Firefox 技術支援討論區

Hello!

I get this error often when I try to access various websites. This doesn't happen when I use Opera, so I assume the problem is not with the websites.

My OS: Windows 10. My Firefox version: 127.0 (64-bit).

Hi everyone,

I'm experiencing an issue with my website's compatibility with Firefox. website My website, which provides online educational resources and tools, is not displaying certain interactive elements correctly when accessed through Firefox. These elements work perfectly in other browsers like Chrome and Safari.

Specifically, I've noticed that some JavaScript-based interactive features, like quizzes and drag-and-drop activities, either don't load or don't function as expected. I've already cleared the cache and ensured that Firefox is updated to the latest version, but the problem persists.

Has anyone else encountered similar issues, or does anyone have suggestions on how to troubleshoot and resolve this compatibility problem? Any insights would be greatly appreciated!

Thank you, fatemahx

Nightly updated this morning and the help menu from the sandwich has stopped working. The menu options display, but none of them function. Mouse click makes the menu disappear as if it's going to show the panel attached to the option.

Version: 129.0a1 Build: 20240613093628

I like Firefox and am using it for years, but I cannot accept lengthy loading time. I have a fast and stable internet so this is not the problem. Please let me know what the problem is and how to fix it.

I've been trying to install an add-on that is in the .zip format. I set xpinstall.signatures.required to false and restarted the browser, yet Firefox keeps telling me the add-on cannot be installed because it's not verified. Is there a way to change this?

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

I have been trying to contact support about an issue regarding being able to change my account password to the page at https://support.mozilla.org/en-US/questions/new/mozilla-account/form, however I cannot seem to submit any information. When I try, the page reloads, followed by multiple uncaught errors observed in the console, including a cross site origin request block error (in the latest stable Firefox). My browser settings use the standard browser privacy setting, and custom DNS.

Regarding the error I was trying to report, I am unable to change my password, receiving "incorrect password" despite entering the correct current password. In the browser console, a POST response with error 400 is shown.

Hi. I feel like this problem has only shown up in the last couple months but for some reason, on firefox, when say watching something on youtube and I go to pause or skip around in the video I'll get this very unpleasant distorted digital noise sound very briefly. I've tried turning off and back on hardware acceleration and some other things but no dice. I can hear the distortion on my onboard sound, my usb headset, and hdmi audio through the graphics card so I don't think its my hardware. This distortion also doesn't happen with say MPC/VLC or watching Youtube via Edge or Chrome.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

I can open an email or a google search for this particular website, Sundance, click on an item which then opens on my screen but Firefox is unresponsive when I click within this item screen for details like available sizes and colors. This is the only site that this has occurred.

I was wondering about password recovery, or account continuity when changing a password.

I have a new machine at work and want to add my firefox account....

Today all of the sudden, one of my computers running Firefox won't connect to Youtube at all. It says security issue with HSTS. It also says there there is nothing I can do to resolve it. Surely that can't be true. Youtube runs on every other computer in the office just fine.

Here is a screen capture of the message:

Apologies if I'm repeating a previous request - couldn't tell if it was submitted.

I'm running Windows 10. While changing the startup screen somehow an image I thought was deleted appeared and now is frozen, apparently on top of a Firefox window. I've rebooted, restarted and followed the Windows help suggestions with no success. Right now I don't know whether this is a Firefox or Windows problem. I updated Firefox today to the newest version before this happened.

Any help will be appreciated. I can open new Firefox windows.

P.B.

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

Hi,

Just the other day I started getting these popups from "anti virus service" that keeps popping up on my screen. I do not nor never did have McAfee on my system. I did a deep search, and there is no program on my computer, nor in my startups, nor in my popups allowed relating to this. It is only a problem with Firefox. Any solutions?

Thank you, John

Firefox version is: 127.0 (64-bit)

My problem is that Firefox seems to be ignoring "#:~:text=highlight this".

Maybe there's something under about:config? I can't find it.

Thanks

Can you suggest any functions or apps that I must or should avoid? It's important that I NOT use a VPN, and that I use 'open-source' in a probably 'shared access' situation. GRM PL

Back in October 2022, changes were made to how private windows appear, separating their icon in the OS taskbar, giving it a new icon, and putting a badge on the top right of the window.

At the time, support threads (such as this one https://support.mozilla.org/en-US/questions/1393494#answer-1542568 ) suggested changing three options to revert these changes: -browser.privateWindowSeparation.enabled -browser.privatebrowsing.enable-new-indicator -browser.privatebrowsing.enable-new-logo I really dislike how these changes look, and so immediately followed this advice. In my advanced options, every one of these is still set to "false" to this day. However, after a recent Firefox update (my current version is listed as 127.0), these no longer seem to have any effect making the new look the only option.

I would strongly prefer to at least re-combine the taskbar icons for standard and private browsing into a single icon. Is there any way to do this in the current update, or is this change permanent going forward? If it is permanent, would reverting to version 126.01 risk losing my current Firefox profile?
