I have definitely seen something make the browser extremely laggy, but only the last few weeks. It does seem to be related to certain tabs/sites though, but I haven't figured out which.

For me it is Slack. Slack's JS leaks memory. Several times I notice Firefox really bogging down, I check about:memory and the Slack tab is eating 4GB of memory or more. Once it was nearly 7GB. So I've had to install an auto-reload extension[1] which simply reloads the Slack tab once an hour, and that contains Slacks stupidity. Now Firefox is nice and fast, even with hundreds of tabs across many windows.
