Firefox 技術支援討論區

Hello,

I am learning to look at websites with help of the development tools and the inspector tab and I am trying to get into how the web works and how the different programming languages interact and so forth. When moving the mouse over parts of the website, the relating code is highlighted in the inspector tab. I am having an issue as follows:

The first image shows a part of the website code. The mouse cursor is on no specific position, I marked its position with a blue arrow.

In the second image the mouse is over the red "free options" button and in the inspector tab a div appears out of nowhere. It does not appear in the code unless the mouse is moved over the button and disappears as soon as the mouse leaves the button. I have never seen that before (maybe because I am a beginner) and have no clue what happens there.

Is that done with javascript? Or with php? Or with css? Or anything else? What happens there and how can the actual code change?

In the inventor tab, does the code have to do with the DOM rather then the sourcecode of the website is that right?

Please give me some light =)

regards p3ppi

I am using a Mac and have no idea what this is or how to turn it off, image attached it comes up down the bottom of the taskbar even when firefox is not running. Thanks

For some reason, when I try to autofill with stored credit card information, Firefox (99.0.1) fills the form with credit card number and expiration date when I mouse over a credit card choice, and then when I actually make the choice, the entry gets erased.

I have checked, per an earlier (now archived) question, and there is no "autocomplete off" (or any mention of "autocomplete") in the web page in question.

In KDE 5.24.4, Linux. I started to have some issues with "Open containing folder" probably because I installed many Gnome apps which may cause bad configurations in my system.

I suspect this cause this issue even though I don't really have gnome file manager:

https://polywogsys.livejournal.com/309405.html "Gnome based file managers, Nemo/Caja/Nautilus provide the entry org.freedesktop.FileManager1. So it doesn't matter what you set as your default application for the filemanager mimetype - as per the freedesktop.org standard, firefox will always select a filemanager based on dbus (if it's there)"

But because the mimetype points to "dolphin", I dont really have other explanation either: $ xdg-mime query default inode/directory org.kde.dolphin.desktop

Firefox was selected FOR ME by a third-party site that uses it for webinars (I think WebinarJam was the culprit; now they're using Zoom), as my default browser - I did not select it, now I can't unselect it. I've been using Chrome for everything, now Firfox is hijacking every link I embed in any Word doc - this should NOT have happened. Please tell me how to UNselect Firefox as my default brower, which I never selected to begin with!!! Thank you, Scott (Skip)

From what I understand firefox now supports subtitles in picture in picture mode but when I use it for youtube it doesn't work. I have enabled the captions in the advanced settings and I have tried it with all my addons disabled.

You actually have an egregious error in your install procedure/program. 1) you fail to tell folks/warn them close down i) FF when installing the update and/or ii) save and delete all open sites in the FF being upgraded. 2) there is a failure to TELL us reboot FF after the install.

Doing research and writing all day long as I do, I actually hold a number of reference sites open in FF as I work.

My friend who happens to understand all this computer stuff tells me that the open sites on my FF is what impeded the successful install . . . .

The other grumble I have with you-all is that it has taken me too much time to try and find a way to respond to you with the information needed to solve this problem for the FF community . . . .

I am a paying/donator to FF . . . and I must tell you I am beyond disappointed by all this dropped ball on sensible communications practice!

With the help of community archives I got Form Autofill working again, but it only partially fills out the forms. It always leaves out the City, State and Zip code, and although they do not show up in Saved Addresses they do appear in the Edit dialog boxes and if I edit the City and save, it will then pop up in Saved Addresses but even after that it still will not fill in that field. Another strange thing is that when I go back to Settings it will have disappeared from SA leaving only the Name and Address lines as it was before the editing. Besides that and the jumping down 3 pages while scrolling down on long pages like Reddit, Firefox is perfect. It also seems that I may be the only one experiencing this judging by my many fruitless Startpage searches. Also neither of these issues are new to version 100 running on W10e64. Has anyone seen anything like this? Thanks in advance for contributions.

Firefox 100.0 Ubuntu 22.04 Mozilla VPN 2.8.0

As the title says, Multi-Account containers doesn't detect the VPN, which means that it's not setting the VPN for specific containers.

I suspect this is actually a problem with the "Allow extension to exchange messages with programs other than Firefox" permission. Could be a VPN issue, but gut feeling that it's a Firefox issue, TBH

Anyone else seeing this?

This happen only on Firefox. This has never happened on Chrome or Safari. I can be reading something and suddenly the page gets huge. The only way to fix it is to "X" out and go back to the page. I have called Apple support and we did a screen sharing with one tab huge and one tab normal so they could "see" this. It only happens in Firefox.

I uploaded an image of this but after 10 min it is still going around and around.

It seems since Firefox 100 the address bar has taken to being white-on-white, making it nearly impossible to read. There isn't any issues with light themes. It doesn't matter if I change the Windows 10 default app mode to light or dark. Light themes have black text on white background, but dark themes have white text on white background. Any ideas?

When i have like 50+ tabs pinned then firefox breaks and we cannot scroll tabs anymore. Of course closing tabs doesn;t work with Ctrl+W, but then we need some different shortcut for closing pinned tabs (like for example Ctrl + Shift + W) or just you fixing this bug ;) I attach 2 screenshots that show what happens with Firefox when having too many tabs pinned. I can't navigate through tabs anymore.

After update I am no longer able to open a new tab with the "add new tab"button, nor with the Ctrl + T command. A new tab will open if right clicking on a Link on page or search result and selecting/scrolling to "open in new tab". Win 7 (64bit) , FireFox Browser build 100.0(64 bit)

I have recently updated to Firefox 100. I am now getting this message on a page "You are using an outdated browser. Please upgrade your browser." I have confirmed I am up to date.

The "update you browser" has a link to "whatbrowser.org", which I believe is run by that horrid business, Google.

Has anyone struck this problem? Is there a solution?

I have closed Firefox & re-opened, I have rebooted the computer. No change.
