Firefox 技術支援討論區

I am suddenly unable to access websites, some of which I've viewed for years, like Facebook and my email, for Pete's sake. What is going on? I'm told there's a security risk and there's nothing I can do. What has changed. This is distressing in the extreme. I have put virus protection in place, and use a VPN, so I feel reasonably secure in my online work. Something has changed at Firefox, what the heck is it, and how do I correct it?

I'd like to ask a question. Is this the Mozilla money transfer address: support_moz ? Thank you! Alex Fisher, Mozilla, Windows10; Vienna , Austria. [email removed from public]

Besides old content from 2017 where is the most current listing of Tabs below the URL and below the Multi Bookmarks lines. I have the code inserted in the CSS code after the code for the Multi bookmarks section. So, why is the Tabs showing up at the bottom of the screen. Can someone point me to the right version of tabs? I'm on 105.0.2 10-8-22

We have our downloads set to a network location, and ask to save in location. We have needed to apply the fix I found in a forum by going to about:config, browser.download.improvements_to_download_panel and change value from true to false.

However, when even going to a PDF on the internet, it is automatically saving to the network location. Can this be changed?

Thank you! Nicole

Dropdown lists are not displaying their contents when selected on certain websites, including eBay.

I have tried using Troubleshoot Mode and the dropdowns are still not displaying.

Here's an example where I am seeing this behaviour: https://www.ebay.co.uk/itm/255536264049?var=555488018135

When I select the Resistance Level dropdown, nothing happens. It's the same for any listing that has a dropdown.

This issue occurs in both RPM and Flatpak instances of Firefox.

I have tried the same page in Chromium browser on the same computer and the dropdown functions correctly in that browser.

I have also noted the same behaviour on other websites, such as train booking sites, but I don't have any other examples to share at the moment. It isn't an isolated eBay issue anyway.

Any ideas? Is anyone else experiencing this issue?

Hi Firefox community,

Do we have any settings in firefox where we can enable/disable dark mode in firefox browser instead of installing a plugin or addon? I am looking something that is offered within the browser instead of a plugin.

Thank you all.

Auto-updated to v105 today (105.0.2 64-bit Windows 10) and all bookmarks were gone. Not just gone but the bookmark manager seems not to be rendering properly (see attached image where there should be at least some elements drawn). Additionally, neither the bookmarks nor history left pane show anything (second attachment).

The 105 update was applied this morning when first opening the browser. Profile folder -> bookmarkbackups shows a backup from just before the update. Bookmark library -> Restore gives that backup as an option, but restoring that backup has no effect (does nothing).

Exiting Firefox and manually moving places.sqlite to a backup location and then restarting also has no effect. places.sqlite is rebuilt but library -> restore still has no effect.

I've read the forums, i've tried adjustments for days on Win 11 and firefox. Zoomed in zoomed out, adjust font sizes Either it's way too tiny to read or the page is fine but text over laps i've tried the zoom in on text only as well Basically tried everything. enclosing a youtube page for reference

Hello, I use Firefox 105 on my PC. I have embedded various YouTube videos on my website. I've had the following problem for a few days: I can see my videos on both my smartphone and tablet without going to YouTube. On my PC (Win 10 Pro Vers. 21H2) the display wheel "rolls" without opening the video (... "an error has occurred, try again later"). But if I click on: "Watch on YouTube" plays the video via YouTube correctly. Does anyone have any idea what might be causing this? Is there a wrong setting in the Firefox browser? Many thanks and best regards Helmut

Every time I open a link in firefox that is a youtube short, it opens up an entirely different short than I selected unless I am using a "full video" version of the link. I have tested this and it works fine if I copy-paste it into chrome.

Recently, https://www.nhlottery.com had experienced a hostile act & then shut down their site. They were super great at being transparent, etc. However, as of today, staff have reported it is up and running with no risk.

I have an account that I am unable to access due to browsers reporting security issues. I don't know what to do? Im sooooooo not a techie, but I can follow directions. Help! ST

I can't use my mic on the web version of Discord. It never asks me to enable or disable mic settings to allow the mic to work. Other tips to get the mic working have not helped.

I just made the switch from Chrome to Firefox, and I'm still trying to understand the small differences that exist between the 2 browsers.

While on Twitter, what I usually do is middle-click with my mouse on a Tweet to a new tab that I want to look into later, then continue scrolling down my timeline, then check out the Tweets I opened in the new tab(s). However, when I try to do the same thing on Firefox, it automatically opens the new tab. Because of how Twitter works, this also reloads the Home page when I opened it up, so I just lose anything I was just looking at when I opened the Tweet in a new tab.

What can I do differently here?

on a MAC LAPTOP....Mozilla Browser updated yesterday... missing all logins/passwords...sync is on... how can I retrieve the old mozilla for logins?

HELP PLEASE..!!!

I installed the new Windows 11 update now when I exit out of firefox "X" the next time I go to open and error tells me that firefox is running (it's not showing open and running) and I have to close.

I recently updated to windows 11 and now when I open firefox my tabs are no longer there. I have repeatedly gone into settings and checked "open previous windows and tabs". Dosnt work. Still opens to a blank browser with only one 'new tab' present. Most troublesome since having my tabs for my email addresses, calender and google keep come up each time is a big time saver for me. Ive been doing this for years and thanked mozilla silently many times for this. But now Whats Up???

Hope someone can help. I see it was posted last year but none of the response makes sense/applies to me.
