Hi, I’m having this issue with Firefox where it will try to reload/load all my tabs and my system CPU usage will jump to 100% and in the about:performance page it will show Firefox at 140% CPU usage.
I’ve tried to reinstall, Firefox. I’ve also tried removing extensions, as that’s where I think the problem might be coming from. But it didn’t seem to solve anything. I’ve also gone into about:config and set blockautorefresh to true, but this didn’t help either.
I was able to go into about:performance and extract one of the profile performance for the Firefox system. Furthermore, I however am not knowledgeable about Firefox and or web development and the services to understand and isolate the problem that is causing this issue.
I’m running on macOS, and I’ve only recently switched to Firefox, as I used to run Arc as my main browser.
Has anyone had any similar issues to this and are there any fixes that might work to prevent this from happening. It severely impacts my work as I’m not able to use Firefox until I restart it, and that would be happening ever 10–15 minutes.

    There’s an issue with the Simplify Copilot extension which is being updated to fix it.
