My wife discovered today that all email had disappeared from her inbox! She doesn't know how or why and neither do I. She is running Thunderbird 1.15 under Windows 7. I have already tried the Windows restore function on the INBOX and it didn't work. Tried a number of other methods and none worked. In looking around the Thunderbird directory and noticed a bunch of files named nstmp-1, 2 3 and 4. nstmp-4 has this morning date-time on it and viewing it in an editor it seems to be a backup of the INBOX. Is this true, and can it be used to rebuild her INBOX.

I have been using [edited] @comcast.net as user name for Firefox account. I want to delete that email because I'm leaving comcast ASAP. I read instruction that say add a new email name as a secondary account and then delete the primary one above. I entered [edited[ @gmail.com. I got a message that said that account already exists. Since I didn't know that or remember any password for it, I entered [edited] @gmail.com and said "forgot password." I changed it Now Firefox won't let me in using the [edited] @gmail.com account. Would appreciate any help you can offer.

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

First I got problem.with my laptop. I went to a service shop, but the technician caused me to loose the old files of my e mails. I seriously need help to get my old e mails accessible

I have set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE in both Thunderbird and Betterbird.

I have created the file C:\Users\MYNAME\AppData\Roaming\Thunderbird\Profiles\r2v9k1zw.default\chrome\userChrome.css

I have successfully entered css into that file that work as expected in Thunderbird v115.12 and has for the past several versions. But I have NOT been able to do anything in that file that works with BetterBird. In fact, using the inspector, I don't see userChrome.css even being loaded! I have also tried starting the file with '@namespace html url(“http://www.w3.org/1999/xhtml”)' but that makes no difference either.

How do I get BetterBird to recognize the userChrome.css file?

I am recently getting messages from FireFox on the right hand side of my screen. See uploaded image.

The information is totally useless and interrupts my work.

How can I get rid of this junk.

If I can't, then after many years of Firefox, I switch to another browser as my default.

Thank you!

I used to use chrome. There, when i add a bookmark, the title and the URL are prefilled. Which is very comfortable. Why is this not a feature in firefox? I always have to copy paste the URL and enter an own title. Chrome has become very slowly on some websites, while firefox does not slow down on those websites at all. So i want to stay with firefox. Good job, team. But the bookmarking UX is improveable.

Hi

I'm trying to link my business email with Thunderbird but it failed to connect with my server .

Attached is a screen shot

Thank you Marwa

Hi all, I need to solve a problem that is a bit annoying. I am on ubuntu 22.04 and using SNAP Firefox 127.0 (64-bit).

When I am prompted to select a file, for example to upload an image, the file picker is shown. However the thumbnails are so small(and right now I only see the image name) that I cannot see what's the content of the image. I managed to show a preview on the right of the single selected image by modifying an option in about:config. However it is still a pain to find the image I am searching for when I have a long list of images. Is there any way to enable zoom on the list of thumbnails so that I can preview the contents of the images? I don't understand why there is no option to customize the display of the file list. In the attached image I show how it looks right now.

Thank you

I have received an email from Microsoft advising that from a date in September third party apps will no longer be able to access outlook email accounts. Does this mean I will no longer be able to use Thunderbird - which has been my preferred email client for many years? Thanks Nigel

Can't get out of offline mode. It happen once previous but an icon was available and got back on. Now going to settings and nothing works. Surprisingly found nothing with Google nor Mozilla support. No email; big problem.

The offline option does not give off or on but option that I don't understand.

The file at the top shows offline and there doesn't seem a way to change (no check mark).

The moderator, 10 years ago, said uncheck on life or two blue line. No such think.

Computer is connected to internet. Shut down MAC and restarted. Still OFFLINE. I must be online but cannot download my messages.

Please help

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
   If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

Best Regards, Margaret Mackisack

Almost daily I get a message to download or dismiss update. When I dismiss the message, it continues to pop up. When I hit download, nothing happens. This is locking up my computer at times & slowing everything down. I actually don't see the need for daily updates. What is causing this and how can I stop it?

I am trying to access the online library website for my college. I had no trouble all week then all of a sudden I keep getting this message: "Unauthorized LTI Launch Request 401

   Please check the configuration settings used for the LTI/OAuth/OpenID access.
   Your browser's "Block 3rd party cookies" or "Prevent cross-site tracking" setting can also cause this error."

I already changed the cookies settings to allow this website and my school's website. I don't understand the issue and why it popped up out of nowhere. I use firefox latest update on Windows 11. I do use a vpn but I used it the whole time, even when the site was working and I have tried turning it off. It doesn't help.

Downloaded an update a few days ago on my W11 OS and FF stopped loading pages Office Depot, Expedia, Amazon it was off and on would show up when it first loaded then when the news pages loaded it would disappear. Tried to use Refresh but it cut off my access to the web message: Secure connection failed...error connection...PR_END_OF_FILE_ERROR. Tried restart with add ons disabled...nothing, tried restart normally...nothing. Any help in this would be appreciated thanks.

Some shades of white have a purple tinge to them. The amazon logo, certain themes, and other websites are slightly purple. This is only an issue in firefox, not any other program or browser.

Even when i set it on start from where i left off, after closing my Mozilla desktop application my all tabs get reset which have been quite problematic for me.

In regards for this, please solve this problem as soon as possible as it keeps hindering with my work

Hi,

Every time I attempt to login to YouTube or Google sites, this site pops up and I'm unable to log in using my personal account. I no longer work at this place and need it removed from my browser. https://launchpad.classlink.com/srcschools?chromebook=1

Thank you for your help in either removing it (if you can) or providing directions on how to remove it myself.

Thank you, again, Kay
