I presume ''"Skype click and call"'' is official [http://portableapps.com/apps/internet/firefox-portable-esr Skype] software. If you need skype and this happens on every update an unoficial solution would be to install Firefox portable ESR as an additional browser and then use that for skype whilst using the fully updated Firefox Release for all other browsing. (Firefox Portable is based on Mozilla Firefox, the ESR version probably will remain compatible with skype and not have problems on updates ) * http://portableapps.com/apps/internet/firefox-portable-esr The official solution would be to use Firefox Releases and update Skype. Complaining to Skype as necessary when it is not compatible with the Firefox Releases. Skype will be aware of the Release dates and will be able to test and modify their software as necessary whilst using public pre release versions of Firefox. <br />Presumably Skype is controlled by MS and they would prefer you to always use IE and not use Firefox at all.
