Utilitzant els complements

Què és un complement?
Add-ons are small pieces of software that add new features or functionality to your installation of Firefox. Add-ons can augment Firefox with new features, foreign language dictionaries, or change its visual appearance. Through add-ons, you can customize Firefox to meet your needs and tastes.

Funcionarà els complements amb el meu navegador o amb la meva aplicació?
Add-ons listed in this gallery only work with Mozilla-based applications, such as Firefox, Firefox for Android, SeaMonkey, and Thunderbird. However, not all add-ons work with each of those applications or every version of those applications. Each add-on specifies which applications and versions it works with, such as Firefox 50.0 - 52.*. For Firefox add-ons, the install buttons will indicate whether the add-on is compatible or not.
Quins tipus de complements hi ha?
There are several kinds of add-ons that customize Firefox in different ways:
  • Extensions add new features to Firefox or modify existing functionality. There are extensions that allow you to block advertisements, download videos from websites, integrate more closely with social websites, and add features you see in other applications.
  • Complete Themes change the entire appearance of Firefox, usually including icons, colors, dialogs, and other visual styles.
  • Themes are lightweight themes that use background images to customize your Firefox toolbars.
  • Search Providers add additional choices to the search box dropdown. These providers allow you to quickly search any website.
  • Dictionaries & Language Packs add support for additional languages to Firefox.
Com s'instaŀlen, es gestionen i es suprimeixen els complements?
In most cases, add-ons can be installed by simply clicking the install button provided. Add-ons can be managed, disabled, or uninstalled from the Add-ons Manager in Firefox.

Els complements poden fer que el Firefox vagi més lent?
Most add-ons do not cause a perceivable performance decrease in Firefox, though installing an excessive number may have adverse effects. If you suspect an add-on is causing Firefox to be slow, try disabling it.
Firefox told me an add-on isn't compatible. Is there a way I can still use it?
If an add-on isn't compatible with your version of Firefox, it is usually either because your version of Firefox is outdated or the add-on author has not yet updated the add-on to be compatible with a newer version you are using. Mozilla does not recommend trying to circumvent these compatibility checks, as they can lead to browser instability or in some cases loss of data. For users who are testing out alpha or beta versions of Firefox, we offer the Add-on Compatibility Reporter to help add-on developers update their compatibility.
Què passa si tinc problemes amb el complement?
Add-ons are usually created by third-party developers from around the world, so the best way to get help with an add-on is to look for support links on the add-on's homepage or contact the developer. If you are having issues with Firefox that you suspect are related to add-ons you have installed, visit this support article for troubleshooting tips.
Com puc saber quin complement he d'escollir quan n'hi ha dos que semblen que faran el mateix?
There are often several add-ons that have similar features. To figure out which is right for you, read the entire description of the add-on and view its screenshots. If there are still several in the running, read through the add-on's ratings, user reviews, and statistics to see which is most liked by other users. Remember that you can also just try out both and see which you like better.
What if I can't find an add-on I'm looking for?
With thousands of add-ons available, there's something for everyone. But if you're looking for a particular add-on and can't find it, you might try searching on other sites or posting about it in our Add-ons forum.
What does it mean if an add-on is "experimental"?
Experimental add-ons have been marked by their developers as not suitable for a wide audience. They may have bugs or not work properly. Use caution when installing experimental add-ons and uninstall the add-on immediately if you notice problems. Learn more about our review process
Què vol dir que un complement "no ha estat revisat"?
If you receive a direct link to an add-on that says it hasn't yet been reviewed, it means it's currently awaiting review by Mozilla. Use caution when installing these add-ons, as they could harm your computer or violate your privacy. Learn more about our review process
How much do add-ons cost to purchase?
Add-ons hosted in our gallery are free unless clearly marked otherwise.
What does it mean when an add-on asks for contributions?
Alguns autors de complements demanen als seus usuaris si volen ajudar econòmicament i fer una petita contribució per al desenvolupament del complement. Aquesta contribució va directametn al desenvolupador a no ser que s'indiqui que ha d'anar a favor d'un tercer, com per exemple una organització sense ànim de lucre com la Fundació Mozilla.
Què són els complements Beta?

Els complements Beta són complements que encara no han estat revisats i que representen la última versió en què l'autor està treballant. Ja que cada autor tindrà una forma diferent de valorar l'estat de la qualitat, heu de tenir present que aquests complements són menys estables que una versió normal ben acabada.

Please note that when you install an add-on from the "Beta Version" section of an add-on's listing, you will continue to receive updates for that add-on as they become available. Like the initial version you installed, all beta releases are not reviewed by Mozilla and may harm your computer.

Molts complement d'aquest lloc web tenen llicències de codi obert, que fan que el codi font estigui disponible públicament per copiar i reutilitzar sota les condicions determinades per l'autor. Molts autors decideixen utilitzar llicències de codi obert famoses, com la GPS o la BSD, en comptes de fer-se'n una a mida.
