Subtitles in picture-in-picture are doubled. I've tried clearing the cache and restarting the browser but the problem persists. Site in question is Netflix (first image). Does not happen on YouTube (second image).

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".

Since about 2 weeks ago many AOL attachments are not opening (pdf.s are but others eg Word not). I have read thru' previous messages on this (in 2021) but turning off enhanced tracking has not fixed it. My attachments open in Edge and Chrome. Like others I would like to stay with Firefox but cannot live with this problem. Help please

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?

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?

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.

I got mad at a website that wouldn't let me right click menu to save pictures, so I stubbornly saved them via less efficient means, in the process I picked up the Long Screenshot extension and this had an error shortly before or after I had an issue with Lightshot not appearing, other extensions did not appear either when I added them during this time period, but now these all appear with the exception of Lightshot, which gets deleted and reinstalled only to not appear, that of course being the problem, though I will also say that a right click menu not being there is like reaching onto my computer and pulling my finger away, sites that do that should be given the cold shoulder somehow, at least.

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 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.

Hello dear volunteers (followers),

After Firefox Update to 100.0, the Theme that I created (JOHN - Light Grey) stopped working properly. More Specific all drop-down and pull-down menus have been transformed to a "white" background color, overcoming the initial created one, which was "dark gray".

So I tried to revise (update) my "Theme". But this became impossible.

In Developer Hub, in Theme Generator there was a (pink) frame warning "the following manifest properties that your most recent version upload used in it's manifest are unsupported in this wizard and will be ignored: properties popup popup_text tab_loading So I couldn't edit the theme and even more I can't finish and save any changes. Well, Is there any skilled user to give me a hand ? I would appreciate too much any piece of advice ...

Herewith I attache relevant screenshots.

Thank you in advanced

I went into about:config and changed the following values in order to widen the scrollbar:

css. scrollbar-width was true changed to false idget.non-native-theme.scrollbar.size.override was 0 changed to 100 widget.non-native-theme.enabled was true changed to false

Changing these values didn't widen my scrollbar. Without getting into coding, is there another way to make the scrollbar wider? (I changed them all back to the original settings when they didn't work.)

I would like to stop the default behavior of firefox displaying in the tab that contains my GMail how many unread GMail messages there are -- in other words to delete "(9)" from the attached photo and never have the count displayed -- if it could instead simply say "Inbox - xxx@gmail.com"

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.

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.

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

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.

Using FF 100. Last week the Washington Post suddenly will not display article content correctly. Main page is fine, but when I open a story, I get code and a page with many blank areas. Story content appears with small print.

No problem in Edge nor Chrome.

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
