Hi, Imaging that, firefox is open, I clicked on a button that opening new window, how I can merge this 2 window in 1, in fact I wanna have that new window as a tab.

Google Chrome have this already.

Thanks !

Can't connect with the just downloaded version 66.0.4 to virtually any site - not to Google, not to NYT, not even to Mozilla - Firefox won't accept ANY certificate! Following errors appear (examples): "Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to addons.cdn.mozilla.net because this web site requires a secure connection. What can you do about it? addons.cdn.mozilla.net 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 web site, 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 web site’s administrator about the problem.

Or: Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to www.nytimes.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. What can you do about 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 web site’s administrator about the problem.

The explanation is as follows: Someone could be trying to impersonate the site and you should not continue. Web sites prove their identity via certificates. Firefox does not trust www.nytimes.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates. Error code: SEC_ERROR_UNKNOWN_ISSUER

No problems whatever with other browsers. I'm sending this with Safari.

Hi

Running Firefox 71.0 (64 bit)

Well seems Firefox has been messing this up again.

Anyone have the new work around solution to get my tabs back on the bottom again. They were fine this morning then shut down and went out to lunch and when I came back they were back on the top again after months of being where I wanted them below my bookmark bar.

Thoughts on this?

Thanks Dave

I'm trying to watch videos in Firefox. Youtube works but Xvideos does not. Firefox pops up a window asking me:

>> "Opening xvideos"."com ###.mp4". >> which is: MP4 Video (16.4MB) >> from https://cdn77-vid.xvideos-cdn"."com >> >> What should Firefox do with this file?

My only choice is: Open with Windows Media Player x86 (default)

suggestions?

I'm running Windows 7 Firefox 76.0.1

Thanks!!!!

Until several weeks ago, new windows created through Javascript with window.open() worked. We could pass the new size, and other features, e.g. menubar, toolbar, etc. and they would show up. As of v.76.0 this is no longer true. The parameters are ignored. If we use no parameters, the menubar, etc. do show, but we can't control any new window features. We have not changed our programs at all, and window.open() parameters still work correctly in Chrome, Brave, Edge, etc. How do we get Firefox to recognize the window.open() parameters (again)?

Hi, I'd like to get rid of the status bar at the bottom left corner. I know it goes away and it seems impossible to remove. But is there any way to remove it? I add an image to show what I want to remove. Thanks in advance!

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

I paid Firefox $28 for unmarked videos. Now the mark, the stamp in the corner of the video, is back. I would like my money back or the non-stamped videos back. Who do I see about that?

I just updated Firefox to version 81.0 in Linux, Windows and Mac, but the credit card autofill option is still missing from the Preferences menu.

I followed the instructions from here:

https://support.mozilla.org/en-US/kb/credit-card-autofill

Yes, I am located in the US.

Hello, I would like to know how to remove 'other bookmarks' folder from the right side of bookmark toolbar that showed up suddenly on my browser, it's right after the arrows to show more bookmarks. I can't seem to find a way to delete this.

How can I get a list of all the sites that are set to "always open" in a specific container? For example, I want to see a list of all the sites set to always open in the Work container. I would also like to edit the list without needing to manually visit each site.

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

With the new v85 of Firefox... for Microsoft Print to PDF...

the defaults for print headers & footers has changed and is no longer available to edit or even view. It seems as though my settings remain in place for other printing options like my physical printer but even there the options are not editable or viewable.

There used to be a "page setup" option but I have not be able to find this anywhere anymore.

• Bulleted list itemhttps://support.mozilla.org/en-US/kb/how-print-web-pages-firefox#w_changing-the-page-setup

I'm assuming that it has to do with the bug fix for pdf printing but doesn't seem that it should be an intended outcome of the fix.

Any work arounds anyone knows about or has found?

I'm trying to take off this "Extension (Tabliss)" tag on my url. I have followed the instructions down below from another Firefox support forum: https://discourse.mozilla.org/t/make-addressbar-text-extension-name-of-the-extension-shorter-or-hide/28026/3

The instructions I followed are listed below:

"Users can apply custom style rules to modify Firefox’s toolbar area by creating a userChrome.css file. This takes about 10 minutes so when you have time to take it slowly and carefully:

(1) Set up your chrome folder and userChrome.css file following the five six steps in this article:

https://www.userchrome.org/how-create-userchrome-css.html 45

I have a boring video there if you like demonstrations.

(2) This is the code to paste into the file. You can edit the file using Notepad or a better editor. Make sure to keep it in a plain text format with a .css file extension (not .css.txt).

See improved rule down in: Make addressbar text "Extension (Name Of The Extension)" shorter or hide

/*
   Hide Extension Name in the identity area unless
   hovered for half a second (updated for Fx80)
*/
#identity-box.extensionPage #identity-icon-labels,
#identity-box.extensionPage #identity-icon-label {
  visibility: collapse !important;
  transition: visibility 250ms ease-in-out;
}
#identity-box.extensionPage:hover #identity-icon-labels,
#identity-box.extensionPage:hover #identity-icon-label {
  visibility: visible !important;
  transition: visibility 250ms ease-in-out 500ms;
}

(3) Firefox should read the file at its next startup and apply it to every extension page you load."

Edit: So, yeah, I need help getting this tag off. I'm new to Firefox so it could be something obvious I'm missing. I have also tried CTRL+SHIFT+R to reload the page for changes and also closed and reopened my Firefox entirely.

Thanks in advance.

I'm using Firefox 85.0.2 . . . I was doing this (below), to customize my header and footer, but in this version of FF, I no longer see this in Options - only in: about:config . . . keyword "footer" . . . there, I would have to change it for 5 different ways of printing (to printers or to PDF)

I need to get rid of printing the URL in the footer - many times, it's too long, and I don't need it.

Where did the Page Setup option go?

I see in the current Print Options, you have to go to - More Settings / Margin / Custom - to see those. Why would they put this so many levels down?

It used to be: File / Page Setup / Margins & Header/Footer . . . "Customize" Headers & Footers:

Option 1 (left) . . . there are two leading spaces:

 > > &T
 > > &U . . . &D . . . &PT

Option 2 (left) . . . get rid of the ">"s, and just have the two leading spaces:

 &T
 &U . . . &D . . . &PT

A recent Firefox update has totally disrupted our ability to print from browser windows. There used to be a "Print Preview" button that allowed us to set things up the way we wanted them. That's now missing. As a result, stuff that used to cost us for ten pages now costs us for twenty pages. Also, when we print double-sided, the second side prints upside down.

This strikes me and my wife as a horrible development, and we would like to go back to the old version ASAP!

Firefox updated and now my tabs are above the address bar, I hate it. I have went through all the information I could and created a new chrome folder, downloaded the css and changed user preferences but it sets the tabs to the bottom of the screen not just below the address bar. I think I need a different set of code for the css but cant find a copy. Does anyone know what to do?
