I have firefox 24.0 in xp . for some time i have been using firefox with no problems. and i think i recently update to the current version. went my problem started I think was when I tried to download a video downloader. my home page was changed even tho I did a custom install. May home page was switched. after much trial and error I managed to get the home page I wanted when the browser first opens. but when I hit the tab button some home page opens that I dont recognise. and it does that for each addition tab that I open. it does this only when I open a tab. I have read several of the related questions here but there a waste of time because I am not a techie. looked at the about:config thing but finding the right thing to even begin to look at was impossible. I dont recognise any of the thing in there and I dint understand how to search for the thing it said search for. this is the instructions I tried to follow: Chosen solution You can modify the browser.newtab.url pref and change the value to http://foxnews.com Also make sure that the new tab page is enabled, the browser.newtabpage.enabled should be true. Type about:config in the location (address) bar and press the "Enter" key to open the about:config page, just like you open a website by typing the URL in the location bar. If you see a warning message then you can confirm that you want to access the about:config page. use the Search bar at the top of the about:config page to locate preferences more easily preferences that have been modified and do not have the default value show as bold (user set) preferences that are user set (bold) can be reset to the default value via the right-click context menu preferences can be changed via the right-click context menu: Modify (String or Integer) or Toggle (Boolean) or by double-clicking the line with the pref preferences can be created via the right-click context menu: New -> String, Integer, Boolean http://kb.mozillazine.org/about:config. what preference am I searching for? I tried searching for browser.newtab.url and came up blank. search for just browser came of with too many for me to make judgment on. This was very confusing and i could not figure it out until the asker came back and said it worked and something else that I cant find now. i think the answers should be dumbed down to where non-techies can understand. my problem is solved
