How do I change the email account inserted by Firefox when I click on an email link?

I have previously changed the main email address (added secondary address, swapped secondary for primary, deleted secondary) but when I click an email link in a web page to write an email to the web page business, the old deleted email account is used instead of the new one. This old address is not listed at all as far as I have seen in my Mozilla Account.

Used to work, and does work in the regular version of the desktop app, but no longer works in the beta for desktop 135.0b9, says: "Could not load the image"

I posted this and was told it was ;posted, but then I got a not found error when I tried to view it, so I'm trying again.

I set a site to use firefox as the default app for ftp not realizing ftp support was removed from the browser. I have been trying to get the dialog back that will allow me to change it. I downloaded filezilla to use for ftp. However, I am unable to get the dialog back that will allow me to change apps.

Can someone help me get the dialog back? And, before anyone suggests it, resetting firerfox to the default settings is not an option.

These are technically two separate issues, but both pertain to functionality of the mouse and keyboard. Whenever I right click to bring up the menu, the options (despite being functional) do not appear in the menu proper. Instead there are just empty buttons. In addition, certain hotkeys aren't working at all. Ctrl+C and Ctrl+V to copy paste are doing fine, but Ctrl-T and Ctrl-W to open and close tabs respectively do nothing. Neither of these issues were happening yesterday.

On Firefox 128.14.0esr (build 20250811113756), Linux/X11, the setting browser.tabs.hoverPreview.enabled does change back to "true" every few days, or perhaps browser restarts.

How can I turn off tab previews reliably?

My friend recommended this browser to me. When I tried to customize it, I couldn't find an option to change the hotkeys to my preference. I consider this feature important since I use it for work. Can I do this somehow, and is there any plan to add such a feature to the settings?

I'll be honest, I have strong ethical objections to "generative artificial intelligence" (genAI) on a range of issues, and I have seen no sign that the industry is capable of, let alone plans to address any of them. But I'm not here to debate genAI, I'm here because I require a work enviroment and tools that make it as easy as possible, preferably default, to avoid genAI.

I'm deeply disappointed that the Mozilla Organization has decided to add genAI to label tabs in Firefox. Even if I didn't have ethical concerns, I would still be disappointed at the bogged-down performance and genAI hallucinations that make this change categorically a downgrade.

I respect other users right to do things I find harmful, and the Organization's authority to make decisions. I treat genAI much as I treat smoking, everyone gets to make their own choices, but I have the right not to be exposed to second-hand smoke. Having genAI options default to on is like having somone blow smoke in my face, and when they can't be turned off, it is like having an acquaintence who insists on smoking in my home: I won't have them over (use their software) any more.

I'm in the process of kicking the people who smoke in my house out, and minimising my exposure to "second-hand smoke" (unwanted genAI). I've been a Mozilla user and proponent since the Organization was founded, and was a Netscape user before that, so I don't want to lose an old friend... but I am looking into other options.

Hi It isn't really a question, but it get to know and learn how to use Firefox efficiently before I converted from Safari to Firefox. I knew much more in Safari than in Firefox. Once I know more about Firefox, Firefox will be a default browser in my desktop,mac. Thanks Ted

I operate with several to many windows open (and many tabs). Firefox (Mac) used to list the open Windows in the Window menu in the order I originally created/opened each window. A while back, FF started sorting – and re-sorting! – the list of open windows alphabetically according to the Tab that is currently active in each Window. This means that the window appears in different places in the Window menu list according to the name of the Tab. I DO NOT LIKE THAT because the it makes the Window hard to find.

Is there any way to set this to operate the way it used to - keeping the Window list in the order first opened, regardless of which Tab is open?

When using the the chat especially when on either of my laptops. I think it would be useful to be able to minimize/hide the chat but not have it completely close so you can stay in the same session.

In my head I see it working by adding a simple minimize button next to the close button. When it minimizes, the icon for the chat can stay highlighted to alert that it is still active. Also, when switching from chat to other options like bookmarks, history or tabs. If there is a current chat open it should use the minimize behavior so the same chat is still active when you navigate back. So essentially the only time the chat closes or resets is when you close it.

I uncheckd the checked box labled "check spelling as you type" to disable it and it's still showing spellcheck. It's gettingin the way of me typing and being able to spell on my own. It's extremely annoying that I can turn off a featire and the progra will just ingore that I've turened it off. Why is this an actualy problem? why doesn't this button just work? I want it OFF... Please.

One of the websites I need for school requires pop-ups. I can't click on the button to permit pop-up windows for just that site because it only flashes for less than a second and it is grayed out. I tried to go to preferences to disable the pop-up blocker, but the checkbox to disable it is grayed out. I created a new profile, but the button to disable the pop-up blocker is grayed out on that too. I now have to use chrome for this website because I can allow pop-ups on that browser.

My question is why is this setting grayed out? And how can I re-enable pop-ups or at least edit the exception list because that is grayed out right now too. Any other tips for troubleshooting similar issues in the future would also be appreciated.

I don't know which question best describes my question. I have always used Firefox because it had two boxes for searching. This meant that you could type a search into the second box while keeping the first box open. Now that second url box is gone. How can I get it back? I used it all the time!
