Firefox Support Forum

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.

This has been happening for about a year now, I followed the guide and tried the troubleshoot mode and my tabs still crashes.

Can anyone help me read the crash reports and find the cause or common issue?

Here are the most recent crash reports I submitted.

We still use some Dell 13g servers equipped with idrac 8. When I'm trying to launch the virtual Console the window opens up but nothing shows. This used to work fine in previous versions of Firefox. I can't tell from which version it stopped but it's not long ago. Also idrac 9 console works fine in Firefox When trying to open console idrac 8 in Chrome it works fine Any idea what could be causing it? Any config switch to tweak?

A blank survey pops up in my homepage each time I open Firefox, I haven't filled it yet since I don't know what it entails and what it is about. There is no option to close it either, and it seems bugged as it isn't going away even after updating the version of Firefox, it is still present on 125.0.2 version. Kindly assist regarding the same. I have attached a picture of the same herewith.

I've been having problems with some websites not displaying content, others displaying error messages. So have been going through the Troubleshooting Mode and diagnostic process.

The cause is the MS CoPilot extension for Firefox.

Useful in other ways as I discovered several other extensions I don't need, hence have remained disabled.

Hi, i just got a new laptop (Asus Zephryus G16, 2560 x 1600 screen) and after installing Firefox there is a thin white border to the left of the screen when running in fit screen. This problem is not present when in a windowed mode or in F11 full screen.

I tried updating the Intel Arc drivers but this did not fix the problem. Changing to compatibility mode also did not fix te problem.

PS: in the uploaded screenshots it is quite dificult to see the white line(because the background is also white), but when the image is viewed in a new tab it is visible.

Thanks

Hello there i use wp.pl for mailing and after i stay on the page for too long the browser lags and it starts to use a lot of memory like from 4GB to even 8GB

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.

This has been happening to me with recent updates of Firefox, and I am very close to dumping a browser that I have used for years because of it. I go to load pages and it just sits there and spins and spins. In the time I take to open another browser like Chrome and copy and paste the exact same links into Chrome, where the download of the web page is practically instant. I go back to Firefox and it is still spinning and it is just ridiculous. I have no clue what would be causing this. After it finally loads a page, it seems fine on subsequent loads of pages.

I was playing on this free site called REPLAYPOKER, and it said I was blocked because of something called CLOUDFLAIR, can you tell me what this is please?

It totally blocked me and shut me out of the game

What should I do?

Is Cloudflair a virus? Should I go into the registry and remove it?

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?

Canvas is working on all other browsers normally, but when I try to login on firefox an error 403 message shows up at the two factor authentification step. I allowed popups already in this browser so that is not the issue.

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.

Hi, I'm hoping to find some help to address crashing that has been happening frequently. The most recent crash has a report ID: bp-47617fc8-55f9-4d32-8713-a4ce40240426 and this happened while in 'troubleshoot' mode.

This is the link to that report: https://crash-stats.mozilla.org/report/index/47617fc8-55f9-4d32-8713-a4ce40240426

Any help in finding a fix would be appreciated. Sincere thanks, V

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.

Suddenly on my PC the icon of Firefox turned white on both desktop and taskbar. And whenever I try to open Firefox, it says, "The file or directory is corrupted and unreadable." And I didn't make any changes myself. So far it was fine. Now what can/should I do?
