Firefox is not permitting videos from YouTube that other browsers easily play. This needs to be fixed. YouTube offers their Premium subscribers videos which can be played at a higher bitrate, which means even 1080p can play at a higher quality. When setting quality on a video, in addition to the 1080p, you can choose "1080p Advanced bitrate" as an option. Firefox has trouble playing these files, whereas Safari and other browsers don't have a problem with YouTube. Please fix this.

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?

This is a problem I've had for a while and thought it would be eventually fixed, but no luck so far.

TL;DR - Almost every time I add or remove monitors my Firefox hangs.

More context: I use a PC laptop and constantly switch from using just the laptop screen to using just a set of two monitors, with the laptop closed. What I do is, I lock my machine, with Firefox open on the laptop screen, connect the monitors, close the laptop lid, and unlock the machine. That causes Firefox to hang and I'm forced to kill it and open it back again. It usually reopens all tabs without a problem but the issue is pretty annoying.

My current version is 125.0.2 and I'm sure the problem dates from several versions

Out of nowhere, my cursor speed in Firefox has slowed to a truly unusable crawl. I refreshed a page and it was suddenly inching along at worse than a snail's pace. I'm using a USB trackball mouse. This is only affecting Firefox; no other applications have this issue. Using Windows 10.

Here's what I've tried so far:

• Restart Firefox
• Started Firefox in Safe Mode
• Restart computer
• Create a new profile in Firefox
• Check my mouse's firmware
• Try a different mouse

There was another question about this years ago, but the accepted answer about accidentally enabling a Windows accessibility feature doesn't say which feature it is or how to disable it (if that's indeed the case). The link also seems to redirect to a generic accessibility page.

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

Greetings everyone,

I've had this problem for a while and I don't know what to do.

I had a problem where Firefox kept crashing before it had finished loading up all of my former tabs and windows and so I was given the option of opening Firefox in "Safe mode" which I did, but now Firefox only starts in "Safe mode"...

I'm running the most up to date version of Firefox.

Thank you for any help!

When I run firefox on WSL2, buttons dont work on any pop up windows. Foe example when installing a firefox extention - it will download and pop up a small window at the top right to add the extentionto firefox. The buttons dont work. Another example is when opening up the firefox menu bar (hamburger bar) - it will pup up a small window to allow to open up settings, go to add ons, open bookmarks or history. The buttons dont work. Last example is the pop up window for this Ash your question page for firefox support - When clicking "Which topic best described your question - it will pop up a small window to select what type of question Im gonna ask. The buttons dont work.

I dont know how to fix this. I restarted, deleted my firefox profile, started of safe mode, nothing worked. How do I solve this issue?

Even after numerous Uninstalls and a Reinstalls I keep getting this error notice when trying to open Firefox...

The application was unable to start correctly (0xc0000022)

Running Firefox 125.0.1 on MacOS 14.2.1, all audio input is very quiet for all applications, not just Firefox.

Experiments I ran:

• people can barely hear me in Google Meets
• microphone works great in Quicktime (making a recording) when Firefox is running but not receiving audio input
• microphone is very quiet in Quicktime when running a Google Meet in Firefox
• microphone is very quiet in Quicktime when running a discord voice channel in Firefox
• microphone works great in Quicktime when running Google Meet in Chrome

This started maybe ~3 months ago for me. I'd love to see a fix, since Firefox is my favorite browser in most other ways - otherwise I'll have to give up and switch to Chrome at long last :'(

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

When I open firefox in ubuntu linux. (WSLg) Fresh install. I can't go to settings in firefox. Steps: press the hamburger menu, press settings, nothing happens.

OS: Ubuntu 22.04.4 LTS on Windows 10 x86_64 Kernel: 5.15.146.1-microsoft-standard-WSL2 Shell: bash 5.1.16

What the title says. While I was doing school work my session crashed and I lost all of my work. Upon reopening Firefox I was told my browser had installed the latest update for Windows. I then checked my crash logs and saw my session had crashed and Firefox had installed the update. Why could have this been? I would like a solution to this to ensure this doesn't haven't happen again. Thanks.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

In firefox Ubuntu (WSLg) the dropdown menus don't work. I have already tried reinstalling both firefox, and the entire OS.

When I press Custom URLs... (see image) nothing happens. This issue is everywhere in the brouwser, on websites, even when I press help in the hamburger menu. (Or settings in that same hamburger menu.)

I reinstalled the Visual C++ and Firefox loaded when i ran the Firefox repair but totally locked up. Unable to get to settings or any website and will not run after closing it.

So with Google becoming an increasingly terrible company over the years I once again decided to try to move away from chromium based browsers and over to Firefox, but I'm still having the same problem as I did when I first tried. I have since found the source of the problem, or rather a more exact explanation of what is going on, but I still can not find a solution. Basically when I compare the audio of the same YouTube video while logged into the same account with the same settings the audio quality on chromium browsers seems better. After some testing I figured out that it has to do with Logitech's G Hub surround sound option. Using Logitech's surround sound on headsets that support it, the Pro X2 in my case, will change the audio quality by quite a lot, in my opinion it sounds better. The problem is that this change doesn't seem to have an effect when using Firefox.

Is this a known issue and if yes, is there a solution?

I had used and uninstalled Chrome, and others. All I have is FF and ME. Some times when I attempt to open a web page, FF fails and I have to use ME. But other times ME fails and I need to use FF. I recognize that all browsers other than FF are the same or similar basis. So, how can I stick with JUST FF. And not have to keep ME updated or active. Just let ME sit there unused. Why can't FF work with all web sites? Is the problem with them or with FF?

This has been happening for months now, on multiple devices (I have tried at least 3 different devices), and on multiple networks.

I have read the articles in here, but they just want me to check network configuration which is exactly the same for all browsers.

If I restart firefox it starts working again.

How can I prevent it from breaking randomly? This is the only browser having issues, I'm almost positive is some bug and not a configuration thing, given that it happens under multiple circumstances and devices, while Edge and Chrome simply keep working just fine.

There is no consistent repro I can give, afaik it is just random, at some point Firefox just decides to stop working and I have to restart it. This disrupts my work and browsing activities as I can lose progress on input forms and similar actions.
