When I log into LastPass, and go to Show Matching Sites/Edit, a new tab opens with a gobbledygook address, and the page remains blank.

The web address which is shown is, for example, "moz-extension://a8a47d14-a519-4b4e-a53f-9f4eacb7fb09/tabDialog.html?dialog=site" (without quotes). I am using FF 59.0.2 (64-bit) in Windows 10, with LastPass 4.9.2. I presume that one or both has updated recently, as it all worked fine until a few days ago.

Thank you, PKshadow and Cor-el. Your responses are very much appreciated. The issue was actually resolved by clearing the LastPass cache. Many thanks again.

Hi, it is most likely your Kaspersky Protection or WOT please try below : SAFE MODE

In Firefox Safe mode these changes are effective:

  • all extensions are disabled (about:addons)
  • default theme is used (no persona)
  • userChrome.css and userContent.css are ignored (chrome folder)
  • default toolbar layout is used (file: localstore-safe.rdf)
  • Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
  • hardware acceleration is disabled (Options > Advanced > General)
  • plugins are not affected
  • preferences are not affected

TEST''''is issue still there ?

If it is your Kaspersky Protection please see their Community Forum.

Please let us know if this solved your issue or if need further assistance.
