I have around 15 extensions installed in Firefox. They all worked well until I updated Firefox yesterday. Last Firefox version was 1.5 and I updated to version 2.0. After this some extensions are working and other are not. Can you tell me what should I do to make all extensions work?Thank you in advance.
This is a compatibility issue. Some extensions written for version prior to 2.0 will not work on Firefox 2.0 and later. You will have to try to update extensions to be compatible with Firefox version you are using. Be warned that some extensions do not have updated versions for 2.0 and you will have to find some alternative extension.
