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.

Hi,

I'm not sure what has happened but my Firefox browser no longer plays Amazon Prime Videos; quite simply the "play video" links don't work. I've played with the DRM settings, refreshed Firefox via the support options, and have installed the latest version of the browser. I'm running a Win10 desktop. Netflix works fine and Amazon Prime Video works fine through MS Edge, but I can't figure this one out. Does anyone have any suggestions that I could try?

Thanks and Regards

The ability to edit and customize the headers and footers for printing was one of my main reasons for switching from Chrome to Firefox. Now I can't find where to do this. I don't know if it was a recent update or what but I am using Windows 10 Home. Please help so I don't have to find a new browser.

I wish to know how to fix this issue (magnet links) ? I've installed bittorrent, but not showing on d.a.s page, after refreshing Firefox. Error msg: This file does not have an app associated with it for performing this action. Please install an app or, if one is already installed, create an association in the Default Apps Settings page.

In MacOS Big Sur 11.1 on my MacBook, I have set MacOS to automatically switch between Light Mode and Dark Mode. But I notice that Firefox does not handle this well. When I have used my MacBook Dark Mode and switch back to Light Mode, Firefox still hangs in Dark Mode. The only way to solve this is to choose Light Mode in System Preferences instead of automatic.

Firefox colour addon removed the whole existing theme, replaced everything with it's default selections.

I use a custom theme, I just want to change the text colours on the menu bar, tab bar and bookmark bar. But the color addon destroyed the whole theme when I made any single change. I had disable and enable the theme to restore it. How do I import the theme to color addon so I can edit it?

When printing PDF document from web site using Firefox part of the left text is cut off. I have tried "Fit to Page" and shrink to 90% and still have issue. I can print this web document with Edge with no problem. This problem just started in the last several days. I am using Win 10 professional on a Del Opti-Plex 5080.

one of my google accounts, which I have been able to sign in through firefox for years, suddenly started giving me an error message after entering my email address on the google sign in page. I have another google account and I'm able to sign i using firefox just fine. The error message given is:

This browser or app may not be secure. Learn more Try using a different browser. If you’re already using a supported browser, you can refresh your screen and try again to sign in.

I'm using a windows 7 box and Firefox 85.0.2.

I'm able to sign in just fine when I use google chrome. I've cleared cache and data in the browser. I'm not sure what else to try. Any suggestions? Any other information I can provide to help identify the problem?

I had so many problems with it, I went through downloading different "session save" add-ons, I know what solution you guys will give me, I've done most of the posts' instructions, this is more of a complaint post.

When Windows boots up and you had Firefox open before you shut down last time, it will open anew, automatically, with your previous session, but it's on the end of the list of things that launch on startup.

Forgetting you had it on and clicking the browser again, will open a new session with the home screen instead of the previous session, then when actual session Firefox launches it's a 50/50 whether it will be in home screen as well, or actually in your previous session. Now here is the fun part. If you close the new window with just the home tab, that will now become the latest session, so your previous one will be deleted.

How to get around that? Move your home tab into your session instead of closing the window, it works 100% of the time... But can we, not start a new session if you close the home screen, or if you close just 1 tab it doesn't count as a different session. I dunno, just throwing ideas out there.

Hope this reaches those with the same issue, or people in positions to fix the issue, if anyone wants to use session saving add-ons, I took fancy to Tab Session Manager and Easy Session Manager, though not perfect, I don't advise for over 150 tabs.

I'll try to be as active on this thread as I can be, thanks for reading through! :>

I'm using a Surface Pro 7, running Win10H. Firefox had a brief period when I first installed it where the on screen keyboard would appear and work, that stopped after a few hours and has not worked since. I fiddled with the settings on both Firefox and my surface, though nothing has changed. Un/re-installing did not help, thought it could reset something. Any fixes or advice would be greatly appreciated.

For clarification, the Accessibility Menu on-screen keyboard does work, but the tablet-specific larger keyboard does not function. It does open and type in other applications.

To show Firefox menu in english, I added English to Language Settings. Now is not removable at all: the "Remove" button is non-active... And English seems to be the primary language EVER: each word written in Italian in every website is underlined in red as "mistake"... How can I remove English language from the settings ? Thank you

Hello, I have recently purchased a new laptop computer as my old one crashed. It is running Windows 10 which is new and unfamiliar to me. I am also using Firefox V85 as my default browser. In building my new bookmarks folder list I found the folder icons are coloured a nasty shade of grey. However, running Firefox on older operating systems (eg XP or Windows 8.1) the folders are a pleasing yellow colour. I have exhausted myself trawling the web, Youtube, and the Firefox help topics in trying to find a way to change the folder icon colour, but with no sucess. Please accept my apologies as I suspect that this question will have been asked before, but I cannot find any references to it. If anyone knows how to do this, please be aware that, whilst I am literate, I don't necessarily understand arcane computer terminology so I would welcome a simple key stroke by key stroke walk through. If there is a fix, it needs to work in both the Toolbar and the Sidebar. Many Thanks Chris

Hi, After Firefox offered to repair my session because it advised it was working too slow, I have lost all my favourites, passwords, toolbar, history... how can I restore everything ?

Thank you,

Hello,

My Firefox routinely shuts down while I'm using my 2018 Macbook Pro, and the problem began when I updated my IOS to Big Sur This is a systemic problem with non-native apps ever since installing Big Sur. Apple won't address the problem unless I confirm that my non-native apps are compatible with Big Sur. Can you please confirm the most updated version of the Firefox Browser is compatible with Apple's Big Sur IOS? Can you also let me know if other users have experienced problems and if there is any fix?

Latest update blocking website like indeed from loading in information about employers and other sites too. Every update makes firefox worse. I started using other browsers because now some video's don't work either. Last thing I saw was a QUICK pop-up that said something about bits of trackers now being blocked. Well lots of things are being blocked and making browsing a miserable experience. I tried using the standards system in options. Can't find anything to make it work. Allow lots of things and nothing is working except to probably make the web browser more vulnerable to creeps. Please undo your current update and stop making so many updates. I've had three in the last two weeks and every time they screw up the browser more and more. Just stop it!

My account is not syncing to any Firefox browser, extensions, passwords, bookmarks non of this attributes will be loaded to my browser back after re-installation, What might the issue be?

Hi, Once upon a time, when restarting a session, closed with some pages still open, Firefox was proposing the list of all pages that were open at the termination moment, asking to CHOOSE which pages we wanted in this new session. That feature was very very useful, allowing a fast closing, and a 'meditated' and comfortable restart.

Now, from a couple of years, it seems that the only choice is to have back ALL the pages again, or none... Is maybe this useful old setting hidden somewhere ? Thank you for your help... I find irritating loosing features in updates !

My laptop location in Firefox is using my former home location. But when I do the same Weather Google Search or Google Map website in Chrome, the location is my current location in North Carolina. This true whether I'm logged into my Google account or not Signed in to my Google account.

In Firefox I've checked Tools/Options/Privacy & Security/Permissions/Location/Settings. It lists 3 sites that have asked for access to my Locations: google, home depot and BedBathBeyond. Yet when I use Google to search "weather", it gives me Wayne NJ. This section will not let me add Google Maps.

In Security I changed Block Pop-ups to continue to have a checkmark but added google.com and maps.google.com as exceptions and restarted Firefox. Google Maps still shows Wayne NJ and weather sometimes shows North Carolina but mostly shows Wayne NJ

Are there any other settings in Firefox I need to update? Or are there settings in Windows I need to update.? I'm using Windows 10 and Firefox 85.0

I loaded Firefox onto a new Win10 laptop yesterday and made it the default browser (against the "recommended" Edge). Today some websites are loading very slowly (e.g. PCMag home page takes 30 seconds to load). Some https sites load normally and others are slow. I refreshed Firefox, did not fix it. Is there something I can do?
