Thunderbird View "Day Starts at:" option not working - Toggling between Inbox and Calendar tabs causes calendar to always scroll back to starting at midnight

I have recently being forced to update to Thunderbird 68.4.2 on my workng machine (and lost access to Rikaichan....but this is the topic for another posting) and noticed that everytime I moved between Inbox or any other tab back to the calendar view last view I had on my calendar was lost!

I was trying to fix this behaviour by going to Tools->Options->Calendar->View->Day starts at:
and then setting the start time to 7am so I could see something like this:

However the view would always be different than that!

I found the following references to this bug here and here but no good fix.

Some of the answer you can find on the first link:

Thanks for reaching out. I think thinks are different in 68.0. The start time refers to when the work day starts (which is time range with different shading). There is no setting view start time.

You're right, there's no setting for the start time - it's midnight. But I note that the scroll bar position in Day or Week view is remembered between TB restarts, so that if the window was scrolled to show 8:00 a.m. at the top at TB exit, it window looks the same when TB is restarted (TB 60 & 69b). Does that at least work on your system?


One of the recommended fixes was to scroll the view as you wanted and then close Thunderbird, so that setting would be saved on session.json but other viewers tried and it did not work.

I think I found the problem, if you made the changes but goes back to any other Thunderbird page (like inbox) before it closes the settings for the view are lost. What I tried and worked for me was set the view on the calendar tab and then close Thunderbird from that view. This has reset the default view to my last one!

I just wish Thunderbird would have this fixed instead of having us need to create work arounds for something so trivial.

Opening an url as a Thunderbird Tab - Web Apps on Thunderbird - Ex. Trello on Thunderbird

I got this idea after searching for years for a replacement to Thunderbrowse. Or WebPG add on.

I then noticed that after installing add-on, some add-ons would open a web-page as a tab and thought that maybe I could modify one of the about.config variables to open a tab with webpages. It did not work!

I then searched for an user based setup I could create to open such a page, on that process I was studying configuration files information found on the page below:
https://www-archive.mozilla.org/support/thunderbird/edit

After a lot of searches I found this page on Content_Tabs:
https://developer.mozilla.org/en-US/docs/Mozilla/Thunderbird/Content_Tabs

I then finally got the ideal below. It is not perfect but it does open  a page choose by user. I wish I was a little more "technically savy" to really know how to improved this but this is how far I went, just follow steps below:



1) First Open Scratchpad on Thunderbird by pressing (Shift-F4)

2) Copy and paste the content below to the bottom of of the scratchpad,
Components.classes['@mozilla.org/appshell/window-mediator;1'].getService(Components.interfaces.nsIWindowMediator).getMostRecentWindow("mail:3pane").document.getElementById("tabmail").openTab("contentTab", {contentPage: "https://tech-me-out.blogspot.com/2020/02/opening-url-as-thunderbird-tab.html"});

3) Click run on the menu of the Scratchpad, it will open this page as a tab in your browser

4) After testing this, you can then replace this part of the line you added: "https://tech-me-out.blogspot.com/2020/02/opening-url-as-thunderbird-tab.html"  by "your own url address" and it will be opened as a tab on your Thunderbird.

As you can see, some web apps like Trello may work too:




I hope it works for you!
