How is it possible to download a firefox extension as .xpi-file from the official site https://addons.mozilla.org/ if not using firefox as a browser?

https://addons.mozilla.org/ in this case just shows "Only with Firefox—Get Firefox Now" instead of the install/ download button -- and when I click there, I am prompted to download firefox. But I want to get the extension (e.g. to install it manually on another computer, or in another browser like Pale Moon).

You can download an extension from Firefox:

  1. Go to the extension page, for example https://addons.mozilla.org/en-US/firefox/addon/ghostery/?src=homepage-collection-featured.
  2. Do a right-click on Add to Firefox button and select Copy Link Location.
  3. Paste the link to the address bar, then insert "/type:attachment" after file number: "https://addons.mozilla.org/firefox/downloads/file/3390826/ghostery_privacy_ad_blocker-8.4.2-an+fx.xpi?src=homepage-collection-featured" -> "https://addons.mozilla.org/firefox/downloads/file/3390826/type:attachment/ghostery_privacy_ad_blocker-8.4.2-an+fx.xpi?src=homepage-collection-featured".
  4. Open the link.

... or from any other browser:

  1. Open source code of an extension page (select the appropriate item from right-click menu of the page).
  2. Search for "platformFiles": string.
  3. Copy the file id that follows it (3390826 in example above).
  4. In the address bar type https://addons.mozilla.org/firefox/downloads/file/, then add the file id you got on step 3 and press Enter.

    The 3rd step is not necessary if the extension link is opened in Firefox. Also the ?src=homepage-collection-featured part can be removed from the first link. – Biswapriyo Nov 2 '19 at 19:52
  • The 3rd step is necessary if you want to download the extension instead of install it. – GCRaistlin Nov 2 '19 at 23:04
  • @GCRaistlin: But the question is how to download it without firefox. I have a reason to not use firefox itself. – Golar Ramblar Nov 3 '19 at 19:32
