What account?

Please explain the problem in detail. What happens? What are the exact error message(s) ?

No error messages, when i log out of my Firefox account on PC, all my passwords, bookmarks and history remains on the browser.

This didn't happen before, I'm guessing there was an update.

Why would you want all that info to remain on the browser, when you sign out? It doesn't make sense

The browser is supposed to save such data. Why do you want to remove it?

I am wanting to understand. Firefox can be set up to remove all data, but most of us want to save the data to use later.

I want it to remove all data when i sign out of that browser.

Example: I log onto Firefox on a pc that is not mine, example at work, or on a friends computer.

I see. May I suggest,

http://portableapps.com/apps/internet/firefox_portable Mozilla Firefox, Portable Edition

https://portableapps.com/apps/internet/firefox-portable-esr Mozilla Firefox ESR, Portable Edition

A fully functional package of Firefox optimized for use on a USB key drive. A specialized launcher will allow most favorite extensions to work as you switch computers.

Firefox Portable is a 3rd-party build. Support is available here: http://portableapps.com/forums/support/firefox_portable

You can use sync to share data between profiles. But some data cannot be shared between different versions.

Type about:preferences#privacy<enter> in the address bar. The button next to History, select Use Custom Settings.

Turn on Remember My Browsing And Download History At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on Everything.

Firefox Private Browsing is great for viewing websites without saving things like cookies, temp files, and a history of the pages you visit.

Yes, this is a change in Firefox 71: when you disconnect Firefox from your Firefox Account, there is no longer a dialog asking if you want to flush all the local data. Probably too many people used that by accident?

Your options are:

(A) Use a PortableApps build of Firefox as mentioned by Fred McD

(B) Remove data manually through one of two methods:

[i] A combination of dialogs to remove history/cookies/etc. and file removals to completely get rid of bookmarks/passwords

[ii] Create your own profile on the machine before connecting and delete it afterwards

It's a dumb update, the private user data, bookmarks, history, passwords should be erased when a user logs his account out.

Thank you for your suggestions I will try to see what works, best.

As jacocoj says... this is a dumb update. Security should be paramount. If you log out ...you log out. No if's and's and but's. What is being said to do is not an answer - it's a work-around to a BAD error in FF, and I'm dissappointed to hear it because it also puts FireFox in a bad light. Just because some users make a mistake with logging out and flushing local data is no excuse for sloppy protection - you can't expect users to go through a list of options - that's plain silly. So, I'm going to have to go back to bulky ol'Chrome Browser until you guys get serious...

When you clear data manually in Windows then this data isn't removed securely, so in principle it is easy to restore/recover deleted data, especially on a Windows computer (only a delete flag is set in the MFT).

Eh? I don't know what version of FireFox you're running but the latest has a button embedded in the History field. And anyway, we're not trying to save history, we're trying to stop our user login information from being accessed when we've logged out.

NB: FireFox support - when you type a comment and then upload an image to support the comment, and then want to check the image before you post, there does not seem to be a button to close the image first, meaning that you have to click backwards and loose the comment.

And exactly how does that help our situation?

This is extremely serious security flaw in situations where people are forced to use shared work stations for what ever reason, no matter if they are public or semi-public (shared work environment, etc).

Dev team should understand that quite a few users modify their accounts so thoroughly that it is impossible to start removing extensions, saved user account information and plethora of bookmarks - some very sensitive in nature (for example family matters, health information and so on) - manually after each time they sign in and sign out. Users might even be needed to jump in and out several times during a working shift (like me), depending on their working conditions.

Mentioned "flushing" all the account information worked like a charm for me thus far -> went to vacation -> came back to work and BOOOM, I am stuck in a working station with all the private information Syncing downloaded and forced to use time I can not afford trying to manually reverse the disaster. Even the full browser uninstall wont work b/c I lack the admin rights... I really do not know what to make of this--this decision is so bad, I got to wonder did those who made the decision fall into their heads at some point?

Who the hell was so smart they got even an idea of removing such an IMPORTANT PRIVACY FEATURE from maybe the most secure browser around? Now, one commentator above said it was most likely removed b/c people used it by accident... that just do not make any sense at all!

That feature flushed LOCAL data like it was supposed to do, not the data from an account in the cloud. So if one accidentally does it, one JUST SYNCS AGAIN. Takes few seconds, less than two minutes in any case. There is no actual harm in it -- but being stuck with a computer with your sentive information in it you can not delete fast -- now there is harm in there! So if that really was the reason for disabling the feature, the decision is even worse because then it was based on flawed understanding of the problem and security over all.

One work-around came to my mind, but I do not know how to enable this or even if it would work until the dev team comes to their senses -> using an older build of FF which still has this feature enabled. But I wont even know where to download one...

Several people have referred to 'work-arounds' but why should there be a need for a 'work-around'? Security should be absolute number 1 priority. Users should not be forced into fiddling around with FF. Annoyingly, Mozilla splash advertising all over the place promoting their security with such transparently erroneous headlines such as "Take back your privacy".

Exactly, Mozilla has branded itself as "privacy-first products" and i had to manually delete all my passwords one by one from the browser i was logged out of. But wait, that didn't work so i had to look for the file where they were stored.

They are taking steps back. Is there any way to bring this issue to attention at someone at Mozilla? Social media maybe? In the meantime I'm using a portable version.

I don't know, this is supposed to be run by Mozilla but the silence is deafening.

Could you please point out the file where they are saved to me please?

Also, it is said this problem is solved, which it definitely is not.

I proposed work-around b/c that is all we have got for now... sadly.

@legioonalainen It was the logins.json file in folder AppData\Roaming\Mozilla\Firefox\Profiles I think in the end i deleted the all of the files in the Profiles folders and reinstalled Firefox to remove my passwords.

Thank you.

It appears accessing even the drive would need admins at my end...

Removing this feature was a s e r i o u s security and privacy fuckup from teh devs, oh my goodness.

I set Firefox to not remember passwords. But it logs me in to my websites when my password manager is not running! Only after I clear the Firefox cache is it 'normal', but then I have to click all of the websites' cookies agreements every time, which is annoying. This can't be right
