Firefox Support Forum

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

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)

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.

when i browse this page https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flexible_Box_Layout/Basic_Concepts_of_Flexbox ,the monospace font show error, the detial please check fellow images. picture 2 is my font settings

Mozilla Firefox for linux Mint 99.0.1 (64 bit) - mint-001

Using Outlook web, when viewing pdf documents, it displays strange symbols (incorrect font sets are probably used).

I point out that using Chrome the problem does not arise.

I also installed the microsoft fonts thinking it might solve the problem I attach illustrative image.

'I am on Firefox and then log into PGA.org, who recommended I use firefox for all my educational activities, a giant clock shows up when the educational portal should pop up. I have asked the PGA about it and they have no idea how to fix this.

In each update there is, my browser is reset, the history, tabs, and all other data is lost with no way to get it back. I'm given no warning of when this will happen and frankly, this shouldn't even be an issue. This makes Firefox unusable and despite my love for this browser, I won't be using Firefox unless the issue is resolved.

I have lost several very important tabs and data, and this isn't the first time. This has happened since I got Firefox. This ussue makes this browser unusable and unreliable.

Website changes when developing never show the change even with cashing is operative. Regular history cleaned ETC ETC - Means CACHE CLEARING NEVER WORKS. This is a VERY BAD PROBLEM that is quite common. How these idiots at Mozilla have never fixed it indicates they useless. I've been recommended NEVER to use firefox because of this issue. So its back to Chrome and I hate supporting Google.

SSL_ERROR_ACCESS_DENIED_ALERT I keep getting this on different sites, I can't access lots of pages and it's getting to be a massive problem and I reallly need some help. PLEASE can someone help.

I haven't traced this to FF updating, so don't yet have a hunch on what is triggering this:

Browser: FF for Win.

ISSUE #1: Downloads are going to the default location (Windows Downloads folder) in spite of being set to 'Always ask you where to save files'. This setting is retained correctly, but the browser is NOT asking me where to save the downloads - it just puts them in the default Windows "Downloads" folder)

ISSUE #2: I NEVER have ANY browser save passwords, yet despite repeatedly setting it NOT to ask to save passwords, here I am AGAIN setting it NOT to save passwords. This seems to happen every few months, but I don't yet relate it to FF updates.

Thoughts?

Thank you, Doug
