To make is so there is no need to download files i took screen shots and uploaded them to screencast This one is before i uninstalled and i ever removed registry keys rebooted computer Win 10. https://www.screencast.com/t/ufygVNJaxIb

This one is after the reinstall and it still said it looks like i reinstalled. https://www.screencast.com/t/ufygVNJaxIb

Firefox with one tab open to the default home page right now as i type this and the memory usage it over 300 Mb if i open another tab the memory usage will go up another 100 to 150 mb. Does not matter what site as it can be just google.com at the same time 3 tabs open in chrome and memory usage is around 324 MB.

I have turn the performance down to 1 and unchecked all there is to uncheck in that section.

Thanks

We have an article but I don't know how much difference it makes: Firefox uses too much memory or CPU resources - How to fix.

I left firefox open on the default home page and now it is using 480 MB with only one tab open.
