If you’re downloading a large file in Firefox, it can slow down your browsing and streaming elsewhere. Learn how to limit download speed in Firefox here.

When you download large files, most of the time you want them to download as fast as possible. After all, the sooner they are downloaded, the sooner you can start using them. However, sometimes a large file downloaded at high speed can leave you with little bandwidth for other activities.

In cases like this, you may want to slow down the download so that you can use more bandwidth for other purposes. If you are a Firefox user, learn how to limit download speed in Firefox below.

Why would you want to limit download speed in Firefox?

Limiting the download speed may sound a bit counterintuitive. If you’re downloading a large file, you probably want it to download as quickly as possible. Limiting your download speed would mean that it will take longer to download the file.

However, there are situations where it may be desirable to limit the download speed in Firefox. For example, if you are downloading a large file at high speed, it may be consuming a lot of your bandwidth. If you’re trying to do something else that requires a lot of bandwidth, like streaming a TV show or movie, your content may start to buffer or play at lower quality.

By limiting your download speed, you can free up more bandwidth for other things like streaming.

Is it possible to limit download speed in Firefox settings?

Unfortunately, there is no native setting within Firefox that allows you to limit the download speed. In browsers like Chrome, it is possible to create a custom profile where you can set download and upload speed limits. In Firefox, this is currently not possible.

All is not lost, however. If you’re a fan of Firefox, you can still limit download speeds without having to switch to another browser. You can do this using a download manager or network traffic management application.
