Firefox Community Forum

I just updated my iMac from Mojave to Catalina 10.15.7. I thought Firefox would provide an update to convert the esr version to the standard Firefox browser since I am no longer using Mojave, but the next update is 115.15.0esr. Is that correct? My understanding is that the esr updates are just for computers using older operating systems through Mojave. I did not update to 115.15.0esr since I am not sure if that is the right version for Catalina. Any information and assistance you can provide me is greatly appreciated. Thank you.

Today, it started.

When I open sites that I am subscribed to, a small gray-shaded nearly transparent rectangular window appears in the upper right of the screen (see attached screen capture), and it blocks access to login and search, thus rendering the site inoperable. The latest site rendered inoperable is Amazon shopping, so this is not a minor thing. I can no longer retain Firefox as my default browser.

No other browser on my Mac does this; the earlier version of Firefox active last night did not do so either. What is the purpose of this gray-shaded window? It makes the latest browser appear to be infected with malware.

Running OSX 10.13.6 on a mid 2012 Macbook Pro.

Firefox will not allow me to login to my mail a/c which I have had for more than 20 years. Because of this I cannot access a code to access my MS Outlook a/c This message shows:

'Firefox detected a potential security threat and did not continue to webmail.mercuryin.es. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.' AND tells me that there is nothing I can do about this.

Ever since Facebook started infesting the chats with end-to-end encryption (random chats get "Messenger upgraded the security of this chat. Messages and calls are secured with end-to-end encryption" without my permission or asking if I want this), any encrypted chats have audio and video calls disabled. I note that I have ONE friend for whom it didn't do this, I can still do calls with her. If I receive a call, I get a pop-up saying that to receive this call I must download the Messenger app (no way) or a browser which supports it. If I check what browsers it thinks supports this, it only lists Chrome and Edge. As far as I know Edge is just Internet Explorer renamed, the biggest black hole in security, I've never touched it. Chrome ignores industry standards, so I don't use it. Making Firefox the best, top browser available. It's the only browser I wish to use. Mozilla needs to look into how to get Facebook to stop blacklisting Firefox like this. Note that this E2EE garbage has only been infecting things for the last few months, before that I was perfectly able to do any calls I wished in Facebook Messenger.

Up until the latest Firefox Nightly release, I could click on the '+' to open a new tab and immediately start typing the URL. Now, however, I am required to select a container type, something that is useless to me. Is there a way to disable this?

UPDATE: Never mind, I found the setting for Enable Container Tabs, which needs to be deselected. Why is this an opt-out?

If a moderator wants to delete this post, go for it.

Can't pinpoint the date, but a while back Youtube won't play videos anymore. It just shows a black screen in the player. Not even the player UI (pause button, volume, settings menu) shows. Just a black portion of the screen. Now when I went in to get a screenshot, it doesn't even show the black box.

Hello

Last week I deleted my browsing history, I had don't so since 2023, sadly I just found out that I need to restore a number of those close pages, I found the same topic on the site however it's from 2020 :

1. Click "Start" > "Search" > "Tools" > "Folder Options." 2. Click "View" > select "Show hidden files and folders" > uncheck "Hide extensions for known file types" and "Hide protected operating system files". 3. Click search in "All Files and Folders" in the C Drive > type index.dat in search bar > click "Search". 4. Download and install index.dat file reader on your PC if you don't have one. 5. Open index.dat file within the reader > Click on the Firefox browsing history you want to restore > Click "Restore". Then you can open your Firefox browser to check all your restored history now.

I followed the above steps until nr 5, it does not show me any data on firefox

Secure connection cannot be established

When a website that requires a secure (HTTPS) connection tries to secure communication with your computer, Firefox cross-checks this attempt to make sure that the website certificate and the connection method are actually secure. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. Secure Connection Failed

A Secure Connection Failed error page will include a description of the error and a Try Again button. There is no option to add a security exception to bypass this type of error.
