It's a great new that 2.4 entered beta stage. But...
Beta2 seems broken in certain conditions...
Tested with various browsers, both Windows10 and Wine/Linux (Windows7), with firewall whitelisted and anti-virus software closed:
The default template's action bar and location bar sometimes are not shown. Try enter various pages and refresh them.
Most severe ones are:
View pages with Chrome/Edge, there is a chance that HFS transfers some data, then "die" for a while without responding data. (not sure)
View pages with Firefox/Nightly, HFS only transfers a few data, then "died" too, and never respond any data to any browsers. (this is true)
Switching on/off have no work to them.
Above problems also comes with: not all required files of a page are transferred, thus my index page is broken since no full CSS.
After temporarily resetting options, there's a chance that HFS cannot open any port to switch on.
When I switch back to 2.3, everything is well...
Additionally, It seems that (maybe) these things are there after adopting throwback/takeback templates' initial settings.
Did these only happened to me?
The last thing: How about adding the translation system (.lng file) back
