Thunderbird/Lightning Calendar on Desktop - problem displaying monthly repeating events

Thunderbird Version 152.0 Manjaro KDE Plasma 6.6.5 Kernel 6.18.36-1-MANJARO (64-bit) Graphics Platform Wayland ThinkPad T420

Successfully added monthly-repeating event for the first day of each month beginning at 00:00 hour with duration 0:00. These events correctly appear in another calendar (Google). This also shows there is no confusion between 'monthly' and '4-weekly'.

In Thunderbird's Calendar display, these events do not appear in day, week- and month-view modes, when the first of the month is the first day to be displayed. When the first of the month is positioned further into that view-mode's display then that repeating-event is correctly displayed.

The above happens in Thunderbird's Safe Mode with all add-ons disabled.

Many thanks PS. I am unable to report a bug in Bugzilla due to having lost login-credentials.

I've asked this before to no response. I JUST did a new search and found a users solution that I just tried to no avail. Which was to add the Provider for Google Calendar Extension, then unsubscribe and resubscribe to my Calendars! The old W7 version of the Calendar had the ability to have a Reminder EMAILED to oneself! That option with the new W11 version has disappeared! Can someone please ask the Coders to re include this option! THANK YOU! I 'LIVE" by this option! My Iphone 3rd party Calendar thankfully still has this option! But I would LOVE to have this back on my W11 Laptop in the Thunderbird Calendar!

Something seems to have changed recently with the PDF rendering in Thunderbird. I received an email with a PDF file attached. When I view it on the screen it looks fine, but when printing it out from within Thunderbird part of the top of the first page missing; it looks like part of the image is behind a white rectangle.

When I save the file and print it using Acrobat Reader it renders fine.

I don't know what to make of this behavior, but it does seem to be new and there is a difference between how the file is printed from Thunderbird as opposed to printing using Adobe Reader.

PRELUDE: I have Thunderbird (TB) Version 152.0.1 (64-bit)

I have 45+ email addresses, some at various different domains, 8 (was 10 yesterday) Email accounts with Shaw that was taken over by Rogers. It's been a nightmare. I now have TB working almost as it should, and am use to but, one account has issue.

I tried to format this so it's easy to follow, but more formatting is not available so please see the pictures attached. Pics are self explanatory, but in case, pic 1 shows 3 accounts. The address with issues is the middle address (fake-two (faketwo@there.xy). The other 2, fake-one and fake-three have all their folders.

ANSWERS to possible questions: I used a outside mail to send/receive to/from fake-two. It receives and sends Email.

Yesterday I downloaded 90 emails from my mail server. Only 5 of them were filtered correctly.

Upon reviewing the remaining 85 emails, I observed that many of them "should" have been filtered. So I opened up the Tools - Message Filters and applied the filtering to the INBOX file.

Almost immediately, all 85 emails disappeared. They were not in the Trash folder, nor were they visible in any other folder or mail box that I could see.

It was recommended to apply the "repair" to the INBOX which I tried; However, all that happened was 318 older emails that I have processed a few days before reappeared in the INBOX. Which interestingly would not sort by the date indicated for the email; they would only sort by subject and sender.

It was further recommended to close TB, and delete the INBOX.msf file. Which I did do. In addition, I also restored the INBOX to the previous days file using my daily backup files. That file shows 101,076 kb of info contained in it.

I reopened TB to find once again nothing in the INBOX, and when I tried to re-run the get msgs aspect, the result was the system telling me there were no email messages to collect.

Yet I know the same 90 emails are still sitting in the mail server system.

Why did this happen?

Where did the 85 emails in the INBOX go to?

Why isn't the set of 2200++ email filters not automatically filtering all emails once they are collected, and distributing them to the appropriate email file folder / mail box?

What recommendations are available to help me resolve this situation and prevent it from happening again?

Also, I have a txt and html file of the 8 Jul 2026 filter report. Why can't I upload said files along with this set of information? Why are attachments only restricted to image files?

Thank

Using 153.0b3 and having an issue.

Under Account Settings, I have three entries in the left: Company Yahoo Local Folders

Under Company, my POP3 download/remove from server account I've had since the 90s, under Copies & Folders I have "Place a copy in" for "Sent" Folder on: Company. Same for Message Archives, Drafts, and Templates. Under Yahoo I have "Place a copy in" for "Local Folders" for all four. The ONLY reason I have them set up this way is due to the error message that displays if I try and set any of them to be Yahoo.

I recently went to find an email I'd sent last week using my Company account and couldn't find it. I couldn't find any that had been sent for awhile. I eventually found it under Local Folders(I had "Hide local folders" turned on because I can't understand the reason to it to even exist).

What exactly is going on? Is it a bug with the beta? I'm getting really tired of having to move the messages to the correct folder when all of the settings appear correct(my oldest email is from 1996 btw, so I've been keeping current since Netscape Mail)

I'd like to be able to search for a single email address in TB's inbox. Often I just need to find one email from an email address. I don't need or want to do a "saved search" I just want to reread a specific email from a specific sender. I believe I'm using the classic layout. I've looked through settings, layout, but can't find a way to do that. When I looked through the help articles, etc, all that came up w/saved search. Before one of the latest updates, I could just type in the sender's name or email address, look through all of them, then restore the inbox to list all emails by date. I'd like to be able to restore that function, is there a way to do that?

I have a similar problem to others reporting a connection time-out. But the circumstances now seem different. It is getting worse. First thing today, I noticed that Thunderbird emails (current/up-to-date version) were taking several minutes to finish sending. After sending 3 successfully, but slowly, all further emails failed, as per image attached. My wife's computer, using the same email provider, etc, was working okay. I checked and compared the account setting, and they were slightly different (no idea why) so I altered mine to match the other PC. That didn't make any difference anyway. Then (a few hours later) my wife's PC started having the same problems as mine, as if it's a spreading disease. Could it be a virus? Thanks.

New W11 Pro pc, so new installation of Thunderbird. All profiles and folders moved over ok, but the Bin folder is an issue (main Gmail account IMAP). In my previous Tbird installation, I was able to right click the Bin folder, and be given the option of emptying said folder. Not now. The Spam folder does have the Empty option. Pics illustrate the folder list, what happens when I right click the Bin folder, and what happens when I right click the Spam folder, which does have the 'Empty Spam' option. I can highlight the messages in the Bin folder and delete them that way, but the right click option is shorter, easier... The only item I can find in the Thunderbird help pages tell me to delete the Trash and Trash msf folders in the profile - tried this twice, with no difference. It's a little frustrating... Any help would be welcomed, I guess I'm missing something really simple...
