Firefox gets super slow when I highlight text.
The browser lags when I try to scroll up or down. It's even worse if I double click to highlight; it just freezes for a few seconds. I think this started happening after the latest update.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe Mode start window.

Try to disable hardware acceleration in Firefox (you need to close and restart Firefox).
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

The problem persists with it on or off.

I think it was the LastPass addon. I reinstalled it and everything seems fine for now.
