Suddenly cannot send email through Zimbra using Firefox--Google Chrome works fine. This started on 5/22
I use Zimbra to access my email. It has always worked fine in Firefox, but suddenly on 5/22, and to the present, I can receive email but can't send or forward. It works fine with Google Chrome. I would like to keep using Firefox. Any suggestions?

Please explain the problem in detail. What happens? What is the exact error messages?
The problem is that when I try to send or forward email via Zimbra through Firefox, I get screen that looks like it is trying to load. Spinning blue dots. It works through Google Chrome.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?
While you are in 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.
How to disable Hardware Acceleration {web link}
If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.
- make sure your extensions and filters are updated to the latest version

Firefox shows the shield icon at the left end of the location/address bar in case Content Blocking is blocking content.
- click the shield icon for more details and possibly disable the protection
You can check the Web Console about what content is blocked
- "3-bar" menu button or Tools -> Web Developer

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Safe Mode start window
