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.

Ever since FireFox updated to the latest version I'm constantly having Tabs crash within Firefox. The following message comes up: GAH. Your tab just crashed..

Hello! I have a problem with latest version of FireFox (118.0.1). I have a website running at https://localhost:7230. And Asp .Net Core backend running at http://localhost:5205/, the authorization is configured to use NTLM.

From the frontend I call: const response = await axios.get("http://localhost:5205/Users/GetUser", {

   params: null,
   withCredentials: true

});

and it works in Chrome and in previous FireFox 117.0.1, but doesn't work in FireFox 118.0.1.

I've checked the request-headers, they are the same except for the version in User-Agent. I guess this has something to do with the security settings. I looked at the patch notes but didn't see anything similar to my problem.

What was changed in the latest version and how can I fix this?

right click menu copy not clickable,cant copy but when I hit ctrl + c and copy something first then i can copy within the right menu fine with the same site, and no this is not a site issue chromium works just fine.

Good afternoon. For the last day or so my Firefox has been running slower than normal. It takes longer to load my home page than normal, for one example. Actually it takes a little longer than it had to load most web pages. I tried opening the same pages on Edge to make sure it is not just an internet issue and Edge works fine.

I am also having an issue with settings. When I open settings, privacy, and navigate to saved logins before when the list would automatically populate it now takes almost 12 seconds to load all my logins.

I did try to run the browser in troubleshoot mode and the behavior did not change.

I am running Firefox 118.0.1. Any help would be appreciated. Thanks in advance.

When copying text from a website in one Firefox window, and pasting in a separate Fire Fox window, formatting issues occur

• Running on Windows 10
• Firefox, windows/tabs not in container
• Pasting text from Coursera to Notion.so fails to start text on current line and properly format.
• Works on Microsoft Edge with no issue, so problem is isolated to Firefox

Attaching images for clarification and comparison. (sorry for quality, quick MS.paint job)

• after further testing, it appears that copying from Coursera in Firefox to Microsoft Edge also has the same formatting issue, so it seems to be a compatibility situation between Firefox copying from Coursera specifically, and not an issue with pasting to Notion.so

• appreciate the fact that there are multiple third party factors at play, but the issue is killing my productivity so any help is appreciated!

When I am streaming TV shows or movies online using Firefox the timer in bottom left corner is is not going up by one. It seems that since the net framework updates in the past 3 days have updated in Firefox which is now causing my computer to act like a virus. The show will glitch and repeat 2 to 5 seconds worth of time. Seems you all need to check your crap with Microsoft to update your Firefox.

I cannot stream china open tennis via tennis tv - login problems, crashing problems. Unresponsive to login details Sometimes I can log in but then cannot open specific matches Other times the screen just goes blank There is an account login icon in lower left hand corner of the screen, but if I try to refresh the screen the icon changes its nature and does not respond, then I cannot log in or out It is random and unreliable when I am trying to stream the tennis I have never had this problem with this website before, and I have been a subscriber for 5 years The first two photos are how the login icon should look. The third shows what is happening to the login icon The fourth photo is the blank screen that I sometimes get and cannot move away from - the screen is stuck I really dont want to have to use Safari and definitely not Chrome Sherrill Carta shcarta@gmailcom

When I try to connect to the Etsy website I get the following message "429 Too Many Requests". I have a VPN and I have to turn it off to be able to connect. I contacted Etsy and they said it was a browser issue. Besides turning the VPN off when I want to connect is there a fix?

Speed test on a freshly booted machine is 100/100Mbps ... very often after viewing a youtube video in Firefox, this Speed test can slow down to below 20Mbps which results in a poor streaming experience ... I have a 150/150 fiber connection and the modem speed test doesn't change ... nothing to do with anything downstream ... not running anything else except FF ... always running with the latest up to date version(s) ... things of note: the process count goes up when this occurs ... even if FF is restarted it doesn't resolve this issue ... only a reboot resolves the issue ... when rebooting there is always some UNKNOWN process that needs to be manually terminated before the reboot process runs.

I suspect one of the multilayered (FF appears to open multiple sessions with streaming) processes may be getting widowed and left running and not releasing resources which causes less and less bw to be available ... this appears to occur mostly if I either Fast Forward or try to click forward or backward on a stream timeline suggesting to me that the current timeline may not be closing properly ... process manager doesn't reveal any processes linked to firefox but there are numerous svchost processes which I expect may be involved

Are there other ways/tools to narrow down this issue so the Mozilla team might be able to fix this ... I use FF exclusively but this has become more and more of an annoyance.

My i7 2TB 2.6GHz 8GB laptop is unable to move beyond W7 64b pro but I have had the same experience on a W10 64b Pro machine so very skeptical that this is an OS related issue.

Ultimately if FF kept track of the PIDs it opens it should be able to force them to close if they refuse to close on their own. Kill Process tree ... or ... perhaps provide a log that is user accessible identifying opened PIDs so that a user could manually kill widow processes without having to reboot.

This is a recurring problem. I have just been on to Vodafone who have tweaked my router as my speeds, download and upload, were very erratic, and upload speed often zero so connections failed. Sometimes my phone speeds were similar but not always. The Speedtest by Oopla desktop app also showed erratic results but often when they were OK the web-based test on Firefox was much worse, with upload speed zero. When I started this Firefox showed upload speed zero. Now Firefox shows upload 18Mbps. This variability keeps happening and is driving me spare, as even emails often fail to go through - I use Thunderbird. I shall see how things go tomorrow and tell you how it is going.

I contacted you the other day and refreshed which helped somewhat, today It would not come up aT all. I am contacting from edge at the moment. I am very frustrated. Is there a chance I could talk to a live person; this takes way to long?

I'm using my Firefox with Custom CSS with toolkit.legacy thing enabled. I'm using Firefox for my everything and I love it. But It keeps break my current profile then starts a new profile that everything has been reset. It keeps break my profile and starts a new profile. I lose everything... It's enough for me. I could not find any solution for it. If It's not fixed, I'll stop using this beautiful browser :'(

Same as the question.

The display shows some icons on the last tabs I opened but it seems only some basic website layout is loaded but all the details are gone. Like text, button borders, even the exit, fullscreen and minimize buttons. I have seen that this has been an issue for quite some time before so I am looking if there is a fix or a workaround. I have and Nvidia graphics card and drivers if that means anything. And my swap file is 20 GB and my RAM is 16 so the space shouldn't be a problem. It gets fixed when I turn off Firefox but not when I refresh tabs.

The crazy thing is that when I take a screenshot inside firefox (with firefox integrated screenshot option, like when I press right click and then take screenshot. I can see the text so it seems like it is a display problem but this only happens with firefox and not other apps.

Appreciate all the help. I will ask of ubuntu formums next if I don't find a solution here.

Thank you all for reading and answering!

I'm encountering consistent video playback issues on Firefox while running Fedora 38. The error message I receive when attempting to play videos from certain sites, notably LinkedIn and Twitter (now X), is:

• The media playback was aborted due to a corruption problem or because the media used features your browser did not support.*

Furthermore, when examining Firefox's console while attempting to play a video, I observed the following error:

• [Child 5999, MediaDecoderStateMachine #1] WARNING: Decoder=7fdb3c55a100 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-118.0/dom/media/MediaDecoderStateMachineBase.cpp:166*

Steps to Reproduce: 1. Navigate to LinkedIn or X (previously Twitter). 2. Attempt to play any video content. 3. Observe the aforementioned error.

Additional Details: - OS: Fedora 38 - Firefox version: Initially 117.0.1, then updated to 118, both 64-bit. - This issue does not occur on Google Chrome on the same system. - I have attempted the following troubleshooting steps without success:

 1. Updated Firefox to the latest version.
 2. Enabled DRM content.
 3. Booted Firefox in Safe Mode.
 4. Disabled hardware acceleration.
 5. Cleared cache and cookies.
 6. Used a Flatpak version of Firefox.

This issue has significantly impacted my user experience, and I hope to find a resolution soon. Any assistance or guidance would be greatly appreciated.

Thank you!

Really too much PR_END_OF_FILE_ERROR

https://www.bbc.co.uk/news/uk does NOT have issues.

this error message occurs regularly ( and sometimes with amazon.de)

Please fix the bug that causes this, or allow a option to ignore the (non existent) error.

Hi all, the shortcut to close a single tab (ctrl+W (Windows) or cmd+W (Mac)) is not working anymore.

here is what I tried so far: - disabling all extensions (via restart in safe mode) but to no avail - reinstalled Firefox but the problem persists - verified, that the command is indeed cmd+W and was not changed by accident - all other shortcuts are working well

NOTE: I can see that when I press cmd+W, the "file" tab up above on the Mac menu bar flashes for a brief moment, as if the system detects the shortcut. But the tab stays open.

Any other ideas I could try out?
