Firefox prefers IPv4 address in a dual-stack environment

Hi,

I'm using IPv4 as well as IPv6 addresses in my home network. But Firefox uses always the IPv4 connection when I open a website. When I open the same website in MS Edge, the IPv6 connection is used.

I've captured the network traffic during opening a website in Firefox, which is reachable over IPv4 and IPv6. First I see two DNS queries (A and AAAA) for the domain name. Both responses containing the correct IP address, and they arrive nearly at the same time at the client. Next I can see the TCP handshake. But it's send between the IPv4 address only. No IPv6 connection was attempted.

When I run the IPv6 test at https://test-ipv6.com, the IPv6 resuls are nearly fine. Only the web browser test says "Your browser has real working IPv6 address - but is avoiding using it."

When I run the same test in MS Edge, all tests are fine.

So it seems that this is not a OS or network issue. It affects Firefox only.

What I've already tried:

  • Disabled all extensions
  • Created a new profile
  • Used the IPv6 address of the website instead of the FQDN -> Works fine.
  • Checked DNS cache of Firefox (about:networking). It contains the IPv4 and IPv6 addresses of the requested websites

I guess that Firefox prefers the A record for some reason. But I've no idea why. Has anybody an idea what could causing this?

Thanks.

Recently if I browse pages with maths forumulas they do not display coorectly, instead the underlying Tex or LateX code is shown.

I have several computers and I use Firefox on all of them, but curiously this problem does not happen on all of them, some show formulae correctly.

The image attached shows an example at Wikipedia - Lagrange point . The upper portion is Chrome and displays correctly, the lower portion is Firefox where the formyuals do not display correctly.

This is only started recently. Previously I had no issues with formulas displaying on any pf my computers, for many years.

Saw older replies here, but I don't have the technical expertise to understand them.

The 3D function in Google maps doesn't exist. The item to click on is no longer there. Is there a work-around or do I have to use Chrome now.

(It seems with each update I automatically get, I lose a function. I'd like to get a link to a Firefox version from at least 6 months ago.)

For the 2 weeks or so, I've been having an intermittent problem connecting to any Google services (Gmail, google.com, Google Calendar, Youtube). In gmail, it tells me that I'm offline or "Oops, error getting emails". If I browse to www.google.com, I just get a blank screen.

This seems to have coincided approximately with the release of Firefox 100, but I'm not totally sure it's related. If I clear all cookies and cache, that seems to resolve the problem temporarily, but it comes back. If I open a Private window or another container, that also seems to resolve the problem temporarily, but it comes back.

Other browsers work with no problem.

If I open a new container, it will work for a while, but eventually stop connecting. This doesn't happen with other websites. Only Google related websites.

I have tried doing a Firefox refresh, but that didn't resolve the problem.

After reading up on procedures (but failing to follow links), I decided to completely delete all my passwords. Let me back up a minute, last week I downloaded the .csv file of my passwords, because after 10 or 12 years, I needed to clean them up. I had 486 saved passwords, out of which I deleted all but 123. I did not want to try that in the browser, actually I did, but after about 20 I gave up because I realized how long it would take.

So anyway, I got ready to finish up, and I deleted my browser copy, then tried to upload the corrected copy. However every time I get an error "Something went wrong try again". So as my plan was, I deleted my Chrome passwords (they should be the same), then uploaded the corrected copy. It said "Upload successful" or somethiing like that, I waited five minutes, for Chrome to finish syncing and all that, then tried to import from Chrome, it imported 3 passwords.

But now, here's the big problem, I follow the directions I have found in this site, but once I click the hamburger, the next link does not exist. When I go another way, none of the links exist. I have searched all over the settings pages, and nowhere is there the option to upload a .csv file, I can import from another browser all day, but not upload. So what's going on?

For the past year or so i have run into certain fields that will not accept a paste, whether by right click or Ctrl-v, and the behavior is consistent every time i try on that specific website. For example, a payment section of our utilities where though i can Ctrl-v my routing number (also it can be filled by what i can describe as a saved autofill - when you click in the field and the entry appears just below), but i can not paste my account number into the account space by either method (right click or Ctrl-v - nor does anything show below the field when one clicks in it).

I have always presumed that this is an intended behavior by whomever coded the webpage for security, but i just plain old find it annoying. Any chance i am correct in that it is a coding option these days, and if so, is there any way to break it?

Thank you!

Not sure where this fits in so I started here. I have been running firefox for a very long time. For my home page, I am using Protopage. I have my google calendar as one of the widgets on the page. I have it set up correctly. It was showing up yesterday. Now today it is not showing. I am getting this error:

Firefox Can’t Open This Page

To protect your security, accounts.google.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

I have not made any changes to Protopage or Firefox.

Got any ideas what has changed? What I need to fix to get it working again?
