Let's imagine that I'm trying to access a server on port 80, let's call it http://example.com:80 . I'd like to see if that site is actually active. When I try and do that Firefox instead goes to https://example.com:443 . In my example, that's actually a completely different site that I do not want to access (for completeness port 80 is used for certificate renewal of a whole bunch of different names that are all set up on other ports, of which 443 is one).

In both a regular Firefox browsing window and in a private browsing window, Firefox decides to access https://example.com:443 instead of http://example.com:80 , despite me explicitly typing "http://example.com:80" in the URL bar.

How do I prevent Firefox from doing this when I explicitly request an http site?

hi i have a question about recaptcha. it semes to apere on my website for no reson. i have no recaptcha active or something . how is this hapent? is it from my website or from the browser?

Lately I have difficulties logging-in to my two different e-mail providers. I have had them for years without any problems. Both don't let me log-in anymore. They want me to deactivate my ad-blocker - but I do not have an ad blocker installed with Mozilla Firefox! There is no such sign on the upper right and in the themes there is none either. The data protection is on standard. Although I agree to cookies but this doesn't help at all. So: where is the problem and why all of a sudden? What can I do? thanks in advance for your help.

I am a developer.I want to know the source code location in Firefox that reject tracker cookies and the code location for obtaining the tracking protection list after installation

I don't know how to give permission for third party cookies. I'm completely lost. https://pennstate.service-now.com/sp?id=kb_a

Websites ask me to turn off my ad blocker but I don't have one that I can see. Also YouTube does not open on FIrefox, which is probably being caused by the same issue. Thank you for your help.

I look at porn on my Android phone. I use Private Browsing to do so. Why are my Private Browsing addresses appearing as Firefox Suggest results that appear outside of Private Browsing as well? And why does Pornhub show me a personalized home page when I'm using Private Browsing? None of these pages are in my browser history because I've only accessed them via Private Browsing. But these "features" sort of defeat the purpose of it don't you think?

I've just switched from Chrome to Firefox and never had this issue with Chrome.

(btw my browser is Firefox Nightly) Don't get me wrong, I love having vertical tabs. It's less busy than the horizontal tabs and I can look through my tabs more quickly. But, the way it's implemented sucks - It makes the layout of the webpage pop anytime I use it; there is no keyboard button attached to opening and closing the tab (I have to go through my horizontal bar to open my vertical bar); and recently my browser forgets the sidebar settings, meaning I have to re-check the "Hide tabs and sidebar" setting.

Bonus request Can the sidebar just go over the webpage (i.e. like the application menu) instead of squishing it? I'm ok with having some webpage features temporarily covered if it means I don't have to see the screen pop into a new rectangular shape every time I switch tabs.

please fix this ....

Back in November (2024) I began noticing an absorbent number of cookies in “Manage Cookies and Site Data” (MCSD). Considering I delete cookies with fair regularity daily, this is unusual. The amount that I am seeing now, is around 190 advertising/Tracking cookies even when I only visit one or two sites. If I remove them and recycle the page and return to MCSD they are all back in storage in only those few seconds. This process can go on forever. This occurs even when I disconnect from the internet. How is this possible, where are these companies storing this stuff on my computer and how do I remove them and/or stop them from self populating? I have a Dell 64 something, running windows 10 I have Ad Blocker and Privacy Badger, along with a few others that are not security based. See Attachments

Thanks
