I got so frustrated with not being able to reinstall Firefox because I kept getting the error message "Your Firefox profile cannot be loaded. It may be missing or inaccessible". So I deleted all the profiles after copying them to an external hard drive. Then I copied the file ending in.test from the Old Firefox data folder on my desktop to the AppData/Roaming/Mozilla/Firefox/ profile. Then I copied the biggest file ending in .default from the backed up Local profiles to the AppData/Local/Mozilla/Firefox/ profile. It doesn't matter if I delete or keep the Old Firefox data folder on my desktop, I still get the Profile Missing error message. What can I do, so my laptop would appear as if it had been powered up straight out of the box and never had Firefox initially installed or what do I do with my profiles to make them accessible?

После недавнего обновления браузер перестал открывать сстраницы или открывает их очень медленно. Я очистил кеш, отключил производительность и ничего не помогает. Как решить это проблему? Пс. Хром работает отлично на этом же ПК.

Здравствуйте! При установке параметра "Настройки - Основные - Открывать Firefox автоматически при загрузке компьютера" в реестре создается запись HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run - Mozilla-Firefox-E385C0CFD98A494C: "путь-к-файлу\firefox.exe" -os-autostart Что за параметр командной строки -os-autostart? На на сайте поддержки Mozzila не нашел, ни интернет не подсказал. Я понимаю, что это автозапуск Firefox при запуске Windows. Но что конкретно делает данный параметр?

Best topic is covered by all of the options, unfortunately! If I have done anything incorrectly it was done thru lack of tech savvy for which I apologize for. I have to go take care of the horses now, thank you for any help you may have.

Bonjour, A l"allumage de mon ordinateur,ce matin, quand je clique sur l'icône "Firefox", une fenêtre sans mes onglets d'hier C'est une page m'invitant à télécharger Firefox. Je n'ai plus accès à mon historique et, n'ayant plus accès à mes mots de passe, j'ai du mal à ouvrir mes sites préférés. Merci par avance de votre aide. Annie Le Drévo

On my home screen, the visited sites are all crammed to one side, lower left, and all narrow in their appearance. I prefer they look as they did before, with the "tabs" or site boxes along the bottom of my regular sites. And I can't seem to "delete" the sites I visit; I can only dismiss them. And that often doesn't work as well either.

bold textI downloaded fire fox but don't see it listed with my other browsers, why? i downloaded fire fox but it's not listed among my browsers, why?

On last Firefox update my Password manager was blanked out. I had no username/passwords in my Password Manager although I had previously had over 100. I managed to recover it by logging in to my Mozilla account but now have access to over 7000 of other peoples usernames and passwords on my password manager. You seem to have a major data breech or is this a quirk I don't understand? These other names/passwords show up when I try to log into certain sites, such as Schwab for example, and I have to pick mine out of a host of others to fill in the login info. What is going on?

When I click on the star icon in the address bar the star icon is filled in, and existing bookmarks show with the filled-in star icon. But I no longer get a dropdown where I can edit, tag, or delete an existing bookmark, and URLs I click on don't show up in Recently Bookmarked so they haven't been added.

The places.sqlite file in my profile is not read-only, and I restarted Firefox (stupidly, before I took a screenshot of the pinned shortcuts on my new tabs page) and that made no difference.

Thanks in advance for any help!

Hi,

I searched the web for deleting the item "Weitere Lesezeichen" in the sidebar. I found only solutions for the firefox 85. In Firefox 85 should be a field for hiding this. Although in Firefox 150 it can`t be hided or deleted. I don`t need and I don`t want this "Weitere Lesezeichen". Any solutions?

I am on a new PC with Windows 11, using 4 monitors. I keep trying to figure out what is making my mouse and sometimes the keyboard behave sluggish (freezes for a moment). I have takes all suggestions that AI has suggested but it is still happening. Do you have any thing for me to try? It appears to be only when Firefox is running.

This has happened randomly on several different computers, both windows and ubuntu linux. It just now happened on my Win 11 computer. Was viewing the CNN news site and FF suddenly closed, without a "FF crashed..." message.When I clicked the icon to reopen it, it came up with the home page group of tabs instead of reopening the windows and tabs that were opened when it crashed. Worse, none of the previous months of history shows up and recently closed tabs and windows are both greyed out.

Is there a way of recovering the history of what I was working on at the time of the crash and what the hell is causing this? I am close to dumping FF and going with something else as this is highly annoying.
