Φόρουμ υποστήριξης - Firefox

I've recently had a little video window appear in the bottom right corner of my browser screen. I can't find any control link to eliminate it other than closing it manually every time it appears. Where did it come from and how do I get rid of it?

Suddenly on my PC the icon of Firefox turned white on both desktop and taskbar. And whenever I try to open Firefox, it says, "The file or directory is corrupted and unreadable." And I didn't make any changes myself. So far it was fine. Now what can/should I do?

When choosing biometrics for 2-factor authentication, sometimes Firefox will only prompt for a physical hardware key, and Touch ID does not work. Support for built-in biometrics is inconsistent.

For reference, I am using Mac OS Sonoma 14.4.1 with an ARM processor.

Sorry, posted recently and had then trouble finding out how to respond to help offered (jscher2000)! Noticed that the email version was "no-reply" so I didn't figure that would work! So, I tried to 'cut and paste' my reply (on a smartphone) and I ended up losing even the email reply text so here is a reconstruction. I tried the suggestions in order and the first one didn't have a "Restore previous session" option and the second one had "Recently closed windows" greyed out! And, when I entered "about.support" in the address bar (top rightish), I received a notice that I couldn't reach Google (Remember that I don't currently have internet access on my laptop). So, no joy there either! Can I not just change some current setting to prevent Firefox v 115.9lesr from saving the current 'Windows' and Tabs so that, when I again open Firefox, the previous session 'Windows' and Tabs would be used?!?

Issue summary: I lost over 100 sites listed in the Cookies and Site Data section when I simply removed a few websites in the Enhanced Tracking Protection section.

Under the Browser Privacy section, the two subheads, "Enhanced Tracking Protection" and "Cookies and Site Data" serve two distinct purposes—as I understand. Enhanced Tracking Protection will automatically add the URL of a webpage (that you currently have open) to the Enhanced Tracking Protection screen whenever you disable the shield in the search bar. This will turn off tracking for that website until turn you it back on. You can also manually add websites to the Enhanced Tracking Protection screen if you have mulitples to add. This whitelist will stay active until you delete them or click on the shield to turn it back on.

The Cookies and Site Data section further down, allows you to create a list of sites that you want to BLOCK, ALLOW FOR SESSION, or ALLOW cookies and site data to be used, and retained or not. This differs from the Enhanced Tracking Protection section.

Today, I wanted to delete one of the websites listed in the Enhanced Tracking Protection, and did so manually. But since there were only a couple listed (I rarely add to this screen), I simply clicked on "Remove All Websites" instead of "Remove Website." Unfortunately, when I went down to the Cookies and Site Data list (which I use all the time) to add a new URL today, my entire list was gone! I did not remove or enter anything in the Cookies and Site Data screen today, prior to using the Enhanced Tracking Protection screen.

As you can guess, I am sick because I had over 100 sites listed in the Cookies and Site Data section, and lost them all when I removed the few websites in the Enhanced Tracking Protection section. I don't know why or how this happened, but it is worth noting that I did just update Firefox this morning to vs 125.0.2 (from 124.0.2). My list is gone, but does anyone have a reason why it happened and is there a way to prevent that in the future? Or is it some kind of bug with the latest release or an earlier one. (I haven't opened the Enhanced Tracking Protection screen for a long time, so it could be from any past release.) Sorry I don't have more info than that. Any solutions would be appeciated.

Unable to run firefox. I get the error message. (see attached screenshot) After terminating firefox processes, I attempted to create a new profile. and see an error message. (see attached screenshot)

Most of the time I cannot print my emails because an "add blocker" is installed. So now, I no longer use Firefox, since when I use Microsoft, I have no such problem.

in the firefox browser is there any way to see the casting the browser screen to chromecast on tv. similar to 'cast to media device' in edge browser or chrome browser.

I get the following message when going online with Firefox: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I've followed all the prompts to restart the computer, refresh the computer, delete the favicons.sqlite and places.sqlite and it won't allow me to delete them. This happened yesterday as well. Yesterday I could delete those files and everything was restored. But today I can't get it to work.

why can't I use the lingq importer extention? I get a message for all my extentions that says: firefox extension can't read and change data on this site. It's preventing me from using the LingQ importer extention.

For several sites, when i check 'trust this device' it doesn't work. next time i signin it still requires 2fa from the site. i've checked and the certificates do exist as i get a message saying already exists when i try to import. this is a very user hostile function. I do not have this issue with Chrome or Microsoft Edge!!!!! i hate to begin using one of these vs Mozilla Firefox to get around this but i may have to do so. my wife and i share access to critical sites so if i need to see her info or she needs to see mine, we both have to be available in order to access the site. Mozilla Firefox 'bug' is requiring us to do so and it doesn't satisfy our requirements. any ways to solve this issue is greatly appreciated. so far no 'searched' solutions work.

This started a few weeks ago. I thought it might have been because I synced the passwords with other devices. I reverted it back.

When in about:logins, I click on the log in button but nothing happens.

Thank you for your assistance in advance. Since I updated my browser, I've encountered some issues when trying to maximize the virtual screen in my tv. I use a Mac and connect the screen to a web TV to watch YouTube in my big tv. However, when I click to maximize the window, the connection becomes unstable, and the virtual screen disappears every time I click the YouTube icon to do this. This problem never occurred before. I would appreciate your help in resolving this issue. Please let me know if you require any additional information from me.

I received a scam Apple (security) popup (on which I never clicked) and from that point on, some 30+ obsolete tabs congregate across the top Firefox browser window. How do i lose all these unwanted tabs?

I currently have a 'bad/rouge' session of Windows 7 Firefox (don't really know how that happened) open (7 'Windows', each with one empty Tab plus 1 'Window', with only 1 populated tab (Yahoo Mail)! I need to close Firefox in order to restart my laptop (strange things have been happening, including not being able to access the internet)!! On restarting, I want to be able to open Firefox with the previous session I had with my 8 'Windows', each with dozens and dozens of Tabs! Please help, I sorely need those many 'Windows' and Tabs!!!

Firefox slows down when I use web developer tools, I use this whenever I try to save an image on Instagram or other sites that I go to just to save an image or look for the video using the web tools.

Is there a way to fix this issue it lags the browser or it freezes for a second.

Whenever I select tab and then start typing in the page search box it automatically jumps to the URL/Address bar. This is not only annoying but it makes it difficult for me to see what I'm typing, and it often results in unwanted typing errors. I have yet to encounter a single longtime Firefox user who thinks this is a good idea, but I have met several who've decided to drop Firefox and start using Chrome just to be done with it. I've been using Firefox since early 2005 and I've mostly been happy with it but this is just to annoying to continue. I'm complaining because the feature exits, I'm complaining because there's no option to opt for those of us who find it annoying and will never become comfortable with it.

If there is a working fix that I've been unable to find, then please point me to where or what it is so that I can apply it.
