View Full Version : Firefox extensions and FF upgrade risks

What is a good method or policy for installing and uninstalling FF extensions, esp. when upgrading to a new major version of FF?

For example, can merely upgrading FF, while one has an extension, incompatible with the new major FF version, already installed, potentially damage the new major version of FF itself?

If so, how does one check out currently installed extensions in one's FF to see if there will be problems BEFORE upgrading?

I assume that in most cases, when there is incompatibility with extensions, that one just deletes/uninstalls the old extension and installed a new version of this extension, if available?

Perhaps somebody knows the URL of a FAQ on these issues ?

When an extension is no longer workable under a new version of firefox it is disabled and shown as such by firefox in the extension pull down box. No risks involved. No worries either. You may then either uninstall the extension or leave it in the hope it will be upgraded to work with the newer version of the browser.

Generally speaking, Firefox automatically reviews installed extensions when it performs an upgrade and disables all those incompatible with the new version. It offers you the option of checking for upgrades of the extensions.

I assume that it knows what's incompatible by checking the version number of the installed extension(s) and then consulting some kind of database somewhere on the Mozilla web site ?

David,

Don't have a URL, but you are O.K. with the default settings as Earle says.

Extensions will either install or not and if not, no harm done.

As for version upgrades, you can either leave it to the default in which case it automatically does its thing whenever they post an upgrade, or change the settings to manual, in which case you should read MozillaZine to see if the new release is a winner or a dog.

And you can recheck periodically to see if an extension has been updated for this version by using the feature under Tools | Extensions | Update.

Each extension is labeled by its author, in a standard format that Firefox understands, with the range of Firefox version numbers with which it is compatible.

Before a new version of Firefox is released it undergoes beta testing. Extension authors can verify that their extensions work with the beta, fixing whatever is necessary if it doesn't. Then they release a new version of the extension that includes the new Firefox version in its label, hopefully before the new version of Firefox is officially released. If nothing needed to be changed to make it work, there may be nothing new in the new extension except its version number and its compatibility label.

Before you upgrade Firefox, you should go into Tools | Extensions and click on the Find Updates button to make sure that you have the latest versions of your extensions from those authors who are keeping up with the changes to Firefox. But if you forget, the new version of Firefox will offer to look for upgrades to any extensions that need it.

David,

One caveat on FireFox finding new extensions. Mozilla Org runs its own site of extensions, but does not cross-check with similar sites. One site that often has upgrades that Moz does not have:
