Firefox 技術支援討論區

I'm on Windows 11 Pro 23H2. This is a pristine installation, downloaded from mozilla.org, default settings, no add-ons. - Firefox 126.0.1. - There are no cookies, history or cache to clean, since it's a fresh installation. - Connection settings is set default to "Use system proxy settings", although I've also tried setting it up to "No proxy", then restarting Firefox completely, then trying again with a new domain. No change. - DNS over HTTPS is set default to "Default protection". I've also set it to "Off", then restarting Firefox completely, then trying again with a new domain. No change.

I don't what else to try and I don't know what's wrong with Mozilla Firefox.

Can you help?

See video: https://x.com/jdvivar/status/1798859828393332982

Video in Firefox does not run .. no error messages .. nothing. It works fine in other browsers. When I click on the video .. nothing happens. It used to work but not now and I don't think I've changed anything.

Ive tried reinstalling firefox because i am not able to download anything with this browser. I thought freshly installing firefox would fix the issue and allow me to download but it didnt. I also am tried to download an addon/extension, and that automatically fails to download. How can i fix this?

A little while ago I noticed that the site I used to test my gamepads (hardwaretester.com/gamepad, formerly known as gamepad-tester.com) stopped working properly. I just assumed this was either something outside of the browser or the website itself was broken. Today I just tested with several other websites and browsers and confirmed that Firefox seems to be the issue. Even in Troubleshooting Mode it was completely broken.

L1, R1, R2, Triangle, Share, Options and the Left Stick seem to be the only things that function properly currently, with the DPad not doing anything and the rest of the face buttons/triggers hitting the wrong buttons. In the case of the right stick, L2 for some reason controls the vertical movement while the physical right stick still works horizontally. This controller works perfectly on the rest of my system, windows sees the proper buttons being pressed and games that support Dualsense work fine without any interference.

Below I have attached two images which show how the website I mentioned used to look, and the second image is how it looks now. I have a feeling some kind of update to Firefox's Gamepad API has broken this, somehow.

previously I added bookmarks to a menu bar at top of firefox. Now I have a bar that displays 2 bookmarks than a >>. I cannot expand this limited display or create a menu to display bookmarks though I can see them by clicking on the >>. Non of the menu suggestions is a fix.

Does anyone know how to control this and get me a more useful bookmarks menu display?

Hi. I am getting vertical lines sometimes. I have included two screen shots. I have checked browser.display.document_color_use = 0, and it was zero. I have tired this in Chrome and it works fine. And I tried in Firefox safe mode, and it still does these strange lines on some websites. I am running Windows 10, and have no other graphic issues except these lines. Websites are Windy.com and google maps. Thanks very much! James

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

During the past week, my open tabs will crash when I try to open them. All new tabs will crash. There are no crash reports. I cleared my cache but retained cookies. My temporary fix is to close and reopen Firefox. That works until I open another new tab.

A recent Firefox upgrade eliminated my toolbar "History" Icon. I want it back. Please do not suggest a three stroke keyboard alternative. Thank you.

Filled out a form on a Japanese Retail Store website to contact them and couldn't send the message. Message just hung up all day. I think the connection is secure (icon next to Firefox address bar does not have a slash thru it so I think connection is secure). That Firefox icon says it is blocking trackers and cookies on the website and "Enhanced Tracking Protection" is "On". And got message in bottom corner of website saying "ERROR for site owner: Invalid domain for site key". Using up-to-date Firefox browser, Windows 10 and Windows Defender Firewall. (Tried Windows Edge browser and it said connection was insecure so I followed steps to connect to it like changing Privacy settings and switching to a Private Window but it didn't help.) What else can I try to use this Japanese website? (Note: website does not have an email address listed anywhere.)

I had a set of Firefox bookmarks but when I signed into my Firefox on my Surface Pro 3, Firefox automatically imported my Chrome browser. I went back to the library to restore it and the old version was not there.

How do I get my Firefox bookmarks back. I tried to get them from my Android phone and it also has the wrong bookmarks.

Hi there, It won't accept my primary password even though I know it is the right one,it has always been fine and has never changed. I have entered it so many times now still the same.I don't want to go through the resetting and loose all my info, I couldn't anyway as it will not accept my primary password to be able to. Thanks Henry

For months, now, whenever I try to post a comment on a Yahoo! News article, it reads: "Your comment has failed to published." This only happens in Firefox. My "Privacy & Security" settings are set to "Standard," my "History" set to "use custom settings for history" with settings "Remember browsing and download history" and "Clear history when Firefox closes." so cookies and cache get cleared then.

Sometimes this works when starting a new session. But I shouldn't have to start another session and lose all of my logins just to post a comment on a Yahoo News article.

Anyone else having this problem? Is there an easy and permanent fix? What are you settings set at?

FireFox assumes that text size is the same for all pages in a domain, rferl.org for example. That is _not_ true. If I have set size to 50% and then take a link to a page that's different and have to set size to 67% to read it, when I return to the original page, size is 67% and text is too large.

Hi, I have used Firefox on my Android and laptop for a long time and now have an issue with my Android version on a Samsung S20. A fresh tab seems ok till I Google something, it then is very dark and does not display my usual 'All' appearance, it appears as what I would describe as adverts. I do not have any 3rd party Firefox plugins installed, its 100% pure Firefox. Can I restore to a previous point, can you help me please? The screen shot looks as if I have a dark mode of some sort but I dont.

Im running Ver 126.0.1 Build # 2016023311

Thanks

Recently I used the forgot about this site for reddit, but when I try to click on a link from either my bookmarks or from a web search I keep on getting. [The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.]

Not exactly sure what causes this or how to fix it.

I cannot copy anything from the Firefox browser. Copying works in every other application on my PC. Running Windows 11 Home and Firefox 126.0.1 (64 bit). I can copy things from other applications such as wordpad or Chrome and paste them into Firefox, but as I said, cannot copy anything from Firefox itself. Highlighting text in Firefox gives me the option to copy it, but when I do that and then try to paste it elsewhere, the paste option is grayed out. I have already tried a refresh of Firefox and a complete uninstall and reinstall. This issue has persisted for months, but today was the day I set aside time to fix it, and thus far I have failed. Please help me restore full functionality to Firefox!

I have F-Secure Internet Security installed. Browsing Protection by F-Secure says Security application not found, but it is installed. I've followed countless links, difficult to even find solution articles in either Firefox help or F-sure website. Inside F-secure settings a setup page takes me to the 'install add on' page, but it is installed! Allow automatic updates - on. Run in Private Windows - allowed. Run on sites with restrictions - allowed. Updates checked for. Permissions:

   Access your data for all web sites
   Exchange messages with programs other than Firefox
   Monitor extension usage and manage themes
   Access browser tabs
   Access browser activity during navigation

All ticked. Don't understand debugging tool.
