Firefox Support Forum

The "Layout.css.page-size.enabled" configuration parameter = False ,worked effectively in previous versions, but after updating to Firefox 119.0, it no longer works whether I set it to True or False.

Orientation option is missing when I try to print documents from a website. The Firefox Print Preview window, which usually allows orientation choices for printing, is now not available.

Please advise. Thanks!

Hello,

I'm seeking help because sound is not working on Firefox. All other software are able to produce sound on every speaker and headphones I have. The speaker logo does not appear in tabs were videos or music is playing and firefox doesn't show up in EarTrumpet. It does show in the volume mixer but no bar appears to show it is displaying sound while media is playing.

I'm running : Firefox version 119.0 64 bits Windows 10 64 bits version 22h2, OS build 19045.3570

I've tried :

1. Restarting Firefox
2. Muting/Unmuting Firefox in the volume mixer, in firefox tabs too
3. Downgrading to version 118.02 32 bits
4. Uninstalling all my audio drivers followed by a restart (they got re installed but no change for Firefox)
5. Restarting Firefox with all addons disabled

I'm running out of solutions.

Kind regards

previously FireFox was able to login Spotify normally, and was able to post comments on Reddit, but suddenly it lost both abilities, and with the extreme lag on other sites, although still functional, i can't understand why these both sites can't be logged into, or can't post any comments in them. it has been this case for the past month. so what's going on? i'm NOT going back to Chromium based browsers ever again! i am in FireFox for a permanent replacement!

thanks in advance.

Firefox is my longstanding browser (on Windows 10). I wish to make use of the Firefox PDF viewer, but have been unable to gain access to it. If for the purposes of an attachment I click on "Open with", Firefox does not appear among the viewers offered. I'm not tech savvy, so a step by step (idiot's) guide as how I can gain access to and then make use of the Firefox as my default PDF viewer will be greatly appreciated, please.

Could anyone that uses Ublock please visit here to see if the video is being blocked?

Hello,

I have been working with OpenTable support for 2 months. We finally resolved it is not on their end.

Issue: When opening opentable.com the website loads and then a blank page is presented at the end. You can see a flash of the base site and any links that were attempted.

Items attempted to resolve:

• clear cache and history
• updated firefox site
• downloaded, uninstalled and reinstalled firefox
• incognito mode
• removed all all ons/plug ins
• tried links to pages outside of opentable.com

I have their responses and what they have attempted (in emails should you want). I also have snapshots of what I see. The odd thing is completely removing firefox and installing should have fixed it but it didn't.

One thing that does work is links to opentable from restaurants (email or from their websites). Initiating from the base browser does not work.

I am on Windows 10 and all updates have been installed.

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

Firefox won't play YouTube videos. I've tried everything. There seem to be plenty of problems on the forum BUT NO SOLUTIONS!

I'm ready to switch browsers - permanently!

Later version refuses to connect to my modem, and goes into security web mode. This modem uses HTTP/HTTPS for access, i.e., connects directly it's IP address, then the user enters a username and password. At that point, the the modem switches to HTTPS for control.

With this recent update, there is NO WAY to access the modem for any work, or upgrade the HTTPS certificate on the modem. This is a BUG.

What should happen is that if the web site will accept a HTTP connection, Firefox should NOT refuse connection or test for security issues UNTIL the user or the device switches to HTTPS.

As an aside, I've used Firefox on this Zywall modem for years until recently.

Firefox is blocking/preventing me from visiting a website even though it is secure but Firefox does not recognize the certificate issuer. How do I get around this? Thank you.

Artifacts on Youtube videoes when hardware acceleration is enabled. These artifacts is not there playing video on Chrome with hardware acceleration. Disabling acceleration removes artifacts, but videos runs poorly. These artifacts also appears in regular browsing. Intel GPU on latest driver. Since it works in Chrome with the same GPU on the same driver, the problem is in Firefox. Artifacts not there when running Furmark gfx burn in. So problem is not in the hardware. Problem still persistent even on numerous updates of Firefox. Windows 11, Intel HD Graphics 620 GFX, latest driver, latest Firefox.

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

Our office uses a cloud-based database. Mozilla won't allow me to "check" boxes to do database searches for specific things. Google works fine, Edge works fine, but not Mozilla. Any ideas on how to fix this would be appreciated. Thanks!

Hello Mozilla Support,

Since 2 upgrades ago, anytime I try to watch a livestream, my browser slows right down and then crashes.

I don't care why its happening, I just want a definitive fix for the issue.

I'm so aggrieved at this happening constantly, if you cannot provide a firm resolution to this issue, i will simply move to another browser.

I've tried your about:config setting restart to false and other fixes but still keeps happening.

I await your reply.

With Regards,

Mark

I've had this problem for a while and it's kept me from actually using the program. At any given time when I try to run the application, it never lasts for more than a couple seconds before it suddenly stops with no warning. Whenever I get these crashes, the Crash Reporter never opens. Because of this issue I can't open it in troubleshooting mode. At this point I have tried fully resetting my PC twice, uninstalling McAfee, had multiple malware scans, and have uninstalled and reinstalled Firefox itself multiple times. I'm really not all that good at operating computers, I just kind of know how to navigate files. I don't know what else to do at this point.

Hello, Live videos in youtube are not starting. No issue with regular ones. Also FB reels don't have sound and I need to press two times on play to start the video.

I tried with Chrome and Edge and I don't have such issue.

I have no extensions or add-ons installed. Cache and data are cleared.

Could you please help me?

In my ongoing battles with Firefox which no longer offers a painless way to use the internet, in Reddit's moderation page, messages are flashed up for a frame and then disappear and I'm told there's nothing to display. However, in Chrome this page shows the messages and I can use the page correctly.

Anyone else having this trouble?
