Firefox 技術支援討論區

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.

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.

As per subject. After i close FF - and it is no longer showing as an app in Task manager. When i try to restart it, it says it's still running and i have to ask it to close FF before it will open it again. AFAICS It happens randomly.

It may be relevant that when using CCleaner, it often (randomly) hangs when cleaning FF internet cache and says FF needs to be closed when it is already closed and does not appear in task manager. If i ask CCleaner to close FF, the application hangs.

Less likely perhaps to be relevant: i got a rogue change of Favicon on one site. I eventually deleted the relevant file hoping the Favicons would repopulate. Most have, but many haven't including hotmail and protonmail sites.

There seem to be many causes/solutions to FF hanging but i thought these specific circumstances might make it easier to suggest what the problem is exactly and how to fix it.

Thanks.

Hi, I get the below error message when trying to login to visma.net (for work).

json.parse unexpected character at line 1 column 1 of the JSON data

On this note I have a previous error, loggin in to this site that was fixed by a support member (• accessibility.blockautorefresh = false), but I have the above hurdle left. I can get past it by clicking backspace but thought there might be a better solution - maybe some other setting I can adjust similar to the first fix I got help with.

The web address for this error message shows as: https://api.home.visma.com/home/rest/sso/login

hello. I have a reproducable issue with Firefox. If I use the touch keyboard on Firefox and then exit Firefox without without closing the touch keyboard, when I next start Firefox it only opens with a half view. if I close the touch keyboard first and then exit Firefox it opens as normal in a full screen view. it has nothing to do with either an extension or a theme. is there any way of ensuring that FF opens in full screen view if I forget to close the touch keyboard before exiting the browser? thanks in advance. PS: device is a Surface Pro 7 running Windows 11.

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?

Please HELP -- I can no longer use Thunderbird or Firefox to access my emails at the University of Vermon (UVM).

Hi! I have two Firefox accounts, one for work and one for personal use. I often have them running on the same computer at once (this does cause them to crash occasionally, but not often enough to be a problem). However, today I tried to log into a website where I regularly do freelance work and received this error code: "Error code: SSL_ERROR_PROTOCOL_VERSION_ALERT"

I would assume something was wrong with the website itself, however when I went to that same site on my other account, it loaded just fine. I've restarted my computer, restarted firefox, deleted cookies and caches and browser history, but still get the same message on my work account. Any idea how to fix this?

Thanks!

Basically as the title says. The only sites this is an exception for is youtube as well as big streaming services but on youtube the video seems like it takes longer to buffer and has a lot more pauses.

I am on Version 117.0.1 which was installed on September 12th for me. I did not notice any issues prior.

I am on a macbook air which is updated to latest software.

I have tried the following:

Running it in troubleshoot mode. It did not fix the issue.

Turning on/off autoplay. It didn't work.

Clearing cookies/cache. Nothing.

Started firefox without a theme. Didn't do anything.

I unchecked "Use hardware acceleration when available." which did nothing.

Sites I have tried watching videos on include:

reddit

pornhub/other porn sites (for testing purposes...)

instagram

Vimeo

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 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.

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.
