For the last few days after an hour (or so) of use, browser windows try to load but don't finish. I checked the Mac activity monitor and see that FirefoxCP webextensions is hogging memory--8GB! MacOS 26.6.2, Firefox for mac 154.0.1. Did the same thing for MacOS26.5.2. Is AI doing in performance? How can I find what to turn off?

I'm on FF 154.0. The power went out here and when it came back and I booted the desktop computer something had changed in FF.

I used to see the active tab as green in the tab bar and yellow for the rest, but now they're all gray until I mouse over the bar and only then does it turn green/yellow.

I struggled with this for many hours trying many //active tab color// solutions I found in searches but nothing got it back to my old behavior.

So as a last resort I tried adding the Firefox Color extension, but when I click Add to Firefox it just turns into a throbber that never changes so it doesn't install. I'm stuck!

Frustrated!!
