Another here having issues. Firefox 188.8.131.52, running NoScript and AdBlock Plus (persists with both disabled).
Same as reported above: long hang times and unresponsive pages/scripts. Page "loading" animation plays in the tab indefinitely, requires a ctrl+f5 to interrupt.
I wasn't sure what was going on at first since the site has run very slowly for me the entire time I've used it. I just assumed the hosting was a little on the cheap side or something, as it feels a lot like a site getting choked out by bandwidth issues.
