Firefox Support Forum

Hello!

I recently decided to switch to Firefox Developer for personal choices and upon looking at certain sites that use custom fonts, a few of them break and show the default font (Times New Roman) in their places instead. I've tried many solutions to fix this such as adjusting the settings, downloading TrueType fonts, and even messing with the settings in about:config and still the text would not show up properly. For some strange reason, though, the font's themselves seem to be working on the regular version of Firefox but not the developers' edition. I will post examples of my problem below if that helps.

Thank you!

Copy/Paste not working- ASKED MANY TIMES AND ISSUE STILL PRESENT

when it comes to buying a new pc I will switch out to another browser, shame a good 12 years with FF.

Hey everyone, I need some help with a puzzling issue. I've noticed that a website (https://socialhubin.com/how-to-pause-instagram-reels-like-a-pro-uncovered/) I'm working on functions perfectly fine when I use Google Chrome, but when I try to access it using Mozilla Firefox, I encounter a '404 error' or sometimes the layout is broken with images displaying incorrectly. Can anyone shed some light on what might be causing this discrepancy? Your insights would be greatly appreciated!

For the past couple of months I have been getting the message www.bbc.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR when loading pages on www.bbc.com website. I have done a search on the internet and it seems this is a common problem with Firefox and does not affect othere browesers. I have done what was advice given online but it does not solve the problem. It is getting so bad I may have to start using one of the other browsers even though I prefare Firefox.

I hve discussede the matter with my banks IT-department, but they answer me that recently they have heard about the same problem concerning Firefox login and said that the problem have to be fixed by Mozilla/Firefox

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

When pausing/starting or moving video feedback volume changes to an fixed volume. Opening video player in youtube default volume is at 41%, I put in at 100% but when I pause it or change to another part of the video, the volume changes to the default again. It's not from OS because with chromium browsers doesn't happen (brave,steam chromium) and with librewolf happens. Wanted to publish a 10 sec video showing the error, because I don't know how to show it with photos.

I'm running the latest version of Firefox (126.0) on an iMac, OS 14.4.1. Starting a couple days ago, i was no longer to (consistently) minimize Firefox browser windows by double-clicking on the browser window title bar. I'm able to minimize the window INCONSISTENTLY and only very infrequently via double-clicking, but with no obvious pattern. This problem only occurs with Firefox. I have no problem minimizing any other browser or application windows.

My Mac OS settings are always set to "Double-click a window's title bar to minimize."

I can minimize via Command-M, but i prefer to double click. I vaguely remember this occurring on another iMac of mine some years ago, but don't remember if i found a fix, or if it went away on its own.

Thanks for any help! dan carlson Belmont, CA

A recent set of system updates appears to have made most website videos not play in Firefox.

When I inspect the Developer Tools - > Console tab the most detail Firefox gives are an error line similar to: Media resource URL could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Internet searches for the error name and error hex do not appear yield any applicable troubleshooting, nor any methods of collecting additional problem data.

How can I obtain more detail on where the error is happening and how Firefox might be interacting with other packages present on my system?

Arch Linux has some older ffmpeg-compat packages, but those don't appear to match any of the web results, in that they're even older versions of ffmpeg.

yay -Ss ffmpeg-compat aur/ffmpeg-compat-55 2.3.6-4 (+24 0.00)

   Compatibility package for ffmpeg to provide versions 55 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

aur/ffmpeg-compat-54 1.2.12-4 (+87 0.00)

   Compatibility package for ffmpeg to provide versions 54 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

For some reason, the bullets used to hide a password are not rendered properly in Firefox. As shown by the first uploaded image, they are displayed as big white-filled circles.

This problem does not occur on chromium-based browsers, as shown by the second uploaded image, which is a screenshot taken from chromium, on the exact same session.

I have already done the following:

• verified that the "Allow pages to choose their own fonts, instead of your selections above" box is checked in my preferences. I have also tried disabling and re-enabling this option
• launched FF in troubleshoot mode to disable extensions and hardware acceleration
• verified that gfx.downloadable_fonts.enabled is set true in my about:config

All of these attempts however failed to solve the problem.

This problem is occurring on a fresh install of a Linux distro, so I first thought that I might be missing some fonts, but the problem might lie somewhere else since the symbols are properly displayed in chromium-based browsers.

A marquee markdown is not showing in every firefox version I tried (Normal, nightly and dev), none of those versions was showing this markdown. So I'm writing about that. I know it's new, but I think it's very good, and useful markdown.

Suddenly my Firefox browser won't open popular websites, such as Schwab, Facebook and Wells Fargo. It displays an error message that the site uses Java, and that I need to enable javascript. When I check in Settings, javascript is already enabled. I tried restarting and reinstalling without success. When I use the Chrome browser the sites work normally.

I have used a free Hit Counter for many years that I got from https://www.freecounterstat.com/

I have 3 such counters and have stopped working in the latest version of Firefox on my desktop. They work with Firefox on my iPad and Android phone. They also work fine if I use the Edge Browser but I prefer using Firefox as I have for many years.

The embedded code is pretty simple, here it is for one of my counters... <a href="https://www.freecounterstat.com" title="visitor counter"></a> Can you help? Thanks, Bill T

Hello to your good team I am looking for a plugin for your browser that will do something for me I want to automatically refresh the site page and sound an alarm if the slightest change is made on the site. There is the same extension in the list of your browser extensions... but it doesn't give an alarm if the site changes. For example, I want the plugin to give me an alarm when I receive an email, or if the price of a product on the site changes, the plugin will give me an alarm. Help me please Thanks

I am travelling. I used a public wi-fi and norton VPN most recently. All my bookmarks are missing, altho they did appear on the toolbar briefly in the background. So where do I find them to restore them to the toolbar?
