Using Firefox version 102:

Open console tools and navigate to Network tab Right click on a POST request "Edit and Resend" is no longer an option? There is still the resend option Clicking resend allows you to edit the request, but unfortunately the "Content-Length" attribute is not automatically updated like it was with edit and resend, so all requests fail after being edited. This is because the Content-Length header indicates the size of the message body, in bytes, sent to the recipient. When you add or removes bytes in a JSON request for example, it doesn't get updated. The attribute can also not be manually set. How can I use version 102 to edit and resend requests the same way I used to?

Thank you.

The credit card autofill shows all the credit cards but when I click on any of them it does not autofill. Ive used this hundreds of times before and it worked fine. I never changed any settings and the autofill setting is on.

Please help!

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

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'd like to get rid of the status bar at the bottom left corner. I know it goes away and it seems impossible to remove. But is there any way to remove it? I add an image to show what I want to remove. Thanks in advance!

When I use firefox on my main display (1920x1080 144h 16:9) in full screen there is a noticeable white line in the bottom, not using full screen fixes it, but a pain in the ass to resize it all the time. I tried using the browser on my secondary smaller display (1920x1080 60h 16:9) and there is no white line. This seems to be a bug, how do i fix it?

I'm running Win10. When in FF browser the taskbar, which I have set to appear at the bottom of my screen, does not appear. I normally use "auto hide taskbar" setting in windows, and tried to turn this off to see if the taskbar would again appear while using FF. It did not. So, the taskbar seems lost when in FF. This has happened before, appears it is an intermittent issue. My windows10 is fully up to date as is my FF browser.

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.

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 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).

How to import passwords from a CVS file (such as create by Keeper password manager) into Firefox Version 101?

I looked at older questions (example: <<https://support.mozilla.org/en-US/questions/1329981 >>) but the solutions do not apply to the latest Firefox version.

Thank you in advance for your help

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.

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..

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.

A recent Firefox update has totally disrupted our ability to print from browser windows. There used to be a "Print Preview" button that allowed us to set things up the way we wanted them. That's now missing. As a result, stuff that used to cost us for ten pages now costs us for twenty pages. Also, when we print double-sided, the second side prints upside down.

This strikes me and my wife as a horrible development, and we would like to go back to the old version ASAP!
