Using Windows 11 and a recent version of Firefox, if I open a command prompt window and enter: C:\Users\Admin\Documents>"C:\Program Files\Mozilla Firefox Esr\firefox.exe" --help

I get nothing.

But it works if I add "| more": C:\Users\Admin\Documents>"C:\Program Files\Mozilla Firefox Esr\firefox.exe" --help | more Usage: C:\Program Files\Mozilla Firefox Esr\firefox.exe [ options ... ] [URL]

Can anyone explain why?

Is it possible to change Firefox so that it works without "| more"?

Note that the above was on my Windows 11 laptop, but I'm sending this from my Windows 7 desktop. None of the suggested topics were appropriate, so I selected the first one "Accessibility".

I realize Facebook doesn't have a spell check feature,but is there a way my browser, Firefox, which I already have spell check enabled can somehow spell check Facebook when I chat? Can someone help? Thank you.

why everytime i use firefox the default web address is: https://hao.360.com/?src=lm&ls=n077c1cd59a

I am trying to upload a document on the Supreme Court portal (UK) but it won't work I am told because my browser has to allow pop ups and cookies. Where can I get Firefox to so allow?

The spell checker isn't working for me. I've found old answers to this:

"You can see which dictionary is selected if you right-click in a text area and open the Languages sub menu. At least one dictionary should be installed and have a check mark to indicate that it is selected.

   open the "Add Dictionaries" link to install a dictionary if you do not have one. 

The spelling checker is enabled if [X] "Check Spelling" in the right-click context menu has a checkmark.

You can enable or disable spell checking globally:

   Options/Preferences -> General: Language and Appearance: "Check your spelling as you type" 

You can look here for dictionaries:

   https://addons.mozilla.org/firefox/language-tools/ 

Note that for spell check you need a dictionary. A language pack provides string translations for the user interface.

   https://support.mozilla.org/en-US/kb/use-firefox-interface-other-languages-language-pack 

You can check the layout.spellcheckDefault pref on the about:config page.

   http://kb.mozillazine.org/layout.spellcheckDefault "'

But I don't understand what most of this means!

I don't find 'language' because I don't know where to find a "text box containing more than one line" I'd have thought this was one, but the option does not come up here when I right click.

I realise this is probably me being dense, but can someone help in simple terms, please? Thanks.

For the past few months every restart of Firefox disables LastPass. I did NOT have this problem previously. The version of LastPass is current (no updates found). I can go to Add-ons and the toggle is set to "on" but the icon in the menu bar is black. If I click the toggle off, then back on, LastPass comes on just fine. Why is Firefox disabling something that Add-ons says is loaded? VERY strange. Does NOT happen in Chrome. Thanks for any assistance. PITB!!!
