Firefox Support Forum

Hello, I'm reposting this question in better topic. After loading Firefox to 87.0 Now when I click on a "contact" button from a site I get 'courrier' from Microsoft. How can I get my xxx@free.fr address (zimbra mail) instead. Help from mozilla doesn't help me! Years ago the same problem was solved with a button on the first opening of the mail box.

Upgraded from 60.9ESR to 78.8ESR Tons of empty white space being wasted in my address bar drop down, and the preferences+addons pages now only occupy half the screen so I have to scroll more to see all my options, click to fully read text boxes and open sub-menus?!

How can I make these things more compact? The Customize options don't affect them, though I've changed the "blow-up" address bar behaviour using policies.json.

Upgraded to a new Firefox version. Lost the ability to separate the Homepage from New Window behaviour. Is there no way to specify these two things separately? It seemed to be working fine when I first upgraded, but in the options it shows everything as "Blank Page", so if I want to change my homepage URLs, I have to set it to that and if I do that, it undoes the separation of the homepage and new windows and I have to go set it again in about:config...? One of my most used features was this separation of the Homepage with New Windows, gave me a lot of control.

The default Amazon search that comes built-in with Firefox points to Amazon.com. Is there a way to search for other marketplaces, like amazon.com.au or amazon.sg ?

How to change print marigins units in new Firefox version? In earlier versions I did it like this: 1)about:config 2)print.pirnter_name.print_paper_size_unit = 1

unfortunately it doesn't work now :(

Guys, tell me how to change the background of the firefox reader, the white background loads the eyes heavily, tried to use the Dark reader extension, but nothing has changed for me

Is there any way to remove the close-window-button or the whole tab part. I want to avoid the user close the browser. I know there is Kiosk mode, but kiosk mode seems cannot keep back button

icons/ buttons for ublocker and privacy badger disappeared from upper right browser bar. extensions still installed but no access from running browser and no >> so where did they go and how do i restore them. reboot dosn't work, reinstall dosn't work, removed firefox and reinstalled extensions worked only until reboot of firefox. was trying to harden firefox just before the came up missing.

I've seen the archived suggestions do disable quick find. They were to uncheck 'search for text while typing'. I went to do that and it was already unchecked. How can I disable this? It's a problem when doing math homework.

When I use the download option to "Open with", in many cases a .zip file to be opened in file explorer, it does not open the file and shows this error that the file has been "moved or missing".

Hi i would like to know how i can change the font size of my Firefox Menu.

i already change the size of the layout whit "layout.css.devPixelsPerPx" but it didn´t change the font size of the tabs or the menu. i did some research and found the userCrome.css technique to change some fonts sizes. i already change the font size of the address bar, PopMenu and tabs. But when it comes to the Main Menu, and bookmarks the font still in the same size. i also try changing the fonts size on preferences but nothing has been working.

i guess there must be a simple command line to add in the userCrome.css file to fix this but i can find it.

if some of you can help me i will appreciate very much.

i am working on a linux machine. thank you very much

But it's not working for me. I tried both of these, false and true, but text still gets selected after one click like before any alterations were made

   browser.urlbar.clickSelectsAll
   browser.urlbar.doubleClickSelectsAll

When I'm browsing articles or news stories or what-have-you on the web, I would like to be able to read the information I came from without all the distracting stuff on the sides and top (or worse, the kind of pop-ups that can't be blocked, because they are JS-generated in the same page). Article mode is great for this, but can I have it automatically enable to help prevent me from distracting myself?

Hi, I have an important question. When I open firefox on my desktop the first website that comes up is not the normal Firefox homepage, its the very irritating <Startxxl> website, and I don't need this add-on. But I really don't know how to remove it.

Thank you for your help.

I would like to use the amazon.com (and wikipedia.com) search engine and keyword. But since I have installed a non-English version of Firefox (or maybe because the default language of my OS is non-English), I get defaulted to amazon for a different country (and the Wikipedia for that language).

How do I get the US / international version as default?

Got to be kidding. The Firefox tutorial is the pits. The worst I seen yet. Is there a developers Firefox manual to be had, because the browser educational platform is the just the worst I seen in years?

The Firefox Container Add-on loads all Firefox Container tabs when starting Firefox. This really slows down everything. I always get the "A web page is slowing down your browser. What would you like to do." yellow bar and the whole page is not working. How can I prevent all these Firefox Container tabs from loading at startup?

Thanks!
