For Windows version 10.0.19045 Build 19045 If using Firefox Version 113.0.1 (64-bit) in Windows 10 and in the following state:

 Firefox is open and window is maximized.
 Firefox Full Screen is toggled OFF.
 Windows taskbar setting "Automatically hide the taskbar in desktop mode" is toggled ON.

Then the Windows taskbar will not display when the cursor is place at the bottom of the monitor screen. If the Windows taskbar setting "Automatically hide the taskbar in desktop mode" is toggled OFF. Then the Windows taskbar will also not display. Changing the ON/OFF state of any other Windows taskbar display setting in any combination does not fix the failure.

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 been using firefox for more than 4 years now. But from about a year, i m facing the issue with the Sudden High CPU usage in Windows task manager.

The task manager has 2 different firefox processes. One being actual instance i am running. and the 2nd being the automatically opened in background.

i have figured out whenever i have active internet connection and my system is on charging the 2nd task automatically starts in background and uses upto 80% of cpu usage. Ending the 2nd task form task manager doesn't affect anything. only the cpu usage drops. Also Closing my firefox instance does nothing to that 2nd task.

I have tried lot of solutions i found on community. Nothing seems to help. problem still persist. I even posted comments on ongoing threads. but no reply from anywhere.

this is the last time i m trying. if i get a solution its good. otherwise i am going to shift to edge. I have no other choice.

Screenshots from multiple dates are attached.

Since the task limit option seems to have been obliterated? I believe the many more "programs" and the events they create for windows to handle is causing all sorts of virtual memory problems. Changing win10 advanced system settings from performance for programs to background services seems to have restored Firefox performance in my case, see: 10 advanced system settings win10 advanced system settings performance programs vs background services Is there an about:config option that would allow one to achieve the same "programs" limiting option as before? This laptop has 16 gig of memory and I used to successfully have even better Firefox performance with windows virtual memory turned off, but eventually I would get crashes. I can understand why Firefox was modified in a way to better localize the source of crashes, but in my case it has degraded performance. Thanks Mozilla for a great product I have valued for years!!!!

I just spent 15 minutes browsing and downloading a lot of images. When I was done I looked at my downloads folder and saw only half of them there. I checked the download history in firefox, and couldn't see some files. They were not queued or in progress. They weren't in the download list at all.

I reproduced this. I downloaded an image again. Right click, save as, click save. Then that image doesn't appear in the download history.

I tried some variations. Hitting enter instead of clicking save. Opening the image in a new tab and using ctrl-s.

Still, no image in the download history or on disk.

I quit firefox and re-openned. Still the file didn't appear on disk or in the download history.

Then I kept trying, and I got a second issue, which I think is related.

Often when I save an image, instead of one window popping up asking me where to save it, I get a second window popping up ontop of that, then a third, then a fourth. All ontop of each other. All asking the same thing. They take the focus, so it's not possible to interact with the main firefox window to continue browsing.

Sometimes if I hit enter literally 50 times then it will save the same image repeatedly, and eventually I can go back to browsing.

Sometimes there's more than 50 popup windows (my hunch is more than 100). My only solution then is to quit firefox forcefully. Which is annoying if I have state in other tabs that I don't want to lose.

This has happened many times over many weeks. It only happens on some file saves. I can't figure out why it happens on some, not others. (Right click > save, and also ctrl-s, they both do the same thing.)

This form won't let me attach a screen recording. Only screenshots. That's annoying because you can't really see the behavior from the screenshot. But I'll try. See the dark black border outside the download dialogue? That's normally a very faint transparent shadow. But because there's so many duplicate windows all exactly ontop of each other, those multiple transparent shadows have become opaque.

What you can't see from a static screenshot is that I could see each window appear ontop of the other. If I try to select the filename text and edit it, very quickly another window appears ontop with the default filename again. I can see the Firefox icon in the Gnome bar on the left shaking every time a new window pops up.

(Hmm, it looks like I can't *upload* screenshots either. I click browse, select a file, and then it doesn't get uploaded.)

I'm on Ubuntu 22.10 with Wayland.

I don't know if this issue is a bug in Firefox, or in Gnome. I've only seen this behavior with Firefox in Gnome. Not Firefox on another DE/OS. And not any other application in Gnome. This behavior has been intermittent since I bought this laptop and installed Ubuntu about a month ago.

The last update 113.0.1 was when I really noticed it being slow. None of the current suggestions have any effect. I have restarted several times, cleared cookies and history, flushed dns and have gone through all settings. Privacy is set at "standard" and not using a VPN and have turned off add blockers with no effect either. I have to check, but I don't think I have any add-ons except for color on home page.

If I do a speed test, ping is kinda slow, download is half what it should be at times, and every test shows ZERO upload all using several sites to test from . The only thing not done is shutting down av which I won't do. Anyone else seeing this issue? Any other suggestions than the go-to stuff here? Windows 10

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

I have removed cookies and site data of localhost in Privacy-and-security> Manage-data>

Whenever I try to download a file from google drive, I get: "The page isn’t redirecting properly An error occurred during a connection to drive.google.com. This problem can sometimes be caused by disabling or refusing to accept cookies."

Downloading google docs files from drive works fine, they convert to word and save to my downloads like normal. But downloading image files or pdfs yields this error. Right-clicking and downloading them from the folder view just does nothing. There is no difference between shared files and my own drive files. This error only happens in firefox, I can download files on microsoft edge just fine.

This has been happening for a few weeks now. Things I've tried:

-clearing cookies and cache -restarting firefox, restarting computer -checking for updates and updating firefox -disabling all my add-ons -clearing startup cache -adding drive.google.com and google.com to the exceptions for enhanced tracking protection -switching from standard to custom and unchecking cookies from the list of trackers and scripts to block, then clearing all cookies and cache -attempting to download in firefox troubleshoot mode -attempting to download in incognito mode -refreshing firefox -re-installing firefox by following the steps here: https://support.mozilla.org/en-US/questions/1233618 -turned off real-time protection on computer antivirus (default for windows 10) -turned off microsoft defender firewall

I don't even know what else I can try. I assume it's a firefox error because this only happens using firefox on my laptop - I use firefox mobile and can download the same files on my phone. Does anyone have any advice?

I use Firefox on Ubuntu 22.04, and my system has 16GB RAM. I have been facing this problem of frequent crashes for the past few months. By crash, I mean not Firefox alone, but the entire system. I use several apps and run several processes that require great compute resources, often simultaneously. I have narrowed the cause of frequent system crashes to Firefox alone; the system rarely crashes when I use other resource-heavy apps. Due to this, I have to restart my system several times a day.

Before this problem arose, I would use multiple tabs (including YouTube, often 10+, close to 20) and multiple windows (2+). Such usage very rarely caused crashes, which is why it is surprising that Firefox now causes the entire system to simply hang sometimes with as low as 3-4 tabs.

I have disabled Hardware Acceleration, refreshed Firefox, even tried disabling WebGL. I also tested it after removing all add-ons, but it still didn't help (I use only 2 add-ons: a simple wide-spectrum ad-blocker and an EPUB reader). Even in troubleshoot mode, Firefox will cause my system to heat up, although it takes some more effort to crash in this case. I use one of the standard themes, so it could not have been the problem.

Many people report Firefox crashes, but in my case, Firefox causes my entire system to crash. How do I fix this issue? Thank you in advance.

Hi Folk,

Firefox runs perfectly smooth in 3840x2160, so this is not a perf issue. However when switching from onboard laptop screen (2k) to my external WQHD screen, Firefox does not refresh, not reacting to input or mouse until I switch back and forth from another window. So it only refresh/repaint when main window looses and gets focus.

I have to restart firefox to make it works again.

Configuration: Linux debian stable (11) (same on PopOS) CPU: intel 8550 / GPU: Intel HD 620 RAM: 16Gb External monitor connected through usb-c 3.1

It does the same with Thunderbird. My Qt apps and terminals (alacritty) are not impacted.

When I scroll down to look at recent posts on Facebook groups I follow all but the top one has suddenly lost its date/time – I just get a blank where the details would usually be and have to hover over to reveal the details. The silly thing is that this only happens when I sign in and it doesn’t happen when I use chrome – although I prefer using Firefox, not least because the bookmarks sidebar is better. I have tried getting rid of all extensions and running in troubleshoot mode but without success. Any help/advice would be appreciated (as long as it is not about football!)

Hello,

Since some days I can't upload or download anything using Firefox. Right-click on an image and click "download" - nothing happens. Right-click on a web page and click "Save Page as" - nothing happens. Try to upload a file to DropBox or Google Drive - no popup appears, no error message, no response whatsoever. Opening the downloads list in the browser and trying to open the folders where I had previously downloaded things (when downloading was still working) also has no effect - the folder does not open on the desktop.

So apparently the problem is some kind of broken interaction between Firefox and Ubuntu (Nautilus?)

Downloading and uploading works normally with wget and Chromium.

Steps already tried: - Resetting all browser data - Refreshing the browser - Activating troubleshooting mode

Firefox: 113.0.1 Snap canonical-002 1.0 Ubuntu 22.04.2 LTS

Hi Firefox won't stick to the taskbar after a reboot of the pc. And it is also showing that it likes that it is install even after a totally clean re-installation of it.

Hello all,

I am having problems with video playback on some websites (see screenshot attached). The problem is that the video options start to "multiply" - for example, when I start the video there is (as is normal) one 'Speed' and one 'Quality' button, but then every second these buttons start to multiply. This happens only on some websites - for example, it does not happen with normal videos on YouTube, although it happens on YouTube Shorts sometimes.

This is my first question on the Mozilla Support page, I thank you in advance for your help and I hope I follow the community guidelines. Please feel free to leave any suggestions or feedback concerning how I should proceed for asking for help in the future.

for some time I've noticed this loss of frames when watching YT videos and YT notification drop down is activated. MX 19 Linux desktop MX 19 Linux laptop

I haven't seen any posts on this issue via search

Is this a driver, plugin, .. issue ?

When I try to upload a file through Google chat, Firefox crashes on the image preview of a file that is selected. When I restart Firefox, it uploads fine on the first attempt. If I continue to upload images, Firefox crashes again. This has been happening over the past few weeks. I'm using a mac desktop and Firefox version 113.0.1 - is there a way to disable the image preview when uploading files? Thanks in advance.

Firefox is using a massive amount of ram for an unspecified task, simply defined as "GPU" is the baked-in task manager. The attached image is after a fresh reboot, with Firefox consuming about 8 GB more than it reasonably should, with only three ish tabs loaded.

When FF (113.0.1) is maximized clicking on the first (left hand) pinned tab does not open the tab. Hovering over the tab doesn't change the background color of the tab.

If I restore down the window, hovering over the tab changes the background color of the tab from light grey to a slightly darker grey and clicking the tab opens it.
