Ondersteuningsforum voor Firefox

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.

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.

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.

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?

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!

In MacOS Big Sur 11.1 on my MacBook, I have set MacOS to automatically switch between Light Mode and Dark Mode. But I notice that Firefox does not handle this well. When I have used my MacBook Dark Mode and switch back to Light Mode, Firefox still hangs in Dark Mode. The only way to solve this is to choose Light Mode in System Preferences instead of automatic.

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

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

I tried to play a program on the CBS site; I've done this two or three times a year for many years with no problems, but this time the site said it could not load its ads (error 113), and therefore would not play the show. I've always watched the ads before, never a problem until now. I checked the icon for Adblock Plus, and it said that something had caused it to reset to default; it said I could fix this by removing and reinstalling Adblock Plus, which I did, but that made no difference. I don't know what default is, or what I had before (a friend set up my computer for me, so I don't know details), but I just want the CBS site to be able to load its ads so I can watch the program. What do I do? Thanks.

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.

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?

What happen to the screen shot function? Its no longer in the search menu where it was before. Also all my add-ons are gone and when I try to DL one its says error.
