I still have problems (to logon) using Chrome, not with FireFox (it may depend on browsers' extensions).
FSH is not working properly now in FireFox (and it really helped me a lot)
cheers

Thanks for bringing this to our attention. The team is looking into the cause of this. Hopefully this will be resolved soon. At present, the known browsers impacted include Brave, Edge, and Chrome. The website will still load through Firefox.
