does firefox require 'warming up' ??

more options

Every single time I load F/F (especially for the first time) it takes So long to start When its started and I click on (example) on a desktop shortcut it takes so long to load After about 5 mins of going slow (like warming up) it then starts to go normal speed. I have tried all suggestions on googles...still the same Start FF ...goes so slow, and gets faster as the minutes go by

Is this all the time, or just during system bootup?

When any computer starts up, dozens of system programs are loading. This causes a 'bottle neck' until everything is loaded and running properly.

Other programs called by you only add to the 'bottle neck.' You will have to be patient until your system is ready.

One thing you can try is; When you leave the computer, try using 'Sleep' mode.

Is this not during system boot?

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Not during boot up.

I boot up all systems go...using the windows all is good, fast as ever. laptop maybe been on for 1 hr, then click F/F to load thats when it starts like warming up...very slow to start with takes about 5 mins + to load pages properly (fast) its like a car engine (old style car..LOL) where you needed to start it and let it warm up before it would work properly
