Firefox 도움말 포럼

When attempting to play some videos with Firefox browser, mainly from X (Twitter) I receive "This video can't be played." However, I can't play them with Safari either. But it will play on Safari on another computer. I don't know what is wrong. Could it be some settings on my computer? I'm not a computer ace but know some things. Thank You for any help/ advice.

Hi, HELP!! My browser keeps crashing on sites that I use on a daily. I use office 365 outlook, and teams. Its been getting worse and worse like crashes every 15-20 mins. I've sent the reports but I have not see a patch to fix the issues. Please help otherwise I have to go to another browser.

Here are the links to the sites I work online that keep crashing on the Firefox browser: https://acu.empirepro.com/AcumaticaERP/Frames/Login.aspx?ReturnUrl=%2fAcumaticaERP%2f https://outlook.office365.com/mail/inbox https://teams.microsoft.com/_#/conversations/19:175319c1-ef69-4f40-a21d-173c9a0afbad_8a69628f-f70f-4696-ae5e-430740483a19@unq.gbl.spaces?ctx=chat

Recently I got a Mac computer and I installed Firefox in it. I can't find "About Firefox" in Application Menu.

How to show it in Application Menu like Windows and Linux?

I am writing you using Safari. When I click on the Firefox icon in the dock, "Fiirefox" does not appear in the menu bar, instead I keep getting the same message window, "The application "Firefox" can't be opened."

I am using an iMac, OS 10.15.7. This problem just started today after using Firefox for years

I have Firefox 100.0.1 on my Mac desktop, and Firefox 100.0 on my MacBook Pro laptop. I can no longer access my Microsoft OneDrive account via the web on my desktop, but I still can do so on my laptop. I have gone through your posted troubleshooting steps for Firefox on my desktop, to no avail. How do I get my desktop back to version 100.0 so it will work again? I can access my OneDrive account via the web on my desktop when I use the Safari browser, so the issue is definitely with Firefox version 100.0.1, and not with my desktop.

Since updating, "Exit Full Screen" now causes viewed page to become a narrow sliver at the top of the screen, and the page unusable. I typically drag pictures from my desktop to Facebook, etc., but can no longer do that. (I know there is another way to access pictures from the desktop, but it is currently unreliable on my machine, which is very slow and wonky right now.) Can I revert to the former function where "Exit Full Screen" just makes the page smaller but still usable?

I am trying to remove old unused primary email and change to new My old email which I have NO ACCESS TO is [email address] My new email is: [email address] Please email me at the icloud account THANK YOU!!!!!!

Suddenly, when I search the web with a topic search term, e.g. "thrombin", I get the error message: 'The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.' Can you help me resolve this problem?

Hello! We distribute Firefox add-ons on PC and macOS outside of Mozilla store.

Until Firefox 100.0 our users were able to install the add-on by clicking a button on the product side which was opening a link to XPI file hosted on our company's download server. That was triggering a usual install dialog from Firefox where it asks user to confirm the installation.

Starting from Firefox 100.0 this stopped happening and we started receiving numerous support calls from our customers about not being able to install the add-on. The issue now is that when the XPI link is opened in Firefox, the install dialog does not appear which brings a lot of confusion to the user. Firefox shows the link to the XPI in the address bar but does not start the usual install process (attaching screenshot of how it looks like on my Mac). The issue applies to both macOS and Windows platforms. I've opened a bug case on bugzilla. The link for reference: https://bugzilla.mozilla.org/show_bug.cgi?id=1766965

Could someone please clarify how we should proceed with this issue? We are now getting reports of this issue from many of our customers. Thank you.
