Thunderbird Support Forum

Could you please assist for that issue: I've updated 91.latest Thunderbird to 102.1.2 and all tasks disappear? I can't make return to previous version of thunderbird 91 where is lightning work properly. However, I made buck up copy of my calendar and I can see all tasks in file, but it's not appeared in version 102.

I have 10 calendars to sync and all but 2 are from different sources. myical.ics and Hawks.ics are from the same source (a folder on my web site). Hawks.ics works fine, as do the other 8, but myical.ics does not display (so I don't know if it syncs or not). myical.ics syncs perfectly in google calendar I tried a new profile but the problem remains the same. I have reverted to ver 91.12 and it works okay (as it has for many years). Is this a known problem ? If not, some assistance would be appreciated as I will not update to 102 until it is fixed.

Thank you

Since updating Thunderbird to 102, I can no loger import the lightening calendar. Exporting a .ics file from one pc works but on trying to import it into any other pc or the same one, I get "No importable items found in the file". Any help would be appreciated.

I'm migrating to a new computer and from Windows 10 to W11. I have successfully exported/imported the contacts using the export tool, but cannot figure out how to ex/im the calendar. I am using a SanDisk drive to move the files. Both systems have TBird 102.1.2 (64-bit).

Please give step-by-step instructions to do the calendar (only) ex/im. I do not use the Mail feature.

Using Thunderbird v102.1.2 Platform: iMac running Mojave 10.14.6 email: [edited from public] @earthlink.net

Unable to link to an Apple Mail account (on iCloud). Tried every solution on the web and still nothing happens when I complete the new calendar form (which seems to be different from many of the examples on the web}. Using the same information and entering it into my older Sunbird account, it links up immediately.

This seems like a simple problem, and I am willing to settle for a read-only sync, but after numerous hours of research and attempts, nothing works.

I am apparently doing something wrong in Thunderbird/Lightning. Please advise your thoughts.

Thank you

It's not on settings. I found this css code but don't know how one installs css for thunderbird. I got as far as opening the config editor on the calendar options. But I don't see what entry it is.

Alternatively if I can change the weekend colors that would work well. They are nearly the same yellow as the CURRENT color.

Just a couple of days ago, Google calendar no longer syncs with Thunderbird. I didn't change any settings and it looks like I can't even re-add the Google calendar events it should sync to.

When I install Thunderbird 102.1.2. (64) on my Windows 10 PC and install a calender (via net) with a link to my Synology DS220j NAS. Thunderbird shows a turning wheel for hours. In the task manager the "inbox" seems not to run. From then on, I get always the turning wheel when I start TB. I could stopp this by deleting the directory "calender-data" in preferencies and delete the Synology-Calender in TB afterwards. I see this behavior on 2 PCs. The Synology Caldav works fine with Outlook and some Androids. Has/had anyone the same issue and a solution how to manage it?

It's a pity that we reached version 102.1.2 and till now a common problem has not been solved. In email composing window when misstype a word there is the red indicator for mistakes and then by right clicking we get the correct proposed words. In event creation we get only the red indicator for mistakes. Nothing more. It's a pity a so much advertised version to lack such a basic feauture.

Thunderbird recently prompted me that an update was available to v 102.1.2 (although the release notes say it can't be installed this way yet). Not sure which version I had before, but probably the last before 102 as I update when prompted. I wasn't paying enough attention, of course I should have realised it was a major upgrade and backed up my data first ...

Email seems fine but I now can't see some calendar events, depending on the view: Day and Week show no events at all, Multiweek and Month show up to and including 4 Sep 22. I can't see any events beyond 4 September, although there is a multiday event that start on 2 Sep - it's not visible in the calendar after 4 Sep but the details still show the end date as 11 Sep.

Some recurring events have disappeared completely, but one on 31 Aug is visible in Multiweek but not in Month view. So maybe the events are still there but not being displayed?

I had been using the "Calendar Tweaks" add-on, which is no longer supported, so I removed that and restarted Thunderbird, but it had no effect. I also see that there have been a few issues like this with earlier upgrades, but none of the fixes seem to match the current state of things. Would really appreciate it if anyone knows how to fix this.

I have followed all of the instructions by Toad-Hall (as far as I know ) for making categories in my calendar different colors (instead of the small bar at the right).

I have made sure that the legacy is not false I have opened Profile, added folder called chrome, copied the text given into folder called userChrome.css (this was saved as txt, which I changed to css).

I then started Thunderbird and still find that I cannot get full color in my events.

What have I done incorrectly? (I am on a Mac running Big Sur). Thunderbird version is 91.12.0

Thank you for any help.

Referring to this archived post, https://support.mozilla.org/en-US/questions/1304213.

I have the same problem - very difficult to find "TODAY" on my calendar. Mozilla - may I suggest highligh of "Today" as an option people can easily set in Calendar settings?

Post reply provides info on changing the userChrome.css, then says to

"Toggle toolkit.legacyUserProfileCustomizations.stylesheets to true in Config. editor"

How/where do I toggle this? Using TB 91.11.0

Thanks, Greg

With the update to release 91.13.0 the icon to open the calendar disappeared from the tool bar. The icon is now located above the search box. How do I get it back to where it belongs?

Where can I find the meanings of the symbols on an event in Thunderbird calendar? I have some events that show a wrench, and for these events it seems I cannot dismiss reminders. And how do I get rid of it?

Thank you in advance, Stephan

This morning when I opened Thunderbird all entries that have other participants invited have disappeared. The entries without other participants are still there. I am not aware of an update. I can create new events and invite people. It seems the data is just gone somehow, and I somehow need it back.

OS: Ubuntu 22.04 Thunderbird: 91.11.0 (64-bit) How to reproduce: no idea

Why don't you incorporate the fabulous code from Calendar Tweaks by DW-dev. This add-on made the calendar much more useful. Since it is no longer being supported, it should not be a problem. The current little color tags on events is lame.

Hi,

I noticed when dismissing any and all calendar event with Thunderbird I'm always presented with a "Item Changed on Server" dialog.

It asks me to "Submit my changes anyway" (even though I've made no changes) or to "Discard my changes and reload"

It doesn't occur on any other app that I use to receive calendar notifications, it should just dismiss when I click dismiss from the initial alert.

Is there something I've missed in the set up or a work around to prevent this dialogue to pop up when I "dismiss" a calendar notification?

Any help would be greatly appreciated.

Hi guys.

I have a small problem that I'm trying to solve. I'm in Linux, but unfortunately, I still have to work with MS outlook, in VMWare, because Thunderbird have a lack of functionalities comparing to MS outlook, and I cannot live without these functionalities. I manage over 100 complex calendar notes per day, with attachments (e-mail attached, images, and other calendar notes attached).

The following functions could increase the functionality of thunderbird if they were implemented: - Select several notes at the same time, to delete them, or to Drag and drop to another hour or another day, just by releasing the notes in the day using the side calendar (that has the number of the days) or releasing the notes on the day visualizer; - Select several non contiguous days using the function key CTRL (example, day 3, 8 and 15), to view them side by side, and/or to drag and drop calendar notes from one day to another; - Ability to add attachments to calendar notes.

I'm really looking for a management of the calendar, similar to Microsoft Outlook, but I don't want Microsoft, I want open source.

Do you guys know if there are plans to implement these functions in any near future?

Thanks in advance.

Ever since the release of Thunderbird 101 (and subsequent updates) my calendar has been missing events and today I decided to delete my old calendar and start my calendar from scratch. After hours of painstaking data entry today I entered an event that I wanted to repeat on the last day of every month. Low and behold the event didn't record, so I entered again and it did record but when I moved to the next month and returned to the current month the event had disappeared. Not only that, other events that I'd recorded previously started to disappear. The calendar has been a crock of s**t since the upgrade and I'm now seriously thinking of dumping Firefox and Thunderbird rather than waste any more time trying to work out why my calendar, which worked perfectly well before the upgrade has ceased to function in any useful manner. I've asked before without any response. Doesn't anybody else use the calendar? Does any body know what the f**k is going on?
