Firefox Community Forum

While attempting to change my password in my TrendMicro antivirus, it was suggested that I clear my Firefox "Cookies & Site Data" and I cannot find that option in Firefox. How do I accomplish this task presently--it used to be so easy.

using linux cinnamon, have to continuously sign in to my sites. I didn't have to do this before. what can I do to stop the cookie deletion or whatever is causing this??

Hi.

With last updates on firefox desktop..(2 last updates)..every update reset all my websites logins..I had to relogin again in all my websites..what happened?..is normal?..or error?

I am following all the online instructions I can find to turn off private browsing on Firefox - in Privacy and Security by clicking on 'Remember History' for example, and also restarting laptop - but it is not working and I must constantly log back into all my accounts and websites, including my e-mail account. I need assistance with specific and exact instructions how to remove private browsing and explanation why not working what I have already tried. Thank-you for your assistance.

good morning,

I am having problems using a third-party website, playing chess, and one of the functions on their website is not available to me because I keep getting an error message. they have a forum on which I am discussing this issue with one of their Mod's, and he seems to be under the impression it has something to do with my Browser (Firefox 115.32.0esr) storing site data, and that the file in which this is stored has become corrupted in some way. I have no idea how he arrived at this conclusion but that is what he said.

I assured him that, "in Firefox, under <Privacy and Security>, in <Cookies and Site Data>, there is an option marked: "Delete cookies and site data when Firefox is closed." this has a tick box next to it and on my computer this has been selected for about the last five or six years. the browser does not retain site data or cookies and deletes them each time it closes. when I follow the instructions you linked to, and click <Manage Data>, there is no data to manage. it does not exist."

however, he replied to this that: "I don’t think that setting deletes Local Storage, though I’m not 100% certain."

one observation I make is that when I open the <Cookies and Site Data> <Manage Data> dialogue, the websites I have visited in the current session are listed. this data therefore does exist, and there must therefore be a file, even if only temporarily, containing this data. my question is about what exactly happens to this file when I close the session.

1) is the file emptied of data, but still exists as a file.

or

2) is the file physically deleted so that it no longer exists.

if, after the session, I reopen the browser and select the <Clear Data> dialogue and click <Clear> does this simply empty the file or does it physically delete the file. if the file still exists, is there any way to ensure that it is physically deleted in order to confirm that it is not corrupted in some way?

thank you.

i am getting an error message from one gmail.com email account and suggested to clear my firefox cache. Where is that

I tried to reach the following adress: https://www.itu.int/harmful-interference-to-rnss/ and I received this message on my browser: 400 Bad Request -Request Header Or Cookie Too Large

When I tried from a different browser it was accessible.
