In the current Version of Firefox the input field is set to the wrong filetype if select an csv file.

Open with Chrome and Firefox. Chrome set the file type to text/csv Firefox to "application/vnd.ms-excel"

Working example open the consoel to see the output: https://codepen.io/GrizzlyStu/pen/YzjZjez

YouTube videos on Firefox getting slower and jerky. After refreshing Firefox (Settings -> Help -> More troubleshooting information -> Refresh Firefox), it is OK, but only for a short while. Then the problem starts again. Same YouTube videos are running fine with Chrome at the same time.

Running Windows 11 Pro (Clean windows setup not long ago and the issue was there from the beginning.) German Language Firefox 116.0.2 Build ID 20230805021307 Intel CPU i7-1360P, 16 GB RAM, 1TB M.2 SSD

Would really appreciate a solution for the issue because I really like Firefox!

HI for the past four days I have been getting the following error message when attempting to load www.canberratimes.com.au

"Application error: a client-side exception has occurred (see the browser console for more information"

This is happening on my Windows PC only. I can access the site on my Firefox browser on IOS.

I am running the most recent version of Firefox 102.0.1 (64 bit).

This is the only site displaying this message.

Grateful for any assistance in resolving this.

Kind Regards, Peter

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.)

After start up Firefox I am not getting any audio. No other app nor browser has this issue. It does not show up in the volume mixer. I've made sure all apps, browser, drivers, and windows are up to date.

Bonjour, Depuis une semaine, j'ai ce message à l'ouverture de ma page d'accueil Orange, avec Firefox !! PR_END_OF_FILE_ERROR il n'y a qu'avec mon navigateur et pas sur Chrome ni Edge. Avant, j'étais le seul impacté par ce problème et maintenant les trois P.C de la maison le sont. Deux W11 et un W10. En déconnectant le VPN le souci n'existe plus. Merci d'avance pour votre aide.

I am a game developer. I work about 12 hours a day, in Chrome. It is my main browser. When I installed firefox, I was asked to "import" cookies and such. I did. Which has been a terrible headache. All of the bookmarks and everything from Chrome came with it, which I already had in firefox, since I've had it for years. But, I thought since this is a brand new computer that I needed to do that. Fast-forward a couple of weeks and now EVERY time I open up firefox, all 10 million history links are in history.

I use firefox to unwind and watch movies. I don't want 10 million links to work in front of where I left off in binge watching Seinfeld.

I've tried everything and followed instructions and STILL, all history from Chrome shows up in firefox. It is infuriating. AND uninstalling and reinstalling did nothing. The setting is already in the account to import from Chrome to firefox. I've removed addons and extensions as well. Nothing has worked.

First time ever. Tested other browsers, sound works fine. Changed no settings when it suddenly went silent. Refreshed. Uninstalled/reinstalled. Nada/nothing. So to not feel as if I've lost my hearing, I won't be using Firefox until there's a fix on their end, already tried everything suggested in troubleshooting and refreshed. It's just not playing well with Win11.

I have seen multiple copies of this question, some unanswered, some with the same "answer". All the questions are closed so I cannot reply to them. The "answer" does not work.

I have the "Show tabs from other devices" sidebar. I also can access from "Open application menu" > email address > list of synced tabs. Both methods show me the device name and all of my synced tabs. Neither method has an "open all tabs" option. If I right click my device name nothing happens. If I right click a tab, it opens that one tab. I don't know how many tabs I have on my Android. I have enough tabs that it only shows the infinity symbol instead of the number. It has shown the infinity symbol for a long time and I've opened many more tabs since. It could be hundreds or even thousands of tabs. I have 224 tabs on my laptop. I want to open all 224 laptop tabs plus all however many Android tabs on my laptop at the same time. I'm aware this will cause significant lag on my laptop. I'm not looking for a solution for that or people telling me not to do that. I want to know how to open all of my synced tabs at once on my laptop, without having to click through one by one.

Edition Windows 11 Home Version 22H2 Installed on ‎2022-‎09-‎21 OS build 22621.1702 Experience Windows Feature Experience Pack 1000.22641.1000.0 "You're up to date Last checked: Today, 17:15" (Just clicked "Check for updates")

Firefox 113.0.1 (64-bit) "Firefox is up to date"

When typing, Firefox will lag and not display the words until much later, making it hard to know what I'm typing. This applies to any app that I'm using on the browser. For example, I typed this whole paragraph before a single word appeared, and even then, it still took another 30 seconds to actually appear. I've already reset, refreshed, uninstalled and reinstalled, updated, everything like that. I have a couple extensions, AdBlock, Honey, WebRTC Lead Shield, and Return YouTube dislike. But I ran it in safe mode and the issue was still there. I'm running the latest version of Windows 11 if that makes any difference.

I've worked with Firefox for several years, and had it opening maximized. I recently manually resized the Firefox window to facilitate some work in which I needed some other windows visible. However, now I can't get Firefox to open maximized. Instead, it opens a window going from the left edge of my screen (see the first image below) about a third of the width of the monitor, and it is showing the double box icon in the upper right corner indicating that the computer "thinks" it is in full screen. If I click that double box, the window immediately shifts to the right edge of the screen, occupying a space about a third of the monitor from the right edge, and shows a single box in the upper right corner of the window. If I click that single box, the window finally does expand to full screen, showing a double box in the upper right corner. I've tried all the manipulations I've seen concerning starting screen size (such as going to the shortcut icon properties and indicating the that the program should start "maximized") but I'm still getting this same behavior. Any thoughts? (I'm running Windows 11, with the latest version of Firefox.)

Hi @all,

I reinstalled my computer from scratch with Windows 11, before this reinstallation I had Windows 10. Now I noticed that with the newest Firefox version 109 (that I also had before with Windows 10) and Windows 11 my multirow bookmarks toolbar doesn´t work anymore. Before the reinstallation it worked with the following code:

/* Source file https://github.com/MrOtherGuy/firefox-csshacks/tree/master/chrome/multi-row_bookmarks.css made available under Mozilla Public License v. 2.0
See the above repository for updates as well as full license text. */

/* Makes bookmarks toolbar span multiple rows */

#PersonalToolbar{
  --multirow-bmb-n-rows: 3; /* Control how many rows are shown before scrolling */
  --multirow-bmb-row-margin: 2px; /* Control how much spacing is between rows */
  max-height: none !important;
}

#PlacesToolbar > hbox{ 
  display: block;
  width: 100vw;
}

#PlacesToolbarItems{
  display: flex;
  flex-wrap: wrap;
  /* --uc-bm-padding is defined in autohide_bookmarks_toolbar.css */
  max-height: calc(var(--multirow-bmb-n-rows) * (5px + 1em + (2 * (var(--multirow-bmb-row-margin) + var(--uc-bm-padding,2px))))) !important;
  overflow-y:auto;
  scrollbar-color: var(--lwt-accent-color) var(--toolbar-bgcolor) ;
  scrollbar-width: thin;
}

/* Hide the all-bookmarks button */
#PlacesChevron{ display: none }

/* Add some spacing between rows */
#PlacesToolbarItems > .bookmark-item{ margin: var(--multirow-bmb-row-margin) 3px !important;  }

I already tried some other codes that I found in the internet but none of them worked. I have this code in the file userChrome.css, this file is in a chrome folder and this folder is in my profile folder. Can anybody tell me what I have to do to make the multirow bookmarks toolbar working again?

Best regards heusmich

Recently the V-like icon/button appeared at the right-hand end of the top line of my Firefox windows. This Tab Search could be invaluable to some, but I have no need for it. If I start to get too many tabs I just use another window. However, I click on it constantly when I intend to minimize the window. I have been clicking on the - icon/button in EVERY WINDOWS APPLICATION since Windows began, and as it has ALWAYS been the LEFT-MOST item in the UPPER RIGHT CORNER I haven't had to think about it in decades. But now it isn't the left-most, that is now tab search.

Please, please, PLEASE provide a configuration option to remove Tab Search from the top line.

Thanks!

I noticed some peaks of usage on both internal and dedicated GPU while watching videos on YouTube. This happens only when watching videos not on Full Screen mode. I tested also with chromium but there's not this issue. What is causing it? How can i stop this behavior?

An error occurred during a connection to www.facebook.com. SSL_ERROR_DC_EXPIRED What in the world? does Facebook not keep up with its own security? or is this a Firefox thing?

Hi

Well Firefox did it again. I had tabs on the bottom where I wanted them and they broke this again in the update I just got.

Any idea how to move them back down to the bottom? This is the userchrome.css coding I was using that worked fine before the update

/* Modify to change window drag space width */ /* Use tabs_on_bottom_menubar_on_top_patch.css if you have menubar permanently enabled and want it on top

• /

/* IMPORTANT */ /* Get window_control_placeholder_support.css Window controls will be all wrong without it. Additionally on Linux, you may need to get: linux_gtk_window_control_patch.css

Hello,

Clicking to open Firefox gives me the following error message:

Error. Platform version '120.0.1' is not compatible with miniVersion >= 120.0 maxVersion <= 120.0

Can't open firefox! I'm running Windows 11 version 10.0.22631 Build 22631

Thanks! Julie
