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.

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.

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

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.

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.

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.)

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?

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.

My windows got corrupted had to reinstall everything and this means i have lost my old Firefox account password is there anyway i can get all those saved passwords as i need them. Any help would be great

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.

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.

my computer broke about 2 months back and i am wondering if i can access the tabs from that device from another device since the original was synced (or i.e. is the a function in Firefox that lets me see all synced tabs from all connected devices)

going to the regular synced tab area there isn't anything from that computer there,

Firefox v.99.0

Hello,

I noticed that a setting on the about:config page was removed: the "security.csp.enable" setting. I was using this setting to disable CSP to be able to load local JS scripts on some non-locally hosted sites, for debugging and development, work related purposes.

Was this setting really removed? Is there a way to disable CSP on Firefox on the latest version?

Thanks! Gabriel.

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

When I right click Firefox in my taskbar I have a list of "recent" links show up. I have turned this off in about:config but they still show up. Any suggestions?

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'm downloading a lot of images, and every time I do so a popup box appears showing the most recent five downloads and a button to show all downloads, It covers some of the icons I use for downloading images which is frustrating. If I right click on any of the downloads one of the options is to Clear Preview Panel, so I assumed it was called Preview Panel, but help does not know about that and I can't find how to stop it coming up (it used not to until I did something, I don't know what) It's driving me crazy.

So for starters I am fully aware of the "When you open a link, image or media in a new tab, switch to it immediately" setting, it is turned off.

What I want to do is be able to open new tabs from my bookmarks bar without immediately switching to them. Regardless of middle mouse click or right click and open new tab. Considering the mentioned setting is turned off I would assume that would solve the problem but it hasn't. It has however made it so when I'm browsing or looking through search engine results it doesn't open a new tab right away. But when I have a home/new tab open and am opening tabs from my bookmarks bar, it unfortunately switches to the new tab immediately. I have had this working on a previous install but am stumped as how to replicate.

Any help appreciated, thank you!
