Every time I try to upload a file to the Microsoft Copilot 365 I keep getting the "Error Occurred Please Try Again" But when I switch to Chrome. I can upload the same files with no problem. Does anyone know why I get the "Error" with Firefox?

I'm simply trying to email someone using the email link on their site.
The link is a mailto link which requires an email application (which I don't have). All I want is to copy the link to the clipboard.
Firefox lets me right click the link and copy the email address, but this doesn't allow me to provide the required Subject specified by the site's author.
I could have sworn Firefox used to have this feature. Netscape and IE certainly always had it back in the day.
How do I stop sites I visit from being automatically added to my homepage shortcuts? Desktop PC, Win11, Firefox 143.0.3 (64-bit) Thanks.
I have an ongoing problem with Firefox opening Youtube. It does it intermittently, not not 100%.

With Firefox 144, there is unasked for/unwanted AI introduced. How do I ensure that all AI is completely disabled in my browser? I found a link describing some settings, but want to confirm this will disable ALL AI in the browser. I don't want it, don't trust the privacy/security holes yet to be found and would prefer it was not included in Firefox to begin with. The list I've found is:
Will this do it? What about:
browser.ml.chat.nimbus
Do I need to clear that field to ensure I don't get some auto opt-in in the future as more and more of this "stuff" is put into the browser?
Why not leave Firefox as a security/privacy conscious browser and put out a separate AI browser (FirefoxML?) for those that are not as concerned. How does Mozilla ensure that no information is leaked through AI from sessions for professionals that must protect physician/patient, attorney/client information or other legally confidential information?

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.
Does anyone know how to solve this?
Kind regards.

The scrollbar slider isn't displaying correctly. If I grab the screen, zoom in, and look very carefully, it is possible to see that the slider is a very slightly different darker shade of grey to the rest of the scrollbar, but it's almost impossible to see, so something is clearly not working properly here. The scrollbar should be highly visible as it's the most often-clicked control of the entire browser.

Unlike before, many sites that I visit regularly, I am now having to log in every time I visit, including support.mozilla.org.
Did I unknowingly change something, some setting? or perhaps it's due to an addon?

I am used to having a Firefox for my personal Mozilla account, bookmarks and sessions, and Firefox Developer Edition to be logged in my work account, where I could use everything I need to work in a separate environment.
Recently I changed a job. Logged out past-job@mail.com from Firefox Developer Edition, logged in with present-job@mail.com and... I still can see old bookmarks.
- I cleared history and new bookmarks: nothing - went to about:preferences#privacy and clear all the data: bookmarks still there - tried Help > More troubleshooting information > Refresh Firefox…: all the same - reinstalled firefox@developer-edition with brew: nah - eventually, logged out from presetn-job@mail.com in Firefox Developer Edition and personal@mail.com in Firefox; uninstalled both, deleted everything related to "mozilla" and "firefox" was able to find in my system: unsuccessfully
The last thing I didn't try yet is burning my laptop in favor to a new one.
Where are those bookmarks? Why nothing is helping?

Is it possible to make a donation to Mozilla without providing so much personal information? I got a message on Firefox today asking for a donation, but when I tried to do that, I was asked for my home address. It's a general rule of internet marketing that people who use the internet would rather do anything than pay for something, so it's bad psychology to impose unnecessary conditions when you're asking for a donation. I don't have to provide my home address when I make donations to other organisations, so why does Mozilla need my home address? I apologize if this is the wrong place to ask this question, but I can't find anywhere else to ask it!
Thanks,
Shaun.

All of my bookmarks have been disappeared with a new automatic update (9/22) and now I'm left with no bookmarks at all. My other devices were not synced because my work computer needed different links saved. Any easy options for recovery? The bookmark management tool shows no options to import bookmarks and clicking any of the restore or import options does literally nothing. This is a huge issue for work flow and is putting me out of schedule. Why would an update remove ALL bookmarks? Seems like a serious over look in function.

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

I have Firefox installed on three Windows Desktop Computers. On one, I just cannot delete Bookmarks, no matter what suggestions I try. Verify Integrity of the database produced no results. I do not, for a variety of reasons, sync bookmarks (or anything else) between the three installations. Experienced user that has spent far too long on what should be a simple issue.
