Firefox supportforum

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 Adblocker Ultimate as an add-on. But I can't seem to put it in my toolbar. I have searched the internet to resolve this problem and nothing worked. It is listed in my Add-ons manager but I can't get it to show up in any bookmarks or the toolbar. It does work but I can't find it anywhere.

what the hell is wrong with firefox windows? /all my extensions are not showing in my toolbar. No themes are showing correctly. Just more problems to work around, as if I have the time, to go along with the "improvements" for my life?

Okay, Mozilla Firefox seems to be very safe. BUT then you took away so much that now I have to have extensions to do what I want. But every time I go to look at an extension, I see a warning that Firefox does not monitor it for safety or security. So basic - Firefox is no longer safe and I cannot have a good experience unless I take a risk? Why can't Firefox have its own extensions?? How can I determine that an extension is safe before it is too late?

At one time there was a userchrome patch which could be applied to obtain legacy-style square corners on the URL bar and the search bar. I can not get this to work despite trying several different suggestions and I suspect it may be related the the Proton redesign.

Can anyone suggest a userchrome mod to obtain the desired square corners?

When I put something in the search box it comes back with a Google Search 'hit' page and it always has enormous text, an enormous font. I can't get rid of it. It started after one day I couldn't read a tiny text on a page so i googled for help and got some keystrokes for increasing font size. i forget what they were but they worked fine. But now I can't get rid of it. On all other pages, yes, no problem. I found keypresses that are supposed to get rid of large font: ctrl-z, ctrl-y, different ones different places say, I"ve tried them all, but can't get rid of the big font on the first page of a google hit. I am using firefox of course. On a linux mint machine.

I need to follow many hyperlinks. Everything worked fine and the followed hyperlinks changed from blue to purple. In the last 2 days, they stay blue. I have gone to settings and reset it multiple times, but the only way I can get the change is to make the screen high contrast, which I do not want. I have refreshed Firefox. I have the latest update (which might be what changed). What is the problem?

How do I add the icon for an add-on which is not shown when I click on "customize toolbar"? When I click customize toolbar the result does not show any of the icons for add-ons/extensions.

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.

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

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 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?

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.
