* Popup Blocker (Strict) - this is another anti-annoyance thing. It will block more popups than your browser typically will.

* Protect My Choices - ad tracker opt out software from the Digital Advertising Alliance https://youradchoices.com/pmc (This shouldn't matter because Ghostery and uBlock are already blocking the trackers, but if there are any new ones or ones slipping through, I'm opted-out of targeted advertising from them)

* RoboForm Password Manager - so Opera is not saving any of my autofill data. I can't recommend this software enough. I've been using it for at least 15 years. It automatically saves all my usernames and randomly generated passwords to a cloud based server that was custom written by the company that made it (so it has no chance of being broken into like Apache or MySQL), you have one password, a master password, which Roboform doesn't know, and encrypts all your files on the cloud in AES encryption, so it will also auto-fill login and password fields on your phone as well. I use this everyday all day 24/7. https://tinyurl.com/RoboFormPasswordManager123 It's ABSOLUTELY worth every penny and much better than the free alternatives out there.
* ZoneAlarm Anti-Ransomwear - due to all the ransomwear attacks, I found this to be one of the better solutions. It backs up your files and puts random folders all over your HDD with random files inside. These files should never be accessed under any circumstances, so when it detects them being modified, it will lock your PC so the ransomwear attack is stopped in it's tracks.

There are also some very interesting tools from a company called CyDec Security. They make a browser extension called Anti-FP which is an all in one anti-fingerprinting tool with a variety of options, but you have to read the manual to learn how to use it properly. https://www.cydecsecurity.com/
They also make a tool called Browser Bubble which costs $50, but if it does what it claims, would make your browser completely bulletproof: https://www.cydecsecurity.com/bubble.html
