Firefox 技術支援討論區

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

Hello

We have lost our developer access to manage an extension. Nobody knows which email address and account was used to manage the extension.

What is the procedure to get ownership of the extension ?

Thanks Frédéric Jahard

Receiving the following message when trying to log onto well know and compliant crypto website:

403 ERROR The request could not be satisfied. Request blocked. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error. Try again later, or contact the app or website owner. If you provide content to customers through CloudFront, you can find steps to troubleshoot and help prevent this error by reviewing the CloudFront documentation.

Never had this problem in recent past, only after updating Firefox to 93 (64-bit) Linux Ubuntu 20.4. I DON'T USE CLOUDFRONT. So what else may be the issue? Thank you.

Hello! Just installed Ubuntu 20.04.4 on my laptop and now find that I'm not able to watch some YouTube videos on Firefox 97. It seems mainly just live streams that I can't watch. When I go to one it shows "Your browser can't play this video...Learn more" in the video window. Clicking Learn More takes me to a page that doesn't explain what the problem is. Any idea what the fix might be? The same videos play just fine on other devices on my network. Any help would be greatly appreciated.

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

i've tried everything, safe/troubleshoot mode, manually uninstalling and even refreshing firefox in normal or safe mode, the extension has the "Can't be removed" button the profile directory (/home/xxx/.mozilla/firefox/v6kxe18l.default-release-1648663005215/ for me) don't have a extension folder after refreshing firefox, when booting up i immediately get the extension reinstalled

This is clearely skooky behavior in my opinion and I really don't want this extension

I have a linux debian 11 o/s with up-to-date Firefox I don’t know which version at the moment it is whatever debian repo pushes down. I have 5 profiles on this particular computer with no previous issues. I decided to create another profile to be used for some test work and when I created it I then launched it and opened a few tabs to make sure it worked then closed. I planned on copying the profile files from another profile into this one so I went to the profile folder - /home/user/.mozilla/firefox/profile.names

Once there I saw my other profiles but could not locate this one so I went back to an open browser where I had the about:profiles page open and decided to delete that new profile and start over I figured maybe I accidentally saved it to a different directory. I hit remove it and it gave me the box asking if I wanted to remove files I chose yes I then go back to - /home/user/.mozilla/firefox but folder firefox was gone with all of my profiles all that was left in .mozilla was - /home/user/.mozilla/extensions and - /home/user/.mozilla/systemextensionsdev. Both of these folders - “extensions” as well as “systemextensionsdev” are empty. I go to the local directory for each profile and the data is still there for each of the profiles - /home/user/.cache/mozilla/firefox/profile.name.

The recycle bin is empty. A system-wide search for the profiles comes up with just the ones in the .cache folder. Back at the about:profiles page any attempt to open the preexisting profile results in a prompt asking me to create a new profile. I still have the one profile open and the addons are not working correctly. I did a bookmark export on this profile and doing so generated the “firefox” folder that had disappeared plus a profile folder using the same name of this open profile - /home/user/.mozilla/firefox'profile.name - it created a profile folder for this open profile using the correct name.

Any ideas on how this happened? Can the local profiles still in .cache be used to somehow restore the full profiles?

When clicking on a link that does not include "www." in the URL, I am presented with an error SSL_ERROR_BAD_CERT_DOMAIN. But the certificate is good. the problem was the URL that did not include the "www."

This would be an easy fix! Just add "www." to the URL if it is missing. It could eliminate user confusion if they do not understand.

Just a suggestion

Since the last Firefox upgrade I have lost the ablity to connect to my Iomega Home Media Hard Drive, the NAS unit. What can be done to remedy "Unable to connect An error occurred during a connection to 192.168.1.201"?

I need to automate the deployment of Firefox along with the extensions. I put three extensions (uBlock, Translate Web Pages, and Auto Tab Discard) in the /usr/share/mozilla/extensions/{ec8030f7-c20a-464f-9b0e-13a3a9e97384}/. All extensions load normally, except Auto Tab Discard. When running firefox with the -jsconsole option, I see what the screenshot shows (the message "Invalid addon ID"). But the installation to user profile is successful. I add the extension ID to manifest.json, and get the following output in the console: addons.xpi-utils WARN addMetadata: Add-on {c2c003ee-bd69-42a2-b0e9-6f34222cb046} is invalid: Error: File /usr/share/mozilla/extensions/{ec8030f7-c20a-464f-9b0e-13a3a9e97384}/{c2c003ee-bd69-42a2-b0e9-6f34222cb046} does not contain a valid manifest(resource://gre/modules/addons/XPIInstall.jsm:669:11) What can go wrong?

System: Debian 11 (bullseye) Firefox version: 91.4.1esr (amd64)

If you need any other information, please ask, I will write it down.

Firefox unter ubuntu 22 hat keinen Zugriff auf die lokalen Dateien (z.B. /usr/share) Der 'open' auf '/usr' scheitert mit 'read'-Zugriffsrecht.

Ganz egal, was in '/etc/apparmor.d/usr.bin.firefox' respektive in '/etc/apparmor.d/local/usr.bin.firefox' spezifiziert wird, das Zugriffsrecht für '/usr' ist immer 'read'.

Wie kann man auf die Dateien unter '/usr/share' zugreifen?

Mit freundlichen Grüßen

Arch Linux/Firefox Nightly 99:

the user agent has a difference of 8 versions with the current version of the browser. Two browsers on the computer - exactly the same in regular Firefox 97.

Machine information: OS: Manjaro Linux x86_64 Host: 80TG Lenovo V110-15IAP Kernel: 5.19.1-3-MANJARO DE: Plasma 5.24.6 Xorg WM: KWin CPU: Intel Celeron N3350 (2) @ 2.400GHz GPU: Intel HD Graphics 500 Firefox: 103.0.2 (x64)

Problem: Scrolling in firefox is feeling weird: instead of smooth scrolling with 2 fingers (like on smartphone with 1 finger) firefox scrolls only by steps only when I move my fingers enough to trigger scrolling. In other applications I can scroll smoothly and fully control scrolling, I can scroll exactly N pixels if I want. In firefox I can only move by N pixels per M cm fingers movement on touch pad.

It's feeling as indirect input. I can feel same feeling on Windows with simple mouse. Firefox scrolls slower than Opera.

How to reproduce and find difference with other applications:

1. Download Firefox and another application with direct input (Opera or Telegram for example)
2. Scroll Firefox
3. Scroll another application

On Linux Ubuntu 18.04, on my laptop, I have 2 versions of Firefox. Version 85.0.2 which I've been using for a while, and version 97.0.1 which I have just installed. I want to sync the new firefox version with all my data and choices that are on the older version of firefox. I think I am being told to sync my older firefox settings with firefox on my phone. I do not have a phone. I only have 1 laptop. I need help, I don't know how to accomplish syncing with 2 different firefoxes on the same laptop.

Firefox currently has a URL color formatting scheme which greys-out all parts of the URL in the address bar except for the top-level domain and the 2nd-level domain (with some exceptions).

I am building a website where my organization-specific domain is NOT located on the 2nd-level domain, but rather on the 3rd-level domain.

I plan to use the domain "obb.ll.land". The "ll.land" part is basically a domain that the Liberland Government operates and from which it sells 3rd-level domains to members of the public. Think of "ll.land" as a temporary ccTLD for Liberland. (ICANN requires countries to be on the ISO-3166 list—which Liberland is not yet on—in order to register an official Internet ccTLD.) Therefore, any domain that is formatted as "[SUBDOMAIN].ll.land" should be presumed to be the foundational domain for a given organization that uses it.

Therefore, when a client sees a Liberlandic website, the domain should have the 3rd-level domain included in the black-text portion of Firefox's URL color formatting scheme. Otherwise the scheme would be misleading about the true nature of the website involved. For example, the 3rd-level domain of "https://www.floating.ll.land/" should be included in the black-text portion. Same with the 3rd-level domain of "https://register.ll.land/". However, as of this writing, no ".ll.land" site has the appropriate URL coloration to my knowledge.

How can I solve this problem? Is there something which developers like me should add to our websites individually, or will Mozilla be responsible for handling this matter?

Thank you all in advance! :)

I saw where this was a problem with Netflix, Amazon Video and other sites with Fire Fox and that one person even used professional version and still had the same problem.

What I cannot see is where he got the video codex that allow Netflix to work on Fire Fox version 88, let alone this newest version that Mozilla has created.

My old Linux computer died and I have removed the still good SSD from it. I have installed the latest Firefox on my new computer and would like to restore the bookmarks and other saved data to the new computer.

I am running Ubuntu 20.04, the old computer was on Ubuntu 18.04.

Can these things be restored, and if so what do I need to do?
