Firefox Community Forum

out of nowhere my firefox bookmarks no longer appear. I am getting the following msg

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.

In an attempt to fix this problem, I have done the following:

• closed the browser and re-opened it
• rebooted my computer
• reinstalled my security software
• uninstalled firefox
• Reinstalled firefox

None of these steps have fixed the problem??????

Any ideas would be appreciated!

When I was trying to sing in to bit defender I ended up wiht this mozilla package. why did the bit defender have a statement questioning reliability using an ad-on?

I recently re-installed FireFox after I suddenly had problems that the profile folder could not be accessed. I uninstalled it, then reinstalled it using the download from Mozilla website. This fixed the profile issue. I am using the latest version. Now, I find that most of the time, cnn.com won't load: I see messages on the bottom left corner that it is connecting to all sorts of web sites, in particular it tends to get stuck on "Sending request to signal-metrics-collector-beta.s-onetag.com" . I don't know if it eventually loads, I give up after about 1 minute. In Chrome, cnn.com loads instantly. In Firefox, BBC.com loads instantly. Microsoft.com loads instantly. I have installed the same extensions as before. I started FireFox with all of them turned off, no difference. As I mentioned, it does not load MOST of the time - once in a while it loads instantly, but later on the problem reoccurs. >What is wrong with FireFox and why won't it load CNN as quickly as before? I am using Firefox on Windows 11, I have Malwarebyes installed. Thanks, Adriaan

I got the following message while trying to access this website https://nubecomun.yanapak.org/ The connection has timed out:

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

How can I allow Firefox to access the site?

Pandora tries to start, but it bounces from artist to artist without playing. Never had this happen before. Pandora suggests there is an overzealous ad blocker at work. Can you help?

Hmm. We’re having trouble finding that site.

We can’t connect to the server at yourewardcard.com.

If you entered the right address, you can:

Der Community,

Sinne yesterday night my Firefox don't work anymore. The online thing i can get is this : bp-fa8b47ab-4fb5-42de-ae52-3a3620250817 I think this the Failurecode. I tried everything, like clean the Cash, set the Proxy to non use, the clean up Option everything. I deinstall it and install it new, but the Problems still exist. The only Change is the Failurecode. The new one is : 6f317949-b419-45cc-a9ea-27e0052ee481 Any other Browser also didn't work, like Edge or Opera. The start but doesn't load any Seite. Thanks for your Patience and time with me and my bad english. Steven from Germany

I am trying to set up a vpn using Proton as a Firefox add-in but Firefox won't let me use it, saying it has invalid credentials. I can't contact Proton because if I enable it as an add-in to Firefox, I can't use my browser. Do you know of any other vpn networks that work securely with Firefox?

I wrote yesterday but my post doesn't appear today. Today I got the message about bookmarks and history not functioning and eventually found something in Firefox that said it was probably due to "some security software." I have now gone into Windows settings and my security updates are done, but I have no idea what I'm supposed to do now. This is an extremely annoying and disruptive issue. I see that several other people are experiencing it, so it's interesting that the note next to their posts state that no one else is having the same problem. Can someone please help us all to get our bookmarks and history back?
