I cannot access my primary Firefox account, don't have a two-step authentication app configured for the account, can't find recovery codes, and don't have a logged-in device. In addition, I subscribe to premium services linked to the affected Firefox account, so I'm now unable to access them as well. To ask this question, I created a new Firefox account.

What should I do now? It seems I'm stuck paying for services I can no longer access. I can't even cancel the premium services since I can't access the affected Firefox account. How can I contact Mozilla Corp?

New computer, running Windows 11, McAfee LiveSafe came with for 30 day trial. I use Firefox, have since 1997. Just added Mozilla VPN. Old computer ran Xubuntu. Windows 11 needs antivirus because it's Windows. So. How compatible are McAfee LiveSafe and Firefox with Mozilla VPN? What suggestion, if any, does Mozilla have for an antivirus program that will work well for Windows 11 but not mess with Firefox and Mozilla VPN? Thank you.

Firefox only shows a black box when i try to run an embedded video. It works fine on other browsers, specifically Microsoft Edge. I ran it in troubleshooting mode which fixed the problem temporarily but reoccurs when computer is off and then turned on.

More and more I'm having to go to other browsers like Chrome or Edge to open certain websites as they do not work through the Firefox browser. Why is this and how can i get them to work before i change browsers permanently?

I travel for work and often stay at IHG properties (Holiday Inn, etc.). I have Firefox as my default browser; version 99.0. I cannot login to their wifi using Firefox; I have to copy the address and paste it into Google Chrome and after confirming my information I am able to browse normally until the next day; It must reset at some point.

This is the web address for the network login: https://www.msftconnecttest.com/redirect

I read this article about Captive portal detection: https://support.mozilla.org/en-US/questions/1314194 I change the setting per the article hoping it would take care of my concern but it did not.

Thank you!

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

An error occurred during a connection to www.facebook.com. SSL_ERROR_DC_EXPIRED What in the world? does Facebook not keep up with its own security? or is this a Firefox thing?

When I try to log into chase.com, I'm told my (FireFox) browser is out of date, but I am running the latest version. What can I do?

I've been changing this over many years. Now I have two additional browsers to use so I'm not updating until I can, once again, organize the browser to fit my needs.

This extension, even if it is Firefox's extension, I do not want. It is hindering my ability to get my schoolwork done your browser that I like to use. I really do not want to have to make the complete switch to Edge. I should not have to add this extension that I do not want.

Please tell me how to fix this problem: ever since I allowed Firefox to upgrade, I cannot load pages for banks/credit card accounts. I can do it on my Apple phone and IPad. So I believe it is a Firefox problem. I prefer using my desk top computer to pay bills. Please help me sort this out. I will change browsers if you can't help me. I'm not being snarky, just very upset that your upgrade did this to me. I am a 81 years young senior female, so please don't get to techy with the answer, keep it simple for this old brain. BTW, I cleared cookies and cache, didn't help. Thanks, Norma
