Thunderbird Portable

For several weeks, incoming emails in Thunderbird are not displayed correctly because special characters in Spanish are not recognized. The outgoing emails, on the other hand, do read well on my PC.
I have made a new installation of Thunderbird without adding my profile and only configuring the email account and the problem is the same.
The version of Thunderbird that I use is 60.6.1 for Windows Spanish (from Spain) with MD5 24f19cdee7a0ba3e0791f508753b11a7 and I have tested it in Windows 10 of 32 and 64 bits with the same result.

I'm a long time user of SeaMonkey and have recently started to have problems with sent messages not being copied to the selected Sent folder.

I recently set up Thunderbird Portable and attempted to import the emails from my SM folder, but totally impossible to do, from what I see. My SM folder has a separate folder named Mail, but I cannot find one in my Thunderbird folder. I figured I could copy the appropriate folders and files and it would probably work, but I can't find them to even attempt this.

Something I've noticed over the past couple years is that TBP seems to be really struggling with write performance to my 32GB USB 3.0 flash drive.The one I have is a "Micro Center" branded drive. The USBDeview utility says it's a Kingston flash drive under the covers.

TB is following a common method of updating the software which is that it automatically identifies the availability of updates and then urges the user to perform the update. At least that is how mine has been set up. Portable apps has its' own method of identifying available updates and then urging the user to perform the update. Do these different methods conflict with each other. Is one or the other invalid or maybe we should say NOT applicable?

Considering changing from installed version of TB to a portable version. Can the profile from my installed and running instance of TB be moved to the portable version. If so how? Does the profile manager function properly on the portable version? If so how is it invoked?

I am a long-time user of SeaMonkey. I migrated when Netscape Navigator went under. I understand that the SM Mail interface is TB based. I also have vision issues and sometimes miss 'small but significant' options.

I'm having email download problems from my ISP and the response on the SM Mozillazine forum was to try ThunderbirdPortable to see if it could pull in mail.

One responder suggested I download Mozilla Thunderbird, Portable Edition 52.8.0. Somehow I ended up with the more recent version.

Hello,

Thanks

I installed the portable plugin to ThunderbirdPortable\App\gpg. But TB 60.5 always requests to Install GnuPG since Enigmail states that it is NOT INSTALLED? But it is.

What am i doing wrong??

When I updated to TB 52.8 it kept some extra toolbar buttons from an old extension Toolbar Buttons that worked great, but wishing to add Copy/Paste I installed it again. Not only I did not get the new buttons, I lost the ones I had like Select All, Undo Redo Reset, Empty Trash, Not Junk etc. I find them crucial so I'll have to revert to an old TB version if I can't get them back. Starting with extensions disabled did not bring them back even after removing the newly downloaded Toolbar Buttons. Is there a Restore function for TB or a way to revert to a previous profile?
