The new version of the Firefox browser may cause issues in using ID cards on shared computers

The new version 90 of the Firefox browser will be published this summer. The tests conducted by the Information System Authority (RIA) show that this version will have issues in computers running the Windows operation system if several different ID cards are used for logging into e-services.

The RIA has tested the ID software with various different beta versions of Firefox. At this point, it is not possible to use several different ID cards for logging into e-services on a computer which is running the Windows operation system without emptying the certificate storage. Logging into e-services fails, as the new Firefox version remembers the certificate of the ID card which was used last.

For authentication by an ID card in the Firefox browser on a shared computer (i.e. to prevent the browser from remembering the previous selection), the certificate storage on the computer must first be emptied or automatic removal of the certificates must be selected upon installation of the software (see the instructions »).

The new version of Firefox is scheduled to be published on 13 July.
