Auto play blocking is no longer working.

media.autoplay.block-event.enabled true media.autoplay.blocking_policy 3 [tried 2] media.autoplay.default 5 [tried values]

Anyone have good values that block auto playing videos?

Had to replace FF with Chrome in order to play DRM content on my W11 laptop. I get message saying you are downloading remedy, but nothing ever changes. Would prefer to continue 15+ year relationship with FF, but seems like youre abandoning capabilities for DRM video content?

I use Mozilla as my browser on Windows 7. When I click on Mozilla I get an Error page which reads, " Server Error in "/" Application. Runtime Error. Not sure how to fix this. Can you help. Thank-you

PR_END_OF_FILE_ERROR how do I get rid of this error that keeps popping up when I attempt to launch Amazon.com I have never had this happen before..... it just started about a week ago.

UbuntuStudio 22.04 uses the Firefox Snap package by default. The latest automatic update does not display pages correctly in normal mode, but does work correctly on Safe Mode. Snap.io lists only the latest version of Firefox so I was unable to ask snap to revert to the previous release (prior to 5 Mar 24) and by the time I had tried to investigate the previous version was no longer cached. I did not see a way to force a fresh download of firefox from the latest channel on snap.io.

I tried the snap beta channel for v124, but that exhibited the same problems.

I tried adding a symbolic link to colors.css after seeing firefox complaining that it could not be found when started from the command line. That removed the error/warning message but did not clear the problem with normal mode.

I use the en-GB locale extension only. The technical details about my PC are as follows:

• Operating System: Ubuntu Studio 22.04
• KDE Plasma Version: 5.24.7
• KDE Frameworks Version: 5.92.0
• Qt Version: 5.15.3
• Kernel Version: 6.5.0-25-lowlatency (64-bit)
• Graphics Platform: X11
• Processors: 12 × AMD Ryzen 5 7600 6-Core Processor
• Memory: 30.5 GiB of RAM
• Graphics Processor: RAPHAEL_MENDOCINO

I have now downloaded v123 and installed it in my local home directory, and that version is working well. I have removed the firefox channel via snap. It is likely to be a fault in the construction of the snap for v123 that was not present for v122 prior to 5 Mar 24.

...and i love this product so i would love so much to solve this. thank you.

Hi,

Occasionally when downloading files on Firefox, they'll freeze completely (often at the very end.) There is no way to pause or cancel the downloads, except to restart Firefox.

When I attempt to restart Firefox, it closes the browser window. However, when I try to reopen it, I get an error message stating that Firefox is running but not responding. The 'Close Firefox' option does nothing, except make the box pop back up a moment later.

I can't kill the Firefox process in Task Manager or Process Explorer, because it says access is denied. I can't kill it using taskkill in command prompt because it says there is no running instance of the task.

The ONLY thing that seems to help is completely restarting the computer, which is getting frustrating to do several times a day.

I can confirm Firefox is up-to-date. Any tips are appreciated, thank you!

I have two end users that are having a different issues but they are of similar nature. First user can not upload anything to Microsoft Share point. She gets a message that says she does not have proper permissions to upload. She does not have the same issue on Chrome or Edge. The second user is trying to download and or save a file from a couple of different websites but regardless on where she tries to save it on her computer it says she does not have proper permissions to save to "x" file location. She also does not have this issue when she is on Chrome or Edge.

For both users I have tried clearing cache and cookies, Rebooting their computers, uninstalling and reinstalling Firefox, deleting registry keys/user data from the computer itself. I have had no luck with resolving this issue and I can not find anything online that remotely resembles this issue.

Thank you and please advise

Firefox keep crashing when I use certain websites (realtor.com is one that comes to mind). I use a Macbook pro. I've updated my operating system, updated Firefox, and tried to use Firefox in troubleshooting mode. Everything is up to date, and the crashes still happen in troubleshooting mode. Here's the crash code: bp-80317ed2-74bc-4df1-a867-a6a130240322. Any ideas how to fix this? Thanks a lot.

Firefox has been white-screen blocking my access to some common websites including CNN, Amazon and possibly others. No error messages, just a blank white screen. This is a sudden change and has never been a problem in the past. Chrome and Firefox on my other computers are not affected. I have cleared caches and deleted all tabs with no change in symptom. I've also checked CPU and memory resources and both appear normal. No sites are being blocked by settings either, though I would expect Firefox to give me a "This site is blocked" message of some kind if that were the case. How do I fix this?

This happens now a lot, sometimes I can uninstall Firefox reinstall and it works. That worked this time but only for a few days. I am back once again to where I get this error on every place I visit. I have cleared my cache etc.. uninstalled reinstalled did a restore. It is only Firefox all other browsers work fine. No idea what to do anymore and am sad because I prefer Firefox. I only have standard windows 11 home security stuff installed so nothing special or fancy firewalls. Tried turning on default fire wall. Tried all the instructions on the more info page the error screen leads to.

This error occurs on most all websites or places I need to log into

Secure Connection Failed

An error occurred during a connection to mail.google.com. PR_END_OF_FILE_ERROR

Anyone know why this is happening and a solution?

i use firefox on ubuntu and a dropdown terminal app called tilda. i configured the F1 key in the system to bring down the tilda terminal. it works in every other application, just when firefox is in front, the F1 key does nothing. it wasn't the case before, now it is.

I am a startup founder. I'm making a webgl rendering engine. I'm doing a stress test with 4 large paragraphs amounting to tens of millions of triangles on a macbook air. Firefox is on the latest version.

When I run the app in chrome/safari/opera, the performance is normal. ~45fps. But in Firefox, it's very slow. My FPS counter (in a requestAnimationFrame loop) says ~45fps on all browsers. But in Firefox, even though the counter says that, the real frame rate is ~3-5fps.

When I try to profile, the problem magically goes away and we're back to ~45fps. I played around with profiler settings, and the key determinant is whether or not I'm taking screenshots. No screenshots = slow. Screenshots = fast.

In the flame graph, in slow mode (no screenshots), it seems like I get stuck in the canvasRenderer and the Renderer mostly waits for it. But in fast mode (with screenshots), the canvasRenderer keeps up and the Renderer spents most it's time in: iokit_user_client_trap

I'm not sure what to do. This is only a problem on Firefox. There's some sort of gpu/threads/something that switches when I profile with screenshots that makes it way faster. This performance hit basically ruins my app for Firefox only. Any idea what I should do?

I have a macbook pro running Sonoma 14.2.1. A few days ago I noticed the computer didn't update to the current version of Firefox when I attempted to do so after being prompted that an update was available. I went to "About Firefox" and saw the error message "Failed to check for updates". Please help. Thanks.

Hello,

I am experiencing a persistent issue with web browsers on my Lenovo Legion T5 26IAB running Windows 11 Home. Regardless of whether I use Mozilla Firefox, the browser frequently crashes. This happens at least once a day, and it seems to be unrelated to the number of tabs open or the specific content being viewed. I did the help -> diagnose mode without plugin and it crashed too, im not sure what this is realted to.

The crashes often present with an error message suggesting a failure in the new tabs or trying to load a old one, despite the fact that my system's RAM usage is typically around 60-70%. I have already updated the BIOS, Lenovo drivers, and NVIDIA graphics drivers, but the issue persists.

I'm seeking advice on what might be causing these browser crashes. Is it possible that there's a compatibility issue with Windows 11 Home? Could it be related to the graphics card or its drivers, even though they are up-to-date? I have not changed the power cable from my old PC; could this be a factor?

Any insights, suggestions, or similar experiences would be greatly appreciated. I'm trying to determine if this is a hardware issue, a driver conflict, or something else entirely.

Thank you in advance for your help.

Windows 10 Pro v 22H2 Firefox 121.0.1 (64-bit)

I have tried preventing Firefox from autostarting with Windows start up by examining these potential program starting locations:

Firefox-Settings-General: "Open Firefox automatically when your computer starts up": Option not available about:config - toolkit.winRegisterApplicationRestart - set to "false" No listing for Mozilla or Firefox in Windows 10 "Startup Apps" settings page No listing for Mozilla or Firefox in Windows 10 msconfig.exe/System Configuration-Startup No listing for Firefox in Windows 10 Task Scheduler No Firefox program in Windows 10 - %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder All Firefox extensions (2) are disabled

Where else should I be looking? Thank you

Hello,

We are using a Sharepoint site with an embedded page, and when clicking this page it brings us to this support article. Is there any way we can edit the settings in Firefox to allow for this page to open? https://support.mozilla.org/en-US/kb/xframe-neterror-page?as=u&utm_source=inproduct

Firefox uses 2.1gb of RAM with 6 tabs opened which is far more than it ussualy does and it sometimes just jumps to 2.5gb. ((Fore the Image) My task manager is in german so Arbeitsspeicher=RAM)
