Firefox supportforum

I've tried everything to fix poor picture quality when streaming "third party" videos, e.g., YouTube. Colors are washed out; weird contrast; everything looks like it's coming through a haze. Streams from Netflix, Amazon look normal. And sorry, guys, the same third party streams from YouTube et al. look totally normal in the MS Outlook browser. Have tried all kinds of settings and rebooted as well. No change.

Please advise. This problem appears to be unique to 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

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!

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 have bought a new pc with Windows 11 home pre-installed and set Mozilla Firefox latest version as default browser ...the issue i am having is placing add-on extension shortcut icons on toolbar. I installed Norton Safe Web and this installed ok and is listed in extension control panel and when i click puzzle icon Norton Safe Web is not shown under manage shortcuts nor can i see option to Pin to Toolbar. Have tried several attempts but still get nowhere.I uninstalled Mozilla Firefox...restarted pc ... did a fresh install of Mozilla Firefox without altering any settings..re-installed Norton Safe Web and still cannot see option to Pin to Toolbar.Clicking the gear icon does not help Have i missed a step somewhere ?

I am unable to sign into Microsoft 365 services in Firefox. When I try to sign in on the Microsoft 365 Website, it doesn't sign in, it simply redirects me back to the website. When I try to sign in from the Outlook login page, I get an error page saying "500 Something went wrong. Repeating redirects detected." Screenshot attached.

1. I was able to sign in with another browser. 2. I was able to sign in on a device running Windows 10. 3. I have cleared the entire cache and history on the Firefox browser - it didn't work. 4. I tried logging in with Firefox in Troubleshooting Mode - it didn't work.

I saw an archived thread from 10/28/2021 where @OthelloBloke had the same issue ("Microsoft 365 Signin on Office.com Doesn't Work After Windows 11 Update"). It didn't seem to have been resolved. It has been a while since Windows 11 came out. Has there been any resolution to this issue? Please help me fix it. Most of my activities are on Microsoft 365, and I prefer to use Firefox as my browser. But if this is ongoing I will need to abandon this browser in order to access my work.

Audio on my PC works except on the firefox browser. The browser is not muted, I've checked the volume mixer, i've reinstalled firefox, but nothing seems to work. This just started occurring a couple days ago. When I restart the pc, i will get audio from firefox for a couple seconds then audio stops.

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 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?

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

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'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.)

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.

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

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.

Hey there,

I have been using the arrow keys to scroll pages more and more often and was wondering if there is a way to increase / decrease the speed when holding down the arrow keys to scroll the page?

Thanks in advance. :)

Hello,

My old PC crashed and I want to transfer my bookmarks from the old hard drive to my new PC running windows 11. I have unlocked hidden files, but when I ran drive:\Users\username\AppData\roaming\Mozilla\Firefox\Profiles nothing came up. I then ran places.sqlite and a list of places.sqlite appeared with some files having -wal &-shm after them?

I believe from reading here this is where my bookmarks are?

If so, how do I transfer them to my existing PC hard drive to use please? Many thanks Chris
