This is Firefox 82.0 (64-bit) for Apple Macintosh. No matter what I do, i cannot get Firefox browser to NOT STORE cookies, site data, and cache. I exit the browser, start the browser back up and cookies, site data, and cache are ALWAYS still there n matter what my privacy settings are. My expectation is that I want Firefox to AUTOMATICALLY ''''NEVER'''' STORE cookies, site data, and cache. I also want FireFox to AUTOMATICALLY ALWAYS START in private browsing mode.

What settings do I change in order to NEVER have cookies, site data, and cache ever stored and to always automatically start my browser session in Private mode?

The settings as displayed in my attachment do not work and have never worked.

Is there a solution to this?

Hi, I am seeking a job and had a number of important tabs open when I had to restart my browser. Unfortunately, it was set to clear history on restart. Is there any way, on a windows10 pc, to recover them? Are they stored anywhere?

I have added Firefox to my firewall settings but am still getting the attached message all of a sudden when trying to access a website link through a Facebook post. Just started yesterday.

My phone is corrupted and Google knows it and ain't doing shit I'm not even the administrator. My email is set to we're i can only get certain things settings get changed.App that i delete or Uninstall come back.. All kinds of things 3 berizon phones later still there.. Help please.. Dont email with anything i should do they will shut it down.. emIl me i will go back here.

I have been using Firefox for a while. And then I had a different customer laptop which did not have one and I could not install anything. So I used Chrome. Now with a new laptop when I try to import the settings into Firefox, there are multiple duplicate entries found.

Is there an automated way to run through the same and clean it up?

Just received a supposed Firefox Update Marked "Important Firefox update available. Click "Install" to continue" Yet when I click the Install I get a Warning " You are attempting to install an add-on from 'performoverlyoriginalapplication.icu. Make sure you trust this site before continuing" Is this a legitimate Firefox update, and IF IT IS - why do I get that warning from Firefox. I do NOT know, so therefore can NOT "trust" performoverlyoriginalapplication.icu. Can someone who knows this subject better PLEASE advise whethere this is a legitimate update for Firefox and can they be trusted. Also IF that is the caes why does Firefox send me a "warning"???? Thanks for your help.

I keep getting a message to update Mozilla Thunderbird; and yet if I do, Thunderbird totally breaks. I don't dare update it and would like it to stop popping up the message. Can I do that?

How does it break?

When I update, it no longer allows me to use the "self-signed certificate" for MY OWN SERVER! I have tried every single possible way of manually installing the certificate; but it will not allow it. 68.8 allows it just fine with a message that pops up basically saying "do you really trust so and so is so and so" [with because it is my own server, that is asking, "do you trust that you are yourself?" And, yes, I do trust that I am myself, so I click permanently accept the certificate; and it just works. Newer versions stopped working that way; at one point (I believe it was 68.10 or 68.11) I was still able to manually install the certificate; but even that stopped working.

To put for a very apt analogy. Let us say that Thunderbird is a bank for e-mail; it stores e-mail messages; and conducts transactions (deposits/downloads, withdrawals/server deletions, and check processing/connections to servers) with the account owner and those the account owner works with.

A self-signed certificate is literally the same as a person signing their own check and giving it to someone else. The bank is SUPPOSED to process that check; the drawing bank should validate the signature for sure, but the bank that the check is depositing in should have no say. [Thus I have no problem with a warning popping up saying -- do you validate this signature.]

But, can you imagine one day taking your paycheck to the bank and the bank saying "no we will not accept paychecks that aren't notarized." What is the process of notarizing a signature? It is having a third party (a trusted licensed notary public) verify that the person signing (whatever--in this case a bank check) is actually the person they say they are. That is literally what having a third party trusted root certificate signature and chain is doing; it is notarizing the signature on the security certificate.

While that may make sense for someone conducing business with someone that they do not know. It makes no sense for an employer to have to notarize the paychecks for his employees; especially when that is to the tune of several hundred dollars per year. Employees already know who their employer is; and already have established that trust.

Again, when I am providing e-mail only to employees on my company server; there is no reason at all that Thunderbird (which has nothing to do with my business; is simply only the bank account for e-mail transactions) should require me to pay extra money to establish trust that their employer is really their employer.

This is about setting up secure email movement using Thunderbird. My ISP (a small outfit in Canada I choose to support) suggests using SSL-POP (Secure POP3) and SSMTP (Secure SMTP) for better security, yet I don't find these options in the latest version of Thunderbird. At the same time, Thunderbird is warning me of the insecurity of EACH of the 2 options it offers - standard POP3 and IMAP. I use one device for email, live in and work from a rural area and don't always have good or any connectivity (by personal preference!) so IMAP is not my choice. Can someone tell me if TB offers SSL-POP? Or...? I have had real problems over the past couple of years with breaches of security, account breaches, identity theft, etc. and I do need a more secure option than the standard. At the same time I want to use an open source email client. I would be appreciative of any advice or wisdom here. Thanks!

Hello all,

I've read some bug reports and discussions about the JNLP files blocked in Firefox ( JNLP should be treated as executable , Should not treat JNLP files as Executables (revert bug 1392955) on ESR-68 , Improve usability for JNLP and other executables and JNLP should not be considered an executable extension ). All I'm understanding is it has been blocked since Firefox 67, then "allowed" back again, then blocked for security purposes in Firefox 78. To sum it up, the bug 1576762 is still open, JNLP are still blocked. Nowadays, it's not possible to directly launch a JNLP file, you've got to download it and run it thereafter. Am I right ?

Also, I've taken note of the Firefox ESR release "too late". I've installed the "mainstream" Firefox release on a server in order to be remotely used by end users (via a RDS server, only to browse a internal website, they can't browse the web). What are the results/differences/cons (except the extended support) ?

Thanks in advance for your replies. Jo.

I cant seem to be able to disable automatic updates. Firefox updates automaticly in background at work and then crashes my tab and all my work gets lost when it has to update. Its really annoying.

Iv tried searching for settings and using about:config, changin app.update.auto to false. It keeps updating anyway...

Once upon a time when trying to create a blank tab, I accidentally typed "about:blank/" and this command doesn't work if the backslash is there.

Now anytime I want to create a blank tab and I type "about:blank" it automatically includes the backslash.

Because this phrase/command doesn't show up in my search history, even after clearing all of my data, Firefox keeps "helpfully" popping that backslash into the field whenever I start to type the command.

How can I make Firefox forget I ever made this stupid typo?! (Would clearing "Site Preferences" and/or "Offline Web Site Data" work? I admit I haven't cleared those two things.)

... if I launch thunderbird it prompt for pwd : if I click on te "X" of the window (to abort pwd input) thunderbird close correctly, BUT, if I press "Cancel" button it opens the main window and so everyone can have a look at my emails !  ;-) ...

Thanks, Walter

Using Toad-Hall instructions of 8/27/20, I went to the incoming server setting and changed it from "Normal Password" to "OAuth2" and did the same for outgoing server. I closed Thunderbird then opened it. When I opened it I did not get any prompt for access from Yahoo. I then tried to send an email to myself and to my Husband's yahoo email and I got a notice on both saying "the Imap server does not support the selected authentication method. Please change the authentication method in Account Settings Outgoing server SMTP". I changed it all back to "Normal Password" and everything is currently working fine. I am 74 years old and not a tecky person. Please explain in simple steps what I am supposed to do to enable me to continue to use Thunderbird. I have used Thunderbird for about 20 years and would hate to have it go away. Thank you for your response and I know this change is happening tomorrow. Claudia

Hello! I have a such problem. The thing is I need to use one Chinese site but when I try to log in the system changes my password automatically! I mean my password, for example, 123456789 and the system makes it "P:KJHGHVcfbvnm,nbhg. I can log in on other browser and on cell phone browser, but it`s very troublesome and almost impossible on Mozilla. What should I do? Help me, please! I need exactly Mozilla.

Firefox's Clear Data control allows you to clear both Cookies AND the Cache. This makes perfect sense, since both of these things can be used to identify/track people.

But from what I can tell, if you enable the option Delete cookies and site data when Firefox is closed, this doesn't clear the Cache, only Cookies?

In fact, the only way to clear the Cache at restart is to dig deep into the Clear history when Firefox closes settings, which few people would know to look in.

So, correct me if I'm wrong here, but isn't this giving users a false sense of security? They think all the Cookies will be deleted when they open Firefox, but actually the Cache is still there, allowing them to be easily identified?

Personally, I'm less concerned about cookies because they are opt-in (here in the UK). But as for being tracked via the cache, we have no say in that, so that's what I'm more concerned about.
