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.

In the past I used to be able to turn encrypted sni on I did a firefox reset yesterday then I reinstalled my add ons

and I re-enabled encrypted sni by setting: about:config network.security.esni.enabled = true

but when I test it on https://www.cloudflare.com/ssl/encrypted-sni/ the test takes a lot longer and also everything is green except esni: "Your browser did not encrypt the SNI when visiting this page."

So something is clearly wrong, but I don't know what it is.

how do I fix this?

So after reinstalling Firefox my search engines changed and Google was removed completely. Only things left are Yahoo, Wikipedia, DuckDuckGo and Startpage whatever the hell that is. When I go to add Google as the main engine after clicking the three dots icon on the search bar where normally would be an option to add as a search engine, I don't have an option to do that. And when I'm clicking the Sign In button it tries to do something but returns to the Google home page. (sorry for the quality of the image, for some reason I wasn't able to take a screenshot)

I do not use the majority of keyboard controls in Firefox-- only Ctrl+F. Lately, I've noticed that using Ctrl+I in editor windows also pops up the Page Info window, which I have never used on purpose and am perfectly comfortable accessing via Firefox's menubar.

I have been searching for over an hour, and every Firefox add-on that I can find to fix this problem has been removed.

Ideally, I would like to be able to configure all of my keyboard shortcuts, but practically I will settle for being able to disable Ctrl-B, Ctrl-I, and Ctrl-U.

Yesterday I shutdown my PC running Ubuntu 18.04 while Firefox had a full screen window on each of my two monitors. When i turned it on today the window on my right hand monitor opened correctly. However, the window on my left hand monitor had these problems (see the uploaded image) it was not full screen. It was split into a window at the bottom of the screen that showed the expected contents and a black window at the top of the screen that took mouse input. Note the 'KCOM webmail...' popup by the mouse cursor over the upper window. A right click on the desktop had no effect on the left hand monitor, as if something considered the window full screen. After restoring down the window on the right hand monitor a right click on that desktop showed the expected menu. I recovered from the problem by moving the mouse cursor over the black window until the 'Maximise' popup appeared and clicking. The window then became full screen and has behaved correctly since. I have xpdyinfo and xwininfo outputs in case they are useful. I upgraded from Ubuntu 16.04 to 18.04 about 2 weeks ago and have been using Firefox almost daily since then. I have often seen it restart correctly when I restart my PC, although perhaps not with two full screen windows. I don't know if this is a known bug. I hope this information is useful.

Hi.

Why would you remove FTP? It's not obsolete, I use it for work, and a good one third of my browsing is easily ftp sites such as NetBSD.org, ftp.gnu.org and others. FTP is still used heavily.

I really really dislike that it's gone. I'd gladly spend 30-40$ a year for a paid version.

I've been using you guys back to Mozilla, Firebird, Netscape and even earlier ..possibly related was NCSA Mosaic. C'mon guys.. which Millenial decided FTP was obsolete and uncool because it was old? It's how most of the Open Source projects and distributions still move data around. :~( This is the first time since I started using Netscape/Mozilla/etc that you've ever done something I don't like. The last thing I want to do is be forced to use Chrome or some other garbage. Please.. bring it back or some sort of external module we can pay for to get browsing back. Please! I beg you. (Trying hard to be really civil and nice here ..truely baffled that it'd be removed).

A.

Move Tab: Ctrl+Shift+ PgUp/PgDn No Longer Works After Firefox Update

Hi. I'm currently using Firefox 86.0 in Linux (Ubuntu 20.04 64-bit) and for aeons I've been using Ctrl+Shift+ PgUp/PgDn to move tabs left and right, but a couple of updates ago I lost the ability to do so. Actually, I should say using the LEFT Ctrl and Shift buttons no longer works, as I ended up trying the right ones and I can still re-order tabs that way. However, I'm just so used to having my left hand working on that side of the keyboard, I always automatically press the left Ctrl+Shift, so I'd really like to get back to how things were until very recently. I was hoping doing another update to 86.0 yesterday would fix it, but it hasn't so here I am.

I've searched all over the web for a remedy, but all I see is people repeating the key combo, people recommending extensions that no longer exist (and I don't really want to install addons for something that used to be the default). I have not installed any addons for ages, have not tinkered with any settings (I can't even find any for key bindings) - all I did was let my system update Firefox, and that key combo was gone. (Note: since my system and apps get updated together, I can't actually be certain with was updating Firefox that did this, but I see no changed keyboard behavior elsewhere).

If anyone knows how to fix this, like a key in about:config or whatever, please let me know. PS: While searching the web, I've seen a lot of talk about related (Ctrl+Shift) combos I've never used - like Ctrl+Shift+ End to move the tab to the very end - and none of them work; the only Ctrl+Shift combo that works, and only with the right Ctrl+Shift, is Ctrl+Shift+ PgUp/PgDn for moving tabs left and right. I thought I should add that just in case it's related.

Once again my account is locked on one of my computers. It says the email was returned but there was no email sent to the address. Oddly, the account is locked on one machine, the one that has been logged on the longest, but my other three machines have no trouble connecting and syncing. This seems to have happened after firefox updated itself (even though I had it set not to. It also removed all the settings I had spent a considerable amount of time customizing)

Dear Mozilla Community,

I would like to know when Firefox will be dropping Windows 7 support? I readed on some websites that Google Chrome will be dropped support for Windows 7 in 15 January 2022 year so I would like to know if there are any plans by Mozilla Developers to drop support for Windows 7?

I don't have computers with Windows 7 but my friends asked me about this because they know that I am active community member of Mozilla but I can't answer because I don't know so this is why I asked you today about this.

Yours faithfully, Piotr

Hello, we develop an angular application. One of our users couldn't login any more. He uses Firefox 84.0.2 (64-Bit) under Mac. He get's the error `ERROR DOMException: The quota has been exceeded` in Console. Reloading Page even with COMMAND+R didn't work. We deleted the cashed files under settings, as displayed in https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/gallery/images/2018-04-29-04-08-27-fabea4.png (with both checkboxes). It only worked when we deleted the file webappstorage.sqlite in profile folder. Is that a bug?

Thanks in advance.
