Bookmarks in subpanel doesn't play macros

[viking2]

I am using the iMacros extension, https://addons.mozilla.org/en-CA/firefox/addon/imacros-for-firefox/, which lets you play macros in the browser. The macros are saved as bookmarks. When I click on such a bookmark, the marco is executed "Played".

However, when I click on such bookmarks in the subpanel, the macro is not executed. Sometimes, after a long delay, I get a TST popup stating "Permission Error".

Update: Today when I look at the iMacros bookmarks in the subpanel, they are all grayed out. Nothing happens when I click on them.
When I check the bookmark properties in the subpanel, all the locations are: javascript:(function() {try{var e_m64 = \

However, when I look at the location in the regular bookmarks, they are different and look like this: javascript:(function() {try{var e_m64 = "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", n64 = "U0wwMi1QZXRlci0zOChwcGFuNDQ0NCk=";if(!/^(?:chrome|https?|file)/.test(location)){alert('iMacros: Open webpage to run a macro.');return;}var macro = {};macro.source = decodeURIComponent(atob(e_m64));macro.name = decodeURIComponent(atob(n64));var evt = document.createEvent("CustomEvent");evt.initCustomEvent("iMacrosRunMacro", true, true, macro);window.dispatchEvent(evt);}catch(e){alert('iMacros Bookmarklet error: '+e.toString());}}) ();
(I removed some of the letters in the long string above)

I tried to replace the bookmark location in one of the iMacros bookmarks shown in the subpanel with the location in the regular bookmarks, but it didn't help. Same issue.
