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

This is more of a convenience issue but the new download panel pop-up from the download arrow is very distracting. I couldn't find an option to turn it off so I had to go into the config and turn the true flag false for this "improvement". Is there a better way of disabling this pop-up and if not will there be in future versions of firefox?

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

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

Had Firefox update a few days ago, which resulted in the Firefox icon now showing as a stenciled square with a bold PDF written across it. Raised this with community and abuse yesterday and two days prior to that but the only answer I got was to understandably show eveidence of the new icon. But having captured an image, it seems the "add image" is unable to dispaly the image. This info was also transmitted in my responses but with no reply from Firefox or the firefox community. Surely Firefox has the means to ensure they receive the image to evidence the problem I have. Email might ensure I can transmit an image. Equally Firefox doesn't seem to respond after a website has been found and I explore the site for additional information (eg shopping sites) but hwen I try to go back to the previous page of that website the previous page option doesn't work. Right now I don't know what version of Firefox has been updated or whether it is 100% genuine. As a matter of urgency could you please contact me to resolve my concerns.

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.

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.

I don't know if this is a problem with my installation, but websites without specific favicons (e.g.: https://forum.librivox.org/index.php?sid=fd7dca1ba59c207dd25121695677d565) don't have a placeholder icon in the tab. Is this intended behavior? There's the globe icon for bookmarks without favicons, couldn't that be used if a website doesn't have one? I think that would contribute to some visual consistency :)

I have looked across various support forums for information on this, I only see posts regarding favicons and bookmarks, not the tab itself, so apologies if this has been asked and answered already!

I was trying to solve a hanging issue with firefox and following a 'tip' I changed the name of places.sq.lite to places.sq.lite.old I figured the renamed file would be there to back-up from if something went wrong and although the hanging issue seems to have been fixed I have lost hundreds of links that have taken ages to put together.

Where is sq.lite.old located as it is missing from the original folder? It is not in my recycle bin so renaming it to old hasn't simply deleted it. In another folder there are bookmark backups with dates (JSONLZ4 files) but I have no idea how to get my old links back from them, if indeed that is what they are for.

Please help.
