I cannot download PDF files and have many other problems with updates since 3.6.18 are you guys going to fix or should I switch to IE?

Question

Hi Guys,
I have had heaps of trouble with plugins and add on's since using upgrades after 3.6.18. Now I cannot download PDF files!
Are you Guys going to fix what used to be a good browser or do I have to use IE?
Please keep it simple.

-> go to Help Menu -> select "Restart with Add-ons Disabled"
Firefox will close then it will open up with just basic Firefox. Now do this:
-> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE any Unwanted/Suspicious Extensions (add-ons) -> Restart Firefox
-> Update ALL your Firefox Plug-ins https://www.mozilla.com/en-US/plugincheck/
-> go to View Menu -> Zoom -> click "Reset"
-> go to View Menu -> Page Style -> select "Basic Page Style"
-> go Tools Menu -> Clear Recent History -> '''''Time range to clear: select EVERYTHING''''' -> click Details (small arrow) button -> place Checkmarks on ALL Options -> click "Clear Now"
-> go to Tools Menu -> Options -> General -> '''''When Firefox starts : select "Show My Home Page"''''' -> Type the address of the website which you want to be your HomePage e.g. http:www.google.com -> click OK
You can enable the Trustworthy Add-ons later. Check and tell if its working.
