I updated to Firefox 84 on my macOS Catalina 10.15.7 system. At the end of the update process to Firefox 84, when Firefox restarted, a pop-up appeared that some files where suspected to be ransomware. I choose some "quarantine" button, but then the restart stopped and macOS showed a notification "The program "Firefox.app" cannot be opened" (My translation from german).

This message appears if I try to start Firefox from Finder or from Dock. Launching Firefox from the Profile Manager (via Terminal) works. Firefox is executed with my profile.

The following actions I took were not helpful: - Re-installing the Firefox-App and my profile from a Time Machine backup - Un-installing and re-installing Firefox from the Mozilla site. - Starting Firefox with a freshly created profile - Re-installing Catalina from macOS recovery mode

In the system preferences' security tab Firefox is not considered as beeing harmful.

I'd be very grateful for some hints where to look for further actions. Thanks, Ingo

new print preview window

My TWO questions concern this web page: https://support.mozilla.org/en-US/kb/how-print-web-pages-firefox

1) The web page mentions a new print menu in Firefox version 82. I have version 84.02 installed. The web page above shows "this improved print menu" under the heading "Print a web page." PLEASE NOTE: the "improved print menu" shown does NOT have a Simplify Page option. That option was on the old print menu. What happened to the Simplify Page option?

2) I have tried the "alternative instructions" shown on the web page above but that alternative does NOT give me the old "Print preview settings" shown. Instead, carefully following the "alternative instructions" gives me the same "improved print menu" mentioned above. Why does following the "alternative instructions" give me the new print menu and not the old print menu (which DOES have the Simplify Page option)?

Thank you.

Hi all,

Currently running Firefox 3.5.5 on Ubuntu Netbook Remix 9.04

Have not been able to find a way to update to an even slightly newer version of the Firefox browser. Upgrading the OS to a supported Linux distribution is impossible with this device.

With this, what can be done to improve the browsing experience of the currently installed Firefox version, 3.5.5? 90% of websites are inaccessible due to SSL_ERROR_NO_CYPHER_OVERLAP, and the sites that do connect will have breakages.

Thanks

Using current Firefox (84.0.2) on an iMac desk computer. Since Apple put out their recent upgrade to OS Big Sur (2019 ~Nov?), Firefox keeps dropping its internet connection. Works for a session, but when I come back a few hours later I see "Unable to connect..." Restarting always gets it back to start another session. But rebooting several times every day gets old. When Firefox is on the blink, Safari browser works fine, no problem. Connection is there. But my fullest set of bookmarks is in Firefox, so I'd rather use Firefox. Even more strange: Safari and Firefox both continue to work on my wife's desktop same iMac, no problem, just not Firefox on mine. Found help article "Firefox can't load websites but other browsers can" (https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can), went through every step to troubleshoot. No go, still drops. Contacted Apple support and they were flummoxed. Any ideas?

Bug 513418 suggests that private browsing windows are meant to use a dark theme, like Chrome, but this doesn't appear to be the case. Without this it's hard for me to quickly tell the difference between a normal window and a private window.

Is this an intentional change, or is a bug preventing private windows from using a dark theme?

In Wordpress, the editor tool menu at the top of the screen normally sticks to the top of the page. But in Firefox, it will disappear or scroll up with the rest of the page. This is not supposed to happen and doesn't in any other browser we've tested.

Resizing and refreshing the page may temporarily work, but the problem returns.

I have FF on Linux laptop and connected to my FF account to sync. All works fine. However after closing down laptop, restarting, open FF I do not auto reconnect to FF account and sync. What settings do I need so that I auto sync when opening FF? I DO NOT want FF to save site passwords i.e. BBC, TED, etc.

FF 84.0.2(64bit) for Linux Mint - 1.0

This is being sent / monitored from a Windows 10 computer and not the Linux laptop

Not sure if part of this posted as had an internet issue previously that took some time to resolve.

Hello

There is a website that won't go off my URL bar suggestion. I have tried everything I came across searching about this problem : - choosing the entry with the arrows and clicking on the DELETE button (holding SHIFT or not) - removing the website from my history - clicking on "forget this website" in the history - some other things I don't exactly remember

None of this has worked... The website isn't even bookmarked ! When I type "rs" on the search bar, I want rs-online.com and not rs-particuliers.com to appear. You can see the problem is this video : https://youtu.be/Vq5dUpkf534

This is driving me crazy... I use this website (rs-online) every day, and I never use the other one... I want it to get OFF my computer... Sorry if this isn't the right place !! Ask me anything you need to know !

Have a great day

I'm using Mac OS Big Sur and my setup has an external display. When using any other application on my mac, I can use Window > Move to <display name> to move windows to my external display and back. Because I can map a keyboard shortcut to this function, I use this all the time to move my windows around so I don't have to take my hands off my keyboard.

Firefox however seems to be the only application that doesn't implement this for some reason. Has any other Mac user found a way around this?

Hello. I am the user of Firefox browser. My main browser is firefox for recent years. I've been using it very well. I am very satisfied with the customization of Firefox. But today, Firefox stop several times when i use youtube and google. Some youtube videos are not start, and scroll is stop end Firefox says "No response" when i am searching in google. Some of the youtube didn't run at Firefox, so I played them in Chrome and it worked well. And it was not an Internet problem. Because other online programs such as messenger worked well. I bought a new desktop and formatted it a month ago, and I installed the latest versions of Windows and Firefox. This is why I think Firefox is a problem. Please check why Firefox stop today. Thank you.

Before when using Firefox, if I wanted to print, I could select - from the File drop down menu - either Print or Print Preview. Now Print Preview seems to have disappeared! All I get is Print and then a selection menu makes me manually select custom to list the page or pages I want, and then select the size of the printed page - all VERY inconvenient and VERY difficult to use. What happened? Was that an update to Firefox recently. If so, VERY poor decision and programmer that decided on this change should be fired.
