Firefox 技術支援討論區

Hi, I've been having problems with my Firefox. After some time (~1 day?) all websocket connections stop working until I restart the browser. In JS console I can see "Firefox can't establish connection to ws://..." (or wss://).

This really affects all pages, for example Discord, Onshape, Jupyter notebook, and 100% gets fixed when FF is restarted.

I'm looking mostly for some debugging tips. So far I've tried increasing `network.websocket.max-connections` from 200 to 500, without any luck. I have also tried to examine some pages for open websockets using developer tools, but didn't find anything suspicious.

I'm running version 110.0.1 built on Gentoo, but this issue has been with me for couple versions already. I have a few extensions, including uBlock origin and leechblock, approximately 100-200 open tabs in 4-5 windows at all times. Restarting firefox every day is not the worst, but I'd definitely prefer to not have to do that

Hi, I have firefox on my Ubuntu 23.04. When i start it it shows a black screen. I click quit on my system and then i startup and it lunches normally. What am I doing wrong or how to fix it?

I use Firefox sync between multiple devices, including a desktop and a laptop on Ubuntu Linux. This is done through a Firefox account. Both Ubuntu devices mentioned run Firefox 108.0 for Ubuntu 20.04 LTS.

I'm signed in on this Firefox account on my laptop (from which I'm writing this message). I recently (some months ago) changed my primary e-mail, since I may lose access to the older e-mail account soon. Now, suddenly, on my Ubuntu Desktop I received a message that I need to sign in to sync. When I click on "sign in", it takes me to tab that lists my primary e-mail address and asks for my password. I enter the password that I know is correct (it is listed under my saved logins on this Ubuntu laptop and the e-mail listed is the primary e-mail address with which I am signed in on my laptop, writing this message; it is also listed on my Firefox account details as my primary e-mail address). I then get a red message on tab stating "Primary account e-mail required for sign in", despite the fact that it is with my primary e-mail that I am attempting to sign in! I've tried it multiple times, to no avail.

At least two other users have posted about related concerns this year: (see https://support.mozilla.org/en-US/questions/1368875 and https://support.mozilla.org/en-US/questions/1395902). However, nothing has been done to resolve this issue. I have followed all instructions provided for changing my primary e-mail address. This is definitely a fault on Mozilla's side and not mine. Please resolve this urgently, users risk losing vast amounts of data, through no fault of their own, if you fail to do so.

2FA login on sites works with Chromium but NOT WITH Firefox (Linux)

Present setup:

Does NOT work firefox 102.7.0esr on debian 11.6 bullseye 5.10.162-1 (x86-64) firefox 110.0 on Ubuntu MATE 22.04 LTS 5.15.0-58 (x86-64)

Works chromium 109.0.5414.119 on debian 11.6 bullseye 5.10.162-1 (x86-64)

I am able to register and authenticate with security devices Yubikey NEO (without FIDO2) and Yubikey 5 NFC (FIDO2 compliant) on several sites (eg. pypi, google..) using Chrome or Chromium but now not with Firefox at all. It has not worked for at least the last few updates. Changing settings in about:config or plugging/unplugging keys, stopping every Firefox plugin etc. don't help. Neither does a fresh Firefox install without any super-security-settings.

Testing sites like Yubico's own or Okta's works fine using Chromium but not Firefox.

From what I can see this is not especially related to FIDO2 (Webauthn). pypi seems to use U2F which should work just fine with Firefox since way back.

I haven't tested Firefox for Windows but Chrome browser for Windows 10 works fine (which I tested first when Firefox didn't cut the mustard), I therefore expect it to work also on Chrome browser for Linux. Just to check if this was related to a debian bullseye package, I tested it on Ubuntu MATE too, which didn't do the trick. Haven't done any more testing than that on MATE.

This seems like a strictly firefox problem. -What to do?

Yours, Kaare

I'm having a problem sharing websites with others via, for instance, Signal. Telegram, WhatsApp or a social medium. There used to be a share button in the toolbar, but this I cannot find anymore. At some time there were also the three dots in the address bar that dropped down a menu for the page, which included a 'share' option. These dots seem to have vanished. Also I vaguely remember that the "share" function was also in he tab context menu once upon a time. However dropping down that menu does not reveal any "share" function presently. Then there was, if I remember correctly, the possibility to click the File menu at the top of the screen and then click on the Share menu item over there. But also there the "share" function seems to have vanished. I also looked in the settings menu, to find if there is a setting there which switches on or off the sharing function. I could not find such a setting. In short, it seems that I am horribly overlooking the "share" function. Please help me find it. Thanks. (Firefox 112 for Manjaro Linux)

Hi,

Is there any reason firefox would flag an mp4 file legitimately?

• The file extension and file type are absolutely mp4.
• There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

When I print to a PDF file, Firefox changes internal links (#go-there) to full external links (either https://the.website.tld/paper.html#go-there or file://home/me/paper.html#go-there).

This is obviously wrong, since the links are internal to the document.

How to I change this behavior?

Thanks.

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

Sometimes when a a browser add-on is having trouble, I removed it, then hit undo, and sometimes it works again after that adds it back on. I thought I'd do that today since some were showing blanks instead of their icons. I did one from the manager just fine, but when I removed one from the toolbar instead of the manager, no undo option was presented, and I don't recall which it was. How can I undo, or view recently removed extensions?

When I click ctrl+q by mistake, the browser window with all its tabs is closed immediately, with no warning. This has already made me lose data. is there a way to disable this keyboard shortcut?

For quite some time now I've had keyword.enabled set to false in my about:config because I don't like having the address bar try to autocomplete or turn things into search, when I do a ctrl-l.

I do like that I am still able to use ctrl-k to do a search when I need to. This would place a ? at the start of the field and whatever I type gets sent to search.

In a recent upgrade, ctrl-k still places the ? at the start of the address bar but doesn't send things to search. Instead, it now behaves as if I did a ctrl-l and typed in a bad URL.

I'm on Firefox 80 (on Fedora 32) but I can't be exactly sure which upgrade brought this change in behavior.

Is there a way to get the old behavior back? ctrl-l to enter a URL, ctrl-k to search.

I want to use a local html file as my new tab page. Currently there is no easy way to do this as far as I can tell.

Firefox at some point has removed the in-built option to set the new tab as a local file. Setting the home page as a local file is possible. But setting the new tab as either home (note, not 'Firefox Home') or explicitly the local file is not an option (see attached image).

Previous forum posts point toward New Tab Override extension. However, in recent releases, add-ons cannot offer a work around as Firefox no longer allows add-ons to access local files. In the image attached, New Tab Override extension shows that it cannot use a local file as the new tab. It can however take a file and store it somewhere it has control over. This means every time I edit the local file, I need to manually re-upload this to the extension in each instance of Firefox. It is no longer a good option.

I am sure I used this feature not too long ago and it feels like a very simple thing. I am sure I must have missed some setting or option. Any help achieving this would be greatly appreciated.

I just updated Firefox to version 81.0 in Linux, Windows and Mac, but the credit card autofill option is still missing from the Preferences menu.

I followed the instructions from here:

Hi! Does anybody know how to disable browser closing by ctrl+q shortcut? It is too close to ctrl+w and sometimes I close the whole browser instead of one tab. Moreover it is really useless and stupid feature since I have alt+f4. Why I need another shortcut which do the same stuff? And why developers ignore this issue which was reported on several forums? I tried install extension which disable it but it doesn't work for me.

in about:config page the options: browser.tabs.warnOnClose (true - default) browser.tabs.warnOnCloseOtherTabs (true - default) browser.sessionstore.warnOnQuit (false - default) browser.warnOnQuit true (true - default)

But when i do Ctrl+q accidentally, it closes the only Firefox window i have. This window has many tabs open. Yes it restore next time, but i want FF to ask me before closing it.

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

The question at the following URL has an answer that is no longer the best answer, but it is Archived and I cannot provide the better answer. Since "How can i reset 'container defaults' in FireFox Browser? I.E. I previously selected to open a certain 'site' is a specified 'container' - now I want to clear." is the top hit when I look for this on Google, I'm attempting to provide the answer here.

Dear Community,

I would like to download this extension: https://addons.mozilla.org/pl/firefox/addon/adblock-plus/ I would like to know how it works. If I will install this extension my firefox will be check hashsum for the files of this extension automatically? Or maybe public key of the organization/company who created Adblock Plus extension? How it is work? Can you tell me? I hope that people from Mozilla now read this and can answer for my question. This is very important for me.

Next question is to Adblock Plus extension. I can read this information: "This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing" so my question is why Mozilla don't recommended this extension? This extension now use 6,678,297 people so this is huge count. It is possible that this extension is not safe and these people now use malicious software? Why on dedicated website for this extension I can't see company name? Why this company is not verified by Mozilla? So my sugestion for people from Mozilla is to change this and check this extension or maybe add some information on website for this extension.

So I should install this extension? My friend use this on Google Chrome and he recommended me this software but I don't know if this is exatcly the same version. Maybe Chrome has verified Adblock Plus software and this is safe but Mozilla didn't verified this and this can be dangerous software because this can be not exactly the same version?

Next question is to adblocker. Why Mozilla can't make their own software to block all annoying ads and due to fight with malware? Example Opera browser have own buil-in adblocker. Why firefox can't do this? Maybe people from Mozilla should do this? This can be helpful because if this can be happen I will be not install any 3rd party software for firefox anymore and I will be safe. Maybe I can send somehow this suggestion to people from Firefox?

I hope that you can help me.

Yours faithfully, Peter
