Recently, my Firefox updated and now I can't run bookmarklets anymore right after starting the browser.
Say I have a bookmarklet like
javascript:alert(123)
Then it works fine on every page, even on about:blank.But not right after the browser started with what is called "blank page" in the settings.
This is a bit cumbersome, because I often use a bookmarklet as the first step of my browsing session. A bookmarklet, which goes like "If TekMol is not on page B and not on page C, then send him to page A". So I start with page A, then click the bookmarklet again, get to page B, click it again and get to page C.
But that workflow is broken now. Must be some regression in the latest version of Firefox.
