In the past, when I would download a Firefox update to my laptop, when I cleared the Cookies and Data, there would be zero remaining. Now, every time I download a Firefox update 24KB of data remain and will not clear when I push the Clear Data button. If there is more in the Cookies and Data file, when I push the Clear Data button most of what is there is removed but there is always 24KB that remains and will not clear.

1. Why has the Firefox updates started leaving 24KB permanently in the cookies and data file?

2. How are we to remove the remaining 24KB that does not clear when you push the Clear Data button?

I always delete ALL browsing data every time after using the internet. However, when I next go to use it there is a whole load more kB under "temporary cached files and pages". This usually happens overnight, but has also happened in the daytime. Why would this be? Does it mean someone has gained access to my laptop? Now more concerned as have had fraudulent use of my bank card today.

Non-technical language answers please!

Before closing Firefox, I go to: Privacy and Security, Clear data for specific sites, remove the sites I don't want. Then I go to Clear Browsing Data and check two boxes: clear Browsing and download history and Temporary cached files.

In spite of that, I see 50 - 100 MB in Google. I don't want that.

Therefore, I went to the Manage Exceptions list and added all the sites that I want to keep cookies and site data. I checked Save Changes. (Google is included in that list.)

However, if I return to Clear Browsing Data & Cookies, check Cookies & Site Data, then Clear, Firefox deletes all the sites stored in Managed Exceptions, too. It's not supposed to do that.

Questions: 1. How do I prevent that from happening? 2. Should I remove Google from Managed Exceptions list?

Please advise. Collis

It is been like 6 or 7 months now since i move to new pc and i been using firefox in this new pc together with other browsers. I am not really using firefox for anything related to google or gmail but just other website that have 0 relation to them. But i have still logged in my main accounts in firefox. It is been twice that once in a while, when i have to check my gmail accounts, all of them disappear and all i see is just sign in page only. There is no log in again or Please log in to this address or that address but straight up fresh page of google sign in page. I still logged back in when it first happened because i heard about the bug that happened with firefox update but now it happen again. It is as if my cookies just vanished but no, other sites still got their own cookies and there is many cache of other website here. other than my google accounts. What is happening here. Is my firefox bugged or something? Should i reinstall and have to relogin everything "again?"

Hello,

It seems that Firefox has lost the ability to clear cookies on exit without also clearing history. This affects the current version, 153, but I started observing it a few versions back, maybe around 148.

In Settings -> Privacy and Security, if I select "Clear cookies and site data every time you close Firefox", this automatically enables "Clear history when Firefox closes". If I unselect the latter, the former also becomes unselected.

I would like to clear site cookies and data whenever I close Firefox, but not browsing history. I'm sure this used to be possible in the past. Is it an intended change that this is no longer possible, or is it a mistake?

Thank you.

you have to delete over 5 times to get history and cookies to clear. Selecting "everything" never removes everything :( Used to be the best for privacy now its seemingly deceptive..

Firefox is storing an ever increasing amount of data on my device. It is up to over 600 MB and growing. This is fairly recent How do I access what data is being saved and clean up data that does not need to be using up memory on my device?

Hello,

in Firefox 154, it looks like there are 2 places if you want to create exceptions to clearing data when exiting.

1. In about:preferences#privacy under "Browsing data": "Exceptions - cookies and site data"

2. and in about:preferences#history: "Exceptions - clear history on shutdown"

The 1st place allows more than just an exception to clearing data on exit, it allows negative exceptions too (i.e. "block" and "session-only"), whereas the 2nd place does not have those, and is only an exception to clearing data on exit.

having both of those dialogues is pretty confusing and seems duplicative.

what are the under the hood differences between them, and which one should be preferred for exceptions to clearing data on exit?
