Firefox crashes and is extremely slow

For many months now, I think since ESR 52.0 update, Firefox is extremely slow. For example, when reading a wikipedia page it takes up to 2 minutes to get the scroll function to respond and move down the page a few lines. Process explorer shows an extremely large number of page faults >7,000, FF gets increasingly slower when I use it more than 10-15 minutes a day and crashes almost every time I close and restart. The crasing threads are all file access operations. From what I observe, there is a similarity to an issue I had 40 years ago when I wrote a multivariance statistics program using matrix calculations. The first few drafts were slow, taking more than 2 days to complete the calculation on a small test database. After careful analysis of the compiler and runtime system, I was able to find the appropriate order for the FOR-NEXT loops such that I minimized the number of disk accesses. The program then finished the calculation on the test database in less than 2 hours. It seems that something similar has occurred in recent revisions of Firefox. I think someone needs to examine the methods for allocating and using computer memory vs. disk memory being used by programmers.

I followed your instruction. Used Piriform's CCleaner. There were no problems at any stage of the process.

Absolutely no difference in the severely degraded performance I have been experiencing. Even Netscape was faster with on a computer with an 8088 chip and 2400 bps modem connection to the internet.
