Firefox supportforum

I tried clearing cache and temp files. I tried a new profile. I tried a fresh install without logging in on account. Tried disabling all addons, running in safemode and incognito. Nothing works.

When opening in Chrome, it works as always. Same computer.

I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

When trying to open my protected browser with firefox I keep getting "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." I have refreshed and re-installed Twice! I have followed the instructions to go to file (using %APPDATA%\Mozilla\Firefox\Profiles\) and make sure it is NOT Read-Only and to delete the parent.lock in it. Yet it keeps going to Read-Only and the parent.lock keeps re-appearing. The day before everything was working. I have tried Protective Browser with other browsers and it works. 1. Why is the Protective Browser not working? 2. Why is the File going to Read-Only and 3. Why is the parent.lock keep returning? Thanks

All of a sudden I can't open a certain website. I opened the website a few days ago with no problem and have been using the site for years. (I checked to see if the site is down but it's not.) I googled how to unblock websites in Firefox and nothing I've tried works. I disabled Trackers for the website and I cleared my Cookies. I added the Firefox uBlock extension a few weeks ago to stop constant website popups (after I tried resetting Firefox) and I turned uBlock off for this certain website but I still can't access the website. I also installed Mozilla VPN last week. I'm using Firefox 122.0.1. What could be the problem?

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.

I often see a Shortcut on my New Tab that I have never gone to, which says "sponsored" on it. I do not want these ads. I have looked up the answer: https://support.mozilla.org/en-US/kb/sponsor-privacy?as=u&utm_source=inproduct I can manually delete a sponsored shortcut once, but this does not stop them from coming onto future New Tabs. My problem is, the long-term answer simply does not work. Settings -> Home -> Firefox Home Content simply does not contain a section that says "Sponsored shortcuts" and therefore this solution is not accessable. I am on Version 120 as suggested. What is going wrong? How do I prevent these ads from appearing on the New Tab page?

A virus file, from a website, keeps automatically downloading each time that I open my Firefox browser. I have tried clearing the cookies and history but the file keeps showing up as downloaded but the actual file is not in the general download folder? I only see where it download and says downloaded in the download list. The file contains a virus and also Firefox states that its dangerous. I never clicked to open the file.

How to stop this from keep automatically downloading when I open my browser? Please help ASAP Thanks

The file is: 7z2201-X64.msi download tracked to: 7-zip.org Virus website address: www.7-zip.org/a/7z2201-x64.msi

I'm at a loss here, problem is in subject line. This has happened for a long while and has persisted through various versions, I have attempted to:

- Alter my antivirus and internet protection settings to allow as much traffic as I can. - Download addons as XPInstall files and try and use the File -> Open File option in the Menu Bar - only returns a line about not having permission, despite having Admin permission.

My Firefox Version is the current 118.0.2 (see: attached image).

Thanks in advance.

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

I'm trying to configure my router and the instructions tell me to go to https://192.168.1.1. But the security settings will not allow me to get to that (local network) IP address, and ther.is no option to bypass the warning

Hi all!

I am using Firefox Multi-Account containers with Firefox 120.0.1 (64-bit) and the New Outlook desktop client with Windows 10(*). I have more than one Office 365/Outlook account, so I use different containers for each account.

Whenever I click on any link in New Outlook, it opens in one of my Firefox containers rather than in a default No Container tab.

Unfortunately, it opens in a container where I am logged into a different Office365 account than the one I use for the desktop client. This means any Office or organisation-specific links fail to work unless I copy and paste the link across.

Is there some way to force Outlook to open these tabs as No Container?

Thanks, penguinoid

In the recent update to Mozilla, all of my shortcuts disappeared. I had many, and can`t remember them all. Is there any way to restore my shortcuts from what they were a month ago? If not, I will switch to Edge.
