Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

Respectfully, Don

I have random Tab crashes in Firefox when running UI tests with TestComplete. TestComplete proviedes a dmp file. After analyzing with WinDbgPreview it provides an error with the xul.dll:

For a few weeks now, Firefox has been often freezing a webpage for 5-10 seconds during browsing. It mostly happens when going back to the previous page, but also when clicking a link or doing a google search. For those 10 seconds, you can't do anything on the page; no clicking other links or selecting text.

I've already tried: - troubleshoot mode; it still happens when all extensions are turned off - turning on/off hardware acceleration - creating new places databes - updating to the newest version

What can i do to fix this?

When i go to google.com and enter search query the tab "hangs" for about 10 seconds before the next page starts to load Same issue on 2 separate machines (1 intel laptop, 1 amd pc) both on newly installed windows 11 pro

what i've tried: safe mode, disabling hardware acceleration, disabling antivirus (kaspersky, without any browser plugins or safe browsing) , but the issue persists

here's the video: https://youtu.be/qMY-38z_TC0

I have A LOT of problems with FF since the last couples of updates. It started around two months ago and after one of the updates (and FF has constant updates which is pretty annoying) the browser immediately starting getting really slow and buggy. The browser keeps crashing constantly, is slow, loading websites end in "network cannot be found" notices and you need to reload pages all the time to get them to load, videos play in the background by themselves on saved tabs without being activated or started.... The redesign of the menu some time back, btw, have gone to worse as it's now more difficult to find the active tab than before.

I've followed all instructions to try and resolve it and nothing works. I have no virus or downloads on the system so this is not the cause. Plugins activated or not activated makes no difference. Changing settings in FF to whatever suggested makes no difference, using about: to change settings makes no difference.

The browser has really turned almost unusable.

Our organization recently upgraded everyone from standard Firefox to Firefox ESR 115

Several users continually get the following error:

XUL Runner

"This profile was last used with a newer version of this application. Please create a new profile.

Users are getting the error even after a new profile has been created.

We have tried uninstalling Firefox both through the Control Panel and using IO Bit uninstaller but the issue persists.

All users are running Windows 10 22H2 64 Bit

Not sure when it started but nearly every attempt to play Youtube videos results in the video freezing after about 1/2 second while audio continues, then the video jumps forward randomly before freezing again. Have reloaded, restarted, cleared history, cookies, etc, and nothing helps. Mean time Chrome plays the videos flawlessly. This is a recent problem with FF and needs fixing badly as it will just not go away.

I am using Firefox Nightly 119.0a1 (2023-09-04) on macOS 12.6.8 on an Intel 15' MBP.

When clicking on a link from an external app (eg. WhatsApp, Teams, etc.) with Firefox not running in the background, Firefox will open up but will not open the link. I have to go back to the app and click the link again for it to work.

This has been an issue for me for a while now and it only happens with Firefox as other browsers will work as expected.

Copy & Paste not working in Whatsapp Web page. I've cleared cache, rebooted etc. Copy & Paste works perfectly in Edge browser to its certainly a Firefox problem.

My Firefox is having some problems relating to audio.

If I open a YouTube video, the image will play but there's no sound, on Twitter also, and so on. On YouTube Music the player won't even start, giving the error "An error occurred. Please try again later." I noticed that the stereo icon that shows up in the tab, which allow you to mute the tab, won't show up when I'm playing a video on YouTube, Twitter, Vimeo, and so on.

Only Firefox has no sound, it's not muted in the Volume Mixer, neither in the app volume settings in Windows. I've followed everything suggested here here and here.

I think the problems may have started after I reinstalled my graphic card driver, but I'm not sure since I don't use this computer very often. I have a Windows 10 and my graphic card is a Nvidia GT 630, and the driver version is 474.44.

Like in the title, anything that has boxes on them have a weird white box or just not the right colored and flicker when hovering over them. The corners of the boxes also become not rounded. Happens on other websites like youtube too, not just the settings. Started happening when I updated to version 116.0.1. I downgraded to version 113.0 and everything was fine. Both are on fresh install so I don't think it is related to any extensions that I downloaded. I am using a device with arm windows so the platform is ARM64/AArch64.

I think Firefox updated on my laptop in the last day or two.

I never had a problem with Google Calendar not populating with my calendar info, but today I find that Google Calendar opens, but doesn't fill will data. Calendar still works fine in other browsers, so it seems to be a Firefox issue. What is the solution?

Other Google apps that I use still work okay in Firefox.

Hello,

I am using Firefox developer edition I noticed it has updated itself to latest version  : 117.0b1(64-bit)

I always have Firefox updates so version before that was the 116.b08

After the update on startup I get the error message attached I close it and then Firefox runs normally but this happens on every time I run Firefox.

I now have 115.0.3 and this problem still exists. It was reported right after 115.0.1 was released. When watching FreeVee on a Windows 10 desktop it stops a short while after an ad plays. It looks like it loses the ability to stream the main movie while streaming the ad. After the ad it plays about 20 seconds of the movie, probably what was in the buffer before the ad started, and then it freezes. I get the circle wait icon, like what typically happens when the Wifi goes down. After a while a message appears saying the Internet is not working. See attached image. Then I get the message (see other attached file) saying Video Unavailable. We're experiencing a problem playing this video. For assistance, please go to www.amazon.com/videohelp. Close Player.

I am currently fresh on Fedora 38 and Firefox 115 with multimedia codecs installed such as ffmpeg. I have problems playing videos on Facebook or Twitch, like in myday stories, reels, and feed. But in YouTube, videos plays perfectly so I think there is a bug going on here? I already tested turning hardware acceleration on and off but no avail.

I have set Firefox as my default homepage and browser, however whenever I do a search or try to go to a website, Firefox starts to load it and then the screen flickers for a millisecond and then Bing takes over - Firefox no longer appears and the Bing logo is in the upper left hand corner. How do I stop Bing from taking over?

As I use Firefox throughout the day, webpages will just stop for a bit. Sometimes its only a few seconds, other times for a few minutes. It is most noticeable when playing videos but does happen at other times as well. During the halt, I can still access Firefox's settings and all menu items. It is just website interactions that stop.

For example, when a halt occurs on youtube, the video will eventually stop, depending on the buffer, and scrolling through the comments won't pull up any more and replies won't load. Then after a few moments, everything will start working again without issue, and all the uncompleted actions (such as opening new replies or trying to go to another page) will execute.

I used to think it was related to my computer's connection to our company's access server, but refreshing my connection through a CMD ipconfig /renewall worked so rarely that I assume it was just coincidental timing.

I also tried turning off hardware acceleration, but that had no positive effect. I'll make a separate post about that issue.

The thing that fixes it every time is odd: launching Chrome. I wanted to make sure it was just Firefox, so I tried launching Chrome, and then Firefox started working immediately. (Spotify still plays when Firefox halts too)

Is there anything I can adjust to keep this halting from happening? I can manage right now, but it is sort of annoying to launch Chrome every time.

When I'm trying to go to a specific website, it doesn't connect with an error code "SEC_ERROR_UNKNOWN_ISSUER". I was able to press a button labeled "Accept the Risk and Continue" before, but the button seems to have disappeared?
