Browser Support • Re: Pale Moon response speed under miserable ping times

Real-time feedback typing into dialog boxes, like this one, is highly flaky

But the forum's post input boxes do not provide real-time feedback by contacting the server (on keypress or what not) unlike some "modern media" sites that literally want to track your typing behaviour. So if it responds sluggishly, then that is because of something else (locally), not networking. Providing us with the full troubleshooting information as asked in the template would likely help.

Go to Help -> Troubleshooting information... and use the copy-to-clipboard button on top of that page to copy the text, then paste in your reply.
