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.

Before the recent 1-2 updates, pdfs,pictures and .torrent meta files used to get saved in temp folder which I LOVED very much. Recently these are getting save in my download folder instead of saving in the temp folder.

I changed this setting to allows ask. Still the files are getting saved in the download folder after opening.

Please assist me to resolve this issue. Thanks.

See images. The buttons on video players don't look like play, pause, gear, etc. They look like gamepad buttons. But a gamepad is not connected to my PC and I haven't connected one in months. I have tested it with videos on invidious.snopyta.org and tagesschau.de.

I forgot my password to my Firefox account, and only just realized I haven't updated it in KeypassXC when I was trying to log in to a new machine. It seems that, even though I am already logged in on my old computer and have full access to my account (including saved passwords, bookmarks, and browsing history) I can't find a way to reset my password without deleting all of my synced data. From the "Change Password" menu, it requires my old password if I want to change it without deleting everything. Also, I have 2FA enabled, so why isn't there the option to authenticate my identity in a password reset using 2FA instead of my old password? I know a similar thing already exists for recovery keys, but I only have 2FA. Is there any way for me to reset my password where I don't lose everything? Thank you.

Some how Yahoo jumped in and displayed a yahoo Home page with no way of deleting it. I tried installing Firfox..But it became stuck half way..what should I do to get back to Firefox ?

HP laptop isn't recognizing the wireless printer. I go through all the steps but when the screen usually shows the printer name and info. it fails to do this. Can't get any farther than this.

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.

New computer, running Windows 11, McAfee LiveSafe came with for 30 day trial. I use Firefox, have since 1997. Just added Mozilla VPN. Old computer ran Xubuntu. Windows 11 needs antivirus because it's Windows. So. How compatible are McAfee LiveSafe and Firefox with Mozilla VPN? What suggestion, if any, does Mozilla have for an antivirus program that will work well for Windows 11 but not mess with Firefox and Mozilla VPN? Thank you.

I am using a Mac and have no idea what this is or how to turn it off, image attached it comes up down the bottom of the taskbar even when firefox is not running. Thanks

When using firefox web browser to visit investors.com, I receive the attached image as the web page. I've been using this website on this browser for months and never had an issue until today.

This is the first time, that an update lost all of my tabs. Is there a way to access previous sessions, other than the most recent one? I would like to access a session from last week, and see if I can get my tabs back. I'm very unhappy about this and I've not been able to restore my tabs. The current tabs are place holders, and they do the reflect what I had before the update.

In the past, when ICS files were in a mail, I had been asked what to do, and could open them in OUTLOOK. This option has been apparently cancelled and it only asks where to save the file, without any option to open it directly. Furthermore, when I try to modify it in the "settings" and change it to "Always ask" I can't find no ICS files nor OUTLOOK SCHEDULE files. Please advice. Thanks

Firefox no longer supports Norton Identity Safe Mobile Unlock and Auto Fill UN/PW, anyone have a solution? I have Windows 10 with Norton Extensions enabled and Norton Vault is displayed but does nothing. Firefox is up to date also (that could be the problem; everything worked a week ago.)

There is a site I can access with Safari from my iPhone but not with FireFox or Edge from my Windows laptop. Specifically, the site is www.thechildrensmediaconference.com. I have tried the advice in a previous thread on this theme with no success

My Grandson loaded some type of coupon app and every time I log into some type of store etc. I get this coupon discount, he said it was on Mozilla Firefox. I want to delete it but I can't find it, can you help?

Every time I enter a link to a google service, I see a notice that says "Your should be redirected in a moment..." and then I get redirected to the Stanford University website (https://pass.stanford.edu/signin.html). It is not a specific website redirecting me, but rather some algorithm is detecting a google link and sending me to Stanford University instead . For instance, if I paste in a link to a particular location in Google Maps, I will end up at Stanford instead. I have no idea how to fix this, but it makes me avoid Firefox and use Chrome because Chrome does not redirect. I would rather use Firefox.

I have a user who runs SRS/Crystal Reports on their Windows 11 Lenovo laptop, but every time we go to the website where a Java-enabled pop-up window for viewing spreadsheets is supposed to load we keep getting a "A plugin is required to play this content" error message, but no option to install/approve the running of Javascript.

I have downloaded and installed the JRE and JDK on the endpoint device, but still no luck getting Firefox to load it. I am running the 32-bit version of the web browser, not 64-bit, so I am kind of stumped about how to proceed from here.

Is there a place I can manually download/install these Java plug-ins?

Thanks.
