Dear Firefox Support Team,

I am encountering an issue where PDF files fail to display properly in Firefox, appearing as blank pages. This problem persists across multiple PDF documents, suggesting a potential browser compatibility or configuration issue.

Request:

   Please investigate this behavior to identify the root cause (e.g., rendering engine, plugin settings, or recent updates).

   Adjust Firefox’s default PDF handling settings or implement necessary fixes to ensure proper PDF display.

Additional Details:

   Firefox Version: All
   OS: windows&mac
   File link: https://res.mdpi.com/data/pharmaceuticals-18-00847-v4.pdf
   Steps to Reproduce: Open any PDF file → Blank page appears.

This issue impacts productivity and user experience. Kindly prioritize resolving it or provide workarounds. Thank you for your attention.

Best regards, Mia Yu meijuan.yu@mdpi.com/1036926860@qq.com

So, my problem is with HW acceleration in FF. Basically:

If its enabled: It causes graphical artifacts in videos [See screenshot]. If its disabled: It brings screen tear in to videos and autoscroll [Like if Vsync is disabled in games].

I tried safe mode, I tried reinstall of FF, I tried disabling and enabling extensions. I tried to set Vsync on in Nvidia control panel... the only thing that impact those bugs is HW acceleration in FF.

My drivers are up to date, my browser is up to date, yet there is such trouble.

Any ideas or solutions?

Hello, using Windows Version 22H2 (Build 19045.5965), Firefox 139.0.4, Thunderbird 139.0.2, I can drag multiple emails from Thunderbird but not drop them into Firefox (the stop symbol appears and does not let me finish the action). However, dragging and dropping single emails does work. Firefox does not understand the imap address but the drop is registered which is all that is relevant to me. Is this a bug/missing feature in Firefox or a problem with Thunderbird and Firefox on Windows? Or is there a way to do it by simply adjusting (preferrably very few) settings? Dragging and dropping multiple emails using Thunderbird and Firefox on Linux Mint works fine. Dragging and dropping multiple emails from the Windows Explorer to Firefox also works fine. In testing, the issue only arose using Thunderbird + Firefox, Chromium-based browsers also worked fine with Thunderbird. If this is the wrong forum to ask such a question because this should rather be in a bug tracker or something similar, please let me know. If this should be on the Thunderbird thread instead of Firefox, also let me know. Thank you for your help.

We can't get into our gmail (3 accounts ) on 1 pc , but we can use a friends pc both using a firefox /windows v-11

People don't respond to Gmail requests, only computers with simple answers for simple inquires, HARD THINGS ARE TOO HARD FOR THEIR MAINFRAMES. THANKS

I have only one instance of Firefox to run.

How can I correct my installation so it does not think something else is running/updating Firefox?

Thanks,

Craig

I realize this is in a beta OS, but I imagine it'll need to be addressed at some point.

Anywho, when using vertical tabs, the left side expand/collapse button lives underneath the close, minimize, full-screen OS buttons.

If I turn on "always use private surfing", can I not have shortcuts on my Firefox landing page?

I had six shortcuts on my landing page; however, I turned on "always be incognito", and my shortcuts disappeared, and I do not see an option to add them back.

Are they mutually exclusive? If not, how do I FIX THIS?

I have three computers on a home network. All 3 have Firefox on Windows 11 Bookmarks on Two are in sync. The third will not. When I login it has my email and password but creates a new profile.

Every time the browser autofills a password it asks me for my Windows password. I don't want this behavior, as this makes password autofill completely pointless. How do I disable this "feature"?

I'm using Firefox-bin on Gentoo, wayland, and for a long time with all updates on my main firefox profile smooth scrolling can not be disabled: Both UI settings called "Use smooth scrolling" and manually setting general.smoothScroll on false - does nothing. Setting general.smoothScroll.mouseWheel on false actually disables smooth scrolling for mouse wheel, but smooth scrolling still happens on keyboard scrolling (holding up or down arrows).

On same browser I have two different profiles: On one of them smooth scrolling were disabled long ago On another one I successfully disabled smooth scrolling this day (it's some default one that I haven't used)

There are no extensions that could override this and I tried disabling them and rebooting and trying again too. I haven't touched any other scrolling relating options except enabled "autoscroll" and tried disabling apz.gtk.kinetic_scroll.enabled but it made no difference.

I found only few entries that describes same thing from long ago but they seem to not be applicable to this one. This bug is only mildly annoying because I rarely use keyboard scrolling and general.smoothScroll.mouseWheel = false already solved half of issue but I'm worried a little if something is wrong

I have not changed any settings related to fonts in firefox (running on windows 10 desktop), but I have this issue where flag emojis are displayed as a letter code on the page itself, but still display correctly in the tab at the top. is there a known fix for this?
