Many web pages that have a video header will launch the video in a popup window after you scroll past the header.

There are no user controls in the popup window, and clicking 'block popups' and turning off 'enable p-n-p controls' had no effect on them.

Is there a a setting that will stop these video popups from automatically launching? They eat up a lot of memory, and are a pain to turn off manually.

Thanks.

since firefox 133.0.3 i can no longer use video controls in youtube. youtube video controls (scrolling an sound volume) work when youtube is in firefox picture in picture mode. when picture in picture is disabled in firefox settings youtube controls still not work.

thx for forcing me to use a feature i do not want. pls fix this.

Starting early this morning I could not open a website (where I purchase supplements) I have accessed in the recent past. I added the address to the DNS listing but that didn't help. In the verification lock icon in front of the address it says the connection is secure. But below it states the Connection verified by a certificate issuer that is not recognized by Mozilla. Prior to 1/22/25, I had no issues opening this or other websites. It doesn't matter if I have my VPN turned off or not, the website does not open. Was the Mozilla update of 1/22 the cause? If so, how do I rectify the issue I currently have? If not, how do I rectify the issue I have?

I'm tired of trying to find a solution to this problem, you're deaf!

I have been using Firefox since 2003. to avoid writing unnecessary words, I will simply state, I will leave firefox if you do not eliminate this problem:

firefox eats up all the RAM on my Mac. It is none of your business whether I open 1 tab or 10 tabs, give me the ability to limit the memory used by firefox, otherwise it eats up all the computer's memory.

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.

I get bills in PDF form from my water and gas provider. When I pay the bills I use Adobe to add a "PAID" sticker and a comment indicating when the bill was paid, and then I save the PDF (from Adobe) with the newly added comment. Previously I was able to open these PDFs in Firefox and the contents of the comment (added via Adobe) was visible; however, recently when I used Adobe to add a comment to a PDF and then opened it in Firefox the contents of the comment were not displayed (NOTE: I opened the PDF in Edge and it displays the contents of the comment, but it doesn't display with the same wrapping as used when the comment was created in Adobe). Interestingly, older PDFs that I added comments to still open correctly in Firefox i.e. they display the contents of the comment. I am assuming there has been some sort of update to Adobe, and was wondering if there needs to be an update to Firefox to continue to allow the contents of comments in the PDF to be displayed.

Hi, Nvidia RTX Video HDR and Super Resolution works fine when I open a link. But if I scroll the page it turn off. The video still play but the colors changes, I can see that RTX enhencement is then inactive on the nvidia panel. Sometime immediately sometimes after more scrolling. Same on Youtube and Twitch. Any Idea ?

Using: Firefox v132.0.2 (64-bit) for Linux (Arch Linux)

Picture-in-Picture (built-in) not working correctly. Consider attached image e.g., the video is visible, but I can't really use the any of the other tabs visible here. What I noted: I can scroll the other tab/window using mouse wheel when the Picture-in-Picture is in focus, but as soon as I click on any of the other tabs/window, the video goes to background, and hence becomes "invisible".

Dear Community!

i have Linux Cinnamon 22 and want to stop the PIP on YT. I disabled/unchecked box for PIP on FFox and PIP still happen on YT. What can i do to stop this horrible PIP now ? thank you.

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?

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,

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!

I asked this a year ago and never saw a solution (other than 'gee, it should work yet'.) 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? Attached is what I see on each attempt.

I tried various settings for DOH and nothing works. I can reference the Hosts file in a Windows Cmd Prompt and it resolves just fine. Something is screwy in Firefox for some time now and I'd like to know what.

I have cleared cashe, history, Turn VPN off, Turn adblocker off, these were all on when it worked. Now nothing

This question relates to version 134.0.2 (64-bit). This morning I started Firefox and found that many of my bookmarks were missing. On trying to restore from the program automatic backups, I get the repeated message "Unable to process the backup file." On examination, the files, while not in ASCII, appear to contain ASCII text strings recognizable from the bookmark descriptions. They are not, at least, empty. Unfortunately, I do not have an HTML format backup. Any idea why none of the backups work or what options I have? Thanks in advance.

Firefox will not longer close without also closing my pinned tabs which pretty much defeats the purpose of pinning tabs for later and makes it much harder to keep track of things. I didn't notice the first time and lost my pinned tabs that had been there for months, I immediately put them back but now everytime I try exiting firefox it informs me i'm about to close however many tabs are open + the pinned tabs. Does anyone know how to solve the problem/what might be causing it.

Every time I try to view a pdf file on Firefox I can view the file but in the lower right 1/4 of the screen I get a graphic of a page with shaded areas representing lines with writing on them. There is a type of pen cursor moving along the line.

This happens with different pdfs - from the internet and from my saved files. This doesn't happen on another computer with Firefox.

I've deleted and redownloaded Firefox an number of times, also tried troubleshoot mode - no improvement. Virus scanned, restarted a number of times.

Pdfs work on edge and chrome and reader with no problem.

I have a screenshot.

Any Ideas? Thanks
