As far as I’m concerned this is by far the most intrusive and inconsiderate update HP has every released. Be where – if I had to guess I would say that HP is using EDS to do it’s update/releases. I only say this because as someone who worked for EDS for 14 years, I can tell you they are used to telling their end user what they must have how they are going to get it instead of the other way around. This is one of the main reasons I left EDS in 1999. So do not trust HP anymore. Always make a restore point before you apply any updates and only apply update when they apply to you and the way you use your computer. I for one am going to turn off HP update notices because I don't even want to know about an update unless I have some problem I need to solve.
System Info:
OS: Windows Vista Home Premium SP2 32 bit (all current updates applied as of 01/15/2009).
Browser: Firefox 3.5.7
Problem Area: Firefox Add-ons
Problem and Solution:
Hp Update notified me an update for HP Smart Web Printing to version 4.60 is available. Because I like to keep my computer software up to date I clicked install, what a mistake. The first thing I noticed is that the Norton Toolbar 4.0 was missing in Firefox 3.5.7. Turned out it was BROKE and/or disables although Firefox showed it as being present and enabled it was not, along with other Add-ons for Firefox.
Things I tried:
1)      Exit and restarted FF (no effect) 
2)      Disable HP Smart Web Printing and Restarted Firefox (Norton Toolbar reappeared but still was not working along with other Add-ons.
Final Solution:
1)      Uninstall HP Smart Web Printing (I check delete/no to save anything)
2)      Ran System Restore and restored to the latest System Check Point which was before the 4.60 update was applied because Windows was prevented from or just didn't create an automatic restore point in order to undo the update.
3)      Uninstall HP Smart Web Printing again and again I didn't save anything (Why? I have no idea but it appeared that even though the previous version of HP Smart Web Printing should be installed it seems that the 4.60 updates are applied to it so it’s the only way I could get Firefox and the other Add-ons working right) Norton Safe Web still doesn't work right and is a 100% dysfunctional.
NOTE:
All Firefox Add-ons seems to be working except Norton Safe Web function. The green tick mark no longer show up so you have no way of know if the site is Safe or not until you click on a link in Google search so Safe Web will check it which as far as I'm concerned diminishes the protection/function 100%. The only solution may be to uninstall Firefox and reinstall it, which at this time I've not done because I am still trying to find a way around it.
