Same for me on macOS 15 on a M2. It's just Firefox, and I don't run much in the way of extensions there. Just 1Password and uBlock Origin. I haven't noticed it

Same for me on macOS 15 on a M2. It's just Firefox, and I don't run much in the way of extensions there. Just 1Password and uBlock Origin. I haven't noticed it lately, but that's because I've switched to almost exclusively Claude usage as of late.
