Firefox supportforum

I have been using Firefox on my Mac for years with no problems. Recently, however, I have been having trouble running YouTube. I get to the correct page for the video I want but the video itself does not show up, just the background for the page. Any idea what I might have done to create this problem?

So for some reason I have two versions of Firefox on my computer (Windows 64 bit), I am logged in and using one of them, and the other is just there. I could log in there but I don't want to, I just want to get rid of it. Links from Telegram open in it, creating a second Firefox window instead of opening in another tab in the already open Firefox window, which is very inconvenient. The windows list of programs which can be uninstalled only has one Firefox (I've tried deleting and reinstalling, it doesn't help). But when I try to choose a default browser I get 2 icons to choose from which look the same (see screenshot). What the heck? How do I manage this!

How can I set the default language fir Firefox to English? Currently browsing results always come up in language of my geographic location, for example, Romanian while in Romania. Never had this problem before.

I cannot open the login page on my hosts website. My host is https://ventraip.com.au/ based in Melbourne Australia. That means I cannot access the Cpanel so I cannot upload data on my web site. Other people can open that login page on their computers buy I can't on mine. Where is the problem?

This is the message I get

'Secure Connection Failed

An error occurred during a connection to vip.ventraip.com.au. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

I just got a new to me computer and it has Firefox 125.0.3 (64bit) but I was more comfortable with what I had Version 124.0.2 (64 bit). What would be the downside of changing to what I had? I just use it for home use and browsing. How would I go about making that change. I'm not to knowledgeable about computer language and stuff. Thanks, Larry

I'm currently on a very old version of Firefox simply because the new versions, each time I try the latest versions, seem to not have the function the old one has. Remembering the websites I put into the address bar. The version I am currently using did have a issue with shuffling the order of the sites based on 'use' but setting Firefox to Private mode kept the websites locked in order and did not make them shuffle if one was clicked more often than another. Is this something I can do on the current version because I tried and looked for a way to do this recently but I kept getting 'autofill' results from google when I just want to be in Private mode, have the websites I frequent be the only ones listed when I click the address bar and not have them shuffle or have any other website I'd type into the bar not add itself to the list. If this is or isn't possible let me know.

Concurrent with the most recent automatic windows update (may or may not be the problem), Firefox with duck-duck-go will not go to almost any site. All I get is a spinning icon or a blank page, not even any error messages. This was even true trying to go to this page until I restarted in trouble shooting mode. Until I can get Firefox working again I have been using Chrome with duck-duck-go. Note any search, i.e. 'hotels in Italy' or even 'MSN' do the same: spinning icon or blank page!! Any help would be appreciated. Also I noticed that my bookmarks were missing and there was no bookmarks drop-down on my tools line. I have run malware bytes and it showed clean, same with CCleaner. I have re-installed Firefox; no difference. Please help. and also, any way to find and replace my extensive bookmarks list? I have reduced my privacy to near zero and turned off firewalls and all limits I could find while testing for that. That did not change anything.
