Witam , Zakupiłem nowy komputer , zalogowałem się na swoje konto Firefox . Zrobiłem synchronizację , ale żadne dane się nie pobierają , ani zachowane zakładki oraz zapisane hasła. Chciałbym odzyskać te dane. Chodzi mi o dane z 14.11.2025 Dziękuje i pozdrawiam

I host a website, and don't want browsers (particularly Firefox) offering modified versions to others. Is there a header or something I can set webserver-side to disallow Firefox from offering the option?

This doesn't work:

add_header Cache-Control "no-store, no-transform, public" always;

Bitdefender security software Online Threat Prevention "Notifications" are blowing up stating the following: "firefox.exe attempted to establish a connection relying on an untrusted certificate to incoming.telemetry.mozilla.org"

The issue began approximately 17:00 UTC November 16, 2025

Please investigate & update the certificate or we may need to move to a different browser.

Firefox 145.0, (64 bit), ASUS laptop, Windows 11, <object>PDF. Embedded PDFs do not display in-page. Issue seems to only exist on this particular device. On same ISP pages display properly on other (HP) laptop and Tablet. I've disabled a few extensions and it displays properly.

My question: Which extension(s) will cause the issue?

After the most recent update, the Home Page does not show the minimize, maximize, and close buttons, when I first open the Firefox Browser. I can click task bar / show desktop and then maximize the Firefox Browser. Once I do that, the forementioned Home Page buttons appear. It seems that a fix is needed for this glitch.

Hi, Since the search open tabs function is part of the overflow button in a horizontal tab layout, when you switch to vertical tabs, you lose that search function. Is there a way to add it to my vertical tab layout? Thanks, Scott

When I try to "sign into" Firefox using Google Chrome, I see the following message: "This account is not active. Please contact an administrator if you believe this is an error." I do not know how to contact an administrator. I do not see this statement when I sign into Firefox using my Firefox browser. Maybe (I think) the issue is that I need to use my Firefox browser to "sign into" Firefox (and, not Google Chrome). Thank you for your comments about this.

On my previous laptop using Windows 11, a dialog box would open when I entered a username and password while online, asking if I wanted to save the username and password. On my brand new laptop, that dialog box does not come on screen. Id like to be able to store that info so I don't have to enter it each time.

Thanks!
