Not sure what you mean by accept https links from thunderbird, but
perhaps it's time that you checked your system overall:

Here is what I'd recommend:

If you have Automatix installed uninstall it. You can reinstall it later
 if you want, but for now get rid of it.

sudo apt-get remove automatix2

Now remove & reinstall ubuntu-desktop:

sudo apt-get remove ubtuntu-desktop
sudo apt-get install ubuntu-desktop

[Note: I have ubuntu-desktop removed on nearly all of my systems but
that is because I install OpenOffice & other software directly. However,
you should remove and reinstall so that you are sure to have all the
proper pieces before going further.]

Now clean up your repository sources:

http://easylinux.info/wiki/Ubuntu_dapper#How_to_add_extra_repositories
Starting at:
sudo cp -p /etc/apt/sources.list /etc/apt/sources.list_backup
Follow the instructions & replace *everything* in your sources list.

Be sure to include:
wget -q http://medibuntu.sos-sts.com/repo/medibuntu-key.gpg -O- | sudo
apt-key add -

Freecontrib.org tends to get hit by DDoS attacks:

If you run Wine:

http://winehq.org/site/download-deb
First, open a terminal window. Then add the repository's key to your
system's list of trusted APT keys by copy and pasting the following:

wget -q http://wine.budgetdedicated.com/apt/387EE263.gpg -O- | sudo
apt-key add -
            ^ don't forget to go to the end "-" mark

For Ubuntu Dapper (6.06):
sudo wget http://wine.budgetdedicated.com/apt/sources.list.d/dapper.list
-O /etc/apt/sources.list.d/winehq.list

Now do

sudo apt-get update

If you get errors, run it again until it runs clean with no errors. If
you still receive errors, then go back to
http://easylinux.info/wiki/Ubuntu_dapper#How_to_add_extra_repositories
and double check your work.

Now do

sudo apt-get upgrade

That will upgrade all of your Dapper packages to the current (as of
today) levels. Don't worry, it won't try to do any upgrades to Edgy or
Feisty etc.

Reboot.

See if that fixes your problem. If nothing else it gives us a starting
point of knowing that you are cleanly up to date & will make
troubleshooting a little easier.
