I have a wide screen and wish to centralise the calendar Task Buttons on the calender toolbar. I have places 'spaces' in front of the buttons but they are not retained when closing/opening Thunderbird. The mail toolbar retains the 'spaces' ???

In the attached picture, I selected View/Toolbars/Customize... in the Calendar tab, dragged the Event and Task buttons to be the right-most buttons, then dragged Flexible Space from the Customize window to the left of the Event button. This layout is retained between TB restarts.

Maybe you have to start in safe mode (hold Shift when you launch TB), check 'Reset toolbars and controls' and click 'Make changes and restart'. This will reset your custom toolbar settings, but may keep a custom layout retained between restarts.

No, this did not work.

My result is with TB 68.1.2 32-bit/Lightning 68.1.2 on W10. What is your version, and do you have any other add-ons?

TB 68.1.2 32-bit/Lightning 68.0 on W10

Additional Add-0ns: Configdate Provider for Google Calendar

I don't know if it makes a difference, but I would try this reset procedure to get the correct version of Lightning, 68.1.2. Also, I don't think the Provider add-on causes toolbar issues, but try disabling it and see if that has any effect.

Thank you for your help but this is not going anywhere.

My Thunderbird 32bit version 68.1.2 will not update lightning 68.0 to 68.1.2?

I have also downloaded a new version of Thunderbird 68.1.2 which has lightning 68.1.2 intergrated. I still have the same problem with the calendar toolbar.

I would like the lightning team to look at this problen for both the of the Thunderbird versions.

selected View/Toolbars/Customize... in the Calendar tab, dragged the Event and Task buttons to be the right-most buttons, then dragged Flexible Space from the Customize window to the left of the Event button. Upon restarting Thunderbird these settings were lost.

I can reproduce this in 68.1.1

Set up again and then selected to update to 68.1.2 Upon restart to enable the update, it opened on calendar tab and all looked correct and centralised. Restarted Thunderbird and all is back to the default.

I can reproduce this in 68.2.1

Note Lightning is correct version in both versions of Thunderbird.

So I am seeing same issue.

Really weird stuff going on here!

Calendar toolbar looked like default. Disabled Provider for Google Calendar upon restart Calendar tab now shows the Event and Tasks centralised. Exit and Start Thunderbird and all back to default setting appear lost.

So I enabled Provider for Google Calendar addon and clicked on restart. upon restart to enable addon, Calendar tab now shows the Event and Tasks centralised like magic. Exit and Start Thunderbird and all back to default, toolbar setting appear lost.

So the settings seem to be saved and reappear if either disabling or enabling 'Provider for Google Calendar', but not when exit and start.

Toad-Hall, thank you for your posting

I have been using Thunderbird and Lightning for some time and found it great for handling my mail and calendar requirements.

However, I wish they would look at Firefox and perhaps try and provide the same customisation. In Firefox I can centralise everything including the Tabs.

Checked: xulstore.json file - relevant section shows the 'centralised' edited layout even though it is not displaying.....interesting!

...,"calendar-toolbox":{"mode":"full"},"calendar-toolbar2":{"currentset":"calendar-synchronize-button,calendar-edit-button,calendar-delete-button,spring,calendar-newevent-button,calendar-newtask-button,spring,calendar-appmenu-button"}

sfhowes: any ideas on what could be over riding the xulstore.json file ?

Located a bug report, so you can follow it: https://bugzilla.mozilla.org/show_bug.cgi?id=1582888

I don't know what could be overriding xulstore.json, but I repeated the test and got the same results: the Event and Task buttons are in the centre, and this arrangement is preserved between TB restarts. I do not use the Provider add-on. Here is a section of the json file:

calendar-toolbox":{"mode":"full","labelalign":"end","iconsize":"small"},"calendar-toolbar2":{"currentset":"calendar-synchronize-button,calendar-edit-button,calendar-delete-button,spring,calendar-newevent-button,calendar-newtask-button,spring,calendar-appmenu-button","mode":"full","iconsize":"small"}

Note the differences with the content posted before. This is with a profile that was upgraded from TB 60 to TB 68. So, I tested with a new profile created in TB 68, and found that the calendar button layout is not preserved between TB restarts. I guess profiles created by TB 68 (and 70b3) don't handle the calendar layout correctly.

Thank you both for your help.
