My Google search preferences include:
1. Show 100 results per page.
2. Do not filter the results.
Today once again I found that my settings had somehow been reset to 10 results per page instead of 100, and to moderate filtering instead of no filtering.
I haven't kept track of how many times these settings have been changed but would estimate that on the average it happens about every three months. In addition, I've had to turn my search history off (or "pause" it) at least four or five times after it was turned back on without my knowledge.
Can anyone explain this?
