Firefox is slow and hangs up
I am running Windows 7 Pro 64 bit. Within the last 10 days, Firefox has started hanging up. It started before the last update. I hoped the latest update would solve the issue but it has not. Some times the hangups lasts for a 3 or 4 seconds, sometimes much longer and the screen turns gray and stops responding for 15 to 20 seconds. During the hangups, it responds neither to the mouse or keyboard. I have started it with add-ons disabled. I have done a refresh and nothing helps. I have used Firefox since 1.0PR in 2004 and I don't want to stop now. Chrome and Internet Explorer work fine. All other programs on my PC work fine. I have installed no new software on the PC. I have installed no new extensions in Firefox.
Firefox is working fine on my Ubuntu 32 bit PC

Additional information. It seems as if the longer Firefox is running, the slower it gets. When I first start it, it will seem to work ok then as time progresses, it gets slower and slower. It gets so slow that, and this is just one example, I cannot control a YouTube video. Navigating other websites is equally slow.
Well, Firefox just made a liar out of me. Now it's doing the exact same thing on Ubuntu. The screen just turned gray and froze. No response. 55.0.2 32bit
See if using muli-core. https://arstechnica.com/information-technology/2017/06/firefox-multiple-content-processes/ if are then check task manager and see what sort of resources they are using. Also note it can cause issues running it. If not using multi-core you may want to enable that function (as above article states some Extensions disable multi-core like Norton Toolbar until ver 57)
Windows 7 is not being Supported by MS as it should (articles have read) Some users are going to ver 54 of the Extended Release Version.
See if this helps at all : 1. Repair System Registry and Files (FOR DOING Above & Below - WINDOWS All OTHER VERSIONS - Use Search To Find Command Prompt ** Enter CMD.exe to Find COMMAND PROMPT Then Right Click & RUN AS ADMIN)
To run the SFC command use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin). Type "SFC /SCANNOW" (without quotes or copy/paste) and press Enter.

Thanks for the response! I know you put a lot of effort into this reply.
I did everything you suggested and when I got down to the DISM part, I did not know how to start and run it so I did research on how to. My research says DISM is not available on Windows 7, only Windows 8 and above?
No crash reports have been generated. Firefox does not crash, it just slows to a crawl and becomes so slow as to be unusable.
I did everything you suggested and I will monitor it for the next day or so.
Next item, Firefox on Ubuntu. I narrowed down the issue to the following: When I would select View, Bookmark Toolbar, it would freeze and gray the screen. I would shut down Firefox and try again. Same thing over and over. Then I did a Ubuntu software update check and the OS updated and Firefox now works correctly on Ubuntu.
Again, thanks very much!
