I am sorry if this is not the place to ask this question. I am new to web development and have been trying to solve this issue for days. I have an ESP32 acting as an http server. I have developed web pages which have separate html, css, and javascript files. These work as expected when delivered locally (i.e. I double click on the the files), however, when they are served by the ESP the style sheet is ignored and I get the message

The stylesheet (url) was not loaded because its MIME type, “text/html”, is not “text/css”.

from Firefox debugger. The stylesheet is ignore across all browsers (Firefox, Chrome, Opera, Edge), however the error is only shown in Firefox. Normally, of course, I would expect an issue on the ESP32 side, however, the non-Firefox browsers do load the stylesheet (even tough they ignore it) and I am able to verify that the stylesheet is identical to the one served locally.

Oddly, if I open a Firefox tab and load the page, switching to developer mode causes several requests for the stylesheet and the styles are then applied. Subsequent refreshes of the page causes the style to be lost and closing/opening developer mode has no effect.

Although I have disabled javascript to try fix this problem, when javascript is loaded I get a similar message (except the javascript is loaded).

I believe I specified the MIME type because I exactly coped several examples

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8"/> 
    <meta name="viewport" content="width=device-width, initial-scale=1"/>
    <link rel="stylesheet" type="text/css" href="styles.css" />
<!--<link rel="stylesheet" type="text/css" href="name-of-stylesheet.css" />    -->
<!--    <script type="text/javascript" src="ESP-UI.js"></script> -->
    <title>My ESP32</title>
</head>


Thanks for the help!

Wikipedia render Thai fonts correctly. But it seems to render Latin texts and numbers in "TH Charm of AU" font for Thai articles, which I did not set anywhere in the browser (and my operating system). Ticking "Allow pages to choose their own fonts, instead of your selections above" does not fix it either. But it renders fonts correctly in English version of the same article. (See the attached images).

Any ways to fix this?

Thanks in advance.

Recently, I've been noticing an issue with Firefox's built in Picture-in-Picture (PiP) feature. When watching media, such as a YouTube video, using PiP, the video runs as normal, but recently, the PiP completely breaks when I tab away from my Firefox window to do something in a different app. This wasn't the case a few months ago, so I'm not sure what changed to make this error happen. I had attempted to disable hardware acceleration to see if that was the issue, and nothing changes when it's enabled versus when it's disabled.

When using the PiP feature is there a way to switch whether it pauses the video when closing the PiP player?

Often if i want the audio to continue but dont want the popout player there and if I press the close button it will just stop the audio. If I select the PiP window and use the shortcut CTRL + SHIFT + ] the audio will continue playing as I want it however this is inconvenient and requires using the keyboard, is there any way to change it so that closing the popout player doesn't stop the tab from playing audio?

Hello. For a while now I have been using the picture-in-picture feature to play a video in the corner while using other applications. It has been a great help as I have a single monitor.

Unfortunately, I have recently been encountering a severe issue with the feature over the last week. When attempting to use picture-in-picture while my computer is running a videogame (through Steam) my entire system will freeze. The audio still plays as normal, but the image is frozen and the system is unresponsive until I force a shutdown and reboot.

Any help at all in with this issue would be greatly appreciated, thank you.

When I encounter an embedded video on a website that plays, an icon to toggle picture in picture pops up in the URL bar (see attached image). I don't use picture in picture, and for some websites which have an "endless scrolling" experience with videos, such as reddit or facebook, it is slightly annoying that while I am focusing the middle of the screen, something changes in the top right, making me think a tab has an update and changed title. I have the picture in picture controls turned off in settings (one with the id=pictureInPictureToggleEnabled in general, my Firefox is not English), I thought it would also make said button go away but it does not.

Can't use YT picture in picture mode on Firefox when logged into my YT account. When I enable picture in picture on a video and scroll down to the comments, picture in picture mode turns off as soon as I scroll past the bottom of the video.

Happens only when I'm logged into my YT account on Firefox. Logout, it works. Logged in on Edge, it works. Logged into my second YT account on Firefox, it works. Only doesn't work for this one account.

Attached images if that helps. Last image shows exactly when picture in picture mode turns off when I'm scrolling

I am experiencing an issue with the Picture-in-Picture (PiP) functionality in Firefox on Ubuntu. Unlike on Windows, where the PiP window automatically appears when switching tabs or pages, this does not happen on my system.

When I manually activate the PiP feature by clicking the button, the window does appear; however, it is placed behind the browser window and remains at the lowest level among other open windows. This causes it to be obscured by other applications and requires me to manually bring it to the front and adjust its position every time.

Is there a way to automate this process or resolve the issue so that the PiP window behaves as expected (i.e., stays on top of other windows and works seamlessly)? Please let me know if there are any settings, extensions, or workarounds that could address this problem.

Thank you in advance for your assistance!

Hi all,

Just updated to version 142.0.1. I now have the annoying behaviour back that video's on a website pop out on the screen while scrolling on a webpage and they are in the way of the text. I don't want any videos popping out. In the past I had it resolved somehow, so it looks like the update "undid" these. If I'm correct I might have changed a setting in the about:config.

I found multiple articles stating to uncheck "Enable PIP controls" in the setings, section [General] - [Browsing]. This options was moved to the [Firefox Labs] section within the setting. This option however is already disabled.

This page does not resolve the issue: https://support.mozilla.org/en-US/kb/about-picture-picture-firefox#w_why-dont-i-see-the-picture-in-picture-toggle

How can I prevent a video popping out on the screen an float above the web page? I just want to keep it in the window\frame where it belongs.

Link of a page where I have the issue: https://www.telegraaf.nl/video/oprichter-sbs-hiermee-onderscheidt-sbs-zich/86683036.html Also attached a screenshot.

Thanks in advance.

Since a recent version of Firefox was installed the picture in picture control does not work. I have unchecked the option but It still shows in YouTube etc.

I know this can be disabled in about:config but I prefer not going there. I wonder if this will be corrected sometime, otherwise the setting option is pointless.

Another item: I have unchecked the search suggestions in settings but it makes no difference.

Input welcome.

I know that after PiP(Pitcure-in-Picture) is enabled, I can use it in two ways: one is the button on the right side of the address bar, and the other is the icon button floating on the video. I'm trying to figure out how to keep the PiP button on the address bar while hiding the icon button on the video. I do not want to turn off PiP, I just want to hide the icon button on the video. I tried setting it in about:config, but it only seems to have the opposite effect. If it's not possible to achieve what I want, where can I request this feature from Firefox?

Over the last 6 months, and increasing number of websites don't open on Firefox. I've noticed it most consistently on any of the wikipedia/wikimedia pages, but it's not just those. When I type in an address and press return, or click on a link, the browser just acts as if nothing has happened. There does not show me the loading symbole. If I ask it to open a new tab with the site, the address appears on the tab, but the page itself is just black. Other browsers have no problem loading the same sites. I am on a mac, and using a VPN. Restarting the browser doesn't help, though restarting the computer sometimes does.

Thank you,

We are unable to stop playback from the controls in the PIP window for Apple TV when the video playback was started in the main browser window. If we press the control the playbacks stops for a fraction of a second and continues again. Other controls like mute etc. are working as exspected.

If we start the playback in the PIP window we are able to stop it!

If we use Youtube or Amazon as a video source the problem does not show.

If we use Troubleshoot Mode we get exactly the same behaviour.

Any Ideas?
