I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

I try to install Firefox on a HP Z1 G8 desktop under Windows 11 Pro. The first time I get a warning that a .dll is not available or so (I dont know what this warning is precisely, becaus it pops up for 2 seconds only ) , and firefox is not well installed, reinstalling goes without warning, but still Firefox starts and then stay dead, no sites, no settings. I know the security in this computer is very thight, but other apps install without problem and functions.

Why Firefox cant be installed where other apps can ??????

who has experienced this also and has a clou ?? thanks Ferdinand

I'm trying to access a video on meethook.live. I did so in 2021 using the Firefox browser, but for some reason, it won't work anymore. The kind people at Meethook.live suggested using Chrome or Safari, but I don't want to use either of those browsers. Unfortunately, I can't figure out how to change any settings to make it work. I tried a few security settings, dropping a few protections I had set up, but that hasn't helped. Can you suggest anything?

I've used Firefox sporadically for a couple of years. Last week it would not open. I refreshed, then uninstalled and reinstalled and it still won't open. What do I do now?

I asked a question to add details after an answer but when I have an error when I click to the "Post a Reply" button.

Hi I am the admin site owner of the above site on th site we have a widget that lets us monitor who is in our teamspeak server from the home page this was working great until I and other members updated to firefox 121.0.1. 2 days ago, now we get this message in the widget frame insted.

Firefox Can’t Open This Page To protect your security, server.nitrado.net will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

I contacted Nitrado support after reading this https://support.mozilla.org/en-US/kb/xframe-neterror-page They say they have fixed the issue but it still present after reinstalling the widget, clearing cache (server and firefox app) and server restart, this is effecting all our uses who use firefox, which is all of them :( can anyone help?

I generally go here https://www.tafesa.edu.au/ and select 'learn' and log in there. Now I just get a window saying 'Taking you to your organisation's log in page' and circling dots and it stays there forever. That window is, I think, from Tafesa. So it sounds like a Tafesa problem.

BUT: I use Edge and it all goes smoothly and I log in. Which sounds like Firefox is not handling something from that site.

Anyone got any ideas on what i could do to get Firefox working on this?

I'm trying to open a web page, which worked perfectly until about a week ago. The address is: https://xdaforums.com/f/xiaomi-poco-x3-pro.12163/

I now get a popup window, which tells me that I'm trying to open a "application/octet-stream (377 bytes)" and gives me the option of "open with" or "save file".

I don't want to do either, just view the page as before.

Many, many months ago I did mundane search and opened a webpage in a new tab, as per normal. Nothing particularly stood out about this search and when I was done, I closed the tab. I didn't do anything different. I didn't save a bookmark or change any settings. I just looked at the webpage and then closed it when I was done. (It was a web article on some random tech site, if that matters)

Anyway, now whenever I open up my Firefox browser there seems to be a random chance that this previously closed tab will open on loading. And when I say random chance, I'd say about 1 in 5 chance. It doesn't always happen.

Just to be clear: I do have the browser set to restore my previous sessions. This is a setting I want to have on. However, this tab was not part of my previous session as I specifically closed it - and continue to close it every time it opens itself. Also, my Homepage is set to default and nothing else.

Not only that, but there are two very peculiar details about this case that make it very, very strange: 1. When I originally opened (and closed) this tab, I was using normal Firefox. I have since switched to Firefox Nightly. All of my other tabs that I like to keep open had to be searched and loaded up manually, one by one, after I did the switch. This one tab, however, is just showing up on its own. 2. Opening Firefox on a separate devices (second desktop PC, laptop, android phone) will occasionally load up this tab.

I do have my browsers set to sync, which is what I'm assuming is why it's following me around. But I don't understand why nor how to stop this specific page from loading after I keep closing it time and time again. Plus, why aren't any of my old tabs from my old Firefox browser following this same behavior after moving to Nightly? - I've closed hundreds, if not thousands of tabs. Why is this one following me around?

I accidentally deleted the blue star on one of my book-marked items and am struggling to get it back. Its very useful so i can see immediately if somethings already been bookmarked. Plus I could remove easily and/or put into other folders. All solutions appear to be to go to customize firefox and to drag and drop in some bar at the top of the page BUT when i do this it STILL doesn't come back. HELP!!! (Please explain in total laymens terms and don't nauseate me with technolingo.)
