Banking protection has worked fine with Firefox, but today 1.12.2018 it does not appear in Firefox.
With IE is is fine.
Has there been updates somewhere?
Sorry for my reply. I am only an F-Secure user (their home solutions).
Just as sidenote with another discussions about:
If your experience is still about troublestate - good to doublecheck some things:
-- does F-Secure Browsing Protection addon/plugin is still enabled under Firefox?
-- does something as proxy is used under Firefox?
-- does it possible to check with another banking website (for sure); for example, https://nordea.no?
Just because all working fine with Internet Explorer -> F-Secure side internal trouble is unlikely(?) point; but more likely to check that F-Secure Browsing Protection addon is enabled under Firefox, visited page is under HTTPS and that connection is not 'proxied' by anything. Otherwise - if it is possible - do you able to provide banking website example and Firefox version (and maybe Windows version) for ability to check it with my own experience (I am also only an F-Secure user and with my F-Secure SAFE beta / Windows 7 and Firefox 64bit 63.0.* was all OK today).
There are also some limitations for Banking Protection feature. But (if so) - your experience should be about temporary troublestate OR based on changes by your steps.
