it's not good practice privacy-wise. You can be easily tracked even if you've changed domain. If you open several pages in the same tab every previous website has d position to track you if they do use certain cookies. Even if you open different websites in different tabs, still you are under threat. Cookie-hijacking is serious threat & you should delete cookies as early as possible. btw cookie autodelete also deletes cookies upon domain change.
HTTPS everywhere also blocks or hinders other websites to see your browsing session. It's not just bloody encryption. It blocks/hinders x website to see whether you've visited y website or not.
I'll take cookie auto delete into consideration. To be honest I'm just too lazy and my care for privacy has gone down a lot this past year. I still customize privacy settings in products as long as they're easy and fast to set.

& 
. You may also max up privazer's priority. & check start cleaning,
Does it disable securely erase(or whatever its called) when you clean? I don't want to clean it by making the files unrecoverable.
It seems so. Privazer deletes residual traces form free sector of disk either by resetting all those sectors to 0 or 1 or either random 0 & 1 or overwriting those sectors. So using aforementioned setting should disable securely erase. but if those free sectors already have been occupied by new files then you won't be able to recover your old files & it has nothing to do with privazer. Hope it helps.
instead
If it disables secure erasure, then I'll give it a try with those settings. Thanks.
Kaspersky Free is nice and light on system resources, but is also a very good program.
