To use the ID-card with Mozilla Firefox, you will need to keep your ID-software updated, so don’t skip versions.
You will also need to use the Firefox extensions Token Signing and PKCS11 loader. If you have problems using the ID-card with Mozilla Firefox (for example, you are unable to access e-services or give digital signatures etc.) the problem is probably in the browser settings.
Our step-by-step instructions will allow you to easily and conveniently verify that Firefox is ready for using the ID-card.
Step 1: open Add-ons
You can do this by clicking on the icon with three lines on the right edge of Mozilla Firefox and selecting “Add-ons and Themes” from the menu.
Step 2: Open add-on solution manager in Mozilla Firefox
There is an option called Extensions, which is marked with a puzzle piece icon in the left-hand menu of the add-ons manager. Click on it and scroll down to the extensions PKCS11 loader and Token Signing, which are marked with the ID icon.
Step 3: Enable the use of extensions
Check that PCS11 loader and Token Signing are not disabled. If necessary, you can enable the extensions by clicking on the slide button on the right side.
If extensions were enabled, you can try disabling extensions, restarting the browser and enabling them again.
Step 4: Check in the browser that the ID-card works
After enabling the use of Token Signing and PCS11 loader, restart your web browser: everything should work!
However, if you’re still having problems when using the ID-card in Firefox, open the browser settings again – this time, disable PCS11 loader and Token Signing first, restart the browser, enable the extensions again and then restart your computer in such a manner that the ID-card reader is constantly connected to the computer and the ID-card is in the reader. After restarting your computer, open DigiDoc4 as the first programme and check that the card details are read correctly. Then try using the ID-card in the Firefox browser again.
