this scripting garbage does not work i have set the value high and it still unresponsive, can we get rid of this garbage or do i find a different browser that works

Start firefox and spinning pizza wheel wait till unresponsive script error, kill that script continues to load select email and spinning pizza wheel unresponsive script error again, kill that one off, i have set the value as high as i can but still this garbage scripting still has unresponsive scripting i kill the third and i will get maybe 20 minutes of response then we go back to the spinning pizza wheel, Who is responsible for this obvious Lack of scripting, is it really that necessary to have a system that is unusable because someone had a brain F*** and cannot do one simple thing and make something work CORRECTLY == This happened == Every time Firefox opened == The last 3 updates of this mess.
