In addition to "James" suggestion of removing all plugins. Except for the Adobe Plugin, try adding back what you originally had one at a time.
If adding a particular plugin causes a Crash or an odd operation or action, remove and add the next. If you find a particular plugin that doesn't work right, see if you can another that does the same chore.
As far as the Adobe Plugin, go to Adobe's website look for the plugin and download the very latest version. The issue with the Adobe plugin was only an issue the certain older versions of Office. If you have been keeping up to date (version 15.35 or better),
you should not have that issue. When Office was switch over to 64-bit, Adobe forgot to create and send a 64-bit. In Apple Computer the OS is 64-bit. Unlike Windows, the Mac can not tolerate 32-bit plugin and extensions. On windows. They work fine the just
slows things down. On Mac 32-Bit extension can cause system crashes Kernal Panics, odd operations of the OS or application they are associated. In other words, there is no tolerance for 32-bit on a 64-bit System or Application.
