Firefox 技術支援討論區

The search boxes in the inspector window window returns no results whenever I try to search for specific key-value pairs like: role="main".

I can only get results for main or role. Is there a search string parameter/syntax reference anywhere? I've searched high and low, but articles/references found in the documentation is VERY basic.

Thanks

Hello team firefox!

I'm building my own webpage, where some videos are played (with scenes, so there will be a back and next button). When i embeed a video with the controlls, everything works. But: as soon as i turn on fullscreenmode (which the videos are played in normally), my two next and back buttons dissapeer (behind the video ofc).

So my questions to you: could you please send me your video control html, css and js? Would be reaaaly cool of you!

I would like to open firefox through selenium and upon file download, the file to be stored on another path other than the default, the downloads folder, automatically, without getting the prompt dialog.

This is can be done through configuring a new profile but I can't find any implementation example on the web.

Thank you in advance

Does clicking a .js file in Network disk cache (about:cache) execute the script? I clicked a .js file that opened an information screen with the word key followed by the URL for the .js. I clicked the .js URL and a Firefox screen with text opened.

Is it possible to run a perl script on my pc from a button on the firefox toolbar. I would also like to grab the current url i'm viewing - is there an easy way to do this.

Hi, I'm using webpack 4.6 and Babel 7+ to compiled JS, CSS, and their sourcemaps. I can edit individual SCSS files directly in the style editor, and have verified that webpack watch triggers a compilation, so a new css file replaces the original.

I was expecting Firefox to render style changes without me having to manually reload the page (as I have been able to do in the past with tools such as grunt). But that's not the case. Styles are not automatically updated and I have to reload the page by hand. Not a big deal when it is only once change I have to do, but on my work, I have to do this dozens and dozens of times when I'm developing, so it gets a little tiring.

Any suggestions on how to trigger the 'live' updating of styles ?

Thank you!

Guys, Removing Event listener on chrome is simple, just view it on the bottom right section, expand the element on the event trees, then click the 'remove' button. Tada and putta, the event is no longer functional. But, on firefox platform, how to achieve that???

Hello. I'm using a brand-new installation of Firefox 78.0.1 on a freshly installed copy of Windows 10 Pro. The only way I can get Firefox to display any notifications is by having alerts.useSystemBackend set to true. While this is set to false, notifications will not work. If I use this site to test them, it just says, 'queued for display', followed immediately by 'closed'. I've also tried creating a new profile and testing it again with no success. All sites were granted notification permissions in each case.

Thanks for any help.

As mentioned here https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/frame-ancestors, CSP: frame-ancestors is supported from Firefox 33. However, it seems doesn't work.

I am trying to embed a 3-party site into our page using an iframe. The 3-party site did whitelist us using these headers - Content-Security-Policy: frame-ancestors 'self' https://*.ourdomain.com - X-Frame-Options: SAMEORIGIN

It works fine on Chrome, but not Firefox. I am using Firefox 79.

Is there anything wrong with our headers?

Thank you!

In my web app I had a customized scrollbar. In the most recent update of fire fox it duplicates my scrollbar so I have my own customized scrollbar and next to that there is fire fox's default one. They are entirely synced and scroll together. And I do not wish to hide m own scrollbars for certain reasons. Can anyone help?

We have an application that was integrated with several other legacy applications in the organization. We started upgrading our application to HTML 5 standards to make it work with all modern browsers such as Firefox, Chrome and Edge. Now the problem is that, our application has redirect links to 3 to 5 legacy applications that were coded for IE 7 and no where in the migration path. When the users click on these links while working on our application, Firefox opens a blank page, making them as blockers for our application uplift. 1) is there a way to force a link to open in IE while the parent page is launched using Firefox ? I have seen this link : https://stackoverflow.com/questions/43615678/force-a-link-in-i-e-to-open-in-firefox , but this is for the opposite requirement...open Firefox from IE. 2) how do you run applications requiring .cab files on Firefox ? if there is an answer for this, we don't need to worry about #1.

Thanks.

I have a page using javascript to filter div's depending on a selection criteria. On Safari and Chrome, the filtering works just fine. Bit onFirefox (the latest version) instead of seeing the filtered list I see a new tab, titled About:

The attached images show the sequence, screen1 and then screen2 then screen3. I should see screen1 with a subset of the divs in the scrolling section.

The javascript is:

  function TLSshowhide(tlsclassname) {
/* first, hide all responsive div's */
var y = window.frames['theinterviewsdataframe'];
var z = y.document.getElementById('theinterviewsdata');
var x = z.getElementsByClassName('responsive');
            var i;
            for (i = 0; i < x.length; i++) {
                    x[i].style.display = 'none';
             }
/* then, show the responsive div's with the selected classname */
           x = z.getElementsByClassName(tlsclassname);          
           for (i = 0; i < x.length; i++) {
                    x[i].style.display = 'initial';
            }
}
/* When the user clicks on the artist button,  show all responsive div's */
function showArtist() {
/* when showing the artists, show all responsive div's */
var y = window.frames['theinterviewsdataframe'];
var z = y.document.getElementById('theinterviewsdata');
var x = z.getElementsByClassName('responsive');
            var i;
            for (i = 0; i < x.length; i++) {
                    x[i].style.display = 'initial';
             }
}

You can see this in action for yourself by going to http://cultconv.com/CultConv20181030/theinterviews.html and clicking the By Artist button

The list of DIV's being displayed is found in http://cultconv.com/CultConv20181030/theinterviewsdata.html

All help appreciated.

I need to know when Firefox last updated itself. The about page has: Version 63.0, first offered to Release channel users on October 23, 2018. I am testing using geckodriver.exe & everything has suddenly stopped working. Last worked 29/10/2018 at 17:00.

Please see the attached image.

The icon on the dev tools is missing, especially on the "debugger" tab.

Application Basics

Name: Firefox Version: 65.0a1 Build ID: 20181102100039 Update Channel: nightly User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:65.0) Gecko/20100101 Firefox/65.0 OS: Linux 4.18.16-300.fc29.x86_64 Multiprocess Windows: 1/1 (Enabled by default) Web Content Processes: 10/8 Enterprise Policies: Inactive Google Key: Found Mozilla Location Service Key: Found Safe Mode: false

Whilst debugging an Angular 5 app, I have noticed that when I attempt to step on from a breakpoint with the righthand-side panels collapsed, the debugger refuses to continue processing the code.

Opening the rhs panels and attempting to step on (continue) works as expected.

This appears to be a bug in the debugger.

I am debugging an Angular 5 app in Firefox DE, but the page load is very slow when debugging.

I have blackboxed a number of scripts, e.g. common.chunk.js, polyfils.bundle.js and more besides, but still slow.

I notice that the sources panel, after the delay, updates to include "Angular", so I am assuming that the delay is likely there. I have expendanded that folder and it naturally contains a great many files.

Is there a way of blackboxing these too, without individually selecting them? Or are there other tips for speeding up/skipping files when debugging an Angular application?

Thanks, Victor

Hello community, <select> styles not working anymore in firefox, the browser shows only the default 'style'. In Chrome the personal styles are visible. The issue was labled 'Bug 910022' in 2016, since then no changes. Best regards

I get "Skip to Content" at the top of the web site.

Website is https://simplexmerchantservices.com It's built using latest WP and Elementor Pro Using Cloudflare CDN It does not work for me or any of my employees in Firefox. I tried FF Safe Mode - no change. FF ver 73.0 64-bit

Cache/Data cleared New FF install

We have a simple HTML home page that has links to the sites we most visit. This is the default page that comes up when we start FF. For instance, the web site for CNBC financial news is coded in HTML like this:

All the web links are in lists in cells a multi-cell table. There are about 40 of these links in the home page.

While debugging a network problem recently using wireshark, I noticed that when I opened this home page in FF, There was a storm of DNS queries for all of the web sites in the home page! None of the web links were clicked on, this happens when FF starts up and just displays the home page. The same thing is happening on Windows 7 and Linux.

I consider this invasive and would like this activity to stop.

Why is this happening? Does this "feature" have a name? How do I stop this from happening?

Thanks, Ed
