Under EXCEPTIONS I had to ALLOW certain websites. Then I decided to experiment and see what ALLOWED for SESSION really does.

Neither the entries for websites I allowed for a session were deleted from the list of exceptions, nor the cookies saved by these websites were deleted even when I closed the browser.

I do not see the difference in terms of what happens between selecting Allow vs. Allow for session.

Could someone who knows please explain or point me to the place that explains the difference and how this works?

Thanks.

When i click on the lock icon in the address bar, nothing happens (I would expect to see the encryption and certificate, but no widget opens). When I right-click into the page and select "View Page Info", "Security", "View Certificate", no certificate exists. Only generic info is shown (Servers+Authorities). Also an error is reported in the system log, confirming that no certificate exists: JavaScript error: chrome://browser/content/browser-siteIdentity.js, line 642: TypeError: issuerCert is undefined

Questions:

• Why does Firefox show the lock icon while no certificate exists?

• How does Firefox establish a secure connection without having a certificate? (From my understanding a certificate is needed for TLS to work.)

Version used: Firefox 78.12.0esr ('Mozilla/5.0 (X11; FreeBSD amd64; rv:78.0) Gecko/20100101 Firefox/78.0'), no add-ons or plugins.

I found some infos but I do not trust myself just deleting the files in question since they ared all over my system. The following I found per malwarebytes which found the pups every day up to now:

PUP.Optional.DefaultSearch is Malwarebytes’ detection name for a family of browser hijackers targeting Chrome, Firefox and Internet Explorer. Symptoms The browsers’ default search engine was changed to one that belonged to the threat-actors. I am german so probably I need your patience in helping me to clean my system resp. Mozilla.

Looking forward Ingrid

How can i hide my display/screen resolution from websites? I use Firefox in windowed mode not with my default screen size but websites know my default resolution. This can be used to identify my pc. I dont want that for privacy reasons like tracking and adverstising. How can i prevent this? I found many threads/posts about this in various forums/websites. They are talking about Tor Browser and that websites can identify you if using full-screen mode. But as i said, im using Firefox not Tor and while im using windowed-mode websites still know my default resoltion. I tested this on https://whoer.net/

Another question, how can i restore the default window size in Firefox?

Yesterday I went to my history to locate a prior site I had visited. There was only 1 site in history, which of course surprised me, and it was to CapitalOne.com/link accounts. This is my credit card company. I removed Firefox from my Macbook and then re-downloaded Firefox and installed. Nothing has changed. My settings are correct, meaning that I should be able to have sites visited in history, yet only the one site populates, and I've been to a lot of sites today....the credit card/link accounts site is the only site that is in history. You can imagine how nervous I am right now about doing anything on line. I sure hope that someone will help out here.

Hi. Starting somewhat recently, Firefox has been getting in the way of me downloading certain PDFs which I know to be fine but which it thinks are insecure or a security hazard. I'd like to disable this security "feature" permanently. How can I do this? Thanks!

As captured in the long thread "What's the difference between ALLOW and ALLOW for a SESSION?”, with a lot of handholding from jscher2000, I managed to set custom choices for privacy and security the way I wanted on my mac computer (blocking all cookies in all windows, with exceptions saved for ALLOW, ALLOW for SESSION and some for BLOCK). To accomplish this, required enabling deletion of cookies when Firefox closes.

My assumption based on information I got in the above mentioned thread, was that even when deletion of cookies is checked for when Firefox is closed, cookies for websites identified as exceptions with ALLOWED, are not deleted.

However, this is not what happens. A specific example is tripcheck.com, which stores custom itineraries for cameras in cookies. I setup quite a few of these custom itineraries and saved them and they were OK until I closed Firefox, when they were deleted, as the cookie was deleted. This website is setup as ALLOW in the Exceptions list.

As explained in the above mentioned thread:

"(2) Scenario Two

[X] Delete cookies and site data when Firefox is closed (checked)

Firefox shortens cookie expiration to session only unless the site has an ALLOW permission in the exceptions list. “.

I am more confused than ever, the settings do not appear to be working the way they are meant to work, not only for session cookies but also for what should be "permanent".

Am I doing something incorrectly or am I misunderstanding how setting should work?

If cookies of websites setup for ALLOW are deleted when Firefox is closed, the setting is defeating what I am trying to accomplish: saving cookies for websites that I use and save data in cookies (such as recognizing the computer, what’s needed for 2 step authentication, etc.).

Thanks.

If I try to update firefox browser (via "about") my system answers: It is not allowed because of administrator rules.

How can I overcome this barrier?

There is no administrator besides myself.

I dont want to only disable those addons/plugins, i want to completly delete them. When i klick manage, i can only enable, disabled, and change update settings. What reason is there those addons can't be deleted by default? Not everyone wants google...

-see attached screenshot

Currently on Firefox Version 85.0 (64-bit) using with Windows 10 Pro

Until recently (before Firefox updated versions) my cookies, cache and history, were automatically deleted on exit from Firefox with no problem. Now I can not delete them for some reason. Even when I try manually to "Clear Data" and also manually clear all History (all sub-menus checked to be cleared). When I restart and open an online newsletter, normally I have to sign in. I don NOT have passwords checked to be saved in FF options and never did. But now with the new version it just auto signs me into that website. I do NOT want my passwords saved/remembered, nor any of my other info, etc! It is really annoying and not secure if FF is now saving information we don't want it to! What is going on here? How do I resolve and get back the way I had it before the update? Please advise. Thanks in advance!

NOTE: I don't want to start from scratch by clearing out Firefox totally or messing with my profile. I have too much customization to start over from scratch. (That would be like asking somebody to reinstall Windows entirely when something minor goes haywire!)

hello there i have the following problem the company i work for has unistalled remotely firefox from my laptop, and i do not have any way to re-install it back i have managed in some way to obtain a copy of portable firefox on the same laptop since i was not informed about this process, i have not saved my password externally and unfortunately, i was not using a firefox profile

in few words: i do not have my passwords anymore

i have seen that in such folder: C:\Users\XXX\AppData\Roaming\Mozilla\Firefox

there are still saved three subfolders (one of them has the last modified date as 13th Sep, meaning today), therefore i think that my profile (and all relevant passwords) are still there somewhere

i would like to understand if and how i can import the passwords from the unistalled firefox in the portable firefox: i have already tried to copy those directories in: C:\Users\XXX\Desktop\FirefoxPortable\Data\profile

but no success, passwords are not importyed. please, i need help

thanks.

Hello.

Firefox prevents me from opening the following URL, citing Google Safe Browsing advisory:

https://github.com/sandboxie-plus/Sandboxie/releases

Google, however, denies having issued any recommendation to block.

I have noticed that the problem has something to do with my own profile. The problem doesn't appear under the following circumstances:

• I start Firefox in troubleshooting mode
• I start Firefox with a new profile

I tried manually disabling all my add-ons, but even with all of them disabled, I can still reproduce the problem.

Any idea what could be wrong with my setup?

Firefox Browser uprated to 92.0 today. Previously whilst browsing Ad's were showing; today I have no Ad's displayed but have not enabled an Ad Blocker on Firefox. A site I use extensively cannot now be properly viewed; I get a message to turn off Ad Blocker. I have set Enhanced Tracking Protection to 'Off' but am still unable to obtain full functionality, I am using standard Firefox Privacy settings otherwise. I am able to browse the site properly using MS Edge. I have deliberately refrained from using any AD Blocking on my part so as to ensure the site in question can be properly viewed. The only Firefox extension being used is Kaspersky Protection; I get the turn off Ad Blocker message both when Kaspersky Protection is on or off.

When I choose any other option then remember history. Ebay page does not display properly. Only way to get it working is to choose remember history.

Please fix it as I just don't like my browser to remember history

Hi,

I have been using Firefox sync for many years now. I just got a new computer and when I tried to connect with my account, I received a message saying Firefox has locked my account.

Would you please fix this asap? I use your browser to work and not having my account back would force me to switch to Chromium, which I don't want to. Please note my account and my email address are both legit. Thanks

I made a few changes to about:config. How can i save the about:config settings for a new Firefox installation? My bet is this is possible either with distribution-policies.json or with a HTML. I used Kali Linux, this operating system comes with a pre-configured Firefox installation. For example it uses a permanent darkmode with duckduckgo even while cookies are denied. It also comes with customs about:config settings like disabled telemetry.

Those are all the setting i changed and i would like to find out a permanent way to import them to Firefox, right after installaing the Browser. It's time consuming changing each setting manually after each install...

If you know any more settings that shuld be disabled, please let me know!

Hi all, I have an Apache site on Kubuntu 20.04 with a certificate signed by my private CA. I've added the root CA ceritificate in Firefox and in Chromium.

Firefox throws a SEC_ERROR_BAD_SIGNATURE error

Chromium accept the certificate as valid

What can I do?

Notes: the site url is "https://hdev.h.net" (with an internal IP address inside my lab)

Attached there are:

- the authority settings page
- the certification authority certificate as seen by Firefox
- the site certificate

Firefox version 82.0 Ubuntu Chromium version 86.0.4240.11

Hello, We run a website that uses a bookmarklet button which allows us to capture the current URL location and save it. This is placed on the Tool Bar where its easy for a user to use. Until now, its been working perfectly but with this latest update to FireFox we are seeing the pop-up blocking being activated with the yellow message bar at the top. Now this would be ok if we only had to allow the pop up once (by clicking allow site), but unfortunately the bookmarket button has to be able to work on all sites, which is the whole point of the button. So its impractical to keep allowing it every time its used. Disabling the pop-up blocker completely then works, but then the browser is open to other pop-ups. Is there any way to allow bookmarklets to display a pop up and not display a pop-up message? Without having to disable the entire pop-up functionality. Can the FF developers allow for user placed bookmarklets to not be pop-up blocked. Maybe an exception added for that. They are placed manually by the user so are allowed by the user only.

Thanks for reading. Paul.

I am trying to disable Firefox notifications whenever I take screenshots, and googling for solutions, I found the commonly suggested solution is to uncheck the "Pause notifications until Firefox restarts" box in Permissions:

How to turn off forever the "screenshot" splash notification

"shot Copied" window

This option is not available in my browser version; thus, I'm hoping there's a newer workaround for this.

Hi; hope all is well in your world!

I have a ProtonMail account. (It works fine, I recommend it!) Had it for years, but have not used it much. Looking into VPN and proton offers one, so trying to find out more, and so am now exploring the proton site quite a bit.

I can log into ProtonMail itself very easily; I get directed to my ProtonMail inbox. Cool so far. But clicking on 'help' takes me to ProtonMail Support, in a new tab. Not so cool, because I'm now not logged in. If I hit the 'LOG IN' button at the top of that page, I can log in (again) very easily. But it takes me back to my ProtonMail inbox! Same problem if I try to log in to the Protonmail Blog.

I've tried everything I can think of. I've checked through all the ProtonMail support articles (that claim they are 'step by step guide to find easily your answer'); I've investigated 'Common Login Problems', and none of the offered solutions apply (I'm not having a problem logging in; I'm having a problem logging in to something other than the inbox.) I've tried disabling browser extensions; checked the settings of Javascript, Session Storage, and Cookies; even tried using a different browser.

I think the answer to this conundrum is to configure Firefox -- just for proton -- so that instead of opening a new tab it opens the content in the same tab. But I've searched Firefox help, and have not been able to discover how to do that.

I fear I am slowly but surely going insane.

Please help!
