Due to compatibility issues with Firefox 7 and future
Firefox browser releases, Mozilla labs is retiring the Lab Kit bundle of add-ons. 

In a notice issued on October 7, Mozilla has announced that Firefox will automatically remove the Lab Kit add-on within days "to restore Firefox's add-on update functionality and avoid potential stability and security problems." Meanwhile the advice to anyone using Lab Kit, is to uninstall it and restart Firefox to avoid having the Add-on Manager get stuck at "Updating add-ons."

Lab Kit consists of five add-ins from Mozilla Labs and while the individual add-ins, listed below with their links, will still be available, they will no longer be bundled together . The problem, it seems, does not lie in any of the specific add-ins, just having them in a single package.

• F1 0.7.5: For sharing links from within the browser
• Prospector – AwesomeBar HD 9: A satreamlined UI for find pages from your history.
• Prospector – Find Suggest 4: Get word suggestions from the page during search
• Prospector – Instant Preview 3: Preview pages as you select them
• Prospector – Speak Words 4: Type one letter in the location bar to go where you want.

Other Mozilla Labs add-ons for Firefox are available here: https://addons.mozilla.org/en-US/firefox/user/5133025/

Firefox's rapid update cycle might have been a good thing for users but for developers of add-ons it has been nothing but trouble. The changes introduced in each update often invalidated add-ons for no very good reason. It is perhaps only justice that Mozilla has some of the problems as well!
