I added a secondary email address, but it doesn't display. After waiting several days, I tried adding again, but it wasn't accepted with the message email address already exists. It still doesn't display. I have reviewed the on-line instructions and followed them precisely. The instructions do not cover this issue.

Any suggestions or assistance appreciated.

I am trying to print some pages from within my Firefox browser which is updated daily.And no matter what settings I choose for page width, margins, orientation or scale/fit to page the pages print way to the right and half the information is not printed. This happens when I choose to print the whole pages as well as when I choose to print my selection. I went to the new about support page (which I hate as I cannot change settings like I used to be able to change them) and I cleared the printer settings as was suggested in the Firefox help section and that had no affect/effect on the printing issue. I have wasted half a ream of paper trying to figure out how to deal with this on my own and have just filled my trash receptacle! Any help with this issue would be greatly appreciated. And you could throw in (if you like) a tip on how to change settings in the new about: support/config pages) Thanks very very much!

I'm bringing a problem, but I'm also bringing a solution. At least the solution that worked for me.

There are at least a couple Mozilla threads on this, but they didn't solve my problem.

If you have no audio in YouTube, or some particular Firefox tab, go up to the specific tab that you're not getting audio in.

As you move the mouse to the Red play button which is YouTube's logo, if my fix is the right fix for your particular lack of sound, you will see it turn to a Muted speaker icon. Left-click that muted speaker so that it unmutes!

To reiterate, evidently Firefox has the ability to mute or not mute a single tab! Also, you may see the word MUTED in the area immediately below and to the right of the Red play button, helping you to know what's going on. The thing is, the Muted speaker icon ONLY appears if you've Mouse'd over it, which I think is suspect programming.

I regularly capture screenshots of pages at 1440 x 900 on a 5K iMac. When I paste these images somewhere they appear as 2880 x 1800.

I've tried messing around with the settings, but can't seem to find a way to make the final image 1440 x 900. Setting the DPR only seems to work if it's at 2. If it's at 1, the screen shot is the right dimension, but is missing 75% of the image.

Even though I'm on a HiDPI screen, I would love to be able to capture a 1440 x 900 screen and have the image actually end up being 1440 x 900. Is there a trick to this?

This probably seems like a silly gripe, but when copy-pasting text, say from a website into a Google Doc, I used to often paste it into the URL bar first, then copy it to paste into my Doc, because that was a quick easy way to remove formatting from the texts (hyperlinks, bold, etc.).

At some point relatively recently, this changed. Now when I paste a chunk of text into the URL bar and either cut or copy it from there, what I get when I paste it is just the URL of the page I'm on. The text I'd pasted into the URL bar might STILL BE THERE when I hit ctl+C and ctl+V but what gets pasted is the URL of the page that actually is nowhere to be seen. Is there a way around this or do I just have to take longer to remove formatting from pasted text now? Thank you for any info!

Firefox redirects my local virtual server website url to an external url

I am a web developer who makes websites on my local work station. I use XAMPP (Apache & PHP) on Windows. I edit my Windows hosts file to include server aliases like:

127.0.0.12 pierremarketinggroup

...and then I add a virtual server to the Apache httpd.conf file, so that when I type:

http://pierremarketinggroup/

...in my address bar, it will take me to the local website on my workstation hard drive.

This has been working for years on Firefox, but now, after upgrading to PHP 8 in XAMPP and some fiddling around, Firefox no longer respects the local domain, but instead will redirect me to

https://www.pierremarketinggroup.com

...which doesn't exist, yet.

Firefox does the same thing with all my local, virtual domains. Chrome, Edge, and other web browsers continue to work normally, so I know my Apache and Windows hosts settings are correct.

What I have tried: - Cleared content cache, restarted Firefox. Didn't fix the problem. - "Refresh" Firefox. I think this was a mistake, as I lost all my logins, but too late now. Even so, it didn't fix the problem. I type the local address into address bar, and Firefox doesn't read it, or doesn't look up the local domain, or I don't know what.

I used to be able to fix the problem by going to Privacy & Security -> Cookies and Site Data -> Clear Data -> check Cached Web Content -> Clear, and that would usually fix the problem. Now it doesn't fix the problem.

How do I force Firefox to look up the domain on my local machine, instead of redirecting me to an external (and usually unrelated) url?

On Linux, when running: sudo netstat -lnp

I get the following output: Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name udp 0 0 0.0.0.0:5353 0.0.0.0:* 2436/firefox

I see that Firefox listens on UDP port 5353 (mDNS). I do not like that, since the computer has public IP address. I tried to look for ways how to disable mDNS in Firefox, without any luck.

Please could anyone advise how to disable mDNS in Firefox?

Media keys are not working on Firefox though they're working just fine on Chrome. I can pause playing media in an active tab only with space. I'm unable to use the seek back, forward and pause buttons. It's kind of annoying that I have to open the background tab where the media is playing and pause it with space or my mouse when I could simply hit the pause button while working. I've tried disabling and re-enabling media.hardwaremediakeys.enabled in about:config but nothing happened :( Thanks.

- Restarting my laptop - Clearing the cache and cookies - Disabling hardware acceleration - Disabling Enhanced Tracking Protection - Running in Troubleshoot mode - Refreshing FF - Reinstalling FF (Currently running 93.0, 64bit)

Youtube buffers the video but won't actually play it. The same goes for Reddit.

I'm at a loss for what else to try.

I am a web developer who often writes websites on my own local computer. I use Apache web server, and using both the httpd.conf file and Windows' "hosts" file ( C:\Windows\System32\etc\hosts ) I can make an alias for 127.0.0.1, otherwise known as localhost. Because my name is greg, I can add a server name to my localhost, like http://greg/test.html.

This works pretty well, but sometimes when I add a new alias, like greg or gregory, Firefox doesn't pick up on it right away. I can go to http://greg/test.html in Chrome, and it goes to the local web page just fine. But if I try it in Firefox, it tries to redirect me to "http://www.greg.com". The usual fix is to go into Settings -> Privacy & Security -> Cookies and Site Data -> Clear Data -> Cached Web Content, then press CLEAR.

But this doesn't always work, and it seems like no matter what I clear, Firefox insists on not looking up my local server alias, but instead redirects me to https://www.greg.com.

How do I force Firefox to look for http://greg/ only on my local server?

Regrettably I got locked out of my Sync account due to losing my 2FA and recovery. Giving that to err is human and data losses happen, I had hoped that there would be an alternate method of resolution, even if it means that the account is deleted so that the end user can use their primary e-mail account.

Given that my account login is my e-mail address and my e-mail address is the equivalent of a company holding my name and address I assumed it would be possible to use an official request for data removal.

Unfortunately Mozilla will only remove your e-mail address from mailing lists and not from sync account servers. So, it would appear that once you lose your 2FA, Mozilla can retain your personal details forever, and there's nothing you can do about it. Essentially what I got back after waiting for a month was being removed from any e-mail subscriptions and a 'get stuffed we can't help you, here's a link that we know can't help you'. Pretty bad after waiting a month.

It certainly makes it very secure, I'll say that, but also very weird to have an e-mail address that is unusable for the next few thousand years. Essentially on a blacklist. Having moved to Firefox after Netscape Navigator it's a shame to be locked out or to even be able to delete the account so I can start again. Anyway, my account sync with Edge and Chrome on both my Kubuntu and Windows install work fine so it's not like I don't have a browser that won't sync.

If anyone does have a solution, I'll take it, but after a month of trying various methods I think my e-mail address is now useless for Firefox Sync, and thus Firefox is now useless to me and I'll have to use Edge and Chrome instead.
