Firefox Support Forum

Versions: Firefox: 127.0 (64-bit) Linux: Ubuntu 22.04.4 LTS

Description: After some time, and (under unknown conditions), the input delay will shoot way up. Like 20-30 seconds.

Strangely enough, this only applies to keyboard inputs. I can change my tab with my mouse, I can click on things, no issues there. But any keyboard interaction is hugely delayed.

This does not fix itself until I close my browser and restart it. Closing the browser is always broken here too, if I close the browser with the [X] exit button, I then need to kill the process because it just hangs. It blanks out the contents of each tab like it's preparing to close them, but it just doesn't ever complete the task without a manual kill.

CPU usage and memory usage are relatively low; significantly below my system's limits.

I've already tried this suggested fix, to no avail.

The frequency of this is only about once a week at most, usually once a month, so it's not a huge issue, but I'm just worried about this occurring during a critical meeting or something later. Having this impending restart needed is kind of worrying for critical usage times.

Hey folks, I've been noticing something peculiar with Firefox that's been bothering me lately. Whenever I try to watch videos on YouTube in resolutions above 1080p, they tend to randomly buffer. It's quite frustrating, especially when I know my internet connection is stable and other browsers don't seem to have this issue. Has anyone else experienced this problem with Firefox? And if so, do you have any tips or solutions to share? Thanks in advance for any insights!

I'm working on developing a website that uses WebGL in it, but sometimes some bad code will cause WebGL to crash. The issue here is that once that happens, I have to go into troubleshooting mode and back out before it starts working again. Is there any way to make it so that WebGL works after it crashes?

I would just like to know why it crashes immediately every time i try to run it, my network isn't blocking it and i still cant run it even after turning off anti virus protection

ever time i watch something i will go to pause it and noting will happen and if hover over a video and preview it won`t stop until i close the tab how do i turn this off?

Greetings,

I'm a user of Mozilla, it's my main browser. I use it for everything and especially for Youtube. But, recently, some changes have appeared and not for better. I don't know why or if it's only me. The thing is Youtube is not like the real site but something else and so i lose options or settings. I don't have anymore the mutiple screen size options. There's a button that says "watch this on Youtube" while i'm litteraly on Youtube.. And now i want to watch a video with a age restriction and it'tells me i have to be connected to Youtube while i'm connected.

Can someone answer me about this or make it noticed by Mozilla employees ?

Thanks

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

i use Firefox as my browser, but AT&T Yahoo is my internet provider so I use a Yahoo home page and Yahoo mail. Last week they did an update, now every time my laptop goes to sleep I have to re log into Myyahoo to get my mail and my home page. It also seems to log me out of some of my other forums and websites at the same time. I'm not sure how to fix this in settings so any help would be great.

I'm on Firefox 127.0 (42448) ios and all my private tabs were closed on update and now whenever I make a private tab it disappears after the app is closed or refreshes. It's kind of behaving like the setting where private tabs are closed automatically but when I looked in the privacy settings of firefox ios it's not there anymore. Does anyone else have this issue? I know theres an existing problem with tabs for firefox but I don't think this is exactly the same because my normal tabs are totally fine.

The behavior began with fifteen to twenty crash messages appearing. After which the browser would stop responding and be unable to reach out to the internet.

Network connectivity was confirmed as I was able to access my VPN and corporate teams.

I submitted as many crash reports as I could. Eventually the crash reporter ceased to function. The message is:

Firefox had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash.

Details: expected value at line 1 column 1

Only a full reboot of the machine restored functionality but only temporarily. It returns after being put into sleep mode.

Running firefox in safe mode does not restore functionality. The behavior persists.

I am fully up to date according to firefox.

I am running a Lenovo Thinkpad Windows 11.

I have 2 soundcards on my iMac, (OS Ventura 13.6.1) : one internal (iMac) and one for music production. (universal audio)

Until the latest update (127), I could select either one and I could hear the audio from Firefox. But... since the update, only the internal iMac audio card is working. Note that I don't have this problem with Safari nor Chrome and it used to work on Firefox until the last update.

Anyone has noticed that? 

Does anyone knows how to contact them and log this as a new bug?

Thanks all!  :)

For a few months now, I have been having issues with Firefox and my computer audio. If I am listening to something, like internet radio (doesn't matter which website), the audio will completely cut out. Sometimes it will start working on its own and other times I either have to force quite Firefox or completely restart my computer. When this happens, no other audio works on my computer. I have had a new motherboard, audio card, speakers all replaced under warranty. I've also re-installed Windows and it still keeps happening. Has anyone else experienced this? Can anyone recommend a solution?

Issue Summary: When using a maximized Firefox window with the Windows taskbar set to automatically hide, the taskbar sometimes fails to appear when moving the mouse cursor to the bottom of the screen.

Steps to Reproduce:

• Set the Windows taskbar to automatically hide.
• Maximize the Firefox window.
• Use Firefox normally and intermittently move the mouse cursor to the bottom of the screen.

Expected Behavior: The Windows taskbar should appear when the mouse cursor is moved to the bottom of the screen.

Actual Behavior: The taskbar does not appear consistently when the mouse cursor is moved to the bottom of the screen. This issue is specific to Firefox and occurs frequently, though not every time. The taskbar functions normally with other applications.

System Information:

• Windows Version: Windows 10 Pro 22H2 x64
• Firefox Version: Firefox 127.0 (but happens at least since 126.0)

Additional Notes:

• The issue has been occurring for several weeks.
• No specific pattern has been identified regarding when the taskbar fails to appear.
• This issue significantly impacts the user experience as it disrupts workflow and navigation.

Steps Taken to Resolve:

• Checked for and installed the latest Firefox updates.
• Restarted Firefox and the computer.
• Verified that the taskbar behaves normally with other applications.

Request: Please investigate and address this issue in a future update. Any guidance or interim solutions would be greatly appreciated.

Thank you for your attention to this matter.

Every other browser works fine. This one stopped dead on Win10 and Android9. It wont stream even in safe and my Android has no add ons

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

I know it seems like a minor thing, but I run my browser in the left hand of my screen with other apps to the right, so that gaps pushes all my pinned tabs and browsing tabs over to the right losing valuable space. It's not there on my Windows machines where I run a similar layout.

Anything that I can do about it in about:config?

For many years I have used the ability to set shortcuts to website on the Firefox home tab, using the method given at: https://support.mozilla.org/en-US/kb/customize-items-on-firefox-new-tab-page#w_pin-unpin-or-remove-a-shortcut.

However, today, when I try to edit a shortcut link, I do not get the 3 dots menu by right clicking on a shortcut tile.

Is this a recent change, a bug, an issue with my installation (which has been stable for many years)?

How can I get back the functionality back?

I am using Firefox 127.0 (64 bit) on Windows (Windows 11, all up to date).
