Firefox Support Forum

A new version of Firefox was installed yesterday and now my Adblocker Ultimate is blocking content on some sites. For example, I can no longer see my local digital newspaper and photos on the Eddie Bauer website no longer load. If I turn adblocker off, the website loads correctly. These sites, and others, have worked fine for years. How can I fix this without turning adblocker off?

I have installed Firefox on my new computer but some bookmarks did not transfer from my old computer. This includes those bookmarks shich displayed on my old computer only when I clicked on "search bookmarks." When I click "search bookmarks" on the new computer, it only displays bookmarks I have visited on the new computer. New computer is running Windows 11. How do I transfer these bookmarks to my new computer? Thank you.

I got an error message when playing a movie that said clear cookies & cache so I did that. The movie played after I did that. Now today I opened a weather link and when I clicked on precipitation it didn't work. I clicked on a One Tab link to youtube and it opened youtube home page, not the specific link with all my history and feed lost. And some youtube videos would not play. I tried to open my Outlook email from one tab, but I just got outlook and had to re-sign in. And then I could not open an email. I had to switch to chrome to open the email. I tried to use trouble shoot safe mode. I was able to play a youtube video, but my extensions were then unavailable in safe mode, so no one tab. I am 75 and not very computer proficient, and I am afraid I will make things worse because I cannot predict the outcome of the steps offered. Mozilla/Firefox updates automatically, so I have the latest version of that and I have macOS Catilina version 10.15.5 Is there anyway to undo this mess? I need help at the most basic possible level. Can the clear cookies & cache be undone? Is my youtube history & feed able to be restored some how? Help please!!!

I'm using Firefox 116.0.1 on Ubuntu linux. I'm not using a VPN, antivirus, a proxy or any kind of http filtering.

When attempting to load a certain website I get the message: "An error occurred during a connection to www.[website].org. PR_END_OF_FILE_ERROR"

Google results tells me that firefox throws this error when it can't resolve a safe SSL/TLS connection to the website.

The thing is, I don't care. I'm aware of the risks of browsing on a website with outdated or non-existent certs.

How do I get firefox to drop this security measure?

Before I can even get on my computer, I can see Notifications for Firefox. I use my password to login to my desktop computer and the Notification in the upper right hand corner are there for a few seconds more, then they disappear. I do NOT know where to see them again and I truly would like for this activity to stop. Where do I find Notifications after I launch Firefox (my preferred browser and the ONLY browser I use) to see what the notifications have to say, and how can I disable Notifications?

Since uploading the latest update today many of my webpages no longer appear properly. I have given you an example of one which has the URL of https://www.newsnow.co.uk/h/Sport/Football/Premier+League/Tottenham+Hotspur?type=ts You can see from the screenshot image that is added to this message what I mean. This is happening on quite a few websites now. Can you please advise a remedy or address the problem ?

When I pick on bookmarks at the top left and it drops down there is recent tags and recently bookmarked, this is on laptop 1 with windows 10. When I am on my newest laptop windows 11, I do not see the recent tags and recently bookmarked. Is this something under settings?

not talking about settings smooth scroll. I have it disabled. but with the new update when clicking in the scrollbar, it has smooth animation and scrolls 10 times slower. fix it.

Just updated my firefox browseron my windows laptop and lost my sync to my iphone 12. I followed the directions to set it up but my iphone does not have "sync and save data" in the menu of the IOS firefox app. Any advice?

I've opened a video in Full-Screen on my 2nd Display. I know it's in Full-Screen. I am watching this in Full-Screen on my 2nd Display. I do stuff on my 1st Display and i am watching a video on my 2nd Display in Full-Screen at the same time. When i switch back to 2nd Display (click with my mouse on the video which is running in Full Screen), a warning message will pop up that i am watching a video in Full-Screen. YOU DON'T SAY!

I made changes in my config full-screen-api.warning.timeout = 0 full-screen-api.warning.delay = 0 full-screen-api.transition.timeout = 0 full-screen-api.transition-duration.leave = 0 full-screen-api.transition-duration.enter = 0

It's working until i leave my mouse pointer on my 1st display and click on the Full-Screen video on my 2nd display with the Full-Screen video which is running in Full-Screen on my 2nd display in Full-Screen because wanted in Full-Screen on my 2nd display.

If you answer is cause of security reasons, i saw this JOKE Phishing attack example on https://feross.org/html5-fullscreen-api-attack/ So explain me why "full-screen-api.mouse-event-allow-left-button-only" is set to True?

I know many People are mentally challenged but do not punish us. So tell me how can i remove this Full screen Message warning entirely.

Thank you.

A video I am watching is in 4:3 aspect ratio and comes with black bars in the embedded player; however, when i enter fullscreen (on a 16:9 display) the video stretches horizontally, getting rid of the black bars, resulting in a bottom portion of the video being cut off. This happens on my macbook pro running firefox 116.0.1 that is connected to a television monitor. This issue does not happen on my desktop monitor of 16:9 resolution. For about one second or so when the video first enters into fullscreen, the video is played how I want it to be played (non stretched, 4:3 aspect ratio, with vertical black bars on the sides), but then it auto adjusts itself and switches to a stretched resolution, which is what I DO NOT want. In case this info is important: When I exit the video, the entire screen is in a stretched resolution for only about a second until it then adjusts itself again to return to a normal display view. I am in dire need of help, it's driving me crazy.

(similar to this thread: https://support.mozilla.org/en-US/questions/1401072 , except my problem occurs on a non youtube site, so im not sure how the tags solution would work)

We have a website we are using for supply chain. When we look at orders it shows up in PDF for printing. While using FireFox after a few PDF's they are starting to show corrupted data. Even after deleting cookies and Cashed data

I downloaded a app on my Macos Big Sur workstation (https://kevin-de-koninck.github.io/Clean-Me/) and I ran it (I did not have the option "User Preferences" Selected) Somehow, after rebooting my computer shortly after, it had logged me out of my Firefox account. That shouldn't be a big deal right? Somehow at the same time my Lastpass password program does not have that account saved in it. It has a secondary account ( that used to be the primary, but I guess I switched it at some point) that I can login to, however whenever I login to it, it says

I've been having issues with Firefox since the latest update. Currently using Windows 11 on Lenovo compact PC.

I cannot load any Google related website and some other specific websites, including Instagram, Airtasker and Youtube. All documents on Google drive are inaccessible, Gmail cannot be opened and Instagram is only showing feed from yesterday. Google Maps appears to be working fine but I'm not sure if this is just luck. It seems all saved content (via cookies?) are normal, but I cannot get any real time update.

I've tried removing cookies for Google related website but it does not work. Have also reboot and restarted several times. I would want to avoid reinstalling Firefox as it's time consuming and I might lost all my saved logins.

Since logging onto Firefox this morning, I began getting a message that say Passkey error due to a server error (??). Reading further, I am asked to get a # code from my email, insert it in the query box, and submit. When this does ANYthing, it shows the Amazon site all run together with type that's too large and huge item icons.

I have been able to successfully log into Microsoft Edge to access my Amazon account where it displays normally.

I hate to use other Browsers. Can you help me get back to normal on Firefox?
