Firefox Support Forum

Hello; I installed a new web page. While the page opens properly in browsers such as Safari and Chrome, in Firefox it constantly displays 403 forbidden Access to this resource on the server is denied! gives an error. I deleted the caches. I did flush DNS. I even reset firefox. I tried everything but the page still gives an error. There is only a dry WordPress content. How can I get rid of this error? Thanks.

Hi there,

I just started using my new MacBook Air, and when I try to use the trackpad to open read Gmail or click the calendar icon on Firefox, it doesn't respond. It works on Safari.

As per the photo, I try to click the calendar icon to open up my calendar and nothing happened.

I have been getting a message that says firefox has something running and cannot shut down. I went into task manager and 'shut down' firefox, but the message keeps on coming. I then thought that I would uninstall it and then reinstall, but it tells me that it cannot uninstall because it is running, -"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window." When I click on ' Close Firefox' nothing happens. when I click on 'Cancel' the message disappears, but will reappear. Then in desperation, I went into program files and deleted the Fifefox folders but it wouldn't reinstall. There is obviously somewhere a file/file which is screwing me up, does anyone know what this it?

I have a 2019 Macbook Pro 16" and whenever I share a FireFox window on facetime, I'm unable to stop sharing it until I end the Facetime call. Even then, the sharing screen notification still appears in the top right in the menu bar and I'm unable to share my screen for future Facetime calls unless I restart my laptop (thus removing the problem). Is this a known issue, and is there a way to fix it other than restarting my laptop?

It takes forever for my home page (MSN) to load when I first start Firefox. Can that process be speeded up? I suspect there's a way to get my home page to load faster. Can someone help? Thank you, Firefox.

Hi, first the last update tried a few times over some days to install. Never got confirmation that it has been installed successfully. When I go to "About Firefox" I'm getting the information that I'm using the latest version.

Now I have problems, mainly when using facebook (especially when I try to play games through facebook) that Firefox uses enormous amounts of CPU and Memory. This does not happen all the time but at least in 70% of tries. I attached 2 screenshots

If this happens I'm not able to close Firefox the normal way but have to kill the process in the task manager.

Any quick help would be appreciated. I would also like to know if I'm the only one experiencing this or if it's a common problem.
