Firefox Support Forum

I have changed my settings to permanent private browsing mode, and never remember any history, cookies or anything else, but yet still somehow my Firefox is storing cookies under the head "Cached Web Content", and i have to manually delete them after using my browser for some time, Can anyone help and tell me why is it happening and what can i do to fix it?

Just upgraded to latest version for windows 10. Accidentally checked the box that says to Run in private windows. Now Firefox will only open websites in Private Windows. How do I fix this issue?

Hey, I'm using the restore previous session feature. Its really helpful, but I assume since the last update it is not working properly. Whenever I use the private firefox browser (window) parallel to the normal one (window) and close the normal browser before the private one, my last active session of the normal browser is not restored.

When I close the private firefox window before the normal firefox browser window everything works fine with restoring the tabs.

Any way around? And please fix this annoying bug. Thanks!

Open Firefox. Verify no cookies. Clear any cookies if they exist.

Then open a single private window.

Go to tripadvisor.com (happens with some other sites but only a few).

Browse a few pages.

Close the private Window. No private windows/Container tabs are open.

All tripadvisor cookies should be cleared but they are not.

Verified by Cookie Quick Manager.

Why and how does tripadvisor manage to keep cookies on my system.

Refreshed Firefox on my computer after getting a message that it was performing slowly. Now I am unable to open private browsing.

If I type in about:privatebrowsing then I get the private browsing screen however if I type anything in to that screen to search for it reverts to normal browsing.

I’m a silver surfer so not the most technically minded but does anyone have any suggestions as to how I can get private browsing back. Have used Firefox for quite a long time with no issues before this so don’t really want to change to a different browser.

Can confirm using Windows 7.

Thanking you in anticipation.

After the latest update Firefox stores cookies and site data even in always private and the content blocking set to custom with everything set it the highest settings. Example i can check my email at outlook com then sign out click forget, then close the browser. then open it and it loads my email account without signing in. The only way it can do that is, the browser is storing cookies and site data. the only way to prevent it from doing this is to do everything i described then open the privacy settings and clear cookies, and site data and clear history, two times. Firefox like this is the most unsecured browser. it was a lot better before all these changes. It was a good idea, but it's caused a lot of troubles with security issues for me.

I use Firefox in private browsing by default. However, that means that I always have to login to any website, which can be a pain.

I was wondering if there is some middle ground. For example, if I could whitelist cookies from a specific domain to persist across private mode sessions or to be imported from non-private browsing. I am aware that I could be tracked by those domains, but that is a compromise I'm happy with.

Hello, I'm here more to report a bug than to ask a question, but I couldn't get myself to work with Bugzilla, it asks too many things.

So you know how sometimes you open a bunch of tabs in "Private Browsing" just so you have a separate window to close everything at once when it's not needed anymore, well usually in the case of Chrome and Edge, it clears the ram that window was using, instantly no problem... Firefox doesn't really do that and I find it quite worrying if you call it "Private browsing", in fact, closing tabs doesn't really seem to close them at all!

In chrome, when you close 10 tabs you see the ram usage dropping quite clearly, with Firefox it just stays there and it's even worse when I close the whole private window and because I have a normal Firefox window still open, it doesn't clear any ram!

Yesterday I had windows explorer crash because of this and it closed word while I was working on it, go to task manager and Firefox is using 5GB of ram with 5 tabs open... Every damn day I use lots of tabs I have to close Firefox completely and open it again with the same goddamn saved tabs to clear 3gb of memory or more!

Really I want to like this browser, but first of all, this must be a horrible programming practice and second I doubt this is safe at all, keeping closed tabs for hours in memory waiting for the program to close can't be safe, it just can't!

How to reproduce this memory leak? Have Firefox with a normal window open, then open another normal or private browsing window, open a bunch of tabs there, watch memory usage rise, then close that window and watch it not drop at all. Way around it? Close Firefox and re-open. Could it be an add-on bug? Maybe, you tell me if it works with you, but it would still mean there's a bug with Firefox itself.

Really simple, I have no idea why this is a thing, isn't it supposed to have a separate process that clears memory when you close it? I have my doubts it's working like that.

Hi,

I have an issue where a modal works in regular Firefox, but not when private mode is used. And, there is no "Allow/Block pop-ups for this site" information bar in Firefox's private browsing when the issue occurs - nor was that setting previously disabled.

I'm running Firefox version 62.0. It says it's up-to-date. I cleared browser cache and the issue still occurs.

Steps to replicate: 1. Open regular Firefox 2. Go to https://flexithemes.com/ and click on any theme. 3. Under the image, click the download button and the modal appears. 4. Open a new private window in Firefox 5. Repeat #2 6. Under the image, click the download button and no modal appears. Instead, a # is added to the end of the URL.

Is this a bug or a feature? If a feature, is there a way to get the "Allow/Block pop-ups for this site" information bar in Firefox's private browsing when the issue occurs?

If it's a bug in Firefox, where should I report it? And are there any workarounds until it's fixed?

Thanks!

I have a bunch of incognito tabs opened up, but I can’t do anything with them. I can’t scroll through tabs from left to right, I can’t drag them out of the window, I can’t add them to my bookmarks, I can’t refresh them. When I hover the mouse cursor over one of these tabs, it’ll show the name of a website/tab that I already closed before this problem occured. The thing is, I can click the bookmark button, the refresh button and the ‘close tab’ button, and the buttons will become darker as if it they’re working, but instead of it actually following up with the action, a small white rectangle shows up next to my mouse cursor.

I don’t know what to do and I don’t want to lose these tabs. Does anyone know what I can do to get them to respond to my actions?

One day for no apparent reason my gmail page would not load. I discovered that it will load on a private window. But I did nothing to cause this and don't know how to restore it so I can use Gmail normally

I visited some questionable websites in private browsing mode. Since then I have been receiving a large number of spam email. It seems private browsing is not private.
