How to fix the broken version of the Plug-in

Lately, Lastpass has occasionally struggled with the add-on. The currently version (4.9.2) for Firefox is broken. You need to roll back to version 4.9.1.1 and things will work as expected. See this forum post: https://forums.lastpass.com/viewtopic.php?f=12&t=299455&start=30#p999975

For those complaining about the loss of functionality compared to the older versions (ability to easily copy passwords/usernames), you need to install the "Binary Component" which is NOT part of the new plugin but can easily be installed. See: https://lastpass.com/support.php?cmd=showfaq&id=5576

Installation of the binary component is required for the copy username/password features.

Kindly try if the following helps:
1. Uninstall LP on Firefox https://lastpass.com/support.php?cmd=showfaq&id=185
2. Clear Firefox's cache and cookies https://support.mozilla.org/en-US/kb/ho ... efox-cache
3. Download the universal installer https://lastpass.com/download/cdn/lastpass_x64.exe
4. Restart your device > run the universal installer normally
5. Enable cookies https://lastpass.com/support.php?cmd=showfaq&id=11472
6. Install the binary component https://lastpass.com/support.php?cmd=showfaq&id=5576

Einfach zu handhaben,

je regrette qu'on ne nous explique pas pourquoi cette extension, pour laquelle je paie un abonnement, cesse de fonctionner. Et aussi qu'on ne nous propose pas une solution alternative.

I've been using LastPass for years and it is great, but the extension for Firefox does not work as well as it does for Chrome. There is no quick way to copy a password into clipboard, and some actions are broken and lead to a blank page. The LastPass team really needs to look at fixing this extension for Firefox.

Lastpass is ok. If you are missing some features like the Copy Password button, you need to install via the installer from their web site. There is a binary component that is not included when you install from here. See:

It's great in the fact that it stores my passwords securely and I don't need to remember them because it auto-fills them. However, I always need to fill in a security challenge which is a waste of 10 seconds everyday. The UI also isn't the best, but I can deal with it.
