How hard can it be to just ignore it?

a very hateful non-response from stanslausocuru

Hi Can you try adding the following code to your userChrome.css file? If you don't how to do that, just let us know, and we'll show you:

#calendar-tab-button, #task-tab-button { display: none !important; }

I'I don't know how to do that...thanks

Open Notepad, copy and paste the code posted by Chris above into the blank Notepad window then go to the File menu > Save As and type "userChrome.css" as the file name. Include the double quotes, this is important. Save the file in a convenient location, like the Desktop.

Next, find and open your Thunderbird profile folder as explained here Profiles - Where Thunderbird stores your messages and other user data

Inside the Thunderbird profile folder, create a new folder named chrome. Copy the userChrome.css file into this new folder. Exit Thunderbird via its menu and reopen it. When Tbird reopens, the tasks and calendar buttons will not be visible anymore.

that didn't work...I tried twice

It works, but you have to double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Config. editor, under Options/General (at the bottom).

that removed the icons at the top right, but not the "Today Pane" at the botom right

The bottom line is that the information supplied by Mr Ilias did exactly what you asked and nothing more. It removed the two icons from the top of the window.

Thunderbird now has a built in calendar. Like Stans, I would suggest you just ignore the buttons you do not use. Just as I ignore the chat ones. The use of user chrome scripts can to magical things to Thunderbird user interface. It is however technical, and most folks at best, understand it enough to copy and paste. That it needs periodical attention for breakage on updates is a given as this is out of field and certainly out of test parameters. Sure do it if you feel you are capable on managing the process in a years time

All of this ignores the fact that if you have no calendars, then the user interface should not be showing things like the today pane. If you are not using the calendar. That means (calendar properties -> uncheck "switch this calendar on" for any calendars listed in the calendar tab) the user interface should adapt to your choice in the following ways.

NO CHANGE

• "Create a new calendar" link on account central page
• calendar and task buttons in the tabs bar (they may be relocated eventually)

HIDDEN

• today pane
• today pane button in the status bar
• "Events and Tasks" menu

SOME ITEMS HIDDEN, SOME ITEMS VISIBLE AND USABLE

• menu items in "File", "Edit", etc.
• menu items in context menus
• keyboard shortcut keys (some disabled, others still work, following the corresponding menu items)

SPECIAL CASES

• IMIP bar ("this message contains an invitation...")
• Always show this notification to allow users to quickly add the event. If calendar code is disabled, include an option for "don't offer to add any more calendar events".
• Calendar, Tasks, Event, and Task tabs
• Basically unchanged, but if calendar is unused, show a message to explain the current status, and provide a smooth path for users to start using calendar features.

This information is from the implementation bug here https://bugzilla.mozilla.org/show_bug.cgi?id=1617786

I suggest you check that you are not using the calendar as described above, I am guessing you are and do not at this point know it. Once you have confirmed that all calendars are actually not switched on that you post back.

Hi stanlatta, I'll try find you a script to get rid of that. Please give me some time.

despite Matt's incorrect statement ( exactly what you asked and nothing more), here's what I originally requested

i want to remove or turn off the calendar and/or 'events and tasks' in thunderbird 78 "Events and tasks" is showing at the top of Thunderbird; and I asked how to remove or turn it off. I have never used any Thunderbird calendar.

I appreciate Chris Ilias' kind assistance, and repudiate most of you who have hatefully sent unnecesary responses

Disable or delete ALL calendars. It gets rid of those shortcuts.

Final words, for anyone who happens to land on this topic. To hide the Events and Tasks item on the Menu Bar, add this code:

menu[label="Events and Tasks"]
 {
  display: none !important;
}

I find it ridiculous that people seem to assume every one want or tolerate having these bundled features they have no plan of ever using loaded up everytime on their email app. Both this Calendar thing and the useless Chat.

I understand many find the calendar useful, but it should be a simple checkbox option to disable it. That such a checkbox doesn't exists for either "features" both astound and worry me.

Please add the checkboxes to disable/hide them, and these questions/complains will go away.

EDITED: RE: Original question: It's likely you did what I did, and accidentally clicked on the Calendar button at some point in the past. That seem to automatically created a new calendar for you and shows that Event menu.

If you open the Calendar tab again and right click on the one calendar entry > Properties > Enable this calendar, both the menu item and the status item should go away :)

It sounds so simple when demanding for it, doesn't it?

The reality is that there just isn't enough demand for these "simple" checkboxes. Believe it or not, there just aren't that many complains or questions to make this a priority for the developers, especially when there already exists a built-in mechanism for auto-hiding those features when they are not in use, and the solutions presented here.

I am also a developer. I understand that the user's request of any particular app most often far exceed the developers capability to actually do them, and usually take far longer than they expected.

The request is for simple ui addition that should take far less time than integrating new feature into the app in the first place.

I don't need the option to exist asap, but Chat in particular has been in Thunderbird for probably years now, with no improvement or change that I can see, and yet no one has added a proper checkbox for the option that always exist in the config table for the entire time.

More over, I particularly dislike the contributors who tell people "if you want a feature, add it yourself".

Most often times, even developers don't have the time to learn an entirely new platform environments to add a simple feature that should take existing devs half an hour maximum to do, test and commit.

I was hoping you would say that, so that I could request you actually contribute towards achieving this since there aren't as many developers working on Tbird as there are users with their requests, but your answer to that request was thought of quicker than I could.

The request of for simple ui addition that should take far less time than integrating new feature into the app.

Let's assume it is as simple as you claim. What makes you think this simple ui addition is and will be the last of such simple requests? We are talking of millions of users, and most of them have something simple they want added to the ui, so they use the same rationale to advocate for their little wants. If the devs gave in to these requests, I can quickly see Tbird getting cluttered by unnecessary dings and dongs to accomodate wildly varying user conveniences, and we both know it is impossible to please everybody. So, how would a dev decide to grant your little wish over another user's and strike a balance while at it, because there can only be so many checkboxes in the program?

You don't have to like what you're told here by anyone, and that's totally fine. The last thing I want is to try and please you with what you want to hear. Some take it as rudeness, some think it's lack of empathy, but I couldn't really care less beyond the objectivity of such arguments/counter-arguments. For what it's worth, you could actually file a feature/enhancement request here https://bugzilla.mozilla.org/home if none already exists and vote for it and persuade others who also want it to vote for it so that it can reach the devs for their consideration. It's better than being told "add it yourself", isn't it?

If I were a dev on the other end of the feature requests vote list, I would ask, "why should we add this? It's not obstructing anyone's usage of the remaining part of the program."

Stans, please remember that the purpose of this forum is for us to help each other in our use of Thunderbird.

Given that we haven't heard back from the person who asked the original question (stanlatta) in almost 2 months, and this thread has deteriorated into an argument about development, I'm going to lock this thread.
