Since mid-December, I've been experiencing abnormal lag on the https://namu.wiki website when using the official build of Firefox. For example, there's stuttering during page loading, and when I hover the mouse cursor over a hyperlink, there's about a 3-second delay before it responds.

However, I found that the site works correctly when using the Nightly build of Firefox. I suspect that this issue is not related to any extensions.

According to the page https://namu.wiki/w/Firefox#s-4.1.1 similar issues have occurred in the past with the official Firefox builds.

Please help.

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.

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".

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 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!

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.

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.

Firefox 134.0.1 videos keep popping up in new window automatically without user control

When I watch Youtube and I go to another tab the video keeps popping out a new window and when I go back to the youtube page the pop-up video collapses to the original window in Youtube. The same problem occurs in Rumble voideos so it has to do with Mozilla-Firefox browser & not the video sites. This behavior where the user has no control on "WHEN A VIDEO SHOULD POP-UP" on a separate window only has happened under the latest Firefox version. I don't have any Extension Add-on that may produce this behavior. It seems that the Settings only turn off completely pop-up videos If this is not solved I will definitely switch browsers. The user no longer has full control when a video should pop-up in a separate window. This should be a feature fully controlled by the user and not automatically by the browser. It is EXTREMELY ANNOYING. I've tried different settings suggested by other firefox users using the About:Config settings but none have worked. This is a major bug or a depracation of functionality. Please advice.

Thank You EM

Hi & Happy New Year,

OS: Windows 11 Graphics Card: NVIDIA GeForce RTX 3080 Display: LG 27GN950 Firefox: 133.0.3 (64-bit)

When I wake my monitor from power save mode Firefox has shrunk in size. I usually have my Firefox window sized at something like 2200 x 1900 pixels. Whenever the monitor wakes from power save mode the window has been resized to 1011 x 712.

Any suggestions for troubleshooting?

Thanks.

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've had FF for years and never had a problem. In the last week, when i read an email with a link (and other links), it says Hmm. We’re having trouble finding that site.

We can’t connect to the server at clicks.aweber.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

As far as I know, I have not changed anything in settings. I'm looking for some resolution on how to fix this. Thanks.
