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

I have change my home page to DuckDuckGo, but when I click on a new tab, "+" I get Firefox. I tried blank and it is indeed blank, so how do I set new tab so it opens DuckDuckGo? (Read all help articles.)

Hello,

I recently updated my Firefox browser to the latest version, 138.0.1 (64-bit), on Windows.

After the update, I noticed that when playing videos in fullscreen mode (for example, on YouTube or other video websites), the Windows taskbar (the bar at the bottom of the screen with the Start menu icon) does not hide automatically. This is affecting my fullscreen viewing experience.

Before updating to version 138.0.1, the Windows taskbar would hide correctly when entering fullscreen video.

I was wondering if anyone else has encountered a similar issue with the Windows taskbar not hiding, or if there are any suggested solutions to help resolve this problem.

Thank you for your help!

When I go to view an already open tab it will sometimes randomly move it to the very end of my tabs all the way to the right. I don't want it to move tabs without my intervention. Clicking on a tab should keep it in place.

This has been an issue for about 2 months now. I'm not sure what's causing it or even if it's entirely a Firefox issue as I have noticed something similar happen in another program with tabs that I use often. It still seems like a Firefox issue in that moving a tab all the way to the end is a very specific task that can't normally be done accidentally.

Is there a way to prevent this from happening or has anyone figured it out?

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"?

Bonjour, je voudrais exporter mes liens Pocket, mais je n'ai pas le bouton Exporter le fichier csv. Et quand je clique sur le bouton Export de la page de Pocket, il y a un message qui dit que cette page ne sert a rien(voir fichier joint) . comment puis je faire? Merci d'avance de vos réponses.

I asked for an export of my saved pocket articles and when I click on the link sent I get this:

My Win10 & Win11 pc's updated to this version and they all have the same problem: The bookmarks have disappeared. Including my pinned bookmarks on FF's opening page.

I also just noticed that there are no "toolbar items".

Since your last upgrade, I have been able to get into any sites using CloudFlare security. Prior to that I had no problems at all. I have tried closing extensions and or clearing cookies. I especially want access to my banking account. How can I disable whatever was added to effect CloudFlare? CloudFlare either continues to cycle, or gives an error message.

I need to enlarge the font on the bookmarks toolbar as I have a visual impairment. I can find ideas for the regular toolbar, but not for the bookmarks toolbar...oh, and I am working on a Mac.

Thanks in advance for any help.

I'm having some trouble with automatic translations on firefox. I don't know if It's exclusive of firefox, but some websites, mostly wikis, open a "translate" field that automatically creates a new website, wich causes the images and some other stuff on the website to break. I tried disabling the translation on about:config off, as show in some other questions, but it did not work. This is being really annoying because it keeps breaking websites unless i get to the original link.

I have a windows 10 computer with Fire Fox and lots of bookmarks. I bought a new windows 11 computer and want to copy my bookmarks to the new windows 11 computer. How do I do it?

Mailfence.com is my email provider. I've been with them for years. Two weeks ago I am suddenly unable to connect with the website. My ISP is Comcast. My next door neighbor also uses Comcast. He can get to mailfence.com just fine. Can you please help with this issue. Comcast has declined to provide any help. Thanks.........Bob Horning

I am still using Win 7 but converting to Win 11. The most recent "patch Tuesday" update from MS killed Office 2016. Since then Fire Fox will occasionally pop up the "Couldn't load XPCOM." (no file extension) warning. It may do this when opened but not always. Can also occur in the midst of a session.

Program seems to be working correctly but some of my pinned locations disappeared when this started. New locations are retained between sessions. Is there a problem with continued operation with this warning? Is there something that I can do to repair it.
