Hello,
When I try to install the add-on in firefox from the addons.mozilla.org , I get the following issue:

I am using the latest version of Firefox : 117.0.1

[asenvolev]

Can you tell me how to install any version of the extension in Firefox if the latest one is not currently working ?

Odd, it seems to be working for me. What version does it list as the version you're installing?

[Methuselah96]

A new version just became available on Firefox, can you try again?

[asenvolev]

Reinstalled Firefox before trying
It looks the version is changed but Mozilla still do not allow me to install it.

[Methuselah96]

Strange, I'm not sure what's going on here.

[asenvolev]

Not sure if the problem is only in my PC cause on my colleague PC with the same versions of firefox and the extension it is working fine.

This is how i solved this issue:

1. Someone have to send you extension@redux.devtools.xpi
2. Go to C:\Users{YOURUSER}\AppData\Roaming\Mozilla\Firefox\Profiles then find the 12j234huh2.default-release folder which has many folders and extensions.json file in it.
   3.After you find that 12j234huh2.default-release folder open it and create extensions folder and paste in there this extension@redux.devtools.xpi file
