Firefox 技術支援討論區

Hello, I am using firefox 83.0 and I don't want to update it (Why? Because I've an old PC with poor hardware and the playback of online videos is lagging/shuttering in releases after 83.0)

BUT firefox 83.0 doesn't support private fields which make some webpages unable to be loaded. the private fields was supported starting in release 90.0 and I'm using 83.0

So, I need a way to make firefox 83.0 support private fields, Is that possible? Is there a certain files should I edited or replaced to make it support private fields?

Any ideas would be appreciated.

When I opened Firefox, the message below popped up for a few seconds, then disappeared: CAD 3.8.2 - Some site data, including 1 Cookie(s), removed from 1 domains(s), including addons.mozilla.org...

Can anyone explain this, and should I be worried (CAD is a Python term used in uploading code). Thank you.

Using YouTube for example...

Previously, when I bookmarked a page/video (URL), if the newly bookmarked page (URL) had previously been visited, the bookmark would be displayed in the Sidebar (or Toolbar) with a typical "YouTube Play Button" icon (favicon). But, if the newly bookmarked page (URL) has never been visited, then the bookmark would be displayed in the Sidebar (or Toolbar) with a default "Globe" icon (favicon).

I almost always create bookmarks by dragging links/URLs from the browser client area to a folder in the bookmarks list in the sidebar (and sometimes/rarely, to a folder on the Bookmarks Toolbar). But the same happens if I manually create a new bookmark to a "Visited" or "Un-visited" page.

Recently, this behavior just changed "without notice"...

Now, when I drag a link/URL from a the "Recommended videos column" on the right side of a YouTube page/video, to the bookmarks list in the sidebar, the bookmark is ALWAYS displayed in the Sidebar (or Toolbar) with a typical "YouTube Play Button" icon (favicon), regardless of whether the page had previously been visited, or not. Also, existing bookmarks for un-visited pages that were previously created, and were previously displayed in the Sidebar (or Toolbar) with a default "Globe" icon (favicon), are now displayed in the Sidebar (or Toolbar) with a typical "YouTube Play Button" icon (favicon).

How can I bring back the previous behavior of displaying bookmarks of un-visited pages/URLs in the Sidebar (or Toolbar) with a default "Globe" icon (favicon)?

I want to use a command option to open a new blank tab in a specified portable instance of Firefox using a specified profile.

I constructed my command like this:

"Path-to-Firefox-executable" -profile "Path-to-Profile" -new-tab "about:blank"

It partially works (it opens the correct instance of Firefox and uses the correct specified profile) however it always opens about:newtab instead of about:blank.

Seeing as I am specifying the exact page to open, any New Tab settings in the browser should not matter, and I should just get the page that has been specified in the command.

If I manually type about:blank into the url bar, then a blank page opens as expected, so the url is correct, it just won't work for me as part of the above command line.

Does anybody else have this issue? How can I get this to work correctly?

Hi.

Is there a way to display a column in the bookmark manager (Ctrl+Shift+O) which would show in which folder each particular bookmark is?

Is there a way to search for bookmarks (in the bookmark manager or the bookmark sidebar (Ctrl+B)) by specifically excluding certain (bookmark) folders (e.g. MySessions, Save for Read Later, BSP2 trash folder, etc)?

If the above is not available, please kindly consider those ever since important features.

Thank you very much :)

I'm running the latest FF under Win7. Seems that whenever I go to the Merriam-Webster (dot) com site, after a few seconds, my disk activity light goes solid, and the FF CPU usage spike to 10-25%. One time, to regain control of my system (because everything seemed hung) I actually had to resort to the physical power-down switch. Obviously I immediately ran a virus scan upon coming back up (scan showed all okay). Now, if I stay away from Merriam-Webster, FF behaves normally. But it's a damned dictionary site. I occasionally will need to use it or stumble into it. I've used MW in the past without problems. Does anyone know what's going on?

I am using Windows 7 and Firefox 115.5. When I close Firefox, it stalls and after a minute I get an error message saying Windows Explorer is hung up. Then if I can get an option to close the program. I have tried many ways to exit Firefox but nothing helps this. Thanks.

Since support is being discontinued for W7 Firefox, would someone please recommend the best version of Firefox for Windows 7? Security is not a concern, since I have reliable 3rd-Party security setup(s) for my Windows 7 systems.

Thanks!

If I am on a web site and click a link to another page on the same website Firefox opens a new tab rather than displaying it in the existing tab. How do I get Firefox to NOT do this?

Dear ladies, dear gentlemen,

on another Computer, when using Firefox, I am now constantly getting a Norton notification of a malicious domain request 22. The problem does NOT arise with the Opera browser installed on the same machine. What shall I do? Uninstall Firefox seems to be the best solution. Scans do not reveal presence of malware. On this computer, similar OP, this does not happen, but I use it much less.

Thanks a lot, Alexander

Currently running 115.4.0esr, 64 bit... I have auto updates disabled via the json policy, yet every day I keep getting the warning about an update required and must go to download it... How can I disable the warning? It is annoying.

As well, while here in the forums, I did the "about firefox" thing to get the version and despite my settings, FF downloaded an update and wants me to restart to install it... what if I dont want it?

I get that you folks want to make things .... right... but there have been many changes that I am not fond of. Please respect my privacy and let me update by my own choice.

Thanks :)

I have one site that produces PDF files that Firefox will not open correctly, my other browsers do not have a problem with PDF. What should I be looking for to correct.
