can't install Firefox browser extension "connection error"

Hello,

F-Secure, usually, will install extension/add-on automatically.

Did you mean that your experience about manual try to install extension-file to Firefox? And does it Windows platform?

If yes -> does it possible to re-check experience with built-in F-Secure 'reinstallation addon'-functionality.

Or your experience about autoinstallation addon by F-Secure?

Also, otherwise, maybe some Firefox tweaks are needed (for allowing manual installation).

Thanks!

Hello,

So, sorry for my reply. I'm also only F-Secure user (their home solutions). And I'm not really friendly with Mac-platform and F-Secure design on Mac platform.

Based on this Online Documentation:

https://help.f-secure.com/product.html#home/safe-mac/latest/en/task_2D2B7443B9A94482B64630E42949EF68-safe-mac-latest-en

There is button ''Install browser extension''. So, does your experience about such button and next FIrefox's notification?

If yes -> maybe it is possible to re-check such Firefox discussions:

• https://support.mozilla.org/questions/855759
• https://support.mozilla.org/questions/1050977

where was different 'sort'-steps. at least, it sounds as global design for Firefox -> and maybe can be useful to re-check with your situation

// I found that noted articles were about 'downloaded' (but not 'installed').

So, maybe if normal F-Secure design does not work. Maybe -> possible to find under your system '.xpi'-file (if it is existed) as F-Secure Browsing Protection addon. And re-try to add it manually to Firefox (like drag'n'drop, for example). Just like another suggestion -> some software/tool will prevent installation addon each time when you tried so.

An option is contact direct F-Secure Support Channels (chat as example):

Sorry for my long reply (and some edititions).

Thanks!
