I have just noticed that the copyright message on the Webvisum website
has been updated. That is indeed an indication that Webvisum is back in
service, but I still cannot find the Webvisum version you mentioned.
Also, the recommendation on the website is to install the latest
Firefox, which is v 64.0.2 as of to date. This is the same version I am
currently using. Please tell us more where from you came by your
information? Many thanks.
