I'm getting the error message "No video with supported format and MIME type found" with mp3 files at https://www.gatherthepeople.org/test/styled-7/page-3/ when using Firefox 123.0 on my M1 (ARM) iMac running OS 14.3.1; when using Firefox 123.0 on my M1 (ARM) MacBook Air running OS 14.3.1; when using Firefox 123.0 on Win 11;and when using Firefox 115.8 on my Intel MacBook Pro running OS 10.14.6.

Thanks

Firefox Browser 123.0 (64bit) Windows 11 Pro

Lately I have been experiencing issues/difficulties to access certain websites either an security issue (eg Site needs to verify the security of my internet connection. This verification process times out and of course results in not getting access. Or the following message gets displayed when accessing this site:

"The page isn’t redirecting properly

An error occurred during a connection to mynikonlife.com.au.

   This problem can sometimes be caused by disabling or refusing to accept cookies"

In both the above cases I experience no difficulties, using Microsoft Edge. Is there an solution to this or do I start using MS Edge (which I do not want to)?

Running Windows 10 and Firefox 102.9.0esr 64-bit. I seem to have affected the print facility so that the contents of a frame within a webpage do not print. The frame contents do show on the preview screen but then disappear when the Print button is pressed and they are not printed. The rest of the webpage is printed OK. Typically this happens to the 'Sellers Description' on an Ebay item. I have upgraded to Firefox 115.7.0esr but this has not fixed the problem. The print works fine on another machine running Windows 10 and Firefox 91.6.0esr 64-bit. Is there a way to get the full print back? Regards, LRB

There are sites, including yahoo that all my comments are coming back as "comment failed to publish" or other sites where comment section just not there. Seemed like this started happening after a recent Firefox update. I have contacted web sites, my protection service and they have, after research come back with problem is Firefox. If there' something I've done or not done to have this happen, let me know. It DOES NOT happen when I use, as example Edge or anyone else. Thanks......Mike

Firefox is frequently deleting entries made on websites. I am entering information in boxes (like this one) on websites when suddenly FF bails out, the data vanishes off the screen and leaves me back where I started. It happened several times attempting to post this question. This seems to have something to do with hitting a key or the space bar--but what and why eludes me. I have tried changing settings on trackpad and mouse without any impact. Although this is a recent issue with a new computer, the issue does not occur using the same computer on Chrome. Any ideas?

I run the latest Firefox (v122.0.1) on Windows 11.

Since last week, FF takes 14 minutes to start the first time after a boot. :-( Usually FF starts in ~3 seconds.

I reboot the laptop. I wait a minute. I start FF. Nothing happens for 14 minutes. Finally the browser window suddenly appear and everything is working normally. I exit FF (no remaining firefox.exe processes are running). I start FF again. Now it starts immediately as usual. :-) But: I reboot and start FF. Again, it takes 14 minutes to start. This is reproduceable every time.

I haven't tried to *solve* this by refreshing FF or simillar. Right now I'm more interested in debugging this and finding out what is wrong.

I found https://profiler.firefox.com/docs/#/./guide-startup-shutdown which states how to automatically start the profiler at startup.

12:40 I boot the computer, login and wait a minute. 12:43 I start CMD.EXE and run:

 cd c:\Program Files\Mozilla Firefox
 set MOZ_PROFILER_STARTUP=1
 set MOZ_PROFILER_STARTUP_ENTRIES=20000000
 set MOZ_PROFILER_STARTUP_INTERVAL=100

12:44 I run:

 firefox.exe

No GUI appear. (it won't appear until 14 minutes later) I open the Task Manager and see one (1) firefox.exe process, taking 0% cpu. (pid 17668) 12:48 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:50 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:52 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:54 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:56 One more process running for a few seconds. Commandline is just "c:\Program Files\Mozilla Firefox\firefox.exe", no more options. 0% CPU. 12:58 The browser GUI finally appear. Everything is now normal. It is showing one (1) tab with my start-page (google) just as it should. (my Task Manager now show 12 FF processes running, with various options) 12:59 I click the icon to stop the profiling.

I open the profile. [Profile Info] says:

 Recording started: Sat 17 Feb 2024 12:58
 Recording length: 1m12s 

So my profiling data don't show what happens between 12:44 to 12:58 :-(

Just for the sake of it, I'm attaching a pic of the first 10 seconds of the profile (at 12:58).

PS: Between 12:44 and 12:58 no FF window exists at all. Alt+Tab show no FF and in Task Manager I can't do any "Window" management, it is greyed out. I.e. no FF window exists for this process.

Question 1) What should I do to debug what happens between 12:44 and 12:58?

Question 2) How can it be that it takes 14 minutes to start FF from scratch (boot) while it starts quickly (~3 seconds) if it has been started once? I mean, all firefox.exe processes are gone when I exit FF, so starting FF again should be like starting from scratch, but apparently something is different.

Question 3) Is it normal that a FF, with only one tab (https://google.com/), run 12 processes in Task Manager?

How can I turn this message off? Some sites I visit give me that message, it shows up when I'm typing a reply to something which pushes the page lower and fouls up my ability to keep typing, then if goes away, comes back, goes away ... I just want to kill the message entirely. I'm not worried about speed, there's nothing to fix, I just want the message gone.

I have the same problem https://support.mozilla.org/en-US/questions/1421734 it's not a pdf. If I want to print a shipping label from eBay using Firefox nothing happens if I try to make it bigger. I can make it smaller but it is too small to begin with. If I use Brave or Edge (using the same printer) it works I can adjust it and make it bigger up to 200 %. I have already reset the printer options in Firefox and tried when disabling all add-ons.
