When I launched Thunderbird this morning the right-hand-side panel is completely blank. The left hand side panel shows my folders and if there are any unread emails in them but the right hand side is just completely blank (as per attached image).

Name Thunderbird Version 115.12.1 Build ID 20240618125055

IMAP account on HostGator.

In the last 9 months or so, every once in a while (sometimes several times in a row!) when replying to a message, Thunderbird does not set the \Answered flag on the IMAP server.

I enabled IMAP logging and finally caught this happening. The reply is sent and copied to the Sent folder, as it should, but the original email is never flagged as \Answered.

I can't seem to see a pattern why Thunderbird skips this step, occasionally.

I visted a web site once and left after trying to watch a some movies without any success. Now my firefox are sending notification to my deasktop from this website. But the site is no longer opened in my browser. I tried to to run the antivirus but nothing was found. I checked for any extension and nothing as well. The notification are coming from the firefox itself and I dont know why. And I dont know how to stop it.

Starting a few months ago Tbird suddenly became noticeably slower, and it's only continued/possibly gotten worse, despite several version updates (which I was hoping would fix it). Currently I'm on version is 115.12.1 (64-bit)

I do have several accounts (all pop) and many folders, but nothing different than before the issue began.

I only have 2 add-ons enabled; Remove Duplicate Messages & SmartTemplates. I've of course disabled them and restarted TBird but it didn't help at all.

I've compacted and repaired all folders.

I've created additional folders to reduce the size of larger folders.

The only thing that helped a bit was troubleshoot mode, which definitely made it a bit better going from email to email and folder to folder, and especially with moving emails from one folder to another (which is usually very, very slow and I see it on the bottom saying "moving email 1 of 10 to folder xyz...moving email 2 of 10 to folder xyz...", even if they are simple/small emails). However, sending emails still took over 5 seconds (see screenshot attached), so that might be a separate issue.

In terms of sending emails, whenever I try to send any email it sits on the sending screen for several seconds or more. My internet is fine (2gb fiber, previously 1gb cable), speed tests max out at the 1gb my laptop can handle. Laptop is 2-3 years old high-end Eluktronics, with no other issues.

Given the above, and that troubleshoot mode did seem to help a bit (but straight out turning off add-ons didn't help), what can I try to adjust (while not in troubleshoot mode)?

Thank you very much!

In seeking a way to reduce the CPU & RAM usage, I read that perhaps turning on the Hardware Acceleration might help. And to do that, you must first de-select the default setting which says FF will use the best settings for my computer. Well, when I opened that section, neither one was checked! So, should I first try the default setting, and if that doesn't help, then try HA? I'd always heard not to use HA, for some reason, but I'm ready for trying anything that might help use less resources, and open webpages more consistently.

Which is the best setting to use, or neither one?

Its driving me crazy. When I select a group of Inbox emails, and delete them, it is taking forever. The window will display a "not responding" message, eventually clear that and then the emails are deleted. But it takes way too long. Windows 11, most recent update. Thunderbird, it just updated. I was on a Win 10 computer, same Thunderbird version and deleting took merely a blink to happen.

Win 10 has both VPN AND AV. Win 11 has neither. Help! Thank you,

Hi, the site "https://pixabay.com/" is suddently extremely slow with mozilla. The pictures don't showup or take many minutes before you can see them. Normally only white boxes show. The same site (pixabay) with the browser "Opera" works perfectly. I always use mozilla and since a short while it just doesn't work with pixabay (a site for royalty-free images). Can you please fix it? Thanks. Regards Elisabeth

Have used Thunderbird for 10+ years, as interface to Gmail. Lovely product. 3 days ago I had to reinstall a station but when Thunderbird does its updating after reconnecting to gmail address for the 10GB of emails, it behaves damn irregular: - periodic freezes of mouse and keyboard, for about 0.3 seconds every 3 to 5 seconds. - Thunderbird message says downloading email number out of total number of emails (very slowly advancing) but every 3 seconds it starts downloading email 1 of those emails - station has cumulated some 20 hours working, most of these left to finish syncronizing. Usually in 2 - 3 hours there is time enough.

This happens only when Thunderbird runs, when I close it the station runs fine. Same hardware on the station as before..

Did you encounter this? Thanks.

Mam problem z kontem e-mail. Dotyczy on konta obsługi klienta sklepu internetowego. Od kilku dni maile z Amazon, Allegro, Emag itp w ogóle nie dochodzą. Nie wiem co jest tego powodem, nic w ustawieniach nie było zmieniane, stało się to z dnia na dzień. Jak mogę to naprawić?

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.

I have used Firefox to access my Zoom accoutnfor several years. Today, the screen goes blank when I click on sign-in. This does not happen with other browsers on my PC. Help....

I have had some issues using Firefox and I was told that the website works better with Google Chrome by a support person. For the last recent issue, I was told a website doesn't work correctly basically with Firefox and that I needed to use Google Chrome or Edge. I recently received an email from Mozilla which had a link to an article titled, "Here’s what we’re working on in Firefox" at: link text and in the article in large print it says, "Bringing you the features you’ve been asking for." I didn't see any mention about increasing Firefox's compatibility with websites.

Hopefully, somehow comparability with websites will be made better.

Hello,

All my outgoing messages are bouncing back to me, no matter who I send or reply to, just from one of my email addresses: heidi@benvenutotravel.com

So I cannot reply to anyone nor send, although it shows copies in my sent folder???
