I tried deleting and installing Thunderbird several times but it still requires master password that I wrote when I installed StartupMaster add-on on my Thunderbird. I don't know what to do because it seems like I won't be able to install and use Thunderbird on my Mac any more? I thought that maybe there is a need to delete Thunderbird completely from my Mac but I don't know how else I can do it - I just delete the Thunderbird like I delete all other apps. Thanks for help.

that's the problem - when I open thunderbird there is not tools shown in menu bar, basically there is almost no menu bar, see screenshot.

Besides, I installed StartupMaster Add On for master password, maybe it's because of that?

It worked, thank you so much!

As a mac user and therefore a small minority user I suggest you learn now that References on the web to Tools > options is for windows. On a mac that is Thunderbird > preferences. Once you learn that small thing lots of previously opaque instructions become crystal clear.
