Simply scrolling support page causes 100% CPU & high memory!!
I've been experiencing high cpu & memory on my 98SE. No,kidding! 8.1 pro... Now I'll admit I have crappy internet service and I sometime have 10 tabs going when in the crypto markets so I;m not expecting perfection. I'm familiar with the fixes and have tried most. Private browsing seems to work best but I constantly have to reset options like graphs I use so that's a pain. If I zoom my screen in to say 80% some graphics wont load on a few webpages as well. I was just reading about the issue in this support forum. Following on a point made I clicked the task manager tab (already opened) and for a sec it flashed "81%" ???? I tried it a few times with similar results. I reduced the window to about 80% of the screen and put task manager on the side with a google search page and this tab open. Extensions,only adblocker plus.
Just scrolling up/down this page causes the 2 FF background processes to go from near 0 up to 16 & 18 (about) If I scroll up/down real fast I can get it to 100%. MPC-HC in the background is also causing Firefox CPU to be higher! If I pause music & do nothing the FF processes all go down to 3 or to 0. Seems it may be something in the networking service host or maybe just some corruption. Will post back when I figure it out. I hava a feeling that a lot of the people with high CPU / memory issues have PC problems.

Thanks, I've done all those and it didn't change. That's actually how most of those settings are now. I can usually fix stuff before I get a response on forums so usually don't post. Appears to be fixed now. I redownloaded FF after uninstalling & deleting folder as westend said. Wasn't much in the folder. Slight if any improvement. Found out mouse thing is normal....it's busy trying to figure out where we r going. lol Searching for prob. I tried inspect element on Bittrex where i'm at all the time. It had"Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource" and a lot of "Unknown pseudo-class or pseudo-element" "Unknown property ‘user-select" and "parsing" errors. Ended up at system error log files which wouldn't open....odd, was working fine recently.Services wouldn't start,registry settings were correct (issue some had) In fixing that I ran across a post on resetting all your folder permissions with microsoft subinacl and a pastable notepad script. ( says Subinacl is for XP but it works with 8,8.1 and 10 too.) I remembered I had changed a permission (in services) recently and never changed it back (NTAuthority) but couldn't find it again. I had some malware corruption a while back as well and had to replace some files. Dism.,sfcscanow obviously don't check permissions as they both came out clean. Figured might as well get that straight while there. Copied the code into notepad,saved to desktop, double clicked to run. That must have been the prob. Tethered with my phone,I have 7 tabs open,(running on 2 FF processes) 3 screenshots open,notepad open and running music videos on mpc-hc..... Cpu staying under 50% and no longer jumping. If anyone needs the script,google subinacl + manage permissions and you'll find it easy. Real neat script and if you have to manage a lot....a real time saver. thanks for the help!!!
p.s. Don't just assume it's FF hogging up you resources or u may never find the true cause!!

Did you first complete uninstall any FF and deleted the Mozilla folder before install FF57+.
not sure if i deleted the Mozilla folder ...i'll try
(Westend what does that have to do with anything)
To be Checked and turned off unless needed for accessibility : Please : go to the Firefox 3 Bar Menu --> Options --> Privacy & Security panel and under Permissions check (put a tick in the box) the setting to Prevent Accessibility Services from accessing your browser.
Multi-Processor Support : Go to the 3 Bar Menu then Options --> General --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 1 = No Multiprocessor = slow again. Try 2 Restart Firefox after making these changes please. Note : Hardware Acceleration is for Video Card, Monitor to see if remain off or to turn back on.
Only Disable as last resort.
Multi-processor Can completely disable it this way in about:config : dom.ipc.processCount set to 1 browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false
Only move to esr if low ram and old system.
Firefox Extended Release Version : Firefox ESR does not come with the latest features but it has the latest security and stability fixes.
If do please :

Oh yeah, sorry, the error log file service and a couple others related not opening was because of a a folder in system32 (can't remember which one) didn't have an owner in advanced security,they said to put SYSTEM in and give it full permission then reboot. which worked (And also how I found the permissions reset)
