Firefox Support Forum

Given that many innocent files are now being spoofed to be something other that what they appear to be, it strikes me as risky behaviour that if you stop Firefox opening PDFs within a tab in itself - in my case, because I prefer to use Sumatra PDF, and because I wish for Firefox to DOWNLOAD the file (but not open it), Firefox defaults to automatically opening it, when all you actually wanted to do with the PDF file was download it.

Regardless of what the web site is instructing the web browser to do, Firefox should remember who it's working for ;p If the user chooses to download only and not to open (perhaps because they wish to virus scan first) any file, then Firefox should provide an option disable auto-opening (with associated client) any file.

With the ever increasing risks of malicious files, this is more important than ever.

This occured with this file of sheet music, which is what prompted me to mention this. I have Sumatra PDF set up in Windows as my default PDF viewer.

Hi :)

I use Firefox on my Asus laptop running Windows 10. It's one of these laptops with both integrated and dedicated graphics (Intel plus Nvidia).

I often experience this issue when putting a video in full-screen (especially when viewing trailers on Steam, but this may just be because I mainly use my Windows laptop for gaming, and thus most of my video consumption here is from steam). This screen will briefly (for less than one second) turn black and audio will pause before the video appears in full-screen, and playback resumes normally.

It "feels" like a GPU switch is taking place, I'd assume from the integrated graphics to the GeForce card. This is not the proble. The issue appears when I return from full-screen mode. I always have several Command Prompts open with SSH connections to my Linux server and sometimes my MacBook Pro. These windows are now empty. That is, all text is gone, and I can no longer interact with the sessions. They're not "broken," as in they're not saying "Not responding" and don't ask to be forcefully closed, they're just black windows with borders around them. All I can do is close them all down and open new ones to reconnect and start over from where I think I remember I was.

I should note that this doesn't ONLY happen with Firefox videos going into full-screen, it has also happened after launching a game and returning to the desktop. This strengthens my belief that this has to do with GPU switching and/or video "mode" change(s).

Assuming I'm correct (my IQ is 5,000 and I do do the very big brians), is there any way to control how videos go into full-screen in Firefox? Or "lock it" to a specific GPU? I've rummaged through about:config and haven't seen anything that seems directly relevant.

I've already tried using the Windows settings to tell the system that Firefox.exe should use the integrated Intel graphics only, but this has no effect.

I remember I used to use "Media Player Classic" many years ago, and it had a slew of options of how to render full-screen video. IIRC, it had stuff like "Overlay," "Windowed," "Windowed borderless," "DirectX," etc. This make me wonder if there's multiple ways of chosing how to render video in full-screen, then maybe one could direct Firefox to use a different one than the default and my problem might disappear? Or maybe one could tell Windows that if an app wants to go into full-screen video mode, Windows should pick a specific mode for it?

I'm not a Windows developer, so I don't know :) But I'm hoping someone has a good tip, because I'm finding myself using this system more and more, and this is my biggest problem with it currently.

Thanks in advance :)

I have a subscription to a website to download music, and in the last couple of days I have been having problems with the download page.

The error message reads: Stuck? Please disable ad blocker extensions/plugins. Your browser has probably an inbuilt one too.

I have Ablkock Plus, Adblocker Ultimate and Ublock Origin insyalled on FireFox and have disabled all of them for the website in question - but all to no avail.

Suggestions please

Hello, I'm having an issue with my overflow menu. When opening the customization screen for the toolbar, I can't seem to drag certain toolbar elements into it? The buttons on the customize screen itself work correctly, and some of the elements present on the toolbar will change between visible and overflow just fine, but others I am completely blocked from moving. Please assist, as this is seriously impacting workflow.

As says on tin. I prefer to keep everything in the overflow menu, separating them is annoying. Also, itens in the add-ons menu are larger and less compact. How this layout change has anything to do with Manifest V3 I have no idea.

I have a new laptop so needed to install an adblock. The search results page gave many choices. However, no matter which one I clicked on it said this page is not available in your region. Now how is that possible seeing as on my previous laptop and in the same region I could install the add on? I have had to use a VPN to install the adblocker. Please explain how regions prevent the installation and why it happens. Firefox is universal or so I thought.

I have been using these userChrome settings:

 https://support.mozilla.org/en-US/questions/1365405

and now with the latest release, the close button is back to the right. That Mozilla doesn't follow the OS environment norms is utterly baffling, or at least provide a Setting for close button position. Can anyone provide a solution please?

Hello! I wanted to know if it is possible to disable the underlining of letters in the browser? As I understand it, this underlining is needed for easier page navigation, but I would still like to remove it.

Please add an option to the right click menu. I need to be able to open a page link, not to a new tab or window, but to a new instance of Firefox BUT without any extensions loaded. I ask this as many extension block links from running, but on occasion I need to open a link to a "clean" version of Fire fox, in order to see a blocked video or page. At the moment I have to copy the whole link and open a different browser! This happens a lot with trailer video links in IMDB.com

I've had a website as my home page since the 1990s. The website in question, https://www.elvis-collectors.com/, has followed me through Netscape, Chrome, two laptops and around five PCs in that time.

However, Firefox updated this afternoon and removed the home button. I restored it but cant find out how to customize the URL to go to my website.

How do I fix this?

Who decides on these changes??

I've been on the internet since the mid 1990s. I dont go to that site much as I used to but it reminds me of the early days on the net. It has always been there. Please help.

Hi all!

When I alt-click, I always want a new tab to appear, but in the background—never forcing me to navigate away from my current window. (I'm a Mac user, and use the Command key as my alt.) I've successfully toggled settings in about:config to make this happen in 90% of cases. But...

When I type into the address bar and hit alt-return, Firefox always forces the new tab into the foreground (whether a search result or a typed URL). How do I change this setting to background?

Thanks!

This may seem to be a senseless problem, but I don't see well and it's rather important to me. There is the search/address bar at the top of the screen. There is also the somewhat larger one down towards the middle of the screen. This is the one I use a lot. Recently, when I start typing in that lower box, I am immediately jumped to the upper one. This is something new. I cannot find a setting to prevent this from happening. (I have tried switching browsers - someone suggested that might help, but not so.) I would very much appreciate any ideas. Thank you.

I will be to-the-point: Firefox 109.0 has forced the "extensions" icon (a puzzle piece) on my Bookmarks toolbar.

(1) I do not wish for it to appear there (2) I am not given the possibility to remove it from the "Customise toolbar" screen

Please assist.

I am a new user to Firefox (started in Feb 2023). I am running version 110.0.1, Windows 10 version 22H2, 64 bit. I want to add more tabs (webpage links) to my Firefox Home Page. Firefox Help/FAQ says that I should select the address bar, enter in a website address, and then click on the "menu button" which is on the right side of the address bar. It is supposed to look like three dots or three lines. However, my address bar does not show that - or at least I can't find it. The picture provided in the online Firefox FAQ doesn't match what I am seeing on my home page. Please let me know how to get this "menu button" to appear. Thank you.

Point me somewhere that I can fix this. Last Pass used to have a large red item around where the pocket icon is in the top right but it doesn't appear now. I have downloaded "lastpass_password_manager-4.108.1.7.xpi" and tried to add it to the extensions. But nothing.

Thanks Bob Sawyer

Hey there! I am looking for a setting that sets the columns in the new tab page.

i know about: "browser.newtabpage.activity-stream.topSitesRows" This is the same as going to the settings and changing it in the drop down menu.

Is there something that can set the quantity of columns?
