It seems that over the last two months firefox has been causing my hd to run at 100% for long periods. I have followed advice on the internet and disabled a number of searches within the pc settings that originally helped and also updated the power plan to high performance which initially helped.

Every hour or so my pc goes into a phase of running its hd at 100% to the point that I cannot even type in the search bar. Indeed it has taken over 30 minutes to finally get to the position of being able to type this query.

the pc is not that old and has light usage and all memory appears to be working fine. If this does not fix then I will have to go over to Chrome.

Hi, if you will please to eliminate any miners or other things that can cause issues : https://www.malwarebytes.com/

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. NOTE : you can move to this for stability reasons also

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 :
