Ondersteuningsforum voor Firefox

Hy all,I can't access youtube.com. When I try Mozilla says:

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.youtube.com because this website requires a secure connection.

What can you do about it?

www.youtube.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.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

ANY FIX? TNX!

Hi there, I would like to “generally accept all cookies” for future surfing through the internet. I found this description (see below), but it doesn’t seem to work (help might me older before latest browser updates), could someone tell me how to set Firefox to accept all cookies? Thank you.

1. Click the Tools menu from the top toolbar. 2. Choose Options. 3. Click the Privacy tab. 4. Under "History" select "Use custom settings for history" from the drop-down menu beside "Firefox will." 5. Ensure that the checkboxes for "Accept cookies from sites" and "Accept third-party cookies" are both checked. 6. Click OK.

Why can a stupid failing script on a web-page, or even intentionally so programmed script disable the copy (and sometimes paste) functionality?

How can this be disabled/fixed?

One highlights a text (any text) on some web sites, Edit menu allows Copy, context menu allows Copy, one hits Copy, nothing happens. It's not even a page where someone wanted to "copy protect" some information.

Copy and Paste should work just as advertised since those were invented, how hard can it be to get that right? Even stupid Notepad never fails at it. And no, I don't care what the idiot who programmed a page though would be/should be best for me, I want Copy to be copy, Paste to be paste. This used to work in "original" Firefoxes even when page developers wanted to make it not work.

And yes, while on a given page Copy fails miserably, at the same time in other pages it works.

I would like to open a new tab when I open a new link instead of the last page I am on falling behind. The old page should remain and new link/page open separately. Example of what I would like. I open Firefox and my homepage is yahoo. I click on a bookmarked tab to go to youtube it opens in a second tab. I want the first tab to stay open on my home page and a completely new tab open youtube. that makes two open tabs now

The ability to edit and customize the headers and footers for printing was one of my main reasons for switching from Chrome to Firefox. Now I can't find where to do this. I don't know if it was a recent update or what but I am using Windows 10 Home. Please help so I don't have to find a new browser.

Hi,

I'm not sure what has happened but my Firefox browser no longer plays Amazon Prime Videos; quite simply the "play video" links don't work. I've played with the DRM settings, refreshed Firefox via the support options, and have installed the latest version of the browser. I'm running a Win10 desktop. Netflix works fine and Amazon Prime Video works fine through MS Edge, but I can't figure this one out. Does anyone have any suggestions that I could try?

Thanks and Regards

Hi There, Before I could sign up to a website I was directed to install a VPN service and they prescribed me to get NORD VPN and I thought but why not using the VPN service that I already have which is Mozilla VPN. So I tried to lock on to the site but I just could not now what do I do. I already pay for Mozilla VPN and if I do have to get Nord then I will have to cancel my Mozilla VPN. Please could you advice me what to do.

Long time listener, first time caller... :) [Seriously have been using and loving Firefox/Mozilla since 2004-2005, before that was Netscape Navigator, this is the first time I can recall having an issue that I can't find already written up and solved. Hence, this post.]

I've been having some odd issues with Firefox (85.0.2 64-bit) on my Intel Mac (Big Sur 11.2.1) for the past few months, and this morning decided to dig in deeper.

The backstory: When I’ve wanted to copy and image and paste it into Apple Messages, the images sometimes don’t send because Messages doesn’t support TIFF, WEBP, or PNG formats when sending to someone who doesn’t have an iMessage account (aka using standard MMS like to Android phones). So, I then have to convert the failed image to JPG, delete the failed message, and drag the saved JPG image file into Messages and can then resend it.

The issue: Today, I discovered that when I copy a JPG image from Firefox, and paste it into Apple messages, it seems that it doesn’t send because it appears to be either copied or pasted as a different format than the original image?

To reproduce:

1. Go to a web site with a JPG image ( http://www.lunarbaboon.com for example)
2. Right-Click on the JPEG image ( comicorder038.jpg for example) and select “View Image Info”
3. Right-Click on the JPEG image and select “Copy Image”
4. Paste into Messages to send to someone who doesn’t have an iMessage account
5. Hit enter to send
6. Wait a few seconds for failure
7. Click on failure Info
8. Right-Click on image and select Open
9. Preview shows the file as TIFF not JPG

To simplify:

1. Go to a web site with a JPG image ( http://www.lunarbaboon.com for example)
2. Right-Click on the JPEG image ( comicorder038.jpg for example) and select “Copy Image”
3. Open Preview and select “New from Clipboard”
4. Select “Tools -> Show Inspector”
5. Preview shows the file as PNG not JPG

What I’ve tried: Copy & paste of same image from Firefox - Safe Mode fails - So, doubt it is something in my Firefox config Copy & paste of same image from Safari works - So, doubt it is something MacOS related However, copy & paste of same image from Chrome fails too - So, maybe it is something MacOS related?

Any suggestions on what to try next?

I'm not normally a Firefox user, but need to use it for a particular resource. I'm used to having at least 2 windows open, one for reading documents/emails and another for pasting articles, etc. into an email. I found the Firefox icons for copying & pasting, but when I copy material from one window -- in this case, a PDF document--, I'm unable to paste it into an email in another window. What do I do?

I have had Ecosia set as my default search engine for some time but just now I did a search and it came up in Bing instead - something in the settings has been altered without my knowledge or permission. Ecosia is *not* available as one of the options under about:preferences#search and none of the articles I can find on making it my default actually work.

Any advice on how I can get back to the situation half an hour ago when if I typed a search phrase in the address bar the results came up in Ecosia?

Recently I've noticed that I am unable to print from Firefox. It doesn't matter if I print to a PDF or a real printer: I get the same error every time: "Print Preview Error, An error occurred while printing." If I do attempt to print to a PDF, the result is a malformed file that throws a sharing violation if I attempt to view it before closing Firefox.

I have tried all the various reset printer config settings on the help page Mozilla printer help , and even tried reinstalling FF. Everything else is OK.

Suggestions are welcome.

Is there an easier way to view two tabs on the screen at the same time - "split screen" fashion? One can open one tab in a second window and adjust to have one window on the top half of the display and the other on the bottom. But this is a awkward.

See screenshot of this. It shows downtown Minneapolis in Google maps at two different scales. (Note that the I35W crossing of the Mississippi in the upper right corner is the one that collapsed in 2011).

One can switch back and forth between two tabs (maybe after moving the two tabs to be adjacent). But this is still suboptimal.

I use splitscreen in my text editor all the time (vertically or horizontally) and find it very useful. I wish there were an easy way to switch to/from split screen in Firefox.

BTW I searched the Firefox "Find help..." for: "split screen" tabs and got 1640 hits! I looked at the first 10 pages and saw nothing relevant.
