A similar problem arose recently where the Import dialogue was missing buttons for some options and the buttons were clipped for others. The problem turned out to be due to the user installing TB as part of the SoftMaker office suite. Did you download the installer from the official source?

In any case, I recommend you uninstall TB and run the installer; this will not affect your profile folder containing mail, contacts etc.

Thanks, but is not the situation. I've the two situations, fresh instalation and update situation. Always from the Offcial source.

Try running in safe mode (hold Shift (Mac:Option) when you launch TB), as this applies a default configuration, among other factors, for windows and controls that might indicate yours is broken.

Hello, Even in safe mode doesn`t work. I Think is a bug form this latest version on the Portuguese localization. Like I told, it´s a fresh installation and a update installation, on diferente machines. All running Mac OS 12.12 (Sierra)

A while ago, there was a similar issue with the Options/Preferences window on a Mac.

It is as if your computer font /dpi is too large for the preset window size and so looks like it is clipped.

Have you tried increasing/decreasing the dpi settings on computer to see the effects in Thunderbird Import window?

Possible workaround: The import window is not a window generally used very often, so try the change in computer resolution dpi settings to see if you can that 'Import' window to be good enough with buttons, so you can at least use it. You can always reset dpi resolution afterwards if required.

Please report back on whether this works and what dpi settings helped.

Toad-Hall, I`ve already tried monitor resolutions, but without any positive result.

I insist this situation is a Bug on this version.

I`ve instaled the previous version, works OK, I imported the contacts and update to the last version. The contacts are already there but it´s not possible to import again

If you were to install TB 52 in a localization that doesn't have buttons missing, e.g. EN-US, and then install the Portuguese language pack in that version, would the end result be correct?

I agree, On 4/25/17 late PM I received a message from Google and they advised someone tried to log in on my acct, so I should change my password.. After that I opened TB & I couldn’t even get any new mail to download. I could open TB but read only previous downloaded mail not send any out. Now my spouse & I use Profile Manager & her g mail email acct works perfectly so my TB program on my pc is not the problem.

This happened because I responded as Google suggested & now I have several days into this. I can now get new downloaded mail, this all started why I don’t know after I opened Tb & it asked for my password & I inputted the new password which did not work several times prior so why now? But I couldn't and still cant send any emails.
