Firefox-Hilfeforum

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

Having used Firefox for some time, I installed it on a new PC, and found that virtually all my emails on a particular account seem to have been deleted, despite the app being set up to retain them. I checked on the webmail (BT) and they have gone. The account is set up as IMAP - as is another account on the same server, which seems OK. BT won't engage with me on this as they "don't support third party apps" I assume that 3 years worth of important client history is gone for ever? Can anyone suggest what I did wrong, or is this a software failure?

Here is the video. You can see endless loading of website and in same time I can open it in other browser. Have same issue in two different Samsung Galaxy phones

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

Your Firefox profile cannot be loaded. It may be missing or inaccessible

on debian 12 linux

I tried `firefox` `firefox-esr` `thunderbird``firefox -P`. I also deleted `~/.mozilla`, `firefox -p presaved-profile-dir` stay the same.

the `firefox binary` and the `profile dir` are all useful because I saved them to zip file and use them every day. So is there any other dir besides the 2 dir which fails the startup? even thunderbird fail with the same reason.

Help please, thanks!

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.

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.

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

Firefox opens blank tabs when following link on existing logged in websites, for example Screwfix. Worked previously, suddenly stopped yesterday. Refreshed Firefox, no change. Re-installed Firefox, no change. Site works fine in Chrome and Edge, so not site error, internet error, PC error, or network error. Please help? Thanks, Mark

[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?

The right pane on google drive is not loading on firefox. It says "Couldn't load, Try again". Dev tools show the error "NS_ERROR_INTERCEPTION_FAILED".

If i clean the data and cookies for the website it starts working but not for long. Last time i did it i lasted like 5 minutes. Turning off all the extensions doesn't help.

I'm logged in on several google accounts, don't know if that matters.

After update to 115.2.1, FF crashes at startup for one User, but not the other. FF Safe Mode also crashes (SHIFT key). I tried running the 115.2.1 install on the problem User, but it also crashes right after completion. The second user is handicapped, so I have yet to try to uninstall/reinstall because FF runs on her User and I hate to screw things up so that she is locked out.

• • • JUST NOTED - Chrome also crashes with same NTDLL error (same DLL version number). Did the FF update do something with the NTDLL file?

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.

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.

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.

Any information regarding the issue I'm experiencing here https://stackoverflow.com/questions/77130133/awaiting-on-multiple-api-calls-using-javascript-fetch-api-does-not-work-as-inten or where I could post this issue to get more information on it.

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.

Hi, Recently updated Firefox, and also migrated to a new machine. FF seems to be working fine on new machine, but absolutely unresponsive in loading on old machine, despite problem solving in safe mode, cache clearance, and refresh, as well as re-install.

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.
