Firefox version 36 takes a long time (35 sec) to initialize. Previous version comes up in 4sec. Running win7, even tried the refresh option, but didn't work.
I updated to version 36 and it takes approx. 35 sec to load. I tried to refresh option, and that was no help. The previous version quickly loaded with no issues. I looked at the health report and now taking over 50 sec. All virus scans (Norton 360) are up to date, and no malware.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one. Windows 8 has antivirus built-in already.
