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 cannot get past the secure connection failed! I have cleared cookies, cache, etc. I have turned off the firewall, and restarted my computer more times that I can count....

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.)

I believe there was a button to send a url link by email on Firefox. I tried to find that button everywhere, but I still can't find it and it didn't even get to an answer for this by asking questions on Mozilla website. Could you kindly guide me where to find that button?

Thank you in advance.

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!

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.

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?

I took a look today and I had 237 MB in cookies! This was after clearing the cache of all files. I've only had this (new) machine a couple months.

Short version: Sites have "cookies" from 200kb to as much as 34MB! For many of the sites over 3MB I have no account and have visited them only briefly.

To be clear, I don't care about the space being used. It's trivial. But what the heck is FFox storing and calling it "cookies"? Last I checked, a site was still limited to 4K size cookies and perhaps 50 per domain. So how are we getting to MB+ sized "cookies" per site? Again, the cache was cleared, so what's left aside from trivial cookie files of <4KB?

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"?

Hi,

I have sent an email to support but didn't receive an answer yet, so I hope someone here might be able to help me.

So I've been trying to export my Pocket list, but didn't receive any my email.

After going over few of the support articles. I've noticed that my email didn't show up in the settings of Pocket. I have updated the email address, but I am not receiving the confirmation email.

I've tried 3 different email address.

Any idea what can I do? Thanks!

I just update firefox but all my none of my bookmarks loaded. I share my computer with my husband. He has a different account on this same computer and his bookmarks are showing up on my side, but mine are nowhere to be found. Previously we have had separate bookmark lists and all was fine. I don't know where my bookmarks went.

How do I get them back and put on "my side" and still have my husband's on his side?

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:
