Install the following Add-on until Google releases a new version of their toolbar that is compatible with Firefox 5. Most Add-ons that worked with Firefox 4 should still work with Firefox 5, but the developers need to update a line in their Add-on's code to indicate with which versions of Firefox the Add-on is compatible. The following Add-on adds a "Compatibility" button in your Add-ons > Extensions that you may need to click after installing it and restarting Firefox.

Thanks! If you post this reply in "known issues" it will help the many people like myself that didn't find this forum until they posted the umpteenth version of the same question! That, and you could make sure Google Toolbar will work with new versions before releasing them. Interestingly, I don't use Chrome because it doesn't support Google Toolbars and doesn't provide an automated way to transfer your bookmarks -- at least it didn't last time I checked, and IMO it was such a bad oversight on Google's part that it's not been worth it to me to go back to check again.

You are welcome.

So that other users can find solutions to previously asked Firefox support questions, please take a couple of minutes to return to the forum, sign in and click "Solved" next to my FIRST answer. Thanks.

It is the responsibility of developers of Add-ons for Firefox, including Google and their toolbar(s), to be sure that their Add-ons are compatible with new Firefox releases. Firefox 5 has been extensively tested including 7 beta versions over a 4-week period in which Google could have verified that their toolbar works with Firefox 5 and prepare a new release. The release schedule is not secret and developers know where to find that schedule. They failed, once again, to use that testing time to keep the users of their products happy.

Thanks. That was really helpful.

Come one, Helper7677, most add-ons are perfectly compatible across versions, developers should NOT have to edit their code every few months because Firefox updates major versions like mad every few months for the sake of catching up with IE 9 and Chrome 12 version numbers.

This is NOT efficient, generates a lot of redundancy, and is also totally misleading, because Firefox is pushing devs to release a so-called new add-on which is actually strictly identical to the previous version, except for the maximum compatible version number.

Besides, even admitting developers' agenda unlikely happened to match Firefox', they would all specify the same "5.0" number just so their add-on is not disabled, and will investigate possible compatibility issues later on. If they don't specify "999.0" once for all because this process is a joke...
