Does Firefox support Chrome extensions?

No, Firefox doesn’t directly support Chrome extensions.

It uses different underlying technologies, making it incompatible. Now, at this time Firefox Add-ons cover almost every extension alternative. Here are a few ways to get similar functionality:

• Firefox Add-ons: Firefox has a vast library of add-ons, many of which offer similar features to popular Chrome extensions. You can browse the official Firefox Add-ons store to find alternatives.

• WebExtensions Porting: Some Chrome extensions are built using WebExtensions, a common standard for browser extensions. These extensions can often be ported to work on Firefox with minimal adjustments. You can search for ported versions of some popular Chrome extensions.
