Diễn đàn hỗ trợ Firefox

I just tried to open Firefox and got the message "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem". DO NOT redirect to this link

It is useless. I tried to restore 3953 items from a previous back up and received the message "Unable to process the backup file".

I am not interested in hearing how to prevent this problem in the future, because obviously creating backups do not work.

How do I check to see if the problem was caused by security software, even though I have not added anything?

1. I use a startpage called IGHome. That address is set as my default to open to. When it opens I notice that the address is not secure. When I add https:// in front of it, it does in-fact open, which is good. Even though I added that prefix to the address on the Internet Options page in my system, it still continues to open the old 'unsecured' way. I also cleaned IGHome out of my system before resaving it. Is there anyway to get my system to recognize the secure version? And, if I open any sites with passwords on the unsecured version, they DO open as secured so in reality I am still safe (even though my system is not opening the https site).

2. Also, on my IGHome page, there are 'Show Your History' and 'Show your Bookmarks' tabs at the top right in the toolbar. When I used to open them they would open almost flush right. Now they open almost in the center. Is there a way to make them open in their previous flush right location again?

Thank you in-advance for any time and assistance!
