Diễn đàn hỗ trợ Firefox

For internet service I have to use a mobile hotspot for my desktop pc. The problem is that the mobile hotspot ip address is about 300 miles from where I am. So doing a search, I get results for that area that I am nowhere near. How do I stop this?

I use Win 10 Pro. If I want to copy something - a document or site address or use any other control in the menu, sometimes the menu options appear and sometimes they don't. Sometimes nothing happens and I have to hit Esc several times to get a program or menu selection to work. Occasionally, I even have to reboot. I seldom use other browsers but when I do, they don't seem to have a problem. I'm thinking of resetting Firefox but I'm concerned about everything I'll lose. I've tried to simply update my browser but it doesn't help. Suggestions?

Even when I tell the printer to print a range of pages, it will only print the first page. I spoke with HP Support already and they said the problem is with Firefox, not the printer. The drivers are updated.

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.

Firefox has done some kind of update and has removed all my bookmarks, settings and all my passwords I had saved which were important and I don't know how to go back to the way it was. I have lost 5 years worth of stuff, including EVERYTHING I had saved that I needed for my studies. Someone please help! I'm not very tech savy, I did not click on anything for this to happen. My browser has done usual updates before and never had this issue. Please help!!!

I switched my local keyboard layout and tried to type my language(myanmar-burmese) in firefox. But It doesn't work in my firefox browser. Instead of my language,it's typing English. My language keyboard work in other applications i.e terminal, text editors, etc. How can I fix it? suggestions please!

After upgrading to FF 84, my previous sessions are no longer saved and restored unless I restart in Safe Mode.

- I have Restore previous session checked in Preferences.

- I have opened new windows and tabs and one by one disabled and restored every add-on that I have had enabled and quit and restarted each time, until every single add-on has been disabled, and still the previous sessions are not saved and restored.

- I have looked in the sessionstore-backups folder with each restart, and there is never any file for the previous sessions in it.

- Again, even when there are absolutely no add-ons enabled, the previous session is not saved and not restored.

- Again, only when I restart in Safe Mode is the previous session saved and restored.

What is the solution?

QUESTION: I FOUND A FILE ON MY DESK TOP IT IS TITLED- Old Firefox Data DATED 11/1/20 IT HAS ONE FILE FOLDER IN IT: jlu3luel.default-release ~ DO I NEED IT? <<<< THAT IS MY QUESTION... DO I NEED IT?

Just got a list of vulnerabilities from acronis 2021 for CVE-2020-26971 CVE-2020-26972 CVE-2020-26973 CVE-2020-26974 etc. is there a newer point release being worked on ?

1. 1. Ought to have a "Suggestions" in the topic list.

My observation is that you have just changed the Bookmark Lookup function to show only bookmarks. It use to show folders as well. When I wanted to find a bookmark, it is often to move it to a more "consistent" place in bookmark map, and you can't do that any more.

Also on the Bookmark Edit page, it would be awfully helpful to have it's folder label displayed there as well.

I have been using firefox along with xfinity for years. Firefox always logged me into xfinity automatically, BUT now is has stopped and each time I log out I have to re-enter informatioion. I have looked at the configurations and all look okay. Anyone able to help me out?:)

Thanks very much Allen

I am trying to serve a print view and redirect the user to the page they came from right after printing (or cancelling). This works fine in Chromium with the following bit of JavaScript code:

  function printPageAndRedirectTo(redirectUrl) {
   window.addEventListener("afterprint", function () {
       window.location.href = redirectUrl;
   });
   window.print();

In Firefox, however, nothing happens at all. Debugging shows that the callback is called, but the href field remains unchanged.

This is mysterious to me. Any ideas what the reason might be?

Firefox version is 84.0.2, Chromium 87.0.4280.88 (both from the Arch Linux repositories).

Edit:

Here's a fiddle to illustrate. Redirect to Wikipedia works in Chromium but not in Firefox: https://jsfiddle.net/xnazLb6p/1/

Edit 2:

Another one to show that the problem here is redirecting from the event listener, not redirecting itself: https://jsfiddle.net/xnazLb6p/2/
