FIREFOX BECAME SUDDENLY VEEEEEEERY SLOW
I have being using Firefox 17.0.1 for a long time. It has been running flawlessly!!!! This morning Dec.11, 2012 I opened and started working as usual. After about 1.5h of working it started getting really slow. I mean it took seconds to go from one sheet to the next, it took 15sec to open a menu etc. Really slow!!!!!!! I shut it down a few times, I rebooted my system but nothing changed. All other programs I work are running without problems. I used EXPLORER to get on with my job and every now and then I tried FIREFOX again (which was always open). Then it suddenly came back to normal. I worked for about another 2.5h in FIREFOX without any problems and then suddenly it slowed down again. I tried closing it and opening it up again and it never opened. It just loaded and loaded. So I killed it. I uninstalled it and re-installed it. Still the same problem.
I am using windows 7, 64bit HP elitebook. FIREFOX has been running smoothly for a very long time.
As far as I can know, I have not done any updates at all today (windows, Firefox or other)
What is the problem?

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:
- Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
- Under "Time range to clear", select "Everything".
- Now, click the arrow next to Details to toggle the Details list active.
- From the details list, check Cache and Cookies and uncheck everything else.
- Now click the Clear now button.
Further information can be found in the Clear your cache, history and other personal information in Firefox article.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
