Hi skibum8668, sorry to hear the upgrade was so disruptive for you. There tend to be a lot of differences among users' computers, so rather than try to address thousands of users in one thread, let's talk about your computer.

Extreme Slowness and Freezes

First, please rule out the bug related to Accessibility Services. That is covered in the reply from philipp in the following thread: Firefox 57 hangs up.

We also have general support articles with tips that might be useful:

High Memory Use

Firefox has been a multiprocess application since around Firefox 49. Firefox 54 was the first version that used four content processes, but for many users, Legacy extensions were preventing the full expression of this feature. Therefore, some issues may just be picked up now.

If you want to experiment with reducing the number of content processes, the settings are outlined in this article: Firefox's performance settings.

We also have a general support article on memory use: Firefox uses too much memory or CPU resources - How to fix.

Other Issues

... it freezes, its very very slow, it errors, its using 5 to 6 firefox.exe processes which is draining all of our physical memory.

What are the errors?

we need to be able to uninstall it and go back to the previous version and then wait until the next new version, just not quantum.

There is an article on that, too: Install an older version of Firefox.
