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.

Hello: Passwords from CSV file: "firefox logins.csv" does NOT show up in the "Import Browser Data" box? I reinstalled a fresh copy of Windows7 and firefox (Firefox Setup 115.14.0esr.exe). I'm unable to import my "Passwords from CSV file" because it is not included in the "Import Browser Data" box (see Attachments (pics). Note: I do not use the Browser in this picture only firefox. How than can I import this .csv file? Regards -mdc

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.

Hi, I want to use dark background color theme in the Mozilla Firefox PDF viewer, read here https://support.mozilla.org/en-US/questions/1434510 but cannot find "userContent.css". My question is where can I find this file on a Windows 7 or Windows 10 installation?

Starting today, amazon web pages are not updating correctly. The amazon web page appears normal till I sign in, then it doesn't update "cart" contents or show account holders name or list any "Lists" when accessing account saved lists. I have deleted entire history, and all cookies and caches X 3. I Rebooted computer along with a "system command control reset" and still the pages are not loading correctly. Short of reinstalling "Firefox" what more can I do? Are there any "Preference" files or files with specific extensions I can delete? Thank you. Gerard

Browser is not letting me choose the airports on Breeze Airways. No issues with using Safari. Also, American Airlines is sometimes spotty using FF, not loading the main page.

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.

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

The "search in page" feature has somehow become hidden behind the taskbar at the bottom of my screen. I can only see it by using F11 to hide the taskbar. Any ideas on making it visible again?
