Chosen solution

It has been 3 months, and the problem came back. Even disabling FDM did not stop it, so I did more digging.

I finally discovered the problem was caused by this file; C:\Users\===user===\AppData\Roaming\Mozilla\Firefox\ Profiles\===profile===\extensions\ {93d91d5e-1272-42e3-8323-a830fe339ac5}.xpi

Removing this solved the problem. I did a web search using many engines, but could not find any information on this file.

Thanks again to everyone that tried to help.

Please update to Firefox 61.0.2. Firefox 54 is no longer supported.

Then, what extension are you trying to install? Please give some more context if you still see this issue.

Hi FredMcD, extensions built on the WebExtensions APIs have much more restricted access to your system than legacy extensions. To read/write areas of the hard drive outside of extension storage, or to execute functions of companion software, an extension author may distribute a program that needs to be downloaded and installed separately from the extension. These separate programs do not get any review by the Add-ons team, so you should only install such programs from developers you trust and with a good understanding of what they do, as you would with any other applications you install on your system.

After an hour, Malwarebytes showed me a list of Pup's and I quarantined them. But the issue remains.

However, I found the cause. It's the program; Free Download Manager. Disabling this removed the problem. I will have to contact its support.

Chosen Solution

It has been 3 months, and the problem came back. Even disabling FDM did not stop it, so I did more digging.

I finally discovered the problem was caused by this file; C:\Users\===user===\AppData\Roaming\Mozilla\Firefox\ Profiles\===profile===\extensions\ {93d91d5e-1272-42e3-8323-a830fe339ac5}.xpi

Removing this solved the problem. I did a web search using many engines, but could not find any information on this file.

Hi FredMcD, as you may know, a .xpi file has the structure of a .zip file. If you rename it from .xpi to .zip, you can look inside and see whether it has a manifest.json file at the top level of the archive, which usually indicates it was built using the WebExtensions technology. An install.rdf file typically indicates a legacy extension.
