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:

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.

I'm not really sure how to categorize this question, so I labeled it Other.

I use Firefox v118.0b9 with Windows 11 and the clipboard api works as expected. However, I have a friend in Denmark that uses Firefox v117.0.1 with Windows 10. He tells me that the copy to clipboard function that works for me doesn't work for him.

Anyone using the same version as he is can check it out here:

There are 5 buttons with copy icons. Each copies a specific puzzle solution or the puzzle itself. Is there a reason it does not work with that version of Firefox but does work with the version I use?

Hello,

After Windows11 last udates, audio disabled in only the Firfox browser (such as when using Youtube and all other audio included sites) while audio working properly in Microsoft internet browser and in rest of my PC apps, I tried many ways including update firefoxB , tweaking windows11 but all with no result.

Thank you

I am using https://infiniteajaxscroll.com on my website https://madway.net . When I scroll down and new set of topics loads, if it contains html5 video it will not load, stay loading. Works fine on Edge browser and Android browser.

Using latest Firefox.

My Firefox tab crashes often. I eventually need to reboot Firefox. My Windows 11 patches is always up to date and I did system checkups often. I cleared cache files too.

I have been running into an issue any time that I try to open Firefox, I recive a pop up stating "Your Firefox profile cannot be loaded. It may be missing or inaccessible."

I have tried all of the suggestions noted within the Mozilla support and documentation.

I am running Windows 11 and was using my machine normally. I cleared the cache within Firefox under the settings and was able to use the browser for 20 more minutes without any issue. I tried to open a second Firefox window and received the Profile Missing error. From here I closed out instance of Firefox which I had open and tried to open up Firefox again. I was greeted with the same "Profile Missing" error.

When I navigate to the location of the Firefox profile (%APPDATA%\Mozilla\Firefox\Profiles\) there exists a profiles.ini file along with a "Profiles" folder.

I have tried deleting the profiles.ini file, as the Mozilla documentation says that doing so will cause Firefox to generate a new profile, however after doing so I continue to receive the "Profile Missing" error.

I am unable to access the Profile Manager within Firefox to make changes to a profile or create a new one as stated within the Mozilla documentation, due to the application being blocked by the "Profile Missing" error causing the browser not to open.

The about:support page under Media section is showing incorrect values for available decoding capabilities. My GPU is MSI GTX 970 and it doesn't support VP9 and VP8 decoding. I verified it by analysing video engine usage. My OS is W11

I don't know when it started (quite awhile), but when I go to some websites even in FF safe mode, I wait a long time but get nothing displayed and it stops spinning/waiting (the circle arrow upper left stops). Occasionally when I reload, it comes up but usually it doesn't. Other websites it works fine.

In fact, if I browse to some websites, sit and wait awhile, then go to chrome or edge, type in the same website, the page displays even while FF is sitting there waiting.

ebay.com seems to work great, but for instance this morning, this one doesn't: https://www.crowdpac.com/news/741938 but sometimes this works: https://www.crowdpac.com then try it again (refresh) and it never responds.

And in fact, I'm using Edge to submit this question because when I browsed to https://support.mozilla.org/en-US/questions/new/desktop#search in Firefox/Safe and clicked on the Sign-In/Up button, nothing happened. With Edge it worked fine and I'm able to type this in.

Hello,

I have problem with google search in firefox on my PC. I get a lot of results but when I want to open it it does happens nothing. If I try to open in another window I get redirected to a site which begins with https://www.googleadservices.com/pagead/.... This means I cannot use search function. Is there anything I can do to fix this problem? Thanks Yvonne

I bought a new computer a few months ago, and almost instantly I noticed that video playback had a problem. I installed Firefox, but if I replayed a video, the audio was noticeably off from the video. The problem is resolved if I tug on the progress bar, but any playback on Youtube is affected. I do not have any extensions on this browser, and the problem does not present if I use Edge, or the sort. I can not say if playback is affected on other websites, as I do not have that much need of my computer beyond the basics. I would rather not change browsers, but I have not discovered any suggestions of related problems that relate to my computer.

Ever since switching to Windows 11 I've had an issue with Firefox. Any time I copy something in Firefox, be it image, article text, or even a url from the address bar, I cannot paste it anywhere, and my copy and paste stops working. The only way to fix it is to close Firefox, and then run rdpclip.exe as an administrator. I've confirmed the issue only occurs if I try copying from Firefox, as it doesn't happen in Edge.

Does anyone know what might be causing this. It's very frustrating.

[Windows 11 22H2, Firefox 117.0.1 (64-bit)]

i often have a Main and Private window open concurrently. All too often the Private window will close while Windows is locked - Sleep or Hibernate - but the Main window always stays open. The results range from annoying to extremely aggravating.

Other than saving the open tabs as needed = assuming I remember, to reopen every time this occurs.

Why is this occurring, and h9w can I fix it?

I use two monitors, and I have multiple firefox windows open at once. When I turn on my pc and open firefox, the windows almost randomly position themselves on both monitors, sometimes they are not maximised either. How can I change this behavior so that all my firefox windows open, maximised, on one monitor rather than both?

I need to install Firefox on a new laptop under an existing account, but a new account was already created on the new device. All it will let me do is reinstall under the newly created account.

Please HELP -- I can no longer use Thunderbird or Firefox to access my emails at the University of Vermon (UVM). For over about 2 months after the Univ. of Vermont went to a new email system, I can no longer use Thunderbird or Firefox to get my emails. I get an error message when I enter my NetID and password at

The "Digital Advisor" page on vanguards website (after logging in) seems to default to a white background even when in dark mode, resulting in the page being unreadable due to the light gray/off-white text. It seems to only be on the digital advisor page, though. When viewing other accounts or sections, dark mode seems to work correctly.
