Firefox Community Forum

I cannot get Firefox to accept session cookies. I have my cookies set to standard in the settings. I have also set my permissions to allow cookies from the website where I am trying to view an embedded video. I set the permission by using Ctr-i. When I reload the webpage, for the briefest moment it looks like the video is loading, but then it reverts to "Access Denied".

Dear Firefox Support Team,

I have been a devoted Firefox user for about five years, across both desktop and mobile. I truly love Firefox for its speed, privacy, and customization. However, for the past one to two years, I've encountered a persistent issue on my desktop where Firefox resets unexpectedly. Even though my extensions, passwords, and settings remain, I’m repeatedly logged out of my favorite sites like YouTube, Gmail, and Facebook. Despite reinstalling and troubleshooting, the problem persists. I trust Firefox so much, and I hope you can help me figure out what’s happening so I can continue using it with the same joy I always have.

Thank you so much for your help! Best regards, Md Muhidur Rahman from Bangladesh

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?"

I have set my firefox, that it deletes all cookies after a session. additionally i have stored some exeptions of this routine. But now also the cookies of the exeptione are delete every week, mostla on sundays! what is the reason of this behavior???

Previously, each time I logged into Firefox, all my various streaming services and other apps remained logged in. Now, every time Firefox goes to sleep or is re-booted, I have to log back into all the streaming services, Google, Facebook, Yahoo, SideReel, etc. Sometimes this happens several times per day.

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.

see question, please. using win10 (because of compat issues with some of my development software. if i make a change to one of my websites (reload a modified page), i have to get out of firefox so cookies will be deleted. That's a bit painful, as i am making a lot of web changes on my servers just now. The circular "reload page" button does not always help. thank you

Hello. I've got a simple suggestion.

When we go to "manage data" in settings. We can only remove a particular cookie, or all cookies from websites. I would love for there to be a block feature there.

The only way to do so now is by going to "manage exceptions" and typing out the URL manually. I'm finding certain URLs becoming more and more tedious to type out. I feel this would really help. Perhaps they could merge "manage data" and "manage exceptions" together and just put all the features in one place.

We've got all kinds of great extensions that can cut down on the annoying cookies and pop ups but I still feel this would be helpful.

I prefer all my login accounts to log out when I close Firefox. All of my settings are set up to do so, nothing changed, yet suddenly for the last week or so, it has simply stopped logging me out. Every day when I log in, there everything is again. I keep rechecking all my settings, even turning them back off and on, and nothing is fixing this. What's going on?

I asked this same question in Reddit and got a reply to uncheck "delete cookies and site data when Firefox is closed", close all Firefox windows, and reopen them, and this did not correct the problem. Please advise.

When I put my laptop to sleep, websites I am logged into are often logged out when I return. Note that I don't close Firefox. The tabs generally reopen but require login again. Windows 11, Firefox 137.0.1

For example, I put my laptop to sleep for lunch. When I returned, tabs were there, but I was logged out of gmail, Discord, and a website I was logged into.

This seems to happen more frequently recently, but not every time, as far as I know. But this is a relatively new problem, possibly related to a new laptop. Occasionally I get a message that there is trouble restoring my session.

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??

Trying to add my yahoo email account to Gmail. Keep getting message Must enable cookies on browser for yahoo account.

Have tried Firefox process shown in past posts. Keep getting redirected to same page on how to enable cookies.

Screenshots shown on earlier posts by “Jon…” not legible.

Thanks for your help!!

The image I uploaded is all I am getting. I even got on line one on one with my McAfee and they got on my computer. I need help guys. Is not just browse, I am also having issues accessing the website I know my account has been compromise. All I did different is add 2 adds on that were recommended by Mozilla and I removed them but it looks like the damage was already done.
