Greasy Fork

Weird problem with Greasemonkey 3.17 or problem with your last Update ?
Before i can use your script with it whitout problem.

I know you don't use it...

But it's possible that something in your script interfere with the greasemonkey menu (which appear when we click on its icon in the module bar)?

In this configuration, When i install your script, this menu show no userscripts installed.

But they are here and work.
And if i go the Top Menu bar > Tools > hover the greasemonkey menu:
I can see the script list.

I tested too on a other profile (before, i backup it!).
Before i install your script, that's ok (i can see the userscripts list) .
After install your script, no userscripts shows in the menu.

After restoring the previous backup, i disable Greasmonkey 3.17 and enable tampermonkey.
I can install your script with it, and it work.
And Greasemonkey continue to work too (when i re-enable it...)

Yes , that's fine, but i am curious to understand why this problem appear with greasemonkey 3.17

Last test:
On a Very Fresh profile (only Greasemonkey 3.17 installed).
I can install other userscripts without problem.
But, when i install your script , i can't see it:
No with the greasemonkey icon and in the greasemonkey menu too (where all previous userscripts are gone).

Last Note:
Geasemonkey 4 don't work well with Waterfox Classic:
I can't see its menu when i hover its icon, is see only its arrow.
The only way to see its menu it's to go to "about:addons", where its dropdown menu work.
And the userscripts installed are not listed in the "about:addons" .

Sorry for this long report and maybe not related to your script:
Maybe you can suggest where i can found an explication.

Firefox is a nightmare when we want use old addons, no?

I just tried running Firefox Portable 56 (the last working with GM 3.x) and GM 3.17:
the script doesn't work and there's no error in Console.

So, unfortunately I can't help you, as I don't have any idea to suggest.

I just updated in the script's Info page that only Tampermonkey and Violentmonkey are supported.
GreaseMonkey (any version) is not supported.

Thanks for your quick reply!
That's a strange bug....
