Problems installing or updating VimFx

[girst]

There are a few unresolved issues when installing legacy extensions. This ticket attempts to list them, as well as some workarounds.

Generally, before reporting bugs, open the Browser Console by pressing Ctrl-Shift-J and look for errors when trying to install or use VimFx. If you can, check if you can reproduce the problem in Nightly.

The add-on VimFx can not be installed from this location. // The add-on could not be downloaded because of a connection failure.

use one of the following workarounds:

• set extensions.install_origins.enabled to false in about:config (on Firefox >= 96)
• drag the VimFx.xpi link into the browser's URL bar
• right-click->Download the XPI, and install it from the Wheel icon->Install Addon from File on about:addons

The add-on downloaded from this site could not be installed because it appears to be corrupt.

• check that LegacyFox is correctly installed. See this troubleshooting guide.

VimFx could not be verified for use in Firefox and has been disabled.

This text appears on VimFx in about:addons. It is wrong and can be ignored; VimFx will work regardless. This message is shown due to a limitation of how LegacyFox hooks into Firefox. If it bothers you, set xpinstall.signatures.required to false in about:config.
