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.

Hi support team,

Yesterday, I suddenly removed all logins and somehow my profile was synced to the cloud.

Fortunately, I still keep all login files (json and key db files), I tried to recovery all my logins, it was successfully.

But, right after that my profile was synced from the cloud to my machine then whole logins were clear.

So how can I overwrite my profile in the cloud so I can totally recovery my old logins?

Kindly help to give my some advice.

Thanks!

www.google.com. PR_END_OF_FILE_ERROR www.facebook.com. PR_END_OF_FILE_ERROR Hi, This occurred after a moment of power loss during a thunderstorm on my Lenovo desktop. All my other sites as far as i can tell are ok. I used Edge and was able to access FB and Google on Desktop] i checked and the current version of firefox is installed on desktop

even weirder, i can access both google and FB on my laptop with firefox. I've tried syncing the two with having bookmarks etc. i can sync from laptop to desktop but not vise versa.

i thought I'd uninstall and reinstall firefox but i don't want to lose any info esp my Bookmarks on the Desktop hence why i was trying to sync the two.

My desktop is older, maybe 5-6 years, my laptop is 1 year old. Dunno if this matters. thanks, Jan

My new Windows 11 laptop forces me to use the "Mail" app to forward links by email using the "email a link to this page" utility feature in the Firefox toolbar Prior to this, my old laptop would just use Outlook which was quicker/better.

The multi-step method using Mail was cumbersome so in trying to designate Outlook as the sending vehicle over Mail, I designated a non-performing solution which is now preventing me from emailing links (and captured webpage info) at all. I would like to migrate back to Mail or find the correct choice for Outlook but the "email a link to this page" in the Firefox toolbar does not work now as a result of my poor choice.

Anyone know how to fix this? I have "restored factory defaults" and other on the toolbar features but does not help. This was apparently an unrevocable choice.

My problem is small, but it is this: every time I access a google page, my spouse's account is automatically logged in. Every time I have to switch account to mine. Is there something I can do in settings to make firefox ask me or my spouse which one of us is trying to log in? I don't see where in settings I might do that.

Firefox update required me to restart Firefox. I was unable to save a bunch of work I had done in a particular tab because Firefox seems to have refused to connect to the site I was working at until I update. THAT SUCKS!

This is a recent change -- the desktop browser didn't do this until a few weeks ago. It now plays slideshows automatically. This feature is called Auto-Rotation, but it has nothing to do with rotating the display on a phone or tablet (although that feature has the same name). This feature automatically rotates among the slides in a slideshow. It's incredibly annoying, especially since I typically forget its on (or don't realize I'm looking at a slideshow) and it changes to the 2nd slide just as I have begun reading the 1st. I then have to turn Auto-Rotation off and go back to the 1st slide to continue. When I remember, I have to hurry to turn Auto-Rotation off before it moves to the 2nd slide. Is there any way to turn this off? I can't find one by looking through Settings, and there's nothing on this subject in Help, that I can find. For what it's worth, whoever thought this was a good idea was wrong, but if there's a way to change so it's not the default, I'll be content.

All of a sudden on my Google search page there are "tiles" underneath, and no way I can figure out to get rid of them. There are boxes for weather, "what to watch", "trending", etc. I HATE them!! I've attached a screenshot. And, going into settings for Google leads me nowhere... Feel like this is a Firefox thing.

Any idea how to make my Google page (I used it as homepage) clean again??

Hello,

I have issue in firefox for URL not update. I have describe details scenario in below.

Ref Url: https://new.axilthemes.com/demo/react/blogar/post-list

Step:-1: Visit Mentioned above URL.

Step-2: Change Page from Navbar Page menu and change any one.

Above two step no any issue. Step-3: Follow again Step-1; Step-4: Disturbed URL like this ( https://new.axilthemes.com/demo/react/blogar/post-list1111111) but make sure after URL change do not page refresh. Step-5: Now you can change Page from Navbar Page menu and change any one. Observe Behavior your page changed but URL not refresh and this is only happened only firefox browser.

For the past 8-10 days, every time I try to log-on to: https://selfservice.telkom.co.za/rococo/public/content/interstitial I click "Login" under the Mobile & Home heading and I receive the following message returned.

Bad Request The request could not be understood by server due to malformed syntax.

I have used MS EDGE browser and do not get the same problem, it log's-on OK.

As such it seems that it is a Firefox problem.

When I update my website, It is unable to make the update public as the message that comes up tells me another website has embedded mine. How do I rectify this problem please?

I have been attempting to remove the block over my proxy settings. I have disabled VPN, removed Z-Scaler and even uninstalled and refreshed Firefox itself

Any help is welcome

Hi all,

Recently, my win 10 crashed and although I managed to recover some operative, I found to my horror that the desktop screen text size and contrast cannot be changed now. The current default setup is a real eye sorer, so I opened personalization settings but there is nothing on how to change this very theme, other than other posts suggesting entering the regedit system files. I am very reluctant to tinker with this given the Win10 application crashes. Running maintenance doesn´t do much. I notice that Firefox also has access to this very text size and font theme for web domains, but I am very wary again of tinkering an unknown. What the heck can one do, confidently without the system resetting itself? One thing is for sure, it seems Win10 home edition update 21H1/2 versions is basically treating users very badly, as if MS wants to ignore them. Bless us all when the embedded caption suggests "ready to update to Win11". I´m highly inclined to bin it.
