Firefox Community Forum

Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

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

I have Windows 11 on my Desktop PC and an up to date version of Firefox.

On two separate occasions I attempted to download past statements from two different credit card websites. Both times the requested statement failed to download, or even proceed to the next screen.

I called Customer Service for one of the Credit Cards and was told to try Google Chrome. I was forced to use Google Chrome to successfully download and view the requested statements.

I have been able to download and view the same information from the same websites in the recent past.

Could something have been changed in the Settings or what?

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.

I've used FF for years. The last year, it does not function correctly on about 20% of sites. I suggest focusing on making it compatible, rather than requiring sites that are perfectly coded. I may have to drop FF soon.

In Firefox, recently I am unable to download pdf documents. I get the message "download failed". If I request the same download using Chrome, I get the download immediately. But Firefox is my default browser and it's a nuisance. This only started in the past month or so.

Hello,

When I attempt to open Firefox, I am getting a pop-up screen saying:

135.0.1 not compatible with min version >= 135.0 max version <=135.0

Also, I am being advised to reinstall Firefox. Do I need to uninstall Firefox first?

Windows10, Dell Laptop

Thank you,

Petrik

I have used Firefox for ages now and love it. I have noticed in the last few months that some functions on some web sites are not able to be accessed. Such as submit, place an order, and the like. I have to use another browser. Is there any reason for this as I really don't like to use any other browser other than Firefox but it seems to be that I have to. Is there some way that I can get around this?

Late yesterday, all my bookmarks disappeared. Whenever Firefox ask me to update, I do. Please advise if they are stored anywhere from which I can retrieve them. Probably close to a thousand.

Software is Preventing Firefox From Safely Connecting to This Site

news.google.com is most likely a safe site, but a secure connection could not be established. This issue is caused by Private Internet Access, which is either software on your computer or your network.

What can you do about it?

news.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

   If your antivirus software includes a feature that scans encrypted connections (often called “web scanning” or “https scanning”), you can disable that feature. If that doesn’t work, you can remove and reinstall the antivirus software.
   If you are on a corporate network, you can contact your IT department.
   If you are not familiar with Private Internet Access, then this could be an attack, and there is nothing you can do to access the site.

So I download the latest update of Firefox. New feature: Edit PDF's in Firefox. Sounds great.

Click on the Try it Now link ... downloads PDF to computer. What? What happened to Edit in Firefox? What am I doing wrong?
