2)lately whenever my laptop goes to monitor switoff or when my computer starts up a firefox window opens automatically with no themes enabled nor any addons enabled.the home page of the firefox window is the firefox google search page..I also did a virus scan with kaspersky 2010.

The setting Tools > Options > Privacy > History: "Remember visited pages for at least" refers to the number of days kept in memory (default is 90 days). Firefox 3 and 3.5/6 versions store pages in places.sqlite on disk for 180 days by default. ..... See https://developer.mozilla.org/En/Places_Expiration ..... You can look at these prefs on the about:config page. http://kb.mozillazine.org/browser.history_expire_days (180) (also affects saved form data) http://kb.mozillazine.org/browser.history_expire_days_min (90) (set via Tools > Options > Privacy > History: "Remember my browsing history for at least") --- For your other problem: See http://kb.mozillazine.org/Preferences_not_saved and How to fix preferences that won't save

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Safe mode start window. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")
