It's probably a security setting...for some websites I go to Log In and nothing happens. Same for say signing up for a webinar. 80% of the time now Especially if I'm following a clicked eMail...so most likely a tracker of sorts?? ChatGPT not helping...wants me to do some techy stuff.

Trouble Shooting Mode, turning off ETP off for site AND in Exclusions... In Chrome, no problem.

Running Malwarebytes and Kaspersky

I'm hoping someone else has solved this!

Thanks

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!

I know the sites are secure (unless something is happening that I don't know about). I just want to get onto them, especially the Christmas site. Is it to do with Bitdefender?? I hope someone can help as the letter I want to write is getting time sensitive.

After instalation Eset Smart Security 18.2.18.0 with full security browsers my Firefox is run only in read-only mode. If I will be disable option Security browser and run Firefox that's working. Next I will be enable option Security browser then Firefox starts with green frame. After close Firefox and next run then starts read-only mode. Eset Team is not fair play becouse resolving problem only disable option Security browser. So why is there an option that prevents Firefox from launching? All my portable browsers without Eset Security working without any kind of problems, for example Tor, Opera.

Like many, I have Windows 10 and cannot upgrade to Windows 11 without purchasing a new computer. I don't want the upgrade as my desktop computing needs are simple -- checking email and occasional online research. I am looking at 0patch as a solution to Microsoft discontinuing support for Windows 10 and want to know if Firefox will operate compatibly with 0patch providing security patches instead of Microsoft.

I'm not a technical person, so please keep replies simple. At 80 it's tough to keep up with all the changes! Thanks.
