I found 1KB file, i doubt that this can fix anything.
Using uninstall with fix it option, it did reset browser, but second run was the same as before.
I have deleted Maxthon folder in roaming folder and start over after uninstalling and it worked.
What's your point, i don't use drop down bookmarks menu, i have removed that option anyway.
Less work if i just use any other browser out there.
You don't even have an ad blocker in your extension center?
