in settings; once I click the X button on the pop-up, the video pauses, and will unpause only if I return to the original tab and press play. I've tried the following:

- Restarting my computer - Used keyboard shortcuts to close the pop-up - Blocked autoplay media on the YouTube website

Thanks in advance.

After the most recent Firefox update for iOS, none of my shortcuts work. They’re all still there - or it looks like they are - but whenever I tap on one of them, I return to the page I was just on - no loading, no changes, no nothing. I am still on iOS 18.6.2, but this wasn’t an issue before the Firefox update.

I have two email accounts, one is hotmail.com, the other is on outlook.com

The SMTP for the outlook account works fine, but Thunderbird puts that same smtp details into the Hotmail account smtp. That also puts into the Hotmail username, the outlooks email address.

If I try to send an email using the Hotmail account, I get a message saying 'Hotmail can not send using xx@outlook.com

If I use the settings to make the username xxx@hotmail.com, it puts that into the smtp of the outlook.com address then that will not send giving the same fault. This has only started this last couple of days, nothing changed in the settings.

This only occurs on my Desktop. On my laptop with same settings it works fine.

Thunderbird is showing up to date?

Hello, When I open the window to write a new email the toolbar is missing. I can't see the buttons for "send" or "attach" or any other options.(you can see it on the picture) How can I restore the toolbar? Thank you for your help. Best regards, Bokor Vanessza

Thunderbird 143.0.1 eclipse.

Quite recently I noticed that, in the list of folders, I see 2 "Junk" folders.

On looking at the properties for 1 Junk folder the location is shown as "imap://*********%40gmail.com@imap.gmail.com/Junk",

but properties for the other shown as Junk locates as "imap://*********%40gmail.com@imap.gmail.com/Spam".

I've tried renaming that folder in Thunderbird to Spam but the change doesn't take effect.

What went wrong, and more importantly how can I rename it to see it as "Spam"?

tnx.
