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?

I have some names that pop up in an autofill dropdown when trying to input names. Some of them are misspelled and some are obsolete. How do i delete these? I've looked in Privacy and Settings and they are NOT present under "Addresses and more". Those are complete addresses with names. The ones i'm referring to are just names that pop up in an autofill drop down. These are names that i can't seem to find anywhere in Settings.

I came across another thread here that said try highlighting the name and Shift+Fn+Delete. This does not work

Thanks in advance.

I have two profiles, one for work and one for my personal in the same account. I need to sync both of my profiles but do not want the information in the two profiles mixed together. I need to sync the information as I have a desktop and a laptop that I use for work, and mobile devices and another laptop for personal matters. If I am on work travel and need to access my personal profile on my laptop (because schlepping two machines is silly!), I want to switch my profile to the personal one. then when I am done I want to switch back to the work profile. How can I do this and is firefox set up to do this?

Firefox dropdowns, menus and popup menus do not appear after resume from suspend on Ubuntu 22 or 24 This has been happening for only the last few weeks. Even dropdowns on web pages do not appear. I can click the dropdown and cursor down then hit ENTER to change a dropdown's value but I cannot see anything while I'm doing it. On the menus, I can use hotkeys if I remember them but the menus themselves do not appear. Right-clicking to get a context menu also does nothing but it behaves like it did. If I right click something, nothing changes on screen but if I then click another link or button, the first click is swallowed to dismiss the non-existent popup.

Other apps on the system work fine including Chromium browser.

This only occurs if I start Firefox then suspend the machine and then resume from suspend. After resume, the menus, dropdowns and popups no longer appear.

I am running Ubuntu 24.04.4 LTS on a Dell Optiplex 3050, Core i3-7100x4 , 16 GB ram, Intel HD graphics 630 (KBL GT2), Gnome 46, Wayland windowing system.

I tried Firefox safe mode, clearing the caches, etc. Nothing worked.

Using firefox 140.6.0esr on Windows 10 with noScript and uBlock Origin

Infrastructure for my health insurance provider website uses a self-signed certificate. The infra has a different URL from the main page and was initially failing with "CORS failed", which turned out to be the cert issue.

I copied the infra URL from the dev tools network log and opened it directly, and accepted the invalid cert. I can see the new exception in cert_override.txt.

Then, after unblocking the site in uBlock origin, POST and GET requests to the infra URL succeed, but OPTIONS requests are still failing with "CORS failed", and security status "SEC_ERROR_UNKNOWN_ISSUER"

Is there anything else I can do so the OPTIONS request honors the exception in cert_override.txt?

I'm unable to download any of my Intel updates. I've turned everything off that I know could be blocking it and authorized Intel as a safe download. I don't know what else I can do please help. Google states that I should be able to go to the shield and the address bar and turn off the enhanced tracking protection however it will not allow. I've gone to the settings page and set it to custom as well as clear all check marks in that setting. Still nothing will not allow me to download my updates for my Intel drivers. Please help

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.

I submitted a bug last to Bugzilla last Sep. that seems not yet to be assigned to anyone, and a bug two days ago that wasn't acknowledged. Is the Bugzilla site working? Should I be doing something else to report the bug?

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.

Before the update, I could use "cmd+shift+[number]" to open a new container tab. Now, nothing works. "cmd+t" opens a tab with "no container", which is completely different.

I already tried going to "about:keyboard", but opening a new container tab isn't even listed as an option.
