Firefox 技術支援討論區

Hello, My firefox has been randomly exiting for a longer time now. (I reopen Firefox it restores itself without any crash info) I've already tried reinstalling and using the cleaning tool. Now I wanted to remove my Addons, but one of them isn't deletable. It also has no name displayed which confused me... Furthermore, there are only "InstalTime12345678"-files in the crash reports directory (which I think aren crash reports). It seems to me the mysterious addon is installed through the policies. (I have a screenshot attached and uploaded them https://pastebin.com/59wzMDyv) This is my private computer and I never set those. Has anyone seen this before or can help? Thanks

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

I want to select multiple Tabs from a bookmark folder to open in the background.

On Chrome this used to be quite easy: Just open the Dropdown, click whichever tabs you wanted to open with the Mousewheel and done.

On Firefox you need to enable new tabs to open in Background first. I managed to find the setting for that with google after a while. You need to go to advanced settings by typing about:config into your url bar.

Then you search for browser.tabs.loadBookmarksInBackground and click "enable".

But this didn't fix the other issue I had, that the dropdown menu always closes as soon as I click anything.

Is there a way so it stays open until I'm done selecting the pages I want?

How do I create a TLS 1.0, 1.1 exception in Firefox 100.0+ for my legacy devices (NAS), that no longer get firmware updates from the manufacture, that are on my private network and thier configuration is done through a web browser?

 I have been using Firefox browser for a long time, since it was called Mozilla browser.  An answer such as "I'm out of luck." means I will have to look for a new browser.  I prefer not to do that.  I trust the Mozilla brand and like you products and recommend them to my friends and customers.

I am reinstalling Windows\Firefox, and would like to hide\remove Bookmarks Toolbar & Other Bookmarks, as shown on the images. The Delete Folder option is greyed out for both, and Other Bookmarks is empty.

Both were hidden\removed in my original installation, but I can't remember how I did that. I've seen posts mentioning e.g. browser.toolbars.bookmarks.2h2020 (it doesn't exist) in About:config, right-clicking on the Other Bookmarks and uncheck it (it doesn't exist).

I'm using Firefox 101.0.1 (64 bit).

Audio was working fine until recently. Now, firefox has no audio playing on any site.

Some sites show "PLAYING" in tab, but others like YouTube don't show that notification. Even with "PLAYING", there is no audio output.

I checked Windows settings and Firefox is set up correct (and the same as it was before it stopped working), see screenshot attached. Otherwise, I restarted Firefox, tried it in troubleshoot mode, and reinstalled Firefox. No changes.

Possible system changes include: Maybe a Firefox update occured and broke the program? I installed the game Civ5 from Steam which required some Windows VS redistributibles installed.

I have tried all of the suggested solutions here at Mozilla for how to delete a website URL from being autofilled: whenever I type 'pre', the autofill function fills in the rest of the website 'www.preply.com'. It was a horrible ESL teaching scam website, I only taught through it for a month last November then quit when they ripped me off. But now since last November, any time I type in 'pre'–I invariably see their annoying, shitty website :-( It is very annoying because it was a bad employer experience–and now I cannot ever remove them from Firefox :-(

I tried deleting it in the address bar with shift + delete, then also went into some obscure Firefox folder and deleted some file with Firefox closed (this was the supposed "solution"–it did NOT work).

Is there any way to solve this incredibly annoying issue? Or should I just switch to Chrome or Safari and give up? Very disappointed in how impossible Firefox makes deleting autofill URLS, really, REALLY BAD software programming. Any helpful or solution greatly appreciated thx :-)

Lately I refreshed Firefox so I can boost it's performance cause it was running just a little bit slower than usual. Since than YouTube does not remember my selected resolution. Every time I close the tab, in the new tab it will have a much worse resolution and I did not have a problem until now. I am a system administrator and I'm currently learning programming as well, so I tried a lot of things to try to overcome this problem. The only extensions I have is Bitwarden, uBlock Origin, Cookie AutoDelete. And yes, youtube.com and *.google.com IS added to cookie AutoDelete. But even without it it's not working.

I have provided the Troubleshooting Information from about:support: Click Here for Troubleshooting Info

I also know that there are extensions like YouTube HD or Enhancer for YouTube what would solve this problem, but I would like to keep my extensions as minimal as possible.

Thank you!

A website MultiSafepay.com has saved my CVV number in Firefox.

How do I edit the autofill data?

I can't get to the same payment page, to be in a position to delete it.

Most links on this matter refer to:

 Options => Privacy & Security => Forms and Autofill

However in my Version: Firefox 98.0.1 (64 bit) running on an up to date Windows 10 this feature is missing or deprecated.

Can anyone say how I could edit/delete this specific entry, or point me in the direction of where this data is stored?

In the mean time I can't recommend using Firefox for entering critical security data, where websites can allow the storage of CVV numbers.

Using Mac OS 12.4 and Firefox 101.0.1. After launching Firefox, a second icon appears in the "recently used" apps section of the Mac OS dock (see attached screen shot). The icon stays there and goes away, and then comes back, and then goes away, etc. This continues on and on until Firefox is closed.

Why is this happening? Never acted this way before the latest updates.

My bookmarks have been broken up in the categories for years... ie: Research, Health, Shop, Weather, News, YouTube, etc. Suddenly today the News tab is missing from the Toolbar??? I can't find it when I search in Manage Bookmarks. Where did it go and how can I get it back???? Help!!

Hi there

I've had firefox for years and never had much issues. I've never had this issue before the most recent update where now youtube videos constantly stutter. It's just Firefox as other browsers work fine. I've updated my graphics card and did a little bit of research but none of the fixes quite did it for me. In the past couple days I've always had Firefox crash on me twice, which hasn't happened before either. So I'm not sure what's going on, but I'm prone to point fingers at an update. I don't install extensions or themes, so the only extension I have really is uBlock Origin but that's been there forever. I've restarted my computer as well. It is not my resources, they are more than fine my RAM and CPU and Graphics Card. Task manager shows nothing is even above 50% (CPU, GPU, Memory) when playing the video. I've also tried creating a new profile and opening up a new profile. Same issue.

Can anyone suggest any fixes or is this a firefox update bug?

EDIT: This appears to be for all videos I am playing on Firefox. It also does not matter if I set it to the lowest quality, even 144p, it will still stutter nonstop.

For some whatever-reasons (TLDR; I need to see the whole domain (including subdomains) clearly, unlike the default of only highlighting the TLD&second-level domains[1]) I want to disable the color-distinction which highlights TLD and second level domains.[2] Is there config to do so? If not where should I propose one?

Thanks.

[1]: for example ko.wikipedia.org and en.wikipedia.org will have wikipedia.org highlighted, and that's what I can't accept because ko.wikipedia.org (Korean) and en.wikipedia.org (English) is completely different site. (Some might say you can distinguish by language, but there are some English sites which shares the same domain on wikimedia.org, so you get the point here.) [2]: From the screenshot you can see only `wikipedia.org` is highlighted. I want to make it highlight all of en.wikipedia.org. (If I need to highlight everything including the site path below the TLD, I can accept that.)

Why am I denied access to Michaels craft store. this is the message I receive. You don't have permission to access "http://www.michaels.com/?" on this server.

In the last few weeks Firefox will not open even when using admin rights. NOTE: I have followed all available posts including multiple uninstalls (complete), deleting Firefox folders, reinstalling, etc. There have been no major (or known) changes to my Windows 10 Pro system. I run Heimdal Thor and Kaspersky antivirus protection and there have been no conflicts running both at any time. I also use Acronis Protection (I know it may seem like overkill but it works). I have turned off each of the above and Firefox still does not open. Firefox runs with no problems on my personal and work laptops. I am CompTia A+ Certified so somewhat knowledgeable (a little knowledge is a dangerous thing!) and have run sfc /scannow with no issues noted. Plus, two Heimdal support reps have logged onto my system, attempted to find a solution, found no issues with my system (Omen 880 even though I don't game). My wife is a dedicated Firefox user and wants it back.
