I can't figure out why gmail will not allow me to log in. It tells me that cookies are turned off but I can't even figure out what that means or how to correct it

Think I've asked before, but I'm still having the same issue: in my Firefox (desktop, Windows 11), in the storage\default folder in my profile, there are, today, 5442 files! 416 folders appear here, with each one containing one or more folders ("Is", "idb", and/or "cache"), which, in turn, contain several files each, and a ".metadata-v2" file. The oldest of the 416 folders in 9/16/25. What is all this? I regularly delete all cookies over 30 days old in Manage Data.

Hello, I have some issues with Firefox keeping my logged in my Google account. When I close Firefox it logs me out of Google. I have tried some methods from other threads on this site but still without success. I have the setting for delete cookies on Firefox close to off and have tried Firefox remember history and use custom settings. Thank you for reading this.

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??

ブラウザゲームサイトUnityroomなどでゲームを遊んでいると、Cookieの容量が10ギガバイトを超えることがよくあります。 どうやら10ギガバイト以上のcookieをFirefoxでは保存できないようです。 FirefoxでのCookieの容量を10ギガバイト以上にしたり、ページごとに個別に管理できるようにしてほしいです。

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.

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.

I only cleared the cookie for Blogger and cleared my cache. I was logged out of Facebook, Grok, ChatGPT, Linked in and X and possibly more websites I haven't visited yet. I wasn't logged out of Google I don't think. I don't use Google for logging in anywhere and cookies aren't cleared when I close my browser.

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.

As has been mentioned many times before I am sure, it would be really helpful to be able to have a less laborious way to add exceptions but as I have been through the ridiculous process of typing in site addresses manually one by one without having any sensible way to record these addresses already I guess it won't help me now. The ridiculous aspect came from having to take screen shots of the list of sites from the manage data list after deleting everything not wanted, scrolling down a windows worth at a time, copying that screen shot into multiple copies of a graphics program then shrinking each copy of the graphics program and Firefox so each can be seen so I can manually type each address across.

I know I am supposed to be nice but this is just insane. It is 2025. There is a thing called copy and paste. Apparently some people at Mozilla are not aware of this.

Having got that off my chest the next issue is that the deletion of cookies and data only occurs when Firefox is closed. Who closes Firefox? Why would you close Firefox? I currently have 24 tabs open. Why on earth would I want to close them down just so they have to be selected one at a time and reloaded? What is the thinking behind this stupidity?

The only time I close Firefox down is when Windows is restarted for updates (every application) or when IDM needs to update as I found this negates the need to restart Windows (Firefox only).

Other than those situations I am trying to work out how to fit this cookies/data deletion into the normal operation of my computer. There appears to be a lack of a suitable way to deal with this situation. Would it be considered acceptable to just wait for those times Firefox has to be closed? This would be far better than what I have been doing up to now but why wouldn't Firefox delete this data when the last tab for a site is closed? There are a huge number of sites I bring up due to searching for something and close them immediately or after reading what they have to say.

I have been using computers for about 30 years and have long lost the inclination and to be honest the ability to delve deep into them. Today I just want to have them do what I want/need without unnecessary complications.

Have I got this situation right or is there something I have missed? At the moment IDM has been having a lot of updates thanks to YouTube's greed but before that I found I generally only had to restart my computer for MS updates and when strange things started to happen.
