The reminders window that normally starts up when Thunderbird opens no longer appears. To be clear it's the window that shows my daily appointments in a separate window. Thanks

I cleaned the AppData folder to speed up the computer, then it turned out that there were Mozilla files, which threw away all my data form browser. I synced the browser data on the phone, but it didn't transfer everything (history and login data missing). What to do to have my passwords again on the computer?

When using the new version of Firefox, I found that bookmarks only appeared in new tabs. Once I opened other web pages, there were no bookmarks above the screen, which made me feel inconvenient. Previously, the new tabs could also be customized, but now they can only be blank or the default pages of Firefox. So, can the new version of Firefox solve these problems? Or which of the older versions of Firefox can still meet my requirements?

After accidental change to Thunderbird 140.0.1esr (64-bit) all date/time display changed to American format (7/16/2025, 12:55 PM) where it used to be the settings of my machine (Win10 64 bit, language English, region Netherlands): short date dd-MM-yyyy long date ddddd dd-MM-yyyy short time HH:mm long time HH:mm:ss I tried overriding the setting using the config editor and inserted ntl.date_time.pattern_override.date_short and ntl.date_time.pattern_override.time_short, restarted TB which promptly lost the new settings (not saved). Also the Message List Display Options defaults to Cards view after restart, even after changing to Table view.

Please help!

Every time I make Firefox full-screen, it immediately crashes and shuts down. I have restarted the computer, uninstalled and reinstalled Firefox, but it still doesn't work.

I have tried to add this address to my address book. Normally, one clicks on the icon and a pop-up appears to modify information and confirm entry into address book. This address always shows up as "not in book," clicking has no apparent effect, until one checks the address book and now duplicates exist.

First image you can see that Freeman is in the address book Second image you can see that Tbird thinks the address is not in the book Third image after I've clicked and no apparent action is taken, a duplicate appears.

When this bug first appeared I had clicked on the icon multiple times, and multiple entries appeared in address book. I deleted them all, tried again, bug still happens.

Hello, I manage a healthcare education website (https://thelabon.com/contact-us/) and I'm focused on optimizing privacy and performance for users accessing our medical content through Firefox. Currently I have not embedded it yet I am using only an image of the map instead. What are the recommended Firefox settings, extensions, or practices to ensure user privacy, especially when embedding external tools like Google Maps or analytics services? Any guidance would be appreciated!

TB New V140 has an issue: when adding a new email account the wizard stays in a loop, no information why and no option any more to add the account data manually. No idea why it's necessary to keep users out from a manual setup and let them use a not working apple style wizard....

Context: Windows 11 23H2, Thunderbird Portable (102.15.1, stubbornly declining updates until the Supernova IU starts looking tolerable), Avast Antivirus. Multiple email accounts on various servers, all POP3.

For the last several months (not sure when it started, but I first took a screenshot in October 2024, so perhaps that was the first time), after each time I reboot my PC, the first time I send an email using one particular account will trigger a complaint about a bad certificate, which is probably caused by Avast getting in the middle of the process. Clicking "View..." opens a tab with certificate information. I'm attaching screenshots.

I assume my other accounts also had a similar complaint when they were first used, but it has been a long time since I added a new account and they are all quiet now. But on this account, I get it the first time I send mail (normally a reply to someone else - this is not my default account for new messages) after each reboot. When I click "Confirm Security Exception" with the "Permanently store this exception" checkbox checked, the next thing I get is "Send Message Error" (see the third screenshot), then I click OK, and then I can hit "Send" again and the message is sent with no complaints. Then I can also send future messages with no complaints until the next time I reboot. (I don't reboot often - normally just when Windows needs to do an update.) This is the only account on Dreamhost (others are InMotion or Google), but other than that, there is nothing special about it, as far as I know. Why is it forgetting my "permanent" exception? Is there a setting somewhere that I should look for?

I just now tried following the instructions on this page: https://support.avast.com/en-us/article/troubleshoot-invalid-antivirus-email-certificate But it says, "This certificate is already installed as a certificate authority." Perhaps that is because I have already gone through the process for this reboot cycle, but if TB needs a new Avast certificate or exception each time I reboot (due to something changing in Avast, perhaps), I'd think the first email I send through any server would ask for the exception, but it's never any other account - just this one Dreamhost one. Fortunately it's just an inconvenience, not a showstopping problem, but it would be nice to solve it eventually.

I can’t see or search for the hundreds of bookmarks I have in the mobile iOS version but have no problem on a laptop. Can’t seem to find an answer anywhere. Tried * and # as I ve found suggested elsewhere. Seems like something that shouldn’t be this hard

Hello. Since calendar category colorization is not very visible ...

... I created separate calendars for every category. This is semantically wrong but has a nice look – events are fully colored by category:

I now regret this choice and want to correct it:

I need to move >1000 calendar events from calendar "medical" to my "home" calendar and (at one go) assign the category "medical":

from [calendar: "medical" / category: none] --> to [calendar: "home" / category: "medical"]

How can I do this ?

(note: I don't know why the screenshots are not displayed in this message.)

Muy problem is ony desktop.. A few days ago I started having the problem that when I click on a link, a new tab opens but it does not load any content. The little dots on the tab go back and forth but nothing loads. My home page always opens and I can open articles on that page, but new links do not open. I restarted the computer and it seemed that the problem had corrected, and I was able to open a couple of links but then nothing more would open.
