The majority of the sites on today's history are attempts to log in to a past employer, attempted Gmail admin log ins, the employers ticketing platform, searches for flights, visits to graphic novel sites, etc..NONE OF WHICH ARE ME! I though this was supposed to be a secure browser on an iMac? WTF is going on and how can I stop it?

Note: Windows users should download the ActiveX for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the ActiveX.

My guesses:

1. You have logged into a wrong account(like someone logged into his/her firefox account in your computer without your notice) 2. You have import old firefox data from somewhere or a html file. 3. you logged your firefox account in somewhere else (internet bar/ printing shop, etc), the history from that computer sync the footprints to your computer. your computer sync your history to that computer. 4. A virus is intrusively collecting your data. 5. your employer wife used your computer.

Accessible solutions

1. use firefox in safe mode by default 2. scan virus using some tools, like cleanMymac, .....so on 3. change your password to safer pattern 4. ask your wife.

Very good advice...and #5) is correct! Employer wife logged into and left that iMac synced to my Firefox account...therefore new employees plugging away on my browser and slowing everything down. Was able to un-sync remotely- and problem solved. Thank you for your input! Much appreciated!
