No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

Recaptcha isn't working in Firefox. It works in Chrome, Opera, and Edge with no issues, it will either just go to a check mark or open the window with the pictures to choose, on both regular pages and on the Google Recaptcha Demo site Google Recaptcha Demo site. But when I load a page that requires Recaptcha in Firefox, it just spins forever. It was working fine a few hours ago, and I didn't change any settings or anything in Firefox. I was filling out a job application and it worked fine, then I went to another job application and Recaptcha won't work at all, even on the Recaptcha Demo site.

I'm on version 125.0.3 (64-bit), on Windows 10. Not using a VPN or anything like that, just a standard Ethernet connection, with whatever Charter gives me.

Steps I've tried, none of which have helped:

1. Cleared Cookies. 2. Restart Browser. 3. Restart Computer. 4. Restart Modem and Router. 5. Opening Firefox in troubleshooting mode. 6. Ensured Firefox was up to date. 7. Reinstalling Firefox. 8. Turned Connection Settings to no proxy. 9. Turned off Enhanced Tracking Protection. (It's set on standard otherwise, and I didn't change it) 10. Release/Renew IP via Command Prompt.

I'm genuinely at a loss of what to do, after a couple of hours of searching around for solutions. I don't get how it just stopped working in the span of like ten minutes when I didn't change any settings or anything. Firefox is my main browser and it would be a tremendous pain to have to use another browser for any pages that require Recaptcha.

Any assistance or advice to solve this problem would be greatly appreciated!

I am using Firefox v125.0.2. When I open a PDF in Firefox it takes a lot of time to load. But, when the same PDF opened in the Edge browser it loads normally and scrolling through PDF pages renders fast. I have shared the screenshot of a single-page pdf loading taking quite a long time.

Could someone please help me with this.

Hi,

I have a Mac with Sonoma. Somehow a while ago I ended up with Firefox ESR, which I was told that will not be supported after September.

I am a non-technical user. While I do have Safari and Chrome, I would prefer to continue using Firefox.

Could you please let me know the steps to execute to somehow switch from the ESR version to the current normal version without loosing settings, bookmarks or ending up with problems? Thanks in advance.

The file-picker (when I choose any file related operation such as Open File, Save As, etc) on just one of my machines is far larger than my desktop size (and the window appears not to be resizable).

When I trigger any such operation I'm presented with what looks like a blank screen as I a shown part of the vast unused area of this oversized window. If I force my wm to allow me to move the window I can use the file picker with a lot of painful repeated scrolling around but otherwise it's unusable.

Any idea why firefox might be doing this or where it might have cached the file picker size? There doesn't appear to be anything related in about:config or userprefs.js

Starting up in trubleshooting mode doesn't have any effect on this.

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

GOOGLE CHROME WORKING FINE BUT FIREFOX AINT WORKING

THANK YOU

mail me at [Email address]

Starting this morning I suddenly cant delete or mark emails as read in Outlook.live.com. Even if I open an email, and it appears as read after that, if I refresh or leave the page and come back, its marked as read again.

I tried dropping all add-ons (a kill switch to drop all add-ons and re-activate them is still a feature I feel Firefox needs, I have to click every single one of them every time) to no avail.

I was in the process of writing this question on the Microsoft forums (which is usually like whizzing in the wind) when I thought to try a different browser. I had zero issues and Outlook.live.com worked perfectly normal on Microsoft Edge.

This HAS to be a bug in a recent update in Firefox

106.0.2 locks up Windows Explorer (Not Responding) on my Win 7 machine as soon as it starts. After restarting Explorer, it seems to continue working. I have seen this issue reported earlier.

When trying to click on links inside PDFs, the url is changed to undefined, producing an error message. For example, a Hostgator article is converted from https://hostgator.com/help/article/how-do-i-change-my-dns-or-name-servers to https://undefined/help/article/how-do-i-change-my-dns-or-name-servers

I have tried clearing the cache, troubleshooting, and get the same result in safe mode, and reverting back to Firefox default settings. And I still get the same result. I've attached an image of the error message.

Hello. I suspect there was a cyber attack on April 1 2024. All of a sudden,having problems crashing with more than 1 browser. My Brave browser would open,and then crash with multiple tabs that had been saved. My Mozilla history was cleared,and I want it back because I need to find all sites I have visited from time to time for logins etc,but they are now gone.I have tried importing all of my Brave history,login forms to Firefox,but not sure where to located them or where they would be stored.

Right now i am focused on getting a Firefox profile from before April 1

I have never had to deal with this sort of thing before so i am saying that i may be somewhat noobish on this.I just want some expert instruction on what to do here,and how to do it.I,m not 100 percent sure if i can do it correctly on my own by googling this myself,then attempting it.Brave continues to open then crash right after,so I dont know whats going on there with the userdata folder in the appdata folders with regard to Brave. Everytime i try to install an older version of Brave,it says i already have a curent version of it,and i dont want to uninstall brave then reinstall it again,or not sure if i should do this. ThankYou.

I was looking for an item that would be a couple of years back in my history, only to discover that my history now only goes back a year and 3 months… Exactly, as of today, I don't know if that's meaningful. Does anyone have any idea what might've happened, and how I can restore the rest of my history? Thank you!

I'm on a Mac using Mojave, with Firefox version 115.8.

On chrome I have several profiles and different ones use different LastPass (and other) extension services. EVERY PROFILE maintains it's OWN login information.

Firefox, however, does NOT ISOLATE PROFILES. On ANY Firefox profile, if I log into LastPass EVERY PROFILE is forced to use THAT information- even going as far as logging out and logging into the OTHER profile's information/account. This is 1990's level idiotic.

WHY are profiles SHARING LOGIN INFORMATION!? This is entirely stupid and defeats the entire purpose of multiple profiles.

I had this happen with Facebook logins, too... WHY does ONE profile FORCE OTHER profiles to change their login information?! WHY ARE THEY NOT SEPARATED?!

How do I solve this?!

it is the SINGLE biggest reason why I can NOT switch to Firefox again. Chrome does this. Chromium does it. EVERY Chromium browser does this. 10 years ago Firefox did this... and I left it when it QUIT doing this... when it BROKE profile separation.

Why is this STILL a problem?!

After switching to Firefox version 123, I encountered an error on our website: '1,000,000.00 is not a valid number.' It seems to be a form validation error, but it worked fine with previous versions of Firefox. The application is built using GWT (Google Web Toolkit). Any help would be appreciated. Thanks.

What Happened To The PASTE Option, When You Are Composing A New Email In Outlook  ?

If You Copy Something, Then Right Click In The Message Section Of The Email, You Do Not Get The Drop Down Menu With PASTE As An Option.

You Only Get The PASTE Option When You Right Click Into The SUBJECT Line.

Two issues using latest version of Firefox with Windows 10.

These 2 issues have occurred in the last few days

First I cannot attach my files to my emails using Gmail. I'm able to do this using Edge or Chrome

Second, normally when I used to start typing the name of my correspondent it would automatically complete. This is no longer working. I'm able to do this using Edge or Chrome

the attached printscreen shows both issues

Concurrent with the most recent automatic windows update (may or may not be the problem), Firefox with duck-duck-go will not go to almost any site. All I get is a spinning icon or a blank page, not even any error messages. This was even true trying to go to this page until I restarted in trouble shooting mode. Until I can get Firefox working again I have been using Chrome with duck-duck-go. Note any search, i.e. 'hotels in Italy' or even 'MSN' do the same: spinning icon or blank page!! Any help would be appreciated. Also I noticed that my bookmarks were missing and there was no bookmarks drop-down on my tools line. I have run malware bytes and it showed clean, same with CCleaner. I have re-installed Firefox; no difference. Please help. and also, any way to find and replace my extensive bookmarks list? I have reduced my privacy to near zero and turned off firewalls and all limits I could find while testing for that. That did not change anything.
