I am unable to get printing to work correctly using Firefox with Epson POS TM-T20 thermal printers we have a work.

We're currently running Firefox on Debian 12. I've tried both the ESR version that comes with the Debian repository and the latest Firefox as a flatpak.

When printing to the receipt printer, the only thing that is printed is the left-hand most part of the logo and a little part of the text and this occurs towards the right-hand side of the paper. I've changing all of the settings, resetting the settings for the print in about:config, but nothing seems to work.

I'd love to get this working so that staff could use Firefox. I'm attaching an image of what the print job looks like and a screenshot of what the print-preview shows.

I am running the latest updates to Windows 10 Pro x64. One of my monthly bills is paid at

1) https://e.synchronyfinancial.com/

which, in Brave, redirects to

2) https://lowes.syf.com/accounts/login

Inputting either link in Brave gets me to the finish line but the first link above fails in Firefox with the "Secure Connection Failed" message and dumps me at https://www.synchrony.com/accounts/. The second link does the same.

Is there any way to troubleshoot the problem?

I HAVE tried shutting-down Malwarebytes but the result was the same.

This is the only site on which I have encountered this issue. All that I can determine at the moment is that that certificate is from DigiCert and the expiration date is in 2025, i.e., this is not a Symantec cert.

DigiCert Global G2 TLS RSA SHA256 2020 CA1 Organization (O) DigiCert Inc Organizational Unit (OU) <Not Part Of Certificate> Issued On Wednesday, February 7, 2024 at 6:00:00 PM Expires On Tuesday, March 4, 2025 at 5:59:59 PM

I don't use Google Chrome browser nor do I use MS Edge. After using the Mosaic browser, I switched to Netscape Navigator, then to Mozilla, and, finally to Firefox. I am not looking forward to migrating to another browser. ;-)

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

I'm running Firefox 102.4.0 ESR (32 bit) on a Win-7 (32 bit) PC.

It works fine. I visit a LOT of websites, it works fine.

Until just now. I'm trying to bring up namecheap.com (a domain registrar) and I'm getting this message:

Secure Connection Failed An error occurred during a connection to www.namecheap.com. security library failure. Error code: SEC_ERROR_LIBRARY_FAILURE

I'm not given any option to alter any FF settings or to otherwise create an exception to "trust" this site to be able to access it.

I've read where changing security.pki.crlite_mode (currently 3) to something else (like 0) and I've tried that, and unless I have to close and restart FF for that to take effect (which I have not done) then that setting doesn't fix the issue.

What exactly is going on here? Why is only THAT SITE giving me problems?

For about 6 months now, I've been having a strange problem with Firefox leaving behind ghost entries on the Win 11 taskbar.

I have a laptop attached to a dock which is connected to multiple monitors. If I have a FF window open on one of those external monitors and disconnect from the dock, all the tabs that were open in that FF window will become ghost entries on the taskbar. (see attached image).

It doesn't matter if I close FF entirely, these entries remain until I restart the computer. If I click on one of them, it opens up a brand new, blank FF window.

Has anyone else experienced this or have any idea what might be going on? I tried doing some investigating a few weeks back and I remember finding something in the task manager about COM Surrogate that seemed connected, but I didn't get beyond that.

Since the update to version 125 Firefox on Windows 11 (all updates installed), when I open a new tab and start typing to the address bar WHILE the VPN to the office is active, Firefox locks up and can not be used anymore.

In taskmanager, there is no spike in memory or cpu usage visible. All I can do at this point is to kill Firefox via taskmanager.

I can enter anything in the address bar of an already open tab with an other website open, I can open new tab from the bookmarks, but I can not open a new tab and start typing in the address bar while the VPN is active.

Once I disable the VPN to the office, everything goes back to normal.

I never had this issue on a previous version of Firefox.

Any ideas whats causing this?

I’m using the official ShadowsocksX app to relay network connections through a Shadowsocks server, and Firefox seems to be having compatibility issues. The browser does not load pages when proxy settings are set to “auto-detect” or “use system:” I’m getting the “Unable to connect” error message. Manually setting the SOCKS host to 127.0.0.1:XXXXX does fix the problem, but that also means I have to switch back to “system” whenever I turn Shadowsocks off.

Neither Safari nor Chrome requires manual action to relay connections on the same computer.

On a different computer, I’m using the Outline client to connect to the same Shadowsocks instance. Firefox does not have issues with that.

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

When browsing with Firefox, scrolling with the up/down arrow keys intermittently causes the keyboard to be disabled. Trackpad and touchscreen still function, but keyboard becomes completely disabled, requiring a reboot.

This ONLY happens while browsing with Firefox browser. I cannot deliberately reproduce this, but it happens frequently - up to several times a day. It seems to be tied to multiple key hits on the down and/or up keys. This only happens in Firefox, not in any other apps, including Visual Studio.

This is a brand new HP laptop. HP support says that this is a Firefox support issue because it only happens on Firefox and no other programs or scenarios.

Can you please help me to identify, troubleshoot and resolve this issue? I am a software/database engineer but this is a little outside the scope of my knowledge. I should be able to conduct any tests or provide any needed feedback at a useful level with only a reasonable level of hand holding. I suspect that Firefox is somehow inhibiting or disrupting the keyboard driver.

Hello. Our organization is experiencing an issue where sound settings are not carrying over correctly to Firefox. Specifically, this is with speaker settings. In multiple calling platforms (tested in Genesys Cloud and Teams), we are not able to adjust the settings for the speaker that audio plays from. We can adjust the default microphone setting, but not the speaker setting. This is only occurring in Firefox (works fine in Edge and Chrome).

Additionally, we've tried adjusting the default audio settings by going to Windows > Sound settings > App volume and device preferences, and changing the settings specifically for Firefox on this page. This does not work. When we check Teams or Genesys Cloud, it seems like Firefox is just picking any default without a rhyme or reason.

Any assistance would be greatly appreciated.
