"My Firefox is opening in Administrator mode, which prompts me to agree to allow Firefox to make changes to my PC every time I open it up. I read that I needed to go to Properties and deselect all my compatibility settings but this doesn't work. Any suggestions would be greatly appreciated?"

Dear reader,

I wanted to completely removed Firefox because i had some issues. Instead om removing I probably refreshed FF.

Can somebody help with?

1. How to remove old FF data which is placed on my desktop and blocked for removal by admin rights. 2. How to completely remove FF without leaving any data (profiles, extensions)

I have tried to find this answers in the help sections but I was not able to find the solution for my situation.

Thanks in advance. With kind regards,

Ilco

I just downloaded the latest FF having had an old account. Working fine but I continually get a message that I am on windows 10, which is wrong. I am on Windows 11. The message has worn out its welcome. Is there a way to fix this.

Before purchasing, I verified that Mozilla VPN will work on Chromebook (shown on the FAQ page for the VPN). Since I can't install software on a Chromebook, how do I go about using Mozilla VPN on it?

I can no longer watch videos on Amazon prime, those included and the ones I pay extra for through an added subscription to mgm+ since the last update. What is going on? Is it the VPN data limit thing? If so, how can I turn it off?

I have a macbook air laptop (late 2010) and have been using the latest version of Firefox browser for browsing. It's one of the few browsers still available. Google is popping up with the message that my browser is no longer supported. Do you have any suggestions about a browser that may work (other than a new computer please)? Will Firefox be coming up with a new extended version that will work? Thanks!

I am not sure what to do first. I already paid for the VPN subscription. I reinstalled Mozzilla VPN but have not yet put the sudo lines in that are listed in the help on Firefox. Can you send me an email with instructions and any special sudo lines I need to intall so I do not get charged a second time. I heve the recovery code. I am new to Mint. Windows 11 started knocking out my hardware with power surges. Had to come from the operating system itself since the machine is hooked to a power backup that smoothes the current out. Converted everything to Linux. Like it. Life can be cruel... LOL Thanks so much for the effort. [edited] landline, but best bet is email. [edited phone# and email from community support forum]

I don't understand the problem. My accessing Firefox has become limited. I received a note to Upgrad to windows 11... I hae already upgraded. What must I do too have it recognised?
