Vimfx doesn't work in Firefox 102

[yuandi42]

Vimfx (both v0.24.6 and v0.24.7 with latest legacyfox) stopped working as soon as I updated to Firefox 102. And I failed to reinstall Vimfx as Firefox claimed that an unsigned add-on couldn't be installed.

I've preform debugging steps below:

• resource://legacy/ gives you a list of three .jsm files (and that they aren't empty)
• open about:config and type 'general.config'. post results
  
• open about:support and search for 'application binary'. go to this directory and verify that config.js, legacy.manifest, legacy/*.jsm and defaults/pref/config-prefs.js are present.
  
• hit f12 to open devtools, ...
  
• where did you install firefox/nightly from (arch repo, aur, mozilla,...)? can you reproduce it with the binaries from 'https://mozilla.org/nightly'?
  Installed from arch repo

% paru -Qs firefox
local/firefox 102.0-1
    Standalone web browser from mozilla.org
local/legacyfox 2.3-1
    Legacy bootstrapped extensions for Firefox 65 and beyond

I didn't try to install nigthy from mozilla.org yet. I'm wondering how to solve the problem and I find it difficult for me to browse Internet with this add-on. Thank you for your prompt reply.

Same issue here :(. Can't enable the plugin either.

thanks for providing that.

Installed from arch repo

there seems to be a pattern of problems when installing firefox-nightly from the aur, maybe this also applies to firefox-release from arch-proper.

``` % paru -Qs firefox local/firefox 102.0-1 Standalone web browser from mozilla.org local/legacyfox 2.3-1 Legacy bootstrapped extensions for Firefox 65 and beyond

fyi, there's a new legacyfox version (v3.0) that'll be required for 103 or later. please pull v3.0 from https://git.gir.st/LegacyFox.git

``` I didn't try to install nigthy from mozilla.org yet.

please try that. other arch users have had success with that. you don't have to install it, just extract the tarball anywhere and install legacyfox with make install DESTDIR=/the/path/to/firefox/ (where firefox/ is the directory, not the executable)

Thanks. Fixed the issue. My steps:

wget https://git.gir.st/LegacyFox.git/snapshot/0548b59e51d966622e8733c62690078b61713d48.zip
$> unzip 0548b59e51d966622e8733c62690078b61713d48.zip
$> cd LegacyFox-0548b59
$> sudo make install DESTDIR=/usr/lib/firefox/
tar xzf legacyfox.tar.gz -C "/usr/lib/firefox/"

Then download the latest VimFx release. Don't try to install it directly by clicking on the latest release, but download the xpi file, and open it in firefox. Now it should be installed. Ignore the warning 'VimFx could not be verified for use in Firefox an has been disabled.'.

Thanks! Updating legacyfox works for my problem too.
