I've been out of town. After returning home Firefox updated to 127.0.2 but now it will not close its process when I close its window. When I try to launch Firefox again I get the error message below and attached:

"Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window. <Close Firefox> <Cancel>"

When I select "Close Firefox" the new Firefox window will then launch. However, if I open any web page the same error occurs after closing the window.

If I launch Firefox and then close it without opening a web page I do not get the error the next time I launch. Somehow going to any web page in Firefox prevents that instance of Firefox from closing.

I'm running Windows 10 22H2 Build 19045.4529 and it's shown as up-to-date.

I can't download anything by that green download button (Youtube). I just receive error messages, see attachment. I have read their FAQ and I have latest versions of Firefox and savefrom.net helper.

Almost daily I get a message to download or dismiss update. When I dismiss the message, it continues to pop up. When I hit download, nothing happens. This is locking up my computer at times & slowing everything down. I actually don't see the need for daily updates. What is causing this and how can I stop it?

First, I fully realize that my OS is prehistoric - beyond ancient. I simply cannot afford to upgrade right now - I'm working on it, though. So, since the last update on ESR, everything seems to be working well, browser-wise, except for a sudden change when using FB. They're problematic, so I thought it was something there, but there are no problems with any of my other devices ( 2 phones & an ipad). For most situations on FB, without going into the whys, I need to use my/a laptop, instead of anything else. It has begun freezing and lagging -sometimes, for 10 minutes - after I start typing! And, the emoji panel takes that long to appear, then longer after hitting one! It's basically unusable. I already contacted them, and as previously mentioned, the laptop is the only problem after the last update, the other devices work well, in terms of speed. I'm wondering if there's anything I can do here to remedy this. I have 9 billion bookmarks and my settings are set in stone, so I can't risk losing any of that by reinstalling, or anything like that. I've been with Firefox since it became available, many years ago, so I'm not willing to sacrifice anything I've collected. All was fine, until this last update. And, I'm working on getting another laptop. Thank you for your time.

My Local Inbox suddenly started to arrange itself by group according to correspondent. I can't get the emails back into chronological order. I can't work with a mail program that doesn't give me my messages in chronological order, with most recent at the bottom. If I did something to cause this change, please tell me how to undo it. I have about eight email addresses, and they all feed mail into the Local Inbox.

At some point about 5 days ago, Firefox began to load YouTube videos unacceptably slowly. To begin a video it may take around 30 seconds or more to load (with a black screen and circular loading bar/graphic), and randomly throughout the video it will need to load again which has taken up to 5 minutes at times.

Steps I have taken: - ran Firefox in troubleshooting mode (issue persisted with no extensions) - minimized memory usage - disabled hardware acceleration - refreshed Firefox twice - reinstalled Firefox

Testing/comparing YouTube in Chrome and Edge, videos load near instantaneously (even while running an extension such as uBlock Origin), and I can click anywhere in the duration of the video and it loads in less than a second. Strangely, sometimes the issue doesn't persist for the next 2-3 videos that I try to play, but then goes right back to an extremely long load time for the next video. I've never had such an issue with Firefox before and cannot find a solution. Extensions don't appear to be an issue and other browsers run YouTube perfecty fine.

On the top of the left side of the incoming email page, next to my email address, I would like the following alternatives to appear: answer, answer all, forward . . . I have had them before, have never had a problem with them, but I must have pressed the wrong key as now I get the following instead: an icon with a pin-up button, a phrase about filtering, and then five icons with an envelope, a star, a notebook . . . What do I need to do to recover the original layout?

This new version of Thunderbird (115.12.2) is not the best. The Composition toolbar doesn't exist when typing a new message and I no longer have a menu bar when typing a new message.

Another issue is on replying why do these sideways "V's" show at the beginning of each line of the senders email when replying. Sometimes it will be just a black line all the way down. When I saw those I felt like I had woken up in 1995.

I am using Windows 11 Pro.

Thank you

For about a couple of weeks, there has been a lot of delay between what I type and when it actually appears. It's maddening! I have not changed any of my Firefox settings. I did a 'refresh' about an hour ago. I am not seeing any network activity that I cannot recognize. I d/l'd 'Malwarebytes' and ran it..."no threats". MS Defender has always been on & protecting me. I have never had this situation occur before and am hoping for some help (5 to 10 seconds to wait for what you've keyed in is not fun).

Even though I actually have only 1, 2, or 3 Firefox windows actually open, subsequent browsing is is stacking up instances. Following is a copy of Windows' "processes screen" illustrating an actual instance. At this point, I run out of memory and Firefox crashes.

Hello --

Not sure when this happened.

Got 2 email accounts, account X and account Y. All was working fine until today, 6/27/24. Both have different outgoing SMTP servers.

Now I am trying to send, it is asking for passwords, which I have and is 100% correct. In fact, if I put in wrong password it tells me, so I know it is communicating. When I put in the correct password, I get a timeout on BOTH SMTP servers.

I disabled Norton Firewall.

Works fine from another PC app (poppeeper) and from my android (k9 mail). Both accounts are IMAP.

Neither SSL/TLS or STARTTLS makes a difference. Nor did a re-boot.

TB 115.12.2 (64 Bit) on Windows 10

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mailroom4.hostrocket.com timed out. Try again.

Description: hostrocket Server Name: mailroom4.hostrocket.com Port: 465 User Name: ernie@e(redacted).com Authentication method: Normal password Connection Security: SSL/TLS

Anything change?

A few days ago I tried to download something from a modding website for a game, and the download simply failed instantly. I thought it might have been an issue with that website, but after pressing on with my plans with Edge and later trying to download Microsoft Visual Studio through Firefox, it failed again.

A week or two prior downloads were working fine, and I hadn't changed any Firefox settings between now and then. There's clearly something blocking downloads, but I don't know what. I'm not adept enough at fiddling with individual settings all day to know what they do or figure it out easily. All I know is that pretty much all of the conventional solutions from the most recent posts about this (2+ years ago) are not working. I've tried messing around in about:config and about:profiles, tried disabling and unchecking Firefox security settings, and changing the directory for downloaded files. I've even tried disabling Windows Firewall and Nord VPN.

I keep getting "can't connect" message and I have to enter my password for outgoing mail. Incoming comes through no problem. How can I get Thunderbird to remember my provider password for outgoing? They obviously already have it for incoming.

I've been having this reoccurring firefox bug every couple of months where randomly all audio from the application stops working is no longer available in the volume mixer of windows 11 (see example screenshot with twitch tab in background playing)

In the past, I was able to fix this issue by simply restarting the audisrv service and everything would work normally but now nothing I do seems to work. I've tried:

- Resetting - Uninstall/reinstall - Disabled all extensions - New profile

I do not have this issue on firefox dev or firefox nightly. If anyone has any ideas on how I could resolve or better diagnose this issue it would be much appreciated! TIA

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

when clicking an email link this is shown

"Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

How do I make Thunderbird instead open a new email?

This is on Fedora

This problem began a couple days ago. I have no problem accessing other sites on Firefox (and none for this site over years of use.) Can access site on Safari without problem.
