Firefox Support Forum

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.

I have been getting "PR_END_OF_FILE_ERROR" when trying to access google or any of its services like youtube or gmail etc. I have not tampered with any of the default settings. Please provide me with a solution.

I just installed Brave, and clicked on "Import settings & bookmarks", then chose Firefox from a popup list

Without typing my password, or doing anything else, Brave then instantly imported all of the saved passwords that I had stored in Firefox. I can now view all of my most secret saved passwords of Firefox... in Brave

This makes me wonder, if Brave can instantly import (and display in clear text) all of my Firefox saved passwords, couldn't any other rogue app do exactly the same?

Shouldn't they be stored in an encrypted format, at least?

Am I missing something or are the passwords wide open that Firefox saves?

That download progress icon on the upper right used to always work and lately it has stopped. I have version 84.0.2 for Ubuntu Linux. I click on it and nothing happens. I like to check the speed to see if maybe I should switch to a different VPN server or not.

The drop-down list with known usernames and passwords extends until below the screen if there is a sufficient number of usernames stored. The funny thing is that the list is scrollable by mouse and arrow (up/down) keys, so it wouldn't be necessary to extend the list that far down. Just until the lower boundary of the current firefox windowwould have been sufficient.

The result is that I can't see (nor select) the usernames that are listed below the screen.

Firefox 75 64 bit on Fedora 32.

I hope this description was clear enough as I'm hesitant to include a screenshot showing all usernames involved on those site.

For anyone who wonders why so many logins: it's a list of email adresses currently in use in a webmail service.

Thanks.

Firefox on the new browser does not support Flash player even though all I repeat all game sites use Flash player, I tried to play one of my favorites online games and guess what it say that my browser Firefox has no support for Flash player in the general also YouTube will not play in Firefox because they use Flash player components, so turn Flash player on because there is millions no wait billions no wait trillions that use Firefox that love Flash player so please turn Flash player on please I and others want to play our online Flash player user games on Firefox. Thank you turn it back on

I just got a Pi 4b with 8gb. So I picked up SanDisk MicroSD 64 GB with 170Write.

Loaded the Ubuntu Desktop 20.10. It boots in 30 seconds. Wow...

Printer setup was super easy... Had to add Clementine to Play M4A music from itune files.

Ok... Loaded just fine. Plays Great. The Ubuntu 20.10 comes with Firefox 81.0 browser. My favorite Browser. Went out to my Favorite Anime site to play some video. Animefreak.tv

Error loading player: No playable Sources Found

Well the Video Codec plugin not there. Checked the Add-ons Enabled

 OpenH264 Video Codec provided by Cisco Systems, Inc.

This plugin is automatically installed by Mozilla to comply with the WebRTC specification and to enable WebRTC calls with devices that require the H.264 video codec. Visit https://www.openh264.org/ to view the codec source code and learn more about the implementation.

 ! OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly.

So I installed the new version of Firefox 84.0.2 (64-bit). ok. I am using it now. No Video play back in Firefox on Ubuntu 20.10. Same Problem. I turned on the Allow Automatic updates in firefox openH64 Video Codec. Maybe it will update and install. Well I am not holding my breath. Its to bad, because the Pi 4b is just as fast as my Laptop HP envy running win10.

If you can find a fix. I would be grateful.

When I paste an URL with a port number in the address field of a new tab and press return, then the port number gets removed.

Example: I paste "http://localhost:5707/typo3" and press return Firefox then tries to connect to "https://localhost/typo3/", which is SSL and has no port number.

How can I disable that behavior?

This happens with Firefox 84

Hi, I've just update Firefox, I found "old firefox datas" as a file. but passwords and bookmarks are lost. I've tried to find If the previous profile was registered, but there is none. Can you help? Thanks

Hi,

I'm using Firefox on Linux with i3wm. For some reason the whole autofill section is missing in Preferences/Privacy & Security section. I'm using version 84 of Firefox. I presume I'm missing some dependency, but I'm not sure what it is. Can someone suggest what this feature depends on to work.

Thanks

I am using Firefox 84.0.2 (64-bit) on Ubuntu, and I have been getting this weird behavior that works for couple of minutes where when I press the left Ctrl button, Firefox cycle through tabs quickly. It's really annoying behavior and I do not know where I can switch it off.

Thanks in advance for your help!

The menu bar at the top that has a red dot and a max/minimize button next to that has disappeared, and the browser now completely blocks the menu bar I usually have at the bottom of my screen that allows me to tab between applications.

When typing into a form, (ie a zipcode) you will begin typing amd the character you typed will highlight/select it self. Your next keystroke erases and the new character appears. For example. typing in the zip code 12345, would reult in the 5 showing up in the box.

This happened

A few times a week

== Installation Linux10-4

my computer is used by others. All is well except with a few sites which i would like to make unreachable. How to do it - what options do i have? E.g. reported sites can i add my own only with local effect? or other means?

Issue

Firefox is crashing or closing unexpectedly

Description

Problem: When I start FF in Linux, it crashes after the cursor is jumping for half a minute. Nothing is displayed. When I start FF from the command line, I get the prompt back after one second without any message. In safe-mode and with all extensions off it always starts. However, when I change something in the extensions' settings, it may start: If I start in safemode, deactivate all extensions, and restart - here it goes, with all extensions off. If I activate all the extensions again and restart - here it goes again, with all extensions on. If I delete one or more of the extensions' folders in the extensions-directory of the profile (i.e. sth changes about the extensions!), it may start again, too, but not in every case.

What could be the cause of this issue and how can I resolve it?

I use FF 3.6.8 in openSUSE 11.3. The profile-directory I use with FF in Linux is also used by my Windows-FF. As for extensions, I use Greasemonkey, Firebug and Web Developers Toolbar
