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?

Hi, I'm hoping to find some help to address crashing that has been happening frequently. The most recent crash has a report ID: bp-47617fc8-55f9-4d32-8713-a4ce40240426 and this happened while in 'troubleshoot' mode.

This is the link to that report: https://crash-stats.mozilla.org/report/index/47617fc8-55f9-4d32-8713-a4ce40240426

Any help in finding a fix would be appreciated. Sincere thanks, V

Every once in a while, maybe once or twice a week, I'll press Cmd+L to highlight the address bar, type a URL for a new website, and press enter, and instead of going to that new website Firefox just reloads the current page. It seems that this happens exclusively when the current website is gmail.com. (I might be wrong) I can't remember it happening on any other website. This problem has been occurring for me for the past year at least. Any recommendations?

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.

I am using Firefox v125.0.2. When I open a PDF in Firefox it takes a lot of time to load. But, when the same PDF opened in the Edge browser it loads normally and scrolling through PDF pages renders fast. I have shared the screenshot of a single-page pdf loading taking quite a long time.

Could someone please help me with this.

I am unable to login to the DVLC. I get as far as the enter reg number of a car to check it,s been taxed. Then after I input the reg number the next page tell me it is an insecure page. This also happens on my laptop. On both desktop and laptop I am using firefox with duck duck go as an add on. However. In using my mobile with the stand alone duck duck go browser, I can log in and complete the task. This points to a problem with Firefox. Any advice's. This seems to be recent as I have used the laptop and desktop to use the check for a taxed car system ok in the past.

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)

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?

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.

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!!!
