Each and every time I try to reply to an email received in my Optimum Online account, when sending there is a pop-up (drop down) saying "Webtop error" and nothing else. There is no record of this error in the Mozilla database. I have found little if anything elsewhere. Email can only be replied to by using a different browser, such as Opera. Windows 10 x64. All latest software updates installed.

Upon further search, I find that "webtop error" may be related to Unified Compliance Framework, which sounds Draconian. Further research is proceeding.

If there is still a problem,

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

While you are in Troubleshoot(Safe) mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.
