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.

After last update V104.0.2 fire fox will not allow me to access router to change settings message given, unable to connect, can I revert to previous version of firefox as always worked before update

I can't connect to my router using this same link I've always used: https://router.asus.com:8443/ I also tried: http://router.asus.com and: http://192.168.1.1/ Nothing has changed! I get a security error. See attachment. There is no "Proceed at your own risk" option. I've spent hours searching for a work around or fix. Nothing works! How in blue blazes am I supposed to connect to my ASUS Router's GUI. This is Windows 10, Firefox 104.0.2 (64-bit)

Hello,

I've changed the background color on the private tabs/windows with this CSS:

@-moz-document url(about:privatebrowsing){
 html.private{
  background-color: #2B2A33 !important;
  --in-content-page-color: gray !important;
}

I would like to make the "background-color" to be the same as the window background without hardcoding it, so it always match the theme, ie:

 background-color: <window.background> !important;

I would like to do the same with the background color of the search box in the private mode window, but I can't find the id.

Regards.

Hello,

I've just upgraded and almost done with the userchrome customizations but I need help with some little things.

Is there a way to remove the dotted frame in the history/bookmarks tree as seen in the attached picture.

Thanks.

I use Firefox to download, copy, and store WikiSpecies pictures.

Currently, my .../Documents/WikiSpecies/Animalia_Plantae_8 directory holds what it says are 90,876 items, totalling 11.5 GB. I have plenty of unused space in that directory (over 91 GB), so space is not an issue.

Lately, when I try to install a new picture, I keep getting a warning that the picture is already stored. This MAY be because I am running out of new pictures, but I can't tell.

Is there any capacity limit to a WikiSpecies directory?

Hi everyone,

lately I started experiencing a font-family-related issue. On certain websites the font-families/styles look broken. I tried troubleshooting the issue by myself without any luck. What I did so far was reset my Windows fonts to default, reinstall Firefox and look what font-families are loaded through the Inspect tool. If I opened the same web page in Chrome the font looks OK. Two websites the issue is most visible at - support.fiverr.com and gmail.com when someone replies to my e-mail.

Please find below a screenshot of what I mean

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

Hello All, I recently had to start up my brand new MacBook Pro up in "Safe Mode" to verify an unrelated problem. When I restarted my computer from safe mode, my Bookmarks were either gone completely or "empty" and I was apparently in a newer version of Firefox. I then trashed my Firefox application and tried to restore an older version via Time Machine and after I copy it to my Applications folder I get the message that I am trying to open an older version of firefox and then doesn't allow me to do that. When I followed the option to their extents, only the new version with NO bookmarks shows up.

How can I get my old bookmarks back?

Thanks bc

I want to know if there was any changes in recent tab cycling behavior? Now I need not press enter or click mouse button on one tab from list. Before there was instant tab changing after stop pressing keys (ctrl+tab). Greetings Kamil Tomicki

Once again Firefox adds a feature I don't want and can't disable. I want not to have a tab bar. They take up too much screen and get in the way. So I fond code that eliminates the tab bar unless there is more than one tab. Then the latest release addes the 'search tab' down arrow I neither want nor ever asked for and I can't get rid of it.

Why do you insist on doing this Mozilla? How do I turn this useless feature off?

This page just gives me a blank page.........and various other 'meta' pages/sites Facebook is fine Tried in Safe Mode but just the same.

When playing videos, specifically on YouTube, I can see some blocky/pixelated sections in video playback.

Issue is not present on Chromium-based browsers, I've tested in Vivaldi and Chrome. Both are using dav1d.

When AV1 is disabled through "about:config" the issue is gone, but then I face a stuttering problem.

This are my laptop's specs:

checking box within a Tab on yahoo mail will immediately open that entry and then freeze further operation until the screen is shut down. This happens on my wife's HP lap top i5 Pavilion 4.00 ram. ie: inbox tab will show a number of email - a dozen or so - followed by grey empty areas. The tab indicates 100+ total in inbox. Selecting one box opens the email but locks up any activity on that email & must be shut down to exit. The identical situation happens when I access my email on her machine. She is using Firefox 105.0.1 HOWEVER, on my machine, HP desktop AMD A8 8.00 Ram, both email addresses do not lock up, multiple boxes can be checked and work as expected. My desk top uses Firefox 104.4 This began happening within the past couple of weeks and I can not debug the situation. Any pointers ??

Dropa;

I can download an E-Trade brokerage statement from my DELL LAPTOP, Windows 10 and Firefox ((identical to my Desktop) whereby I can view the pages of the statement , however, from my DESKTOP I cannot download an E=Trade brokerage statement for me to view the pages of the statement.

Below is the address or link for downloading an E=Trade brokerage statement, on my screen, from my DELL LAPTOP, whereby the pages of the statement appear, This is the identical link / address that I copied from my DESKTOP, however the statement does not appear: "Download failed"

https://edoc.etrade.com/e/t/onlinedocs/doc?docType=stmt&docId=0

How may I correct not being able to download and E-Trade statement, to view on the screen (after which downloading to a file) on my DESKTOP ???

The uploaded image is not what I expected. There should be an image of my desktop and the text has somewhat background color which supposed to be transparent causing some texts to be cropped. I have Dark Reader extension turned-off since Facebook has it's own dark mode. How to fix this?

I'm on Firefox 104.0.2 Manjaro KDE Plasma 5.25.5.

I got this issue when tried to read some API document provided by a marketplace that i have project with. I tried on another browser and it shown normal, not a single text is overlapping. I've tried some suggestion on another topic to pick No Style on Page Style menu (View -> Page Style -> No Style) but it got more messed up and tried changing font size but still got no improvement. Helpp me pls~

Preamble: for most of the day I have Firefox open with several tabs. For a specific project I want Firefox open with one tab showing a specific webpage. At the same time I don't want to delete the existing tabs in the existing instance of Firefox - I want to keep them running in the background. Question: how do I create a desktop shortcut which opens a new single instance of Firefox with a single tab showing a specific URL ?
