Firefox Support Forum

I have seen this in some past versions of FF It usually goes away after a few upgrades

Instead of whatever it's supposed to display, you can see that it shows some random characters.

Annoying. I dont even remember what it's actually supposed to show

Hello,

I have autofills and login savings disabled, but browser still seems to be saving form data including usernames. How do I disable browser saving any form inputs altogether?

Hello, I just installed windows 10 on my nephews computer. I installed firefox so I don't have to use edge, but firefox won't start. It just flashes. I have tried re-installing firefox, deleted all mozilla and firefox files and folders and clean installed firefox, even reinstalled windows. Troubleshoot mode don't work, it just flashes too. I checked for Crash Reports, but there are none. The only time it works is when windows is in safe mode, I even upgraded to computer to windows 11 hoping that it would fix what ever is going on. But it didn't. I honestly have no idea what to do next. Firefox has worked on that computer before. Everything else works fine, it's just firefox that won't work. If anyone has any ideas, please let me know.

I can only save (not open) Gmail attachments after the latest update and JPG is not showing up in my the Applications section of Settings/General so I cannot fix it.

This has happened one time too many guys, every update but this time half the items I would normally get as an attachment are no longer listed in the applications menu.

If I cannot get a fix quickly I will be forced to move to Chrome (which I REALLY hate the idea of). I see 25 - 80 emails a day and it is mission critical that I can open and view email attachments without having to save them.

A little help??

Downloaded the latest version of FireFox, and have somehow lost the toolbar for my bookmarks. Have tried suggested things mentioned that i can find to no success. How do i get this much neede item back, HELP please?

In the past, there was a helpful link to the right of the address bar that enabled me to email a link to the current open page to my friends. That link is missing in the latest version of Firefox for Windows. How do I restore it?

I've noticed for some time now that when I access the history tab and see what there, there is nothing in it. In the past when I accessed it, it would show the sites I had visited. Not any longer. How do I fix the problem?

My Firefox has suddenly stopped working when websites have menus you need to scroll through on the right side. Example: websites where you are drilling down through filter options, or in Ancestry where you will typically open a record in the hints screen and scroll down through the detail. The right scroll navigation causes the whole page to scroll up and down; there's no way to navigate down in the sub-display. I have run FF in safe mode, and done a scorched-earth uninstall/reinstall and the problem persists even with no plug-ins restored. This is on a machine running Windows 11. The machine crashed right before this became a problem. Sites work in Edge without issue.

I use firefox since I go to college. When I got some problems, I try to check firefox use what to pick folder? I use Manjaro Plasma. I find chrominum use kdialog. But firefox looks not though both use gtk3 as UI

Firefox choose folder got wrong when use a USB HDD

Hey, I can't add new filetypes to the handlers.json Who had this before? I have already reset Firefox, deleted handlers.json, used safe mode... all without success For example, when I click on a ZIP file, the "save as" menu opens immediately. In the FF settings this filetype does not appear. So I can't define how to handle new files. I have also tried the addon "Content-Type Fixer Content-Type Fixer".

I have set the Noto family of fonts to be the default font family but websites that don't specify a font or specify sans-serif or monospace get Liberation Mono. When I changed any option in the fonts settings, the entire browser becomes Liberation Mono. I want Noto Sans be the default font for websites and for the Firefox UI. I tried to fix it by preforming a Firefox Refresh, but it didn't work. I think the problem began after upgrading to Firefox 100 but I'm no 100% sure.

The included pic shows the red screen that comes up when I hold shift down when the mail composer is up, this is one of several like errors like a hover over text one and auto save one which crash the page nearly and require reloading of the page, another error is that the close, minimize and maximize buttons are missing when protonmail site tab is both active and maximized, not when minimized, then it is the same as the rest, support and I were not able to resolve this, I picked up some Java replacement extensions and whatnot and that did not work either.

Hello,

Firefox just updated to v100.

However, my menus (e.g., bookmarks, tools, history etc) and popups text has become black, having previously been white. The Menu Bar and Tabs text are still white.

How do I get the White text back on menus and popups please?

Thanks in advance.

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

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.
