I have my Firefox Firefox Privacy & Security History settings set to 'Always Use Private Browsing Mode.' Yet every time I open Firefox and visit the History tab, 'Recently Closed Tabs' shows a history of the websites I've visited. How do I disable this feature?

How do I get rid of the automatic login options. I never saved the password. I just want to get rid of the options for the login field. There are too many, some don't apply. I have read everything and tried to clear my logins in the settings option, but the field is grayed out and I cannot select it.

Hello,

For a long time, I was able to launch Firefox on Windows with the startup switch "-private" which would cause it to launch directly into private browsing mode. I used that in a few local scripts, and created a shortcut to the executable, with this path:

"C:\Program Files\Mozilla Firefox\firefox.exe -private"

Just like that, it worked. Whether by shortcut, terminal command, or execution of a 3rd party script, that startup switch would always open a private browsing window. Until a few months ago, that is, when it suddenly stopped working. Rather than opening a private browsing window, it now does one of two things:

1. If FF was not already running, it opens FF to a tab showing a warning that I am not in private browsing, with a button I can click to launch a private browsing window. (see attached image) This tells me it recognized the startup switch, but...refused to honor it? 2. If a FF window is already open, it launches another (non-private) Firefox window, with no warning about not being in Private Browsing mode.

Was this an intentional change? Is that startup switch just not supported anymore? I tried a quick web search, but all I was finding were unhelpful suggestions like "right click on the FF icon" and "pin to start." Not what I'm looking for.

Thank you!

Trying to access my email account at Comcast, but recently (last few months) when signing in I get a blank page with the following message:

Firefox prevented this page from automatically redirecting to another page.

Followed by a link that says" Allow"

How can I correct this without having to "allow" each time?

thank you.

Hi! After recently following the upgrade path from FF v52 to the most recent FF version, I find that logins in logins.json did not carry over with the upgrade. Out of 555 logins, only 44 appear. (I suspect these may have been imported from Chrome, since FF also imported my Chrome bookmarks without acknowledgment.) I see that the old logins are still in logins.json, and logins.json appears to be valid JSON when opening with FF.

I tried ensuring that logins.json, key3.db, and key4.db had matching timestamps, but that didn't correct the problem. I tried replacing key3.db and logins.json with copies from a backup of the v52 profile (it has no key4.db--is key3.db no longer used?), but then zero logins appeared (why I think the ones that do appear may originate with Chrome). I tried exporting logins to CSV, but it only captured those 44. I can see the logins are in logins.json, but the passwords are hashed/obscured.

I have profile backups, but I don't find a way to import the logins. (If I had to make a wild guess, I'd say the upgrade might have ignored my key3.db that paired with my logins.json, and created a new key4.db full of Chrome logins instead.)

How might I recover my logins from either the in-use logins.json or from my profile backup?

Thank you!

I don't use "Clear history when Firefox closes". All cookies from other sites in exception list are saved. I added both https://mail.yahoo.com/ and https://www.yahoo.com/ to exceptions list but it didn't work. Then i tried with removing https://mail.yahoo.com/ from exceptions because in saved cookies list i see only yahoo.com, but again no effect. All permissions in Page Info for both mail.yahoo.com and yahoo.com are default.

When I open the Microsoft Teams URL in Firefox (https://teams.microsoft.com) it always goes to the login screen for a former employer. When I open the URL in Chrome or Edge it goes to the generic Teams site where I can participate as a guest. I am reasonably confident the connection is residue from when I used Firefox to participate in Teams meetings as an employee, but the connection is preventing me from participating in Teams meetings with potential new employers. I've deleted cookies for both the employer and the third-party two-factor authentication tool (OKTA), but I can't seem to kill it. The reason I think this is a Firefox issue rather than a Microsoft issue is that I never used Teams with Chrome or Edge and they do not have this spurious connection. Any suggestions? Thanks!

Comcast (Xfinity) requested that I change my webmail password. I have https://login.xfinity.com on the list of exceptions for cookies and site data to ALLOW. Regardless, Firefox doesn't allow me to do a password reset.

I used Safari to change the password. It worked.

Since I use most of the time Firefox, I wanted to go back and login into Comcast webmail using Firefox with the new password. It doesn't let me and just tells me to reset my password.

This used to work in the past. Something had to be changed since I last changed passwords for webmail in later versions of Firefox.

Please let me know know what to do to enable me to continue to use Firefox for webmail. I have version 115.5. Thanks.

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.

Is there a setting or add-on for firefox (Windows) that will block tracking pixels? My email client hi-lites when present and as I understand they are incorporated within images so I dont down load attached images to reduce them. On their pro version they allow blocking of these pixels. Unlike cookies there doesn't seem to be an option on reception to opt out. I'm not fully clear what harm they do or whether they are session use only and delete on power off. I would rather not recieve them atall. Companies when challenged smokescreen and refer to cookies rather than pixels or bang on about their companys integrity.

Thanks for your help

Hi all.

I use Firefox 120.0.1 with the setting "Delete cookies and site data when Firefox is closed" to clear said data when closing Firefox. I have also set an exception for a few websites, so they should save cookies and data. However, this does not work as intended. After closing and reopening Firefox, both cookies and data are gone from these websites. I have looked for a solution in older forum entries, and it was recommended to adjust the history settings. It seems that checking the box at "Delete cookies and site data when Firefox is closed" automatically sets the history settings to what can be seen in the attached screenshot. Altering these automatic settings unchecks the box above. Is this issue related to the website or is there a way to solve it?

Is there a way to transfer all my log ins and their words from my desktop Mac to my new lap top Mac Air. I need to do it possible my a flash drive since the first time I did it by migration and overloaded the lap top with all the stuff on the desk top. After lots of work to delete everything and reinstall the OS I did it by the flash drive. But I don't have all my logins and their passwords on the lap top.

Has the Autofill Forms option been removed from the latest version of Firefox? I get the opportunity to autofill credit cards but the Forms section seems to have vanished. Am I missing something? Thanks.

Today, after browsing about whether or not I should continue using Firefox as my password manager, I decided to mitigate the most important security flaw in browser based password managers, by setting up a Primary Password. I choose to use an easy to remember 8 word long passphrase as my Primary Password. I noted down the passphrase in my diary. Due to problem while loading YouTube, I decided to restart Firefox by going to about:profiles and selecting "restart normally". This issue where Firefox starts to struggle connecting to internet is a relatively common occurrence on my Firefox install, and restarting Firefox fixes the issue. When Firefox restarted, I was prompted to enter the primary password. I confidently entered my passphrase, but it was rejected. I tried to typing to it more carefully several times. I got my diary and checked it to make sure I was entering the passphrase correctly. Following troubleshooting steps on a similar thread, I restarted firefox, no luck. I than rebooted my computer, issue persisted. I decided to restart Firefox with extensions disabled, and also in troubleshooting mode. Firefox still rejects my passphrase. I have my Firefox account synchronized with two Android phones. Will reinstalling Firefox and syncing with my Firefox account solve the problem? In a similar troubleshooting thread, renaming key4.db and logins.json is suggested. However, it has not been explained very clearly. My logins.json file was modified an hour before disaster, even though I had made no changes to any of my logins or the master password. Is my logins.json corrupted causing the issue? I will like to point out a design flaw in Firefox which might have caused the issue. I usually want to see what I am typing when I am entering an encryption password. This is to make sure that I don't mistype something. However, in Firefox Primary Password configuration window, there is not option to see what you are typing. Firefox relies on low probability of typing the wrong password twice. I don't think devs should be so worried about shoulder attacks to not even allow users option to view what they typing. My case might be that low probability situation where I made the same mistake while typing the passphrase twice.

Firefox was working well on HTTP websites until a few days ago, but now HTTPS-Only Mode seems to be permanent. Despite changing settings to 'Don’t enable HTTPS-Only Mode', when HTTP sites are selected I get the same message as for 'HTTPS-Only Mode'. Also, if I select 'Enable HTTPS-Only Mode in all windows' and add exceptions, I get the same result.

Firefox recently started banking protection when it thinks I am accessing a bank Web site. Settings has no information about it. How can I exempt a particular site from banking protection?

Firefox is notoriously adept when it comes to browser/user protection, (THANK YOU!!!!!!!!). Are there any plans to include protection against homograph/homoglyph attacks please? I think the simplest way would be to just search the URL for any characters that are not part of the current/usual typeset?
