Diễn đàn hỗ trợ Firefox

I'm about to lose my mind on this. I have searched long and short where this would be hidden at in the settings and I can't find it. Anything I search for just gives me basic troubleshooting for autocomplete in the search bar.

First, Firefox has 2 twitter logins successfully stored in the password vault. When I go to Twitter the only suggestion for the login is "tulsa" and I have no idea where it's getting this. It will not auto fill in either of the 2 stored emails, not even if you begin typing them. I have to type them in manually and then when I submit it, the password is automatically typed into the next page.

Highlighting "tulsa" and not clicking or hitting enter and using the delete key does nothing.

This is really, really driving me nuts. Please help me.

The message about the "Browser being managed by your organization" that shows up in Firefox settings, is new. I've been using Linux mint with Firefox for over a year on my own personal laptop and this message just showed up in my Firefox settings kind of out of the blue.. Can it be related to version 100? I was just trying to do something online. totally unrelated to the Firefox settings, and now I've spent a considerable amount of time trying to get rid of this policy. I tried to set the AppUpdate policy to true, but it still will not allow me to check for updates in the settings, or if I go under help, about. I do not use the laptop often, so this is the first time I've been unable to check for updates, and I would prefer not to have an enterprise security policy running on my personal laptop. I do not know how it came to be on the laptop but any help removing, or resetting the controls would be greatly appreciated.

This isn't a question about the "Multi-Account Containers" addons, I am pretty sure that there was a section called "Container tabs" in the privacy and security settings, and I could use containers without installing an addon some days ago.

I can still access by directly viewing this address

about:preferences#containers

But I can't find it in the settings, and this feature does no longer work.

So I went to read recent release notes from Firefox 100 to 101.0.1, but I didn't find any notes to say this feature has been disabled. Could this be an unexpected result of an update?

Is it possible to turn off EVERY signle certificate check/verification in firefox?

1. "Error code: SEC_ERROR_BAD_SIGNATURE"
2. "Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT"
3. "Bulleted list itemMOZILLA_PKIX_ERROR_MITM_DETECTED"
4. "SSL_ERROR_BAD_CERT_DOMAIN"
5. "SEC_ERROR_UNKNOWN_ISSUER"
6. "etc etc... EVERY single certificate check!"

In the past it was really easy just start with "--ignore-certificate-errors". Now it's like moon landing, all options are hidden or have under a hundrred layer option list. Anything in the "about:config" ? browser.ssl_override_behavior 1 security.ssl.enable_ocsp_stapling false

(Please do NOT comment its unsafe and other things, that's not what I'm looking for)

I have a website stored in the popup exceptions. Yet every time I go to that website, Firefox blocks the popup, despite the fact that the URL/URI stored in the settings is EXACTLY the same as the URL/URI of the website being visited.

I then have to press 'allow' every time. Is there any workaround for this please ?

Also, I used to be able to download a PDF from sites directly, but now it goes to view the PDF and then I have to use the 'download' button. Surely there is a fix for this ?

Firefox 101.0.1 (64-bit) on Kubuntu

I have two user accounts on my laptop. I recently changed the password for one account and I'm now locked out. All my data is in this account. I don't have any back-up keys etc. I have tried changing my Windows password, but this doesn't seem to work. Is there any way of finding my previous password, or re-setting my current one without losing my data?

Hi, under Settings/Privacy/Cookies and Site Data/Manage data we can see site per site - how many cookies are currently existing - and how much storage

but I cannot understand what this "storage" includes. Let me explain : As soon as you open New York Times website (www.NYTimes.com), you can see there 12.4Mo of storage for nytimes.com. But if, thanks to Web Developer tools (Ctrl+Maj+I) I delete - all cookies relative to this website - and all cache storage - and all IndexedDB - and all Local Storage - and all Session storage and then close the tab opened on nytimes.com, and purge all cache, settings/manage data still says 10.6Mo for nytimes.com !!

This is obviously not only relative to nytimes.com, but most of the websites I browse have the same. I choose the example of nytimes.com to be very specific, and because it's a site anybody can browse, and the amount of "unknown storage" is very large.

What are these data, if they are not any of the above categories ? Where are they stored ? What are they useful to ?

Thanks in advance for your help !

Ver 100.0 Settings:Startup:Open previous windows and tabs is UNCHECKED. But every time I open Firefox, it opens the last site I had open before I closed it.

This worked before ver 100 and suddenly has stopped working with ver 100.

I even rebooted the computer (Win 10, 64-bit) and same behavior continues.

How can I enable the "ask to save logins and passwords" option? See the attachment. I do not use private mode and saving history is allowed. I can browse saved logins also, but I want to activate automatic infill of them. Firefox 102.0 64-bit

Hi there,

I would like the option "Delete cookies and site data when Firefox is closed" to be enabled, but it appears that Firefox is actively undoing this change. If I go into settings and check this box, it will appear to be successful and remain checked until that session is over, but if I close & restart, the box is always unchecked after restarting. Is this a bug in the build of Firefox I'm running (102), or is this behavior intended?

Thank you!

Where is the Export Login file saved? I am concerned about Warning message: Warning: Your passwords in the exported file will not be encrypted and will be in a readable form to anyone who can view this file. Do not upload online, email or share the exported file. Delete this file when finished. Export login data from Firefox

view this file. Do not upload online, email or share the exported file. Delete this file when finished.

When using 365 Outlook, I was sending message to Notes 365. It was working yesterday, but is failing today. I get the message noted below:

"We're sorry. We couldn't fetch your notebook. Please try again later. Details Error: The operation is insecure.Date: 2022-06-30T20:50:27.878ZSession ID: 0b74e553-3b1a-4c21-be65-b0f493b11951"

I was able to Edge to get it to work - but want to use Mozzilla...

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.

What can you do about it?

www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

When clicking advanced button there is no way to proceed:

Someone could be trying to impersonate the site and you should not continue.

Websites prove their identity via certificates. Firefox does not trust www.google.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

When I start a private window on FireFox, that same private window still has all the browsing history attached to my "normal" FireFox windows.

Ideally, I'd like to start Private Mode and have FireFox start from "zero": No access to past browsing data.

Is there a setting that allows for this?

Under Privacy and Security I have Firefox set to 'Delete cookies and site data when Firefox is closed' with no exceptions listed.

When I close and reopen Firefox, the cookies are correctly deleted, but the cache is not. I have to manually go into this setting to delete them. This also happens if I go to the menu bar setting of 'history/clear recent history'.

I want to keep my history of where I've been, but clear clear cookies and the cache every time close.

This doesn't seem like an unreasonable request for a browser that bills itself as being privacy oriented, but I don't see how to do this. Doing banking, I have to manually go into Privacy each time to get this done to clear the site.

From looking at previous answers to this question it seems the current way Firefox is designed this is "not a bug, but a feature".

Using Firefox 99.0 on a 2017 Imac.

When I join a Google Hangout and try to share my entire screen, Firefox always prompts me whether to share a window or the entire screen. I always want to share the entire screen. But when I enable the checkbox for "Remember this decision" I get this warning: Firefox can not allow permanent access to your screen.

Why does this happen? Is it because I'm on a unbuntu or is it specific to ubuntu Catalina?

Hi, I hope someone can help me. I am an author and sell my book through KDP Amazon. Firefox is my default browser but will not let me log in to KDP. No problem with other websites including Amazon.com When I open the KDP log in page it accepts my email address but the password button has a row of asterix right across the window. I cannot delete whatever is in there or change the password via the forgotten password route. Thus to sign in to KDP I have to use an alternate browser. With both Opera and Chrome I can sign in with no problems. I have added a screenshot of the KDP log in which illustrates the problem. Grateful for any solution to this irritation. Thanks, Paul
