Me again.

I hae tried downgrading my firefox version and still the same issue with all of my addons. I tried installing again the delicious bookmarks add-on to see if that would work and it gave this error:

Firefox could not install the file at

https://addons.mozilla.org/en-gb/firefox/downloads/file/67442/delicious_bookmarks-2.1.072-fx.xpi?src=creatured&confirmed=1

because: Unexpected installation error Review the Error Console log for more details. -203

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry. See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions If you see disabled extensions that are not compatible on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button to do a compatibility check.
