Is there a [plan to fix 4.0 so that all the previously useful add-ons and plugins will function? Delicious toolbar is disabled; Norton toolbar is disabled; several other add-ons that worked perfectly well in 3.6 do not now

more options

the upgrade caused several tools that I use every session to be disabled as they were incompatible with 4.0

this was not an enhancement to me; rather it has caused me more aggravation than anything the old version did.

Those add-ons for Firefox need to be fixed.


Here's a simple trick to make the Delicious bookmarks Firefox add-on work after upgrading to Firefox 4.0.

This assumes that you previously had the Delicious bookmarks add-on working in Firefox 3.6.x and you have just upgraded to Firefox 4.0 – which disables the add-on and states that it is incompatible with Firefox 4.0

  • Open Firefox
  • Goto “Help” in the Menu, then “Troubleshooting Information”
  • Click on the “Open Containing Folder” button (within the box “Application Basics” on top of the page)
  • Close Firefox
  • Goto into directory “extensions\{2fa4ed95-0317-4c6a-a74c-5f3e3912c1f9}”
  • Edit install.rdf and change the following from the first line to the second line
     em:maxVersion="4.0b3pre" />
     em:maxVersion="4.0.*" />
  • Restart Firefox

Norton says they will have an updated version of their Firefox extensions available in May.
