What is this window called? When this window started popping up a couple of months ago, I noticed a couple of odd things happening on a website I go to. It would not let me pay them. It would look like it was going to then a white screen would pop up ans say" if you see this window then you ...........". I then have to pay on the phone or chrome. I have whitelisted the site but still does it.

Hi there, in my settings in firefox: there is a website that refuses to go away from the "Manage Data" section of the "Cookies and Site Data" section of my Firefox settings. I will select to remove all of the cookies ever, and even when I refresh the settings page, or close and restart the App, or turn my computer off and on again, it is still there. Strange! I would like assistance with this.

of note, I've checked w/ third party extensions that manage cookies, and that website doesn't show up when I manage cookies via said extension.

I have MacOS Big Sur, 11.7.10. I have the latest version of Firefox.

Thank you!

Why does this pop up make. it past Firefox's blocker. Of course it's a scam also. Always pops up after midnight, I am a Windstream customer and they don't know anything about it but it looks official

Any way I can block them?

Hi, I want a website (Protonmail, my email client) to store persistent data. I have enabled it, but I also have all my browser security settings on Strict (also clearing browse data and cookies on each closing of the browser), so now when I have downloaded the data and I close and reopen my browser: it's all gone. I tried looking at making Protonmail an Exception, but that's only possible in relation to Tracking Protection. How to fix this?

Thank you in advance,

Kind regards,

How would one purge their cookies, search history, tab data while resetting/randomising identifiable information (for example if Firefox were to give each user a serial number or unique tag which it hands to webpages), all without resetting a users a user's browser settings, about:config & browser extensions downloaded (and extension settings). I am using Debian GNU/Linux, so bear in mind that I will be using the most stable version of Firefox on the Debian repos, not the newest version. I do not have a command line phobia, I am willing to do a lot of initial setup & run a specific command every time I launch the browser, even if said command is long. My current system involves rm -rfing the profile on a browser, but this is not optimal because it removes settings & extensions.

Thank you verry much for your assistance, I know this is a large undertaking and it a little overboard on the privacy and security front.

I just clicked on a banner to provide info

https://mzl.la/contribsurvey-2026 I didn't read the URL as I thought Mozilla would use a third party

Then when I finished the questionnaire, having provide my email address I saw another third party domain was in the chain.

https://survey.alchemer.com/s3/8925524/Mozilla-Contributor-Survey-2026

So I am unhappy that two 'strange' organisations have some of my personal details.

No fault of anyone, but me, I just got carried away in the security I felt using Mozilla

(

I hit the "Clear Private Session" icon, confirm, but then I have to go to:

Open Settings >

Privacy and Security >

Browsing Data >

Clear Browsing Data >

"Everything" (every check box has to be checked) >

Clear.

I have Firefox in permanent Private Browsing only, and Privacy and Security Settings are set to Strict / Do Not Fix any site problems.

Why does Firefox retain browsing site data even after I exit out of Fiirefox completely unles I do all of the above?
