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 [email removed]@mdpi.com/[email hidden]@qq.com

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!

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!

Dear all,

I just found that in Firefox 139 for Android the menu buttons "Install" and "Add to Home Screen" disappeared. I tried deleting the cache, reinstalling, restarting the smartphone. I tried different websites, included well-known PWA apps (i.e. https://github.com/mdn/pwa-examples ).

I'm on Lineage 22.2.

The community guides still report the availability of this feature: https://mzl.la/3p7ltJx

Am I missing something?

Example with facebook.com in the images. Note that on x.com a popup asks me if I want to installa the app version of the website, but the menu options are still missing. It's only website I found where that popup shows up.

I read the The Times in the UK and have no problem viewing on my iPad and Google Pixel phone using the Firefox browser. However on my laptop using Firefox I get a screen that says Secure connection failed and recommends contacting the vendor as there is no workaround. On microsoft Edge there is no problem I like Firefox but for me this is a major limitation. Any ideas or suggestions welcome

Not all the time but getting more frequent

Any ideas

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.

firefox keeps knocking me out of certain web sites such as discovery netflix ,telling me to update to the latest version then restart it but no luck so far please help me ,as i still getting payed for the webpages but still can not watch because i need latestversion of firefox please 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.

Mac OS Sequoia 15.5 Firefox 138.04

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?
