Firefox Support Forum

1) When I played a video on Youtube with Firefox via my computer speakers, they worked flawlessly. 2) Then I plugged in my headphones via the headphones jack, there is no sound. 3) I went to Windows settings and checked the volume mixer and tested the sound, the headphones worked. 4) I opened Edge and played a video on Youtube, the headphones work flawlessly. 5) I played a video through my media player, the headphones work flawlessly.

So my conclusion is that it is Firefox that is broken.

I closed Firefox and restarted it and tried steps 1 to 5 above, still got the same results. Firefox did not play any sound over the headphones while all the others worked flawlessly.

I restarted my computer and tried the steps again and still got the same results.

I also deleted Cookies and Site data from Firefox settings and still no luck.

Any suggestions?

I went into about:config and changed the following values in order to widen the scrollbar:

css. scrollbar-width was true changed to false idget.non-native-theme.scrollbar.size.override was 0 changed to 100 widget.non-native-theme.enabled was true changed to false

Changing these values didn't widen my scrollbar. Without getting into coding, is there another way to make the scrollbar wider? (I changed them all back to the original settings when they didn't work.)

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.

Just lately I have been finding that, for a few websites, they are unusable because the screen looks extremely blurred. I have attached a screenshot. Compare this with what you see at ba.com.

I am wondering if this is caused by a new secure feature of FF which is incompatible with these few sites. Really, any suggestions would be welcome. Otherwise I have to use Edge..

Up until today, PDF files would open automatically in Adobe where I could look at the file and print it. Today, Firefox will only allow the file to be downloaded. This causes me grief, an extra step. One of the main reasons I use Firefox is for this feature. Is there a way to change settings so that PDF files will always open in Adobe?

Hi!

I can't scroll with the mouse wheel in Firefox. It works fine in other browsers and programs.

If I switch to Safe Mode, the scrolling wheel works. But if I switch back to normal mode, the wheel does not work again.

I tried to switch off and switch on "Use autoscrolling" and "Use smooth scrolling" settings, but it didn't help.

Unfortunately, "Refresh Firefox…" and reinstalling browser completely did not help.

I am at a loss, please help.

Occasionally, when I am watching a video on Youtube or Twitch, the video will glitch and cause the browser to go completely white. On Youtube, there will be a small visual glitch and on Twitch, the video will crash and need to be reloaded, but otherwise nothing else happens.

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!

Hello! Just installed Ubuntu 20.04.4 on my laptop and now find that I'm not able to watch some YouTube videos on Firefox 97. It seems mainly just live streams that I can't watch. When I go to one it shows "Your browser can't play this video...Learn more" in the video window. Clicking Learn More takes me to a page that doesn't explain what the problem is. Any idea what the fix might be? The same videos play just fine on other devices on my network. Any help would be greatly appreciated.

Since the last update to Firefox I have not been able to print using the system dialog. Only the new Firefox print screen comes up. How can I return to system printing dialog?

Also the ability to set print quality in the Firefox print screen does not exist. I can do copies, black or color, duplex printing, etc but not set the print quality like draft, text, photo, etc.

I also have many forms I've setup for printing and I can't access these.

Thanks, Pat

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.

What Happened To The PASTE Option, When You Are Composing A New Email In Outlook  ?

If You Copy Something, Then Right Click In The Message Section Of The Email, You Do Not Get The Drop Down Menu With PASTE As An Option.

You Only Get The PASTE Option When You Right Click Into The SUBJECT Line.

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.

Hi there, I am working on a site with Segment API and need to load their JS on my site for it to work. Whats happening is, I get the following error: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.segment.io/v1/p. (Reason: CORS request did not succeed). Status code: (null)."

The weird part is, it happens only in Firefox incognito mode. It works on Chrome, Edge, Opera.

I am wondering if this is by design or if it is a bug.

Firefox version 98.0 (64-bit).

I've tried everything to fix poor picture quality when streaming "third party" videos, e.g., YouTube. Colors are washed out; weird contrast; everything looks like it's coming through a haze. Streams from Netflix, Amazon look normal. And sorry, guys, the same third party streams from YouTube et al. look totally normal in the MS Outlook browser. Have tried all kinds of settings and rebooted as well. No change.

Please advise. This problem appears to be unique to Firefox.

Ubuntu is pushing snaps. However, I am not sure whether snap affects performance and other things. What is the advantage of snap for Firefox? Better security? Avoiding potential library conflicts? I don't think there is any conflict with the regular Firefox deb package. Moreover, the current snap Firefox gives me errors on Ubuntu 22.04. Gtk-Message: 15:49:48.484: Failed to load module "xapp-gtk3-module" Gtk-Message: 15:49:48.486: Failed to load module "appmenu-gtk-module" Gtk-Message: 15:49:49.153: Failed to load module "canberra-gtk-module"

Gtk-Message: 15:49:49.250: Failed to load module "canberra-gtk-module"

Howdy!

Whether I use Google or DuckDuckGo or FireFox, I get this message at the VitaCost.com website when searching for products. I can get to the website via http or https but this message stops me from ordering.

Access Denied You don't have permission to access "http://www.vitacost.com/Search.aspx?" on this server. Reference #18.94467b68.1660002130.7f6a9bb

Can any one give me a clue?

God Bless y'all for any help provided.
