Les plugins ont disparu et il est impossible de reinstaller des plugins. J'ai reinstallé Firefox, sans succès. Lors de la tentative d'installation de n'umporte quel plugin le message d'échec de téléchargement s'affiche. Les plugins ont aussi disparu sur le deuxième pc. Plugins comme Ghostery, Ublock, Fsecure, Duckduckgo.

Hi Saleve, I'm sorry you have this problem. It is not your connection; it is everyone's connection.

A critical Add-on-related certificate expired (which obviously should not happen). As a result, all verifications for that certificate are failing, preventing many extensions from being used, updated, or installed.

The Add-ons team is working on a fix for this. Official updates are expected to be posted here:

https://discourse.mozilla.org/t/certificate-issue-causing-add-ons-to-be-disabled-or-fail-to-install/39047

Currently, the only workaround is to set your system clock back (for example, if your date is May 3, set to May 2; if your date is May 4, set to May 3). You might have to reinstall extensions after that, or maybe Firefox will detect the difference at your next shut down/restart. Changing the date may have other consequences, so I understand this option isn't ideal.

Hi PatricarBel, your Firefox might have created a new profile. A new profile looks like a fresh installation without any of your data (bookmarks, saved logins, etc.).

If you haven't already, could you close out of Firefox and do a normal system shutdown and restart to complete any pending updates and release any file locks.

If Firefox again starts up without your data, could you check whether your stuff is available in a different profile, as follows:

If that does not help, and you prefer to communicate in French, you could consider using the following forum for further assistance:
