Hello everyone.

I've been having some issues with Mozilla lately. I don't know if my CPU is in bad condition or not but, when I change tabs through my Windows, say changing tabs from Mozilla to Spotify and changing it back to Mozilla, my CPU gets very full, causing my cursor to lag, and Mozilla to be unresponsive for a couple of seconds first and it gets kinda worse as I continue to use my PC, causing the lag to occur for over 10 seconds.

I have seen some similar complaints on the web but they date back to 2014ish times.

What do you think? Is it somewhat my CPU's problem or did Mozilla's handling get worse over a patch or something?

I enjoy Mozilla and don't want to quit using it. Any help would be much appreciated.

I am trying to move one tab from one window to another. It says I should be able to move it just by clicking on the tab and dragging it to the window I want to move it to. But, when I try this nothing happens, it won't move.

Want can I do to resolve this?

Thanks

As of last week, FF works for a few minutes on startup, but then when you open a new tab and try to go to a site you just get the dancing period, nothing opens. Already open tabs with sites generally still work, but sometimes crash the tabs after a bit. We've tried starting without extensions, uninstalling and reinstalling FF, changing the profile, logging in the PC (Win 10, up to date) with a different login, running SFC and DISM on the PC, and just about everything else.

Opening the FF console shows this message when the tab just rocks the period:

WindowsJumpLists: Failed to fetch favicon for https://online.adp.com/signin/v1/?APPID=WFNPortal&productId=80e309c3-7085-bae1-e053-3505430b5495&returnURL=https://workforcenow.adp.com/&callingAppId=WFN&TARGET=-SM-https://workforcenow.adp.com/theme/admin.html NS_ERROR_FAILURE: WindowsJumpLists.sys.mjs:257:29

Edge works perfectly (and unfortunately, I'm having to use Edge to enter this ticket.). Other applications don't have any issues. I'm not having this issue on 2 other similar PCs I have that run FF, only this one.

Any ideas of what might be the issue with FF on this PC? Thanks, Alex
