Firefox 技術支援討論區

Hello! I'm a new user to Firefox switching from Google Chrome.

I'm looking for some type of extension or something that will allow me to view websites in a side panel.

Page to Popup extension is okay, but I'd like to be able to have multiple websites I can just click on to see the brief view in the web panel.

Any help would be greatly appreciated!

On the entertainment media site Buzzfeed, clicking on a post of an embedded Twitter video gives me a blank white image. No error message like "Unable to play the file". I did a clear history, cache & cookies and refreshed Firefox. I ran the apt update for Ubunto. It had been operating smoothly in the past. If I go to Twitter, it plays. It just goes blank when I click on the video embedded in the post.

Thank you for any assistance.

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.

About Firefox says 76.0.1 (64-bit)

I can't upload any files on any website. For example, trying to share photos on Facebook – nothing happens. It's supposed to bring up the Finder menu and let me pick the file to upload.

I just switched over from Chrome and am on MacOS.

Recently, when a popup window appears, the toolbar doesn't have buttons for any of my addons.

In about:config, I'd intentionally set dom.disable_window_open_feature.toolbar to true (following the solution provided in: question 1206512).

Previously, this was successful in ensuring that popup windows got the full toolbar, but now it has stopped working.

I'm not sure exactly which release this started with.

Steps to reproduce:

1) Set dom.disable_window_open_feature.toolbar to true.

2) Visit https://jeffersonscher.com/res/popit.html and follow the third link.

3) The window that pops up has no toolbar icons for the installed extensions.

I'm on FF 76.0.1

The text color of the locations in the URL bar is a mix of black and grey ... black for the website and grey for everything else. All I wanna do is change all of the text to black. How can I do this? I just need the code to plug into my userChrome.css file.

I wanted to delete one item from the Top Sites section of my Home Page on Firefox, but instead I removed the entire row. How can I get it back?

Thank you for any hep you might be able to provide.

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.)

When I right click on a link and choose "open in new tab" or highlight text and do a search from the context menu, can I set my preferences or about:config so that browser does not jump to the new tab immediately? In other words, I want to stay on the page I'm on and have the new link tab load in the background. I hope I have explained this adequately. Thanks.

I imported bookmarks from Safari on my Macbook Pro. When I click on the 'Bookmarks Menu' and 'Other Bookmarks' about half of the folders do not show any bookmarks. However, when I open the Bookmarks through the sidebar, everything shows up....all folders and contents. So all my bookmarks were imported but half of the folders' contents do not show up if I go through the Bookmarks and Other Bookmarks menu. Going through the menu is easier so I hope someone has a solution. Thanks.

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.

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.

Hey, I have a problem with addons and Firefox Sync

On my computer I have 3 addons installed, but I dont need them there because they are useless on this system. But on my Linux Laptop I need these 3 addons to be enabled. Both Profiles are using Firefox Sync to keep the same data. That means if I disable/enable them on one of the devices it affect the other one.

Is there any way to prevent that?

Thanks in advance

Firefox very slowly opens websites from other sources - Evernote, messenger, office word, PDF. It's not really the fault of a too slow laptop (i7-1065G7, 16 GB frame memory, SSD NVMe + current drivers).

It makes my work very difficult, is there any solutions?

My online bank page won't load. After log in I get a blank white page. I can log in with other browsers. I can load other web pages with Firefox. Using 76.0.1 Thanks

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?
