Forum pomocy dla programu Firefox

I took a video on a Google Pixel 7 mobile. It plays back on the Android cell properly. I can log into my Google Photos via my Windows 10 PC and the video will play back properly. I also downloaded the video file (MP4) to be saved directly in my Videos folder on my Windows 10 PC. When I try to play the video by clicking / opening the downloaded file on my PC I get an error message. See that message attached. It is prompting me to "download a new codec". Why? In my Firefox browser I currently have the Open H264 Video Codec by Cisco plugin enabled. Why is the Cisco plugin not sufficient? Is the Cisco plugin being updated? Does Firefox browser need to be updated? Is Is Firefox working on a fix?

How do I get rid of the purple home page in Private browsing that really defeats the purpose of private browsing when everyone can see this page pop up??? I have tried setting it to private only and I still get this page upon opening. I have searched the FAQs and tried all that they suggest (except for the one that suggests not using private browsing at all). this question and problem go back to at least 2019 it seems to me it should have been FIXED by now.

I am using theme called WhiteSur to imitate Safari, as that is the browser layout I prefer. However, this doesn't change the position of the close tab button and leaves it on the right hand side. I found a way to change it, using the code .tabbrowser-tab .tab-close-button {

 margin-left: -5px !important;
 margin-right: 2.5px !important;

} Unfortunately, this doesn't change based on the size of the tab, so if I set it to a size that is good for only having 1 tab, it will look bad or be off the screen for the other amounts of tabs. Is there a way to detect the width of the tab or the amount of tabs open and dynamically set the margins based off of this? So I could set it as (width-of-tab)-x and that would always keep the close tab button in the same spot, regardless of tab size. Thanks!

In HTML, in the head element, it is possible to specify links to external resources that are relevant to the current page. For example:

<link rel="alternate" type="application/pdf" href="mypage.pdf" title="My Page in PDF Format"> <link rel="license" href="copyright.html" title="Website License Information"> <link rel="next" href="page2.html">

Many years ago, I found an obscure setting that enabled a toolbar that would display all those document links directly in the browser. That was several computers ago, so I cannot look up the about:config setting that enabled the functionality, and my online searches have found nothing even remotely related to the subject.

What happened to that functionality? How can I turn it back on inside the latest version of Firefox?

Addendum: This functionality was not provided by any extension, add-on, or mod. It was implemented directly in the browser itself, downloaded vanilla and clean installed. It was enabled by directly editing the "about:config" page.

As for whether the cited links are intended for automated tools or not, here is the HTML standard itself:

Interactive user agents may provide users with a means to follow the hyperlinks created using the link element, somewhere within their user interface.

And just in case somebody suggests this is somehow new or novel functionality, here it is described in the HTML standard published in 1997:

Although LINK has no content, it conveys relationship information that may be rendered by user agents in a variety of ways (e.g., a tool-bar with a drop-down menu of links).

That "tool-bar with a drop-down menu of links" is almost exactly what Mozilla used to provide. I just want to know what happened to it.

I've been using Chrome for a long time, and I've been slowly switching over all my bookmarks, passwords, etc to Firefox. I'm running Linux mint for context.

Every time I open Firefox, it opens the home tab, and after a second or two it opens Mozilla Rally in a new tab, and it drives me ABSOLUTELY BONKERS, because I get halfway through typing in a website, and I'm redirected to this new tab I care nothing about, and for some reason cannot get rid of it in the minimal startup settings that actually exist.

That's some straight up Microsoft Internet Explorer sh!t there, and yes that was meant as an insult.

I have not been able to find any reference or any way to make that not happen, and it is seriously making me consider abandoning Firefox entirely. Don't make me go back to Chrome.

Please help.

My elderly client has enabled a “my tasks” sidebar in Gmail. He does not know how to turn it off. I have searched for an answer and have been unable to find one. Ctrl+B is not helpful and doesn’t bring up a screen where it says sidebar. Please help! He keeps asking about it and I am a caregiver, not a computer technician…

Hello, I am wondering if there is any way to lock the toolbar so that it does not automatically pop up when you are in full screen mode and hover over the top area of the screen. I cannot easily play some browser games because they must be full screen and the toolbar popping up continuously interrupts the game.

To clarify, I do not want the toolbar to always be there; locking the toolbar so that it automatically shows when in full screen is not the solution I am looking for. I want the toolbar to disappear when I am in full screen and not popup when I hover over the top area of the screen.

Thank you for any help!

I have a keyword, "ht", for the OED's historical thesaurus. Here is the keyword's URL: https://www.oed.com/search/dictionary/?scope=HistoricalThesaurus&q=%s&tl=true

But it exhibits very strange behavior. When I enter "ht test" in the address bar, it goes to https://www.oed.com/search/dictionary/?scope=HistoricalThesaurus&q=test&tl=true and (for some unknown reason) returns a 403 error. If I refresh with F5 and resend, I get the same error. However, if I simply Alt-D into the address bar and press Enter, it goes to the very same URL and returns the webpage as desired, with no 403 error.

Does anyone know what's going on, or how to make the keyword work properly from the beginning? Thank you!

I turned off the translator popup via about:config and browser.translations.automaticallyPopup to false. Now translation is gone. How can I keep the option to quickly translate a page in the address bar without having the popup jump in my face each time I open a new tab, forcing me to click it to make it go away? This would be a nice option but an extremely distracting presentation. thanks.

When I left-click on text and hold the left mouse button, then right-click, first release the right button, then the left button, a "selection mode" is activated, where the end of the selection follows the mouse pointer despite no button is held. In principle this looks like a useful feature (or it would if the scroll wheel worked in that mode, which it doesn't). But at the same time, the context menu opens when the right button is released. So we trigger two features at once, making both less useful, because they're getting in each other's way.

This frequently happens to me when double clicking on a word and right clicking to open the context menu on it. Accidental overlap of the left and right clicks triggers the selection mode.

Can this behaviour be configured (e.g. to use a custom shortcut) or, if not, be deactivated entirely?

I'm using Firefox 123.0.1 on Linux (openSUSE Tumbleweed).

I am looking for a fix to get my metamask wallet working again on firefox. When i click on the metamask icon all I get is a spinning wheel. I am not able to login and access my my metamask wallet. I am hoping to find a fix prior to performing a recovery with with my seed phrase on another desktop. Any assistance would be greatly appreciated!

I had Firefox set to load 4 tabs when started. Something has changed recently and now it seems as if the same 4 sites keep repeating somehow. I have set the Home/Custom URLs to these 4 sites, but cannot prevent them to load again when already loaded.

I moved to Firefox because I have autism and someone told me it would help block the popups and moving content that makes using the web exhausting and difficult. And it does!

The trouble is, it replaces them with something worse – a grey screen that rolls continuously from left to right. It's impossible to focus on text with such intrusive visual distraction, so I have to shut the page down. It seems to occur on so many websites that at the moment it's not worth trying to use the browser.

Half the problem is that I don't know the right term to describe it, which makes troubleshooting a bit complicated. Hopefully someone will recognise it from the description, though – if so, is there any way of stop it moving, please?

Thank you!

For years I've been able to input a website keyword (let's say "cnn" like in an old report I ran across) and the "www." and ".com" portions would be added without my typing them. Some time ago, this started to fail. Why?

I tried about:config changes that were said to work with the old "cnn" problem report but nothing helps for me.

Also, I use the local Windows Hosts file to give my router a quick reference name to get into it. That too has worked for years but began to fail last year. Inconvenient. The best I could track this down, it has something to do with forced DNS lookups and skipping the old Hosts file. If so, any work around to get my system simplicity back?

Help is appreciated. I liked the challenge of computer geekdom 30 years ago but I'm getting too old for this, well, you know the old saying.

Trying to download and print one of my tax documents. File type is PDF. Even in the print preview, the right margin is at least two inches, and it prints that way. I tried clicking "more" and adjusting the margin settings, but that doesn't help. I tried printing through Chrome and Edge and it prints fine. Any ideas how to get PDFs to print right on FF without having to switch over to another browser to print a document?
