I have Windows 7 installed on my HP laptop. I am having a strange problem which I have never seen or heard of and so I am unable to solve it. I have seen that zoom percentage keeps changing with out any user approval. I have also seen that some my Firefox bookmarks have been lost on its own. I have consulted with my friends who are tech savvy but even they were unable to fix it. Can you help me to solve this?
