Firefox 技術支援討論區

Currently, Firefox opens OBJ files as text. I want to send them to the Microsoft 3D Viewer which is the default application in Windows for these kinds of files. All I can do right now is right click on the file, save the file, then open with the 3D Viewer. I have gone to settings/General then down to applications and I can't add any files there. (Why not?) It doesn't matter if I choose to save or open files, the OBJ file still displays as text in Firefox. How do I get Firefox to send instead of display these files as text?

I've hit a crazy problem:

I open firefox and browse to a website. Close Firefox and then reopen and attempt any website and it just hangs. Close the browser and look at task manager and it's still listed - end task open again still no connection to anything. Have tried the Read Only thing in %APPDATA%\Mozilla\Firefox\Profiles\ after a restart of the PC and it stays Read-Only even when I change it. Have tried a new profile which just moves the same behaviour to a new profile ie create a new profile open the browser go to any website, close the browser and reopen and get nothing. I have repaired, uninstalled, reinstalled and I just can't get it to work unless I restart the PC everytime i want to go to a webpage! Anticipate switching to Google Chrome soon if I can't find a solution which is a shame as I have been a Mozy fan for years. Any suggestions?

When i open https://provider.transporteg.com/ this website and login in the portal this is not showing the bidding running time and processing time . please solve this.

Hi folks,

I run a server which is ONLY accessible from my own IP address. I have a particular script on that server which deletes certain log and temporary data files at the end of a job run. I have a problem where those files being deleted WITHOUT me visiting the page !!

Somehow Firefox appears to be randomly visiting that page all on it's own, without a window or tab open which is then deleting the files at the wrong times without me doing anything.

I have put some tracking in the script and the http request is DEFINITELY coming from my IP.

The user agent is being reported as: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:109.0) Gecko/20100101 Firefox/115.0

The page address is not being recorded in my browsing history.

How is this happening ? I only have 2 extensions installed: Tab Reloader and UBlock Origin.

Is there a way to track ALL activity that Firefox is doing so I can trace where this is coming from please ?

I'll point out that to my knowledge, this is ONLY happening on this specific page on my own server and not anywhere else that I am aware of. All my other scripts on that server have tracking as well, but none of them have been randomly run.

I need to track this down as right this moment I have the original script renamed and I'm having to use £%~£%&{ chrome to run it as I cannot trust FF NOT to run it !!!!

Any help would be appreciated.

I am currently using Ubuntu 24.04. I recently switched from the snap ubuntu package to using the firefox APT package. However, I've noticed this really weird issue. Whenever I download a file, it always seems to have the "file://" link or mime type.

Say for example I download an mp4 video, trying to open it via firefox results in a dialog asking me to "select which application i want to open this file link in"

I have tried refreshing firefox, and tried completely removing it from my operating system (a search of my entirety of / showed no traces of anything relating to firefox), but even after a clean install, the issue persisted.

The only way I found that can fix this issue is by using firefox nightly, or using the firefox flatpak. And I'd prefer to not use either.

I was monitoring the browser console, and upon clicking on the file in the downloads list, It seems that firefox gets this error:

Uncaught (in promise) TypeError: defaultButton is undefined

   _setInitialFocusIfNeeded chrome://global/content/elements/dialog.js:318
   _postLoadInit chrome://global/content/elements/dialog.js:332
   connectedCallback chrome://global/content/elements/dialog.js:149

dialog.js:318:9

This error does not occur on firefox nightly.

I believe I have troubleshooted this as much as possible on my end, and I'm unsure of what to do about this. Could I please get a bit of help?

Versions: Firefox: 127.0 (64-bit) Linux: Ubuntu 22.04.4 LTS

Description: After some time, and (under unknown conditions), the input delay will shoot way up. Like 20-30 seconds.

Strangely enough, this only applies to keyboard inputs. I can change my tab with my mouse, I can click on things, no issues there. But any keyboard interaction is hugely delayed.

This does not fix itself until I close my browser and restart it. Closing the browser is always broken here too, if I close the browser with the [X] exit button, I then need to kill the process because it just hangs. It blanks out the contents of each tab like it's preparing to close them, but it just doesn't ever complete the task without a manual kill.

CPU usage and memory usage are relatively low; significantly below my system's limits.

I've already tried this suggested fix, to no avail.

The frequency of this is only about once a week at most, usually once a month, so it's not a huge issue, but I'm just worried about this occurring during a critical meeting or something later. Having this impending restart needed is kind of worrying for critical usage times.

Hey folks, I've been noticing something peculiar with Firefox that's been bothering me lately. Whenever I try to watch videos on YouTube in resolutions above 1080p, they tend to randomly buffer. It's quite frustrating, especially when I know my internet connection is stable and other browsers don't seem to have this issue. Has anyone else experienced this problem with Firefox? And if so, do you have any tips or solutions to share? Thanks in advance for any insights!

I'm working on developing a website that uses WebGL in it, but sometimes some bad code will cause WebGL to crash. The issue here is that once that happens, I have to go into troubleshooting mode and back out before it starts working again. Is there any way to make it so that WebGL works after it crashes?

ever time i watch something i will go to pause it and noting will happen and if hover over a video and preview it won`t stop until i close the tab how do i turn this off?

Greetings,

I'm a user of Mozilla, it's my main browser. I use it for everything and especially for Youtube. But, recently, some changes have appeared and not for better. I don't know why or if it's only me. The thing is Youtube is not like the real site but something else and so i lose options or settings. I don't have anymore the mutiple screen size options. There's a button that says "watch this on Youtube" while i'm litteraly on Youtube.. And now i want to watch a video with a age restriction and it'tells me i have to be connected to Youtube while i'm connected.

Can someone answer me about this or make it noticed by Mozilla employees ?

Thanks

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

i use Firefox as my browser, but AT&T Yahoo is my internet provider so I use a Yahoo home page and Yahoo mail. Last week they did an update, now every time my laptop goes to sleep I have to re log into Myyahoo to get my mail and my home page. It also seems to log me out of some of my other forums and websites at the same time. I'm not sure how to fix this in settings so any help would be great.

I'm on Firefox 127.0 (42448) ios and all my private tabs were closed on update and now whenever I make a private tab it disappears after the app is closed or refreshes. It's kind of behaving like the setting where private tabs are closed automatically but when I looked in the privacy settings of firefox ios it's not there anymore. Does anyone else have this issue? I know theres an existing problem with tabs for firefox but I don't think this is exactly the same because my normal tabs are totally fine.

The behavior began with fifteen to twenty crash messages appearing. After which the browser would stop responding and be unable to reach out to the internet.

Network connectivity was confirmed as I was able to access my VPN and corporate teams.

I submitted as many crash reports as I could. Eventually the crash reporter ceased to function. The message is:

Firefox had a problem and crashed. Unfortunately, the crash reporter is unable to submit a report for this crash.

Details: expected value at line 1 column 1

Only a full reboot of the machine restored functionality but only temporarily. It returns after being put into sleep mode.

Running firefox in safe mode does not restore functionality. The behavior persists.

I am fully up to date according to firefox.

I am running a Lenovo Thinkpad Windows 11.
