A known bug? target="_blank" and window.close() do no longer work together since Firefox 72

Assume you create a new window (pop-up) using javascript and have its content be something like this:

<html>
<body>
  <form action="some_action.php" target="_blank"> 
     ... some form fields ... 

     <button onclick="window.close()">
        submit in new tab & close pop-up
     </button>
  </form> 

  <a href="some_page.php" target="_blank" onclick="window.close()">
     open link in new tab & close pop-up 
  </a>
</body>
</html>


If you click the button "submit in new tab & close pop-up" the following should happen:

  1. Firefox submits the form in a new tab (because target="_blank" is set in the <form>)
  2. The pop-up closes itself (because onclick="window.close()" is set)

And if you click the link "open link in new tab & close pop-up" the following should happen:

  1. Firefox opens the link in a new tab (because target="_blank" is set in the <a>)
  2. The pop-up closes itself (because onclick="window.close()" is set)

However, what happens instead is this:

  1. Firefox only opens an empty tab, i.e. the submission of the form / the opening of the link fails
  2. The pop-up closes itself

This clearly seems to be a bug, right? Is this a known problem? I tested it with older versions and the problem apparently was introduced relatively recently with Firefox 72. More precisely, the form submission bug was introduced with Firefox 72 Beta 1 and the link opening bug was introduced with Firefox 72 Beta 7.

In Chrome and Internet Explorer both cases work as expected.

After update to 76.0 which "..strengthens protections for your online account logins and passwords, with innovative approaches to managing your accounts during this critical time:" Firefox has "strengt away" multiple passwords. Set to default the search engine and removed all of my addons.

Hello! I didn't find any feature request forums, so I am writing here.

I would like to be able to attach a container to a saved bookmark, so if I want to open it, it would open in that container by default. That would help greatly keeping my user data separated.

Hi

I looked at a couple other threads on this problem, which said that you have to install a dictionary and (for example), "You can see which dictionary is selected if you right-click in a text area and open the Languages sub menu". But when I right click in a text area, the context menu has no mention of spelling or languages, and I can't find any place in the Options where one would install a dictionary.

Besides which, why doesn't Firefox tell the poor user that he has to install a dictionary, or put something about it by the check-box in the Options that refers to the spelling checker? And why, in the past, did I never have this problem with Firefox, but only now with a new computer? (Windows 10 as before.)

I have been using Comodo's Ice Dragon for many years but, as all development stopped after Firefox v65, I now wish to go back to Firefox, however I need all my open tabs from Ice Dragon in this current version of Firefox v76. Both browsers are synced and indeed CID's tabs do appear in my Synced tabs menu but I prefer to have them on the top as open tabs. Is there a way to do that other than by opening them one at a time please?

I have an android with Firefox installed, and a Mac where I also use Firefox. When I first installed Firefox on each, the bookmarks matched. I do the bulk of work on my laptop, but occasionally have articles I wish to bookmark on my phone. I have done a sync, but when I go to access the bookmarks on my phone, they are not updated to what is on my laptop.

When I check to see what devices I have connected through Firefox, my phone does not show up, and when I hit the link to "connect a device" all it does it take me to a link to send a text to invite my phone to install it. Which, it's already installed.

I really need these bookmarks to talk to each other properly. What am I missing?

Hi Everyone,

Trying my luck here as a last resort. I cannot read videos on FF (I end up with the following message "This video file cannot be played.(Error Code: 102630)") except Youtube ones.

I read few articles and already tried the following: make sure I have the latest version of FF, uncheck "Use hardware acceleration when available", install FFMPEG, install K-Lite (and restart FF each time).

Nothing worked so far so any other tips from the community would be great.

I'm using Windows 10 and have a couple of add-ons only (LastPass and uBlock origin).

Thanks a lot in advance,

Max

Hi.

I love Firefox specifically because it lets me use Ctrl+Shift+N, i.e. reopen a closed window. I have this one window with several pinned tabs (Facebook etc.) and a few other open tabs (some reseach, YouTube etc.) where I keep things that I need to return to. I essentially NEVER close this window without reopening it, because it has the most important things I need. Sometimes I open a second/third window to work in (I had an online exam the other day, so I opened that and my materials in a separate window, so I can cycle through them more easily).

When I open this second window, sometimes I close my main window (it has quite a few tabs so it slows Firefox down). I then always reopen it using Ctrl+Shift+N and never had a problem. Well, I closed it now (then opened one or two other new windows), but when I wanted to reopen my main window back up, it just refused to. It's gone from "recently closed windows". Interestingly enough, at least two other windows I closed BEFORE it (one from yesterday, that I did unrelated googling in; the other was closed a couple minutes before the main window, it was an emoticon set that pops up from one forum) were possible to reopen, but not my main window. Now I can reopen just 3 windows, and I don't understand where they are (there used to be up to ~10 or so).

I want to know why I was able to reopen windows I closed long ago, but not the most recent one, and whether there is a way to fix this and get the main window back. I have effectively lost ~40 tabs that I had open (some research articles, pinned social media, some stuff I wanted to read etc.) that I can't even reopen unless I find them through my History (and hoo boy, that'd take a while).

Thanks for any info. Have a nice day.


SOLVED - EDIT: The amount of windows that can be reopened can be fixed as mentioned below. Lost window probably cannot be restored, sadly. EDIT 2: Actually it can be restored! See the answer to find out how. Both these lovely people gave me answers to my questions, kudos to both of them.

Version 76 has serious problems in Mac Mojave and Catalina. I'm thinking of moving to another browser if the problems aren't fixed in a few weeks. In Mac Mojave, the UI sometimes blinks and sometimes becomes black. I had to restart the app but it happened quite frequently. After updating to Catalina, all shortcuts are unusable, most right click menus are blank and even the menu bar is blank. When hovering the mouse over the menu bar, nothing displays, just blank menus. Sometimes, the app starts up with default UI although I customised it a bit. In those cases, I had to close the tab or even restart the app.

I'm getting disappointed and perhaps I'll move to another browser soon.

I used to be able to open a .pdf file when surfing with Firefox. But now a very strange thing happened, Firefox still opens those files as usual but when I click on the download arrow, Firefox no longer downloads the pdf file... Nothing happens. I tried pressing print to pdf and that works. But takes much longer compared to just downloading, I would very much appreciate your help if we could fix this issue.

I didn't install any recent new addons or anything.

My problem is that when I join a Google Meet, and get the Firefox popup that says "Will you allow meet-google.com to use your microphone?", in the "Microphone to share:" dropdown, it only lists the mic on my webcam. However, I want to use the headset mic I have plugged in.

I'm on Windows 10, with a Logitech C920 HD Pro webcam, and using the on-board audio on a MSI MPG Z390M Gaming Edge AC motherboard.

I know there's nothing wrong with the on-board audio or headset, because I can select and use this mic in Discord and other apps just fine.

Also, if I unplug the webcam, then Firefox will offer to use the on-board mic, but of course, now I have no video.

In both cases, it never offers to use the audio line-in, which I've wanted to use to present to a meeting the output from of another device. I've tried installing Voicemeeter, hoping that would solve all my issues, but Voicemeeter's virtual microphone also never shows up in the "Microphone to share:" dropdown.
