FF Memory SURGES when accessing finance.yahoo.com/

more options

For the last couple of weeks, whenever I access the finance.yahoo.com/ website, my computer slows to a crawl. I run Activity Monitor to show me FF memory usage has surged to 6.5 GB! I cannot just 'quit' FF, have to force quit to regain the memory. No problems with any other website. I am running Mac OS 12.7, 8GB RAM, FF 102.0.1

Any help/suggestions appreciated.

Regards, Peter Donlevy

Chosen solution

Problem does not occur in Troubleshoot Mode. (Thanks for suggestion, I was unaware of TS mode). Based on the number of adverts that appeared with TS turned on, I suspect the issue is linked to my use of Adblock Plus. Per, cor-el's suggestion, I will I try Ublock Origin for a smaller memory footprint. I will play around with this for a few days and report back.

8GB of ram... Just curious to know which mac are you on? You fail to provide detail on what exactly you have open when this issue occurs. When I visit the site, there is a bump in cpu usage, but it appears to be a lot going on with this site. You can see the windows and tabs I have open, but no issue. see screenshot

You can consider uBlock Origin as a replacement for your current Adblocker extension to see if that works better (lower memory footprint,less issues).

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

Does it still happen in Troubleshoot Mode?

Problem has not re-occurred since replacing Adblock Plus with Ublock Origin.
