Yesterday all of my PDF documents were converted or changed to "Firefox HTML Documents". The change was made without my consent or action, after I yesterday used my laptop File dropdown menu to "export" and convert six new Word documents into six PDFs, which were saved on my Toshiba laptop and intended for uploading and filing with a governmental body. My Toshiba laptop runs Windows 10. This error and unauthorized action by Mozilla Firefox affects many dozens of PDF documents that I have created and saved over the last decade and causes me great inconvenience and harm.

How can I restore my PDFs to their correct form and format as PDFs, not "Firefox HTML Documents", which may not be uploadable or usable with court, government or other website portals?

How can I prevent Mozilla Firefox from making this unauthorized error and conversion of PDF document again?

Additional Edit of my question - After reading comments from numerous others that had the same problem of unauthorized change of PDFs to Firefox HTML Documents, I have the following additional question. How can we contact someone at Mozilla to make them stop their destructive highjacking of people's documents? I'm a lawyer, so in my world tampering with someone's document, that is required by law to be submitted as a PDF, can have serious real world consequences. I'm sure this is true of many other people's documents in many other fields and businesses. Who can we contact at Mozilla to insist that Mozilla's tampering with PDFs has to stop immediately? If Mozilla will not stop misappropriating control and tampering with documents, people should be compensated for any harm that Mozilla causes to such a large number of people.

good day, I made a few changes on Facebook, then I battled to log in to Facebook again. I tried with Chrome NO PROBLEM, I also tried Edge also NO PROBLEM. Now I use a password manager, so I KNOW I am using the same password all the time on my PC. BTW on my iPhone I can also login without an issue. So I uninstalled Firefox 2x now using Revo uninstaller and removed all files from my PC. On Re-installing Firefox I installed as a fresh install..... But when I open it, Firefox, all my recent sites are still there??? When I try login to Facebook, again it asks me to confirm I am human.When I do that it takes me back to the FB login screen. The I try and login MANUALLY with my credentials that work on all other browsers, and the same thing happens and so it loops around and around, so I cannot login to Facebook from Firefox - and I cannot fathom why not. In the second installation i removed ALL passwords in Firefox. I then logged into Facebook on Chrome and made sure I do not have @FA in Facebook which I do not, so I'm really stymied. Hope someone can advise/assist with resolving this very strange issue. Should you need Screen grabs please let me know and I will get them to you

cannot log onto att.net for my email acct...using firefox............microsoft edge is no problem...it says it is due to a connective issue? Help!...... thanks..

Since I updated firefox, something has been wrong. Twice now it's like the browser has just stopped working. When I use google, and I change the search. The page html keeps changing back and forth between the two pages.

What's worse, is that the connection stops working. I can't get any of the pages to load. I thought it was the WIFI connection but then I started using Microsoft Edge and it's fine. It's not the WIIF. It's the FIREFOX MOZILLA browser that is not letting me load the pages. Which is annoying as hell because I use YouTube a lot and the videos won't play. Or stop loading in the middle. There has to be something that can be done about this.

This website has always opened in Firefox until the last couple of weeks https://www.tvinsider.com/tv-listings/?codeword=highwaypatrol

I do not seem to be able to connect using PureVPN. Their Helpdesk advise me to sign into Chrome or Edge, neither of which do I wish to do. I wish to stay with Firefox. However, I am also a 'recipient' of the latest Windows 10 (so-called) upgrades, so it may not be anything to do with you guys. Can you help, please? Cheers, Mike Courtnadge
