Firefox 技術支援討論區

Hello, Firefox randomly downloaded a file, with seemingly randomly name, that is 0 bytes and in download manager the source is moz-safe-about. It happened when I was accessing a popular wiki site. I opened the file in notepad, it was empty. I put it on virus total and came back negative, as it is an empty file. I've curbed through the support tickets here, using the keyphrase 'moz-safe-about'. I understand this was/is quite a common problem, but it still makes me quite worried and left a sour taste in my mouth, as I haven't understood any of the explanations. I have enabled firefox to ask me whenever it wants to save something (I have no idea why this isnt the default state). Happened on a somewhat fresh, updated win 11 installation. I'm also attaching more information here with a picture. Long story short: should I be worried? Am I overreacting and this is just some sort of a bug that occurred while getting a sites data? Thank you for your time.

I cannot open any Games on the NY TImes site with FIrefox for the past month; no problem with Chrome. Today, two article links opened but then the page went blank (repeatedly), while other links worked fine. Again, no problem with Chrome. My wife can't get into proxyvote.com with Firefox--again, a blank screen. Where is this weirdness coming from?

Hi Friends.... This morning logged into my website as usual and this message appeared on the home page. I have not checked the link as it seems potentially malicious ... It does not appear when visiting my site on Safari. I have emptied the cache I have been through troupbleshooting mode I have reinstalled Firefox and it still is there..

How to rid myself of this

All help gratefully received Graham

Macbook pro 2017 OS 12.7 Firefox 125.03

I'm having trouble using a particular site, that I used to be able to in particular clicking on sub menu's from a context menu if that is the correct term, meaning I cannot click an item/button to reveal a menu below it. From the image supplied there are 2 'menu's' with a < character that when clicked should reveal a sub menu of items, works in Edge/Chrome etc.. the only extension I have is Keeper.

My yahoo homepage on firefox looks totally different than it did last week. Chrome and edge still look like the home page should but firefox does not. I screen shared with yahoo and they said it was a firefox issue. Anyone know how to make the homepage look like chromes and edge? I added pics from edge and firefox for comparison.

Howdy,

Workflow: I have a firefox instance already running. I want to launch a new firefox in safe-mode to test something without disrupting my existing firefox.

Problem: I try to launch a new firefox in safe mode using `firefox --safe-mode`, but firefox just opens a new window NOT in safe mode.

I think it may because firefox in safe-mode requires launching launching from a new instance rather than attaching to existing instance.

`firefox --help` shows a flag I can use:

--new-instance Open new instance, not a new window in running instance. --safe-mode Disables extensions and themes for this session.

So I run `firefox --safe-mode --new-instance`

now I get error popup with message:

"Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

Now I think what is the point of the flag "new-instance" if Firefox doesn't support multiple instances?

Regardless, how can I launch firefox in safe-mode without disrupting my existing firefox instance and without relying on creating a profile just for this?

I have enabled Firefox Sync between my laptop and my Android. When I go to the manage history tab on my laptop, the history of both my laptop and phone is shown but without the device the tab was viewed on. Is there a way to filter history based on which device I viewed on?

Firefox sometimes continuously adds tabs for the same site I am using. Every time I X out of one, another one pops up. This multiplies alarmingly fast. I have Windows 10.

I use a MacBook AIr with OS 14.4.1 (Sonoma) and want to add a short cut link to Proton Mail (Free version) that I can put in my MacOS Dock. I am using Firefox 125.03 version.

I used to have a link in my Mac Dock but then I tried the trial of their desktop app-- and when that ended recently, I did not know how to set the Dock link up again. I tried directions for other browsers but they did not help.

'The link I want the short cut to go to is' https://account.proton.me/mail so I can sign right in to check my email.

So I checked Proton's support site for help but it has directions to do this ONLY from Safari and another browser, NOT Firefox.

If you can give me some straightforward directions to add the shortcut to Proton Mail sign in back to my Mac Dock, I would be grateful!

I really enjoy and feel safer using Firefox, by the way! thank you

Hi I am a longtime user of your browser. I have version 124.0.2(64 bit) installed on three devices. First thing I do on opening it is to click on "about", which normally updates the browser, before I do any browsing. In the last three weeks, however, it has not updated on any of the three devices, rather, it says "Failed to check for updates". I have tried the workarounds suggested at your Help center, and nothing has worked. What gives, may I ask? Thank you

I use google as my default firefox home page on my HP laptop. recently a second tab opens at the same time. "how to set the home page" --I've tried closing it and restarting the laptop, but it continues to pop up every time I open firefox as a 2nd tab. I am/was happy with my homepage opening to google. How can I get rid of this second tab. thanks

I've been using Firefox for about six months. I'm a MacBook user with the most recent version of Sonoma installed. After a month or so of using Firefox it starts crashing and freezing. Sometimes I can't restart it for several minutes. Whenever this happens, I refresh it. I've refreshed it about twice. I've re-installed it twice too, but it keeps happening. Most settings are default, but I wanted to include the settings in case this could be the problem: - I've turned off Firefox home content - I've turned off all passwords and autofill features - Never Remember History - Do Not Track and Tell Websites not to share/sell my data are turned on - I left the standard-level security settings as is

I have one extension installed.

The only other browser I have installed is Safari and I am not having these issues. I should add that I don't receive any error messages when this happens, it just freezes. The most recent issue is that I was clicking on buttons on a website and it wasn't working, but when I started using the Safari browser (which also set to private mode) it worked fine.

When it works I love Firefox and would like to keep using it. I am wondering if there is anything I can do to fix this.

I have Windows 11 and Firefox 124.0.2. Firefox keeps asking to reinstall. I think it is because I keep getting the message that it fails to check for updates. I don't know if I have installed the Microsoft Firefox or the direct Mozilla Firefox downloaded. Maybe that is the problem, but I am not tech savvy. I have used Firefox for many years and like it. I am also too old (83) to deal with these problems. Help!

something apparently got corrupted in firefox.. i tried running update and i keep getting failed to update.. i have refreshed.. i have uninstalled and reinstalled ...nothing. i am sure there is a folder or file somewhere that is corrupted and i cannnot find it. because even when i uninstall and reinstall fresh. all my bookmarks are there .. how to i start a TRUE NEW install??
