A certain set of plaintext files are rendered in a weird way when opened in Firefox.

Some plaintext files are rendered "MS Gothic", which is the default monospace font for plaintext files in Japanese encoding. (Also, if I change font.name-list.monospace.ja to "monospace", the font changes).

However, the files are not in Japanese encoding, they do not contain a single character in Japanese encoding. Since the files are local, they have no HTTP headers to determine the encoding, so Firefox must have guessed the encoding somehow. How can I stop firefox from detecting those files as Japanese while they are not?

Also, I noticed that this issue happens only with long files. The shorter a file, the less likely it is that Firefox renders the file as if it had Japanese encoding.

Since I cannot reproduce the issue with smaller files and the files contain confidential information, I am unable to provide a minimal reproducer.

As a workaround, I could change font.name-list.monospace.ja, but this would change (potentially break) rendering of Japanese websites.

I'm using Firefox 124.0.1 on Windows 10, although this issue has been present for at least some months (at least 4 firefox releases).

The screenshot shows an excerpt where the text "C:\Temp\2024-" is partially rendered with Japanese glyphs and fully rendered with "MS Gothic" font which is hard to read with ASCII characters.

I want my websites content to be remove in reader mode in firefox how i can acheive this.

I am a developer and i am using one div in which i have content and images in that i dont want to fetch them in reader mode.

I am experiencing more and more pages suddenly not working on numerous websites. I am working with an Imac running OS 10.9.5. I am experiencing problems with Firefox, Chrome and Safari and am having to revert to my Microsoft Lap top for a working browser.

Any ideas on this???

Hello,

I use Firefox stable on both my Mac and my Win 11 PC. On the mac i use the developer edition. The issue I have started about 2-3 weeks ago. Most of the time, playing youtube 4k videos just either freezes and doesn't buffer, or just skips and reloads. It is not a network issue. I've tried playing back the same video with ARC on OSX (which is based on chromium) and with Chome on windows. It works flawlessly so it's not a network issue. I've tried disabling adblocker, all the extensions, nothing. It's either Youtube messing with non google products again or a problem with Firefox itself. I even have Youtube premium and this stuff still happens without adblockers.

Any help would be appreciated.

Hello, I'm using a document management system (SeedDMS for those who know) through Firefox 122.0.1 (64-bit, canonical 1.0, downloaded from packages.ubuntu.com for focal, running on Debian Bookworm, kernel 6.1.0-17-amd64/Debian 6.1.69-1 x86_64, X.Org X Server 1.21.1.7, KDE Plasma 5.27.5, KDE Framework 5.103.0, QT 5.15.8, i7-5820K, GeForce GTX 1070).

Within this document management system pdf.js (v4.0.379) is being used to preview/view PDF Documents. After starting Firefox the PDF view inside the DMS works fine until I suspend (to memory) and resume my machine. Regular HTML-content looks fine but the resumed DMS session shows only blank (all white) Pages inside the PDF view. Changing to a different PDF file doesn't help. The number and size of these pages is presented correctly. I can even select and copy (invisible) text from these blank PDF pages. The problem applies to all PDFs, whether they're single or multi paged, have images inside them (like with PDFs from a scanner) or not, etc. Reloading the page/closing reopening the affected browser window doesn't help, i.e. the problem persists.

I recently found out, that this also applies to PDF files directly opened inside Firefox (which also seems to use pdf.js as a PDF viewer), that is, this is not related to a specific site like my DMS.

The problem always persists until I kill Firefox and start it over.

Pdf.js seems to use a canvas inside a div (see screenshots attached) to draw the visual PDF content and another div to make the text layer selectable/searchable etc. I don't know what's happening to canvases on a system suspend/resume cycle in Firefox on Linux, but I suspect that's where the problem originates from.

This problem already affected older versions of Firefox and pdf.js.

Please let me know, if you need further information from my side to investigate that issue.

Thanks a lot!

Since your last update I can no longer view my credit card statements, it downloads a pdf file. If I go to download the pdf instead I receive four pdf files downloaded. The edge and brave browsers don't do this.

When I am watching a video from inside firefox, I am unable to exit full screen mode by using the esc key. It was working before and after updating firefox it suddenly stopped.

Please assist

One part of the article I read says the connection issue is due to HTTP, another part of the Article says it is Googles fault due to their HSTS security policy. I have to say Poppycock. I can successfully login to my Gmail on my tablet I just cannot connect to it with my laptop. Firefox itself is refusing to allow the connection. Unfortunately it happens more often than you'd expect. I am in no way or by any means capable of computer repair, but I seem to enjoy tormenting myself with constantly taking apart and rebuildingthis laptop, Took me almost 3 months to finally find out how to stop Firefox address URL bar from highjacking the search bar with that really annoying awesomebar in about:config. But something just seems wrong with the browser on the laptop not being able to connect, but there is no issue with the tablet.

Thank you for any advice or solution that could help me with this. Ive thought about the firefox refresh reset option instead of uninstall reinstall, but if there is a better solution

When I try to Forward a gmail post with either a CC: or BCC: Command, my Contacts List doesn't load. Initially, I see an "X" in the right-hand corner

followed in less than a second, by another "X" superimposed over the first one. What might be causing this? I (reluctantly) loaded Google Chrome and made it

my default browser, after which, my Gmail worked properly. Assuming, then, that the problem is being caused by the Firefox connection to the Google servers,

I uninstalled Chrome with the Revo Uninstaller Pro and reviewed the Firefox settings.

My Firefox Extensions are thus: AdBlocker for YouTube, Disable HTML5 Autoplay, DuckDuckGo Maps, DuckDuckGo Privacy Essentials, Enhancer for YouTube,

ExpressVPN, HTTPS Everywhere, LastPass, Malwarebytes, Online PDF Editor, Pinned Google Calendar, Return YouTube Dislike, SponsorBlock for YouTube, Video

DownloadHelper, and YouTube High Definition.

Hi all. I am having a strange issue with Discord. I can get notification sounds and all other media plays fine there. But whenever I try to "speak comment" or set the settings to always speak comments, nothing happens. The tab shows "playing", but no audio comes out, and nothing shows coming through on the mixer.

Chrome does speak as expected. A different computer, same version of Firefox also does speak as expected (in a different voice though). So that narrows it down to something in this particular copy of Firefox that is causing the problem. Plugins, settings and extensions on the two computers look the same. Also tried a different audio interface. If anyone has any ideas, please let me know!

I am unable to log onto easy jet in firefox, the site freezes. when i use opera i have had no problems. this has occurred since your last update. Can you help? Alan

bold textWhen I log onto Firefox I get this message. "This site is blocked because it may contain unsafe content that can harm your device or compromise your personal info.

The Washington Post has a feature on some articles called "Listen", where the article is read aloud on the device audio. I often use this because my vision is not as good as it used to be, and I can listen while I perform other tasks (e.g., cook). There is an example at this URL: https://www.washingtonpost.com/opinions/2022/05/24/trump-picks-primaries-perdue-lose-dangerous/

Click "Listen" just above the first text of the article.

This is FF 100.0.2 on Windows 10 21H2 build 19044.1706

I do use the Malwarebytes add-on, but it doesn't work even when I disable it and the FF tracking protection is turned off.

It does work in both Edge and Chrome, with Malwarebytes enabled.

This is very disappointing ...

Hello Team,

gmail page initially loads in firefox and then doesn't get updated at all. Upon trying to refresh it just gets stuck at Google workspace initialization section. After that under new tab, google.com also doesn't work. Please fix this.
