Firefox Support Forum

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!!!

Firefox 115.3 kept crashing on opening. I tried Safe Mode, but that also just crashed straight away. I'm not aware of any changes that have been made that might trigger this. I've not changed any settings, or Add-Ons, or anything like that.

Even though I was supposed to be getting the latest updates, I was not informed of 116. So I have now downloaded and installed 116, and everything has disappeared. Bookmarks and settings, all gone.

I know they still exist, cos I can see them in Firefox 112 on my laptop. But on my desktop, it's like a virgin installation.

Help!!!!! Thanks for reading.

[Mac OS 13.0 Ventura]

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.

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.

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?

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'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?

I got the notification that there was an update available...clicked on about Firefox and it is trying to download a new browser at 90mb...why is this and how do I get it to stop???

I'd like to know what encryption algothim is used for the password manager and the process behind it. Since I'm using this information for a paper I'd appreciate it if you could add a source as well if possible.

Why is firefox that set as my default browser having an issue of with my keyboard key strokes? When I type out a letter key, it shows it in a different key alphabet? For example, if I type “a” on the keyboard is will show a complete different random key like “5” or “d”. I am very comfortable and love using your browser. And would want to continue doing so without changing to another.

- A practical example is the following attached screenshot. I have typed the word “qwerty” on your browser but instead I get displayed on your browser “dfghjk”. - Very important to know is that I am running “ZoneAlarm Extreme Security NextGen” Anti-keylogger. That is configured to block programs that secretly record keystrokes (see attached document). Why is it only Firefox that is affected by this? - I have also contacted Zonealarm and they instructed me to contact you about this seeing that this issue only happens with your browser and not with any other program. I can type in Word or outlook or any other App without issues. ( - Like you can see from my other attached screenshots, it is not only your browser (firefox) that I have installed and working with as my default browser that is the only one having issues. The other browsers (Google Chrome, Microsoft Edge and Brave) are all working perfectly without this issue/problem. But only your browser that I made as the default browser that is the only one having this problem. - A good example, I typed this whole message using outlook without an issue/problem of this sort (see attached document).

Can you please look into this and provide me with answers on how to resolve this.

I was trying to set up Mullvad but upon reaching the settings where "DNS over HTTPS" once was I noticed it was gone, how can I change provider now without the option too?

I ran a program on my mac (https://kevin-de-koninck.github.io/Clean-Me/) without the "User Preferences" option and it still signed me out of my Firefox account .Usually shouldn't be a big deal but somehow my Lastpass account doesn't have the password saved (which I use to login to getpocket.com every day, so I literally don't understand what is going on with it not being in there) so I can't login to it. It's the main account, and I can login to my other accounts attached to it, but I get the error "login with main account" after I sign in successfully.

So, I can't login to my main account (main@example.com) but I can login to my attached account (not_main@example.com). Also, on my phone i am logged into main@example.com, but I can't change the password without knowing the password. And if I change the password to main@example.com it will reset my account which I really don't want as I have years and years of bookmarks and history on there.

Can anyone help? Please, and thanks in advance.

Firefox keyboard recognition not working. The letters that I type are not those appearing on screen. I’m typing in Word, & copy/paste in order to write the text.

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
