Thunderbird does not open. A fine 50cm line can be seen on the screen which can be moved around but not enlarged. New email notification still appears to be working but there is no thunderbird interface to view the emails. Windows 8 computer.

One feature at www.weather.com (Weather Channel) is their "weather in motion" feature which loads interactive weather radars. For some reason, this is not working on my Firefox browser. It works fine in Chrome and Edge. The weather.com website loads just fine but the radar data (overlay on a map) will not load. IT WORKS FINE IN SAFE MODE. So i tried to disable all of my plug-in's, extensions and hardware acceleration in Firefox in regular mode. Still doesn't work. I created a new profile. Still doesn't work. I disabled the tracker feature in Firefox on that web page. Still doesn't work. I uninstalled and reinstalled Adobe Flash. Still doesn't work. Any ideas???

Firefox version 82.0 64 bit Running Windows 10 Professional

My issue is the lack of a heads-up from Mozilla Thunderbird about the downside to upgrading (I use the term loosely) from 68 to 78. Where was the warning that the add-ons I was using would not work (and now, months later that there are STILL NO UPDATES to v78-compatible add-ons). I was not aware that there were profile and database changes that would occur making for problems for lots of users.

The forum is full of comments about these points so I'm not going to belabor with further feedback but I would like to emphasize that Thunderbird may very well have signed it's own obsolesence warrant for failing to take its customers base real needs into account. Fortunately for me a roll-back to 68 was easy since I had just done a full image backup.

I'm not really looking for "help" or a solution to a particular problem. But, respectfully, WTH were you thinking?

After updating Mozilla Thunderbird to version 78, the connection to the mail server was lost, IMAP error the selected authentication method is not suitable, how and what exactly should be fixed on the server if everything works on the previous version

Hi: I've just by mistake downloaded the Thunderbird Update from Ver 68 to 78 and I want to go back to the Version 68 - could you provide me with the details how to do it, please? Your earlier advice would be greatly appreciated ...! Many thanks. Tony H.

Having used Thunderbird for many years, today I can't send mail, and recieved the attached message.

My ISP offers an online mail option, and on that I CAN receive email, but I want to continue to use Thunderbird as I've used it for a long time, and have filed all of my archived emails.

Apparently, my SMTP settings are incorrect, but I've tried everything. I've also turned off my Norton Firewall and anti-virus, but still the same issue.

I can receive mail, but I just can't send.

SMTP settings also attached.

I am running Windows 10 and Thunderbird 68.11.0 32-bit.

Thanks.

So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

As written in the subject, in the 78.4 version when selecting "Edit as New Message" the "To" field is not accessible. Is this a bug or a feature? In the latter case I would say it is less than ideal as at times it might be useful to modify the list of recipients. Thanks in advance for any help/clarification.

I recently installed a fresh version of Thunderbird and all went well. Then I changed my gmail password (because it was old) and now Thunderbird does not prompt for my password. I get a Google dialog (in the Thunderbird browser) asking for my email but when I enter that and press next I am asked again for my email. I never get to my password and so I can't enter it for Thunderbird and now I can't use it to read any emails.

Something is not working but I can't tell what other than it seems to be on the Thunderbird side.

Hi all,

When I open a pdf in FF, it does not remember my settings, even though I have set to always open in Adobe Reader. I am running the latest version of FF and Win 10. I have recreated the handler.json file.

Regards,

Steve

I followed the steps backup the Thunderbird profile and copy to the new computer. When started the Thunderbird, it requested me to login with my existing email, then only a small portion of emails in In Box showed, all subfolders disappeared. Can someone help?

Greetings from a dummy. Naturally I do not use Microsoft Outlook yet I have just received some emails from a known person these emails had attachments attached but they were in winmail.dat form so naturally were unable to open spoke to sender and he resent but no change. Any help will be gratefully received Geoff

I was watching YouTube today and i realized a flashing white line in the bottom left of my screen. then i went to a few different website and i saw the same thing, although the position was different. I realized that the position of the line depended on where you clicked and only on lines of text. i haven't downloaded any add on in a wile and i have only just saw this today.

Before i never had this problem but heres it is. For a while i had a issue on Firefox not showing thumbnails. I restarted firefox and it fixed it till it updated and the issue reoccurred. I figured out that if i kept webp enabled i can see my thumbnails but now i cant download gifs as gif files but webp files. Webp files dont work for what they are used for. Ive tried shuffling the webp permissions but nothing is working. Is there any way i can have thumbnails show and also not download as webp?

I use Thunderbird to download my e-mails from three domains. - yahoo.com.au - russell.im - anglosunshine.com

The latter two are hosted by Marcaria.com

After migrating to version 78 of Thunderbird, I had to re-authenticate with Yahoo - which was successful - to continue downloading my e-mail, but e-mails from russell.im and anglosunshine.com ceased. No error is thrown up. I tried: - removing the password - to prompt for new password to be entered. No prompt. - turning off my Nortons firewall - no effect - setting up new account - to check the server settings. Server settings identical.

I can view the e-mails by a web client (from Marcaria.com).

the problem seems to be linked to Thunderbird. Any help please?
