• Does Thunderbird work in TB Safe mode (see Thunderbird Safe Mode)?

Thank you for you help.

TB now seems to work with the newly added 'POP' account.

However; the screen/window of the newer version of TB is a lot 'busier' than the old version. I have used the various available OPTIONS and TOOLBAR CUSTOMIZATIONS to get rid of some of the clutter, but I cannot seem to find a way to make top-most screen bar display simply the program name and the traditional Windows 3 buttons in the upper right corner (and not have them included in the menu bar) --at my age I am a traditionalist and still prefer to original Windows frame.

I would also prefer to have the TABS below the ToolBar. Some years ago I found an Add-On for Firefox (Classic Theme Restorer) to achieve that arrangement, but cannot seem to find one for TB. Any help you can provide would be appreciated.

It seems to me that "tabs on top" is more logical. Tabs can hold different types of content (though at present in Thunderbird this is pretty much limited to email reading or calendar; in the future tabs might be used for address book and message composition.) However, calendar and email, rightly, each have their own toolbars. A mail toolbar could offer actions which are not appropriate in a calendar, and vice versa. Hence a toolbar within the tab and attuned to the tab's function seems right, to me.

If you never use Thunderbird for anything other than mail (some use it for RSS feeds, newsreading, chat, calendar etc), or if you are a heavy user of the smaller toolbar in the email message window and therefore don't rely much on the main toolbar, then maybe this won't be of concern to you.

There is a "rise of the tools" add-on which seeks to reposition the toolbar on top.
