Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

This started a week or two ago intermittantly on some websites. Today I cannot see any images of amazon items in the shopping cart. I can see the thumbnails in the right side bar, and if I click on an item, the image appears on its for sale page. Ebay usually shows the first image, but the rest won't load, unless I click on "unable to load images" and then they might. Or if I use the icon to put the images in their own box, I can < and > to navigate them

Turned the new "secure DNS" feature off & on, no difference. Turned off NoScript, no difference.

I have used Firefox for longer than I care to remember and have never had any problem with it but this morning I switched on my PC and a new AI side bar has appeard on the left and I don't want it. Can you please make it so we can remove it and looking around the internet, I know I'm not the only one with this opinion.

Messages I send do not show up in Sent folder in Thunderbird on Windows 10.

The emails do arrive to their destination email but do not show in Sent folder.

Is this a bug or is there a setting that needs to be changed to fix this?

When attempting to sign in using google on firefox, the page I've included as an image below pops up. In order to solve the issue, I've tried clearing cookies and browsing data, refreshed firefox, and uninstalled and then reinstalled firefox. This happens on all websites, and only when using firefox.

Why do I have to re-register with my banking website to remember my settings in order to not need two-factor authentication? I have selected in Preferences/settings for that website's cookies, etc, to be retained in Firefox.

i'm on windows. Suddenly, PDF files that I open have black pages. I checked that the default setting is to open pdf files in Firefox, as always. refreshing doesnt work. Any ideas what is wrong?

Your ads are all over my computer even in programs that are not yours. This is very intrusive and annoying. No one is going to look at these and one has to get rid of them to continue using other programs.

How do I stop these ads from coming on my computer?

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

I recently got seriously worried when I became aware about the new AI firewalls these days, which monitors or inspect SSL encrypted packets, before the packets reach to the main website. These new AI firewall systems are installed in some countries by their governments to suppress free speech, or just spy on its people. These firewalls, as you may already know, uses DPI-SSL system, which decrypts packets traveling from user to the main website. To decrypt the HTTPS packets, these firewalls uses its own self signed CA certificates. So I am asking the firefox developers, that why you guys allow this privacy issue? Does the packets sent from a firefoxe browser to other websites are also decrypted, by these firewalls? If yes, then why you guys allow this? Firefox must ONLY allow a specific CA certificate made for firefox browser only. Firefox browser must never let other third party softwares, or any software, to decrypt its encrypted packets. This is a serious privacy issue. With these firewalls, they can see what users write in chats, or posts, they can see witch content we are watching on a website, they can see who we follow on social media platforms, they can see which content or posts we like and etc. Even passwords are not safe anymore, which e use for any website of platform. When passwords are not safe, so does our accounts of various websites. This is a serious privacy breach.

These firewalls is a weapon for those countries which want to suppress free speech or suppress opposition sides in a government or spy on its own people.

Please let me know if I am mistaken or my concerns are genuine.

No videos on any platform will play when I try to open them in Firefox. They are forever stuck on the thumbnail image of the video, and nothing happens when I hit play. I've had this happen a couple times and was able to resolve before by installing updates and uninstalling my Mozilla VPN, but this time nothing has worked. I've tried pretty much every solution I could find online:

• Updating Firefox
• Updating my computer
• Running in Incognito
• Running in troubleshooting mode
• Allowing autoplay
• Disabling hardware acceleration
• Disabling addons
• Clearing cache and data
• Enabling/disabling DRM content
• Installing Windows Media Pack

I'm running Windows 10, and videos seem to work fine in Edge, if that makes any difference.

I am writing to request assistance with recovering my deleted browsing history for my Firefox account. On June 18, 2024, I accidentally deleted my browsing history and I am hoping there is a way to restore it.
