Resetting Firefox made it worse; is slow, it crashes, won't open web pages, what do I do?

I had Windows 8/1 on my Dell Desktop PC XPS 8500 with 24GB memory; a fast machine. I have a solid internet connection through my telephone company, CenturyLink; always works excellently. Firefox worked great. Then, last week or so I downloaded the upgrade to Windows 10 and since then, I keep having problems. Firefox has slowed to a crawl, when it does work. It often crashes, the web pages I go to often won't open. I tried re-setting my modem; no improvement. I "asked" Mozilla how to fix and the answer I received online made no sense. My Firefox - which is the latest - didn't have any of the places the answer told me to go to. The 4-line icon does not open to "options," like the answer said. I am not an expert, obviously, but I am also not an idiot. I can follow directions except the directions I received did not apply to anything I could find on my Firefox of my display screen. When I re-set Firefox I lost too much of what I had saved; I will not do that again. Is there a problem with Windows 10 and Firefox? Like I said, on 8.1 everything was exceptional. Is there a conflict with any software I am using? Where do I look for answers? Also, I could NOT access the Firefox Health Report. The directions to find it I received do not correspond to anything on my Firefox page or my Options. I don't know what to do. Please, I hope you can help me.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. Is the problem still there?

While still in Safe Mode,

Some of your crash reports weren’t sent to the Mozilla Servers.

In the address bar, type about:crashes<enter>. Note: If any reports do not have BP in front of the numbers/letters, click it and select Submit.
