Firefox 技術支援討論區

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 have the same issue as stated in https://support.mozilla.org/en-US/questions/1390122?page=3

How does it come that it is still present in 117? Why is there no official guide or warning about this issue? I am forced to use Portable 101 where there are no such bugs. The solution in the thread is unclear and points to Microsoft, which is ridiculous. The question is how to solve that Mozilla's bug?

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.

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!

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?

Using Firefox 17.0.1 on MacOS Ventura 13.6 on my 2017 iMac I am unable to connect to the internet while using Private Internet Access (PIA) VPN. All was working normally until I installed MacOS Ventura 13.6 yesterday. The VPN works normally when using Chrome or Safari. I have tried changing my network proxy setting without any luck. The default setting is "Use System Settings", using No Proxy or Auto Detect Proxy doesn't help. I don't see a switch for Enable DNS over HTTPS. All works fine when the VPN is disabled. I tried deleting the VPN a couple of times then reinstalling but that didn't help.

What am I missing here? I have used this VPN for years without any issues & it worked on Firefox until I installed MacOS 13.6...... using 13.5 I had no problems. Any suggestions or thoughts would be appreciated.

Thanks...... Brad

On a site with a menu along the top the rightmost item is missing, and only in Firefox, not Chrome or Edge. It happens on various pages with the same menu setup. I cleared cookies & cache, turned off extensions, no luck. See attached image. What could the problem be ?

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.

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.

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

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?

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

I just purchased bose 700s and I can hear noises for a fraction of a second every time I move the video forward beyond what is already in the buffer. On chrome the scrubbing is perfectly fine.

It is really annoying, any help? Thanks!

pd. I noticed this doesn't happen with another pair of headphones so the 700s in themselves play a factor. However it never happens when using chrome so I guess is the combination of the two-

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!

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.

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.

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

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.

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.
