Firefox 技術支援討論區

Hi, I have been unable to open links from Emails accounts, both Outlook & Hotmail. I just get a message saying this. However if a am able to open them if have a pdf or a link to explore, which leads me to think this may be a Firefox problem. Thanksr

I have rather abruptly lost all audio in Firefox 77 on Windows 10. YouTube, Netflix, Amazon Prime Video, Facebook videos - all silent.

Meanwhile, I'm getting sound as usual when viewing those things in Chrome (and I would really prefer not to have to go back to Chrome), and all sound from other sources is working correctly - games, iTunes, Spotify, etc.

Does Firefox hook into my system's audio functions in some unique way, different from everything else? I've recently started experimenting with doing my own music and video recording/editing, and I've tried out a number of different audio/video apps in an attempt to find the tools that suit me, and I'm starting to wonder if one of the apps I tried modified or overwrote whatever system hook that Firefox was using.

Strangely enough, the audio spontaneously started working again yesterday, a few hours after it stopped, and was still working today until I rebooted my machine. Then it was gone again.

In firefox 77 I could choose different search engine for example duckduckgo as default search engine in private mode. In 78.0.1 this setting is missing, no way to search selected text privately or set different search engine for private mode. Only workaround is to go to about:config and enable "browser.search.separatePrivateDefault.ui.enabled". This fixes both problems. Is this still in beta and not officially available or are my settings wrong?

I want to find and display the location of a single bookmark in the entire bookmark folder. I can search my bookmarks using key words and display the bookmarks with the search terms. However, what I want to know is which bookmark folder the found bookmark is located in. Is there a way to identify that. Thanks.

I can't access my add-on anymore because you guys decided you wanted the look of my browser to change. They are all still installed, just now i can't change their settings or access their menus. how do i revert the graphical part of this update?

Similar to https://support.mozilla.org/en-US/questions/1173871. I accidentally clicked on remove this from address bar (thinking that would remove the bookmark).

I ran into https://support.mozilla.org/en-US/questions/1173871 with no solution but finally figured out how to add it back. But that thread was archived and closed. So I could not respond with a answer. Opening a new thread with to post the answer. Hoping that it will help others like myself who ran into this issue.

Evidently my spouse inadvertently checked a dialogue box, and now all files and urls contained in the e-mail will only download and not open in a new window. I have gone to Options-General and have checked "ask me" not download. Really could use help on this. Thanks Jon

There is a GM support forum that won't load images, they just show a blank area with a spinning circle. Works fine with Microsoft edge. I started Firefox in safe mode and still just get spinning circles instead of an image. The forum site is still usable, but have noticed same issue on other site, but don't remember the url.

This is the URL that doesn't work https://www.gm-trucks.com/forums/

On windows 10 pro 64 bit, Firefox 81.0.2

Windows 10 fails to include Firefox in the list of default browsers. Microsoft Edge, Edge Chromium and Look for an app in the Microsoft Store are the only options. Also Firefox is not included in the list of apps and features. (Latest Firefox 81 installed and latest Windows update installed.)

When I visit the weekly newspaper http://www.mambalamtimes.in/ the PDF opens in new tab without any issues with Google Chrome. However Firefox is trying get this PDF downloaded to the local disk instead of opening in the new tab.

I guess Firefox also has an inbuilt PDF reader so not sure why it is preferring the file to be downloaded over displaying and rendering the same inline...

When I have multiple pages open and navigate off the page and work on something else using another program, When I hove over the Firefox icon in my Windows 10 taskbar it shows multiple pages in the fly out menu. What I'd rather have is simply a return to all the full screen tabs. The issue is intermittent, due to my newness to Firefox. Is there some way to change this?

The "Help Articles" don't tell how to turn on the media playback control feature. They contain no information on how to do it.

I used to be that if you clicked a link and "Opened in a New Tab" that this child tab would appear to the right of all existing tabs.

In the later versions of FF, these child tabs are inserted directly after the parent tab that created them.

This may make logic sense to some people but, maybe because I'm dyslexic, position is critical and all my existing tabs beyond this child have just been moved up one place, which I find very confusing.

I often Open a New Tab for temporary tangents, so I don't lose my place in an existing page, but this means that my primary tabs are tromboning right and left as I open/close.

Is there a parameter that I can change in Config to set the behaviour back to adding new tabs to the end of the list?

Page loading in Firefox 82.0 is way too slow, including on your own site, mozilla.org. It was even worse till I got Norton Security Suite to fix their problem, but it is still way too slow. Please fix asap.
