Slooooooooow and laaaaaags
Ever since the last Firefox update cruising on Facebook is an outright NIGHTMARE. Videos lag. Page changes lag. Open messenger, LAG. Check notifications, lag!. Lag, lag, lag, lag. It was never like this before. I have cleared the cache, deleted cookies, checked for updates, and nothing works. What ever was done in that last "update" needs to be undone to fix it.
