I have a few add-ons installed in Firefox (85.0.1, 64-bit, under Windows 10, 1909), but when I open a Private Browsing window, I can no longer access them. True, they are still there and can be seen listed under Menu/Add-ons, but I don't see how to control them there, only enable or disable them.

If I want to use NoScript (for example) in a Private Browsing window, how do I set Firefox up to do that? -- jclarkw

I have been using Firefox for years now, but since an update a couple of months back, when I deploy a new internal site I receive an error stating that the "Secure Connection Failed" because of "Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL". There is a official workaround explaining how to bypass this issue, however it doesn't work. I have tested the same sites with Chrome, Edge, IE and it always works why is Firefox suddenly not working? Below are images of my local lab replicating the issue.

Hi.

When logged in to google (e.g., gmail) in one firefox tab, I am them auto-logged in to that same google account in any new tab or window I open. Is there a way to stop this?

I would like to be able to have one tab logged in to a google product (e.g., gmail, google calendar, youtube), but retain a "blank slate" when I open new tabs or windows, so that I can browse anonymously or log in to multiple different accounts (google or otherwise).

I have privacy badger and HTTPS everywhere installed in firefox, have set the browser to block all third party cookies, and to never remember history (high security settings across the board) . I tried enabling Multi-Account Containers, but I'm not sure how to use it and also suspect it is a more complicated functionality than I actually need.

I would imagine there has to be a way to "break" the connection between multiple open tabs or windows. Thanks!

My new computer is running Windows 11. I just tried to log on to my Vanguard account and the Logon button has no response. Using Microsoft Edge I had no problems logging on so the issue must be with Firefox security controls. I have turned off Ad Blocker Ultimate as well as made an exception for cookies from this site. What can I do to fix this?

Hi, I've noticed recently that on login to some website that because my account profile uses a gmail account the website is automatically logging me in.

I'm assuming the following is what is happening, I'd like to stop it and use my password manager to login, but this process the website is using is completely bypassing my configuration choices.

Should I assume this data is shared with Google? It must be right, they have sent an authentication request to google that my email on profile is valid and google knows the domain that made the request and the timestamp. Worse, this blocks me from using my own password manager or browser password manager and gives me no control over what is shared with google a 3rd party to website i have subscribed, are they not violating privacy terms by doing this? Is there a class action in progress somewhere?

Hello.

backed up an Ubuntu repository version of Mozilla firefox that was working and then did a new install of firefox from Mozilla repository.

Migrated bookmarks. Followed instructions to migrate passwords - copy over key4.db and logins.json to new install - but the new install does not prompt for passwords and when I look at the settings there are no saved passwords showing.

What's the preferred method to move over auto logins and passwords?

For a few days now, whenever I boot up my PC and I click on Firefox to start, instead of starting with the homepage it automatically starts with some sort of ad, usually to update Flash or something. I didn't screencap any of the addresses, but they're definitely random-looking ad addresses. And as far as I know I haven't installed or downloaded anything sketchy to cause this. Any way of remedying this?

I'm running Linux Mint 20 and have installed a free version of ProtonVPN. My firefox browser has a banner at the top stating "Your Browser is Being Managed by Your Organization". Not sure how this happened, but I am unable to update the browser because of this. I read some of the previous posts and they all appear to reference a Microsoft OS and Avast.

Hello SUMO Team!

  I always had this question but never really asked it. Why isn't DuckDuckGo or a more privacy based Search engine set as default? You even have to manually add Startpage and others... 

 It just hurts me how a privacy browser has the Google search engine as default after all, most people come to Firefox for privacy and Google is the opposite. Maybe one of the developers can change that?

Thank you so much for trying to help me and Stay Safe!

Hello,

recently I moved a website to the "Block Popups from this site" list.

Now I only have the option to generally block all pop-ups or to allow them in general.

Is there any way to get that yellow bar back, telling me, that something has blocked and allows me to select which Popup is to be allowed and which is declined?

Thank you!

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.

I was messing around with Privacy & Security settings. Under Cookies & Site Data, I checked Delete Cookies & Site Data when Firefox closes. I've decided I don't like it and want to uncheck it. But now it's greyed out and I can't find any way to change it back. It says I'm in permanent private browsing mode. There MUST be a way to change this back to how it was! What is it???

Firefox upgraded recently to 81.0.2. After the upgrade I can no longer connect to my bank’s web site. Firefox displays this failure message:

Secure Connection Failed An error occurred during a connection to xx.xxxxxxx.com The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

The bank’s customer-no-service help desk politely advised that their system is working, this is a Firefox problem, check the Firefox browser settings, use another browser.

I am not a browser security settings expert and do not want to be . . . I have no clue as to how to fix this . . . so what do I do?

Can I revert to the previous version of Firefox? How? Thanks.

First of this issue is atleast 4 years old. I found various different people having this problem. https://bugzilla.mozilla.org/show_bug.cgi?id=1432644 It should be a P5 not a P3. This official Mozilla article: https://support.mozilla.org/en-US/kb/add-trusted-websites-your-allow-list-firefox-focus Does NOT work.

I am trying to add an expection to tracking protection but there is no such option, as descriped at Bugzilla. In the adress bar i removed the tracking protection for a website. But it was NOT added to the exception list. I dont allow 3rd party cookies and auto delete cookies when closing Fox. I think that is the reason why it's not working, if this is the case it's a bug.

What i actually tried to do, using dark-theme from duckduckgo permanently. Because as right now, i must change the theme every single time i reopen Firefox. This is Bull**** honestly. Even when i add duckduckgo as an addon, it does not save the dark theme!
