Firefox Community Forum

Hello- Am having trouble with my settings( I think) Want to be sure Firefox is default browser, and use Adobe Reader as my PDF default. All I get is "download Firefox" ! Get all regular updates, so why can't I see "settings" ? Thank you

I want to import my Chrome bookmarks into Firefox but I keep getting asked for my keychain password. I've tried my Apple I’d password and my Firefox account password. Neither works.

Sehr geehrtes Support-Team,

ich habe seit Kurzem ein Problem mit Firefox auf meinem PC. Es erscheint folgende Fehlermeldung:

   „Das Lesezeichen- und Chronik-System wird nicht funktionieren, da eine der Dateien von Firefox von einer anderen Anwendung verwendet wird. Dieses Problem könnte von einer Sicherheitssoftware verursacht werden, beispielsweise von einem Virenscanner.“

Ich nutze dasselbe Firefox-Konto auf meinem Handy und auf meinem iPad. Dort funktioniert die Synchronisierung der Lesezeichen ohne Probleme. Das Problem tritt nur auf meinem PC auf.

Ich arbeite bereits seit mehreren Jahren mit Firefox und hatte dieses Problem bisher noch nie. In meinen Lesezeichen sind sehr viele wichtige Webseiten gespeichert, deshalb möchte ich diese auf keinen Fall verlieren.

Können Sie mir bitte mitteilen, wie ich dieses Problem beheben kann, ohne dass meine Lesezeichen verloren gehen?

Vielen Dank für Ihre Unterstützung.

Mit freundlichen Grüßen

Meik

I can't open, delete, uninstall or update my Firefox on my laptop???

I dont have much Ram space on my computer - but am working on expanding it.

Yet, still - I can't open, delete, uninstall or update my Firefox on my laptop

I have this VPN from Switzerland that is stealing my information I have no idea how it got there on Google. I have tried to remove it but can't figure it out. Can you help me please

I opened Firefox this morning and there were no bookmarks or history. After looking online, I came to the conclusion that I needed to find the places.sqlite and bookmarkbackups files and folders. However, I can't seem to locate either.

I am running Firefox v153.0 (aarch64) on Mac OS v. 26.5.2

I have Time machine backups, but I need help locating the correct files to restore. Thank you.

Using the Firefox 151.0 Mozilla Firefox for Fedora. Updated as of 23 May 2026, I use just a generic FireFox. I don't customize it, I just use it as it comes from the Fedora distribution.

I cannot save images (right click menu "Save Image As"). Nothing happens when that is selected. This worked a couple weeks ago.

Downloads are supposed to go to ~/Downloads. Checking the setting for this, Go to the three-line menu > Settings > General > Files and Applications, under Downloads, the "Save files to" value is set to Downloads, but the Browse button does not work to reset it. Nothing happens when I poke on the button. I can select the text in the box, but I can't change it.

I found the help page for "What to do if you can't download or save files https://support.mozilla.org/en-US/kb/cant-download-or-save-files and went thru every one of the steps there. None of them make any difference.

Strangely enough, there isn't even a "Downloads button" in the top toolbar. If I right click on the top toolbar and select "Customize Toolbar" it shows a downloads icon as already being in the toolbar, but when I click Done, it goes away.
