It used to show how big and extension was when you would look at that extension, like how many MB it is. Now that is gone and it is almost impossible to find out how much space the add on is taking. Most of these add ons don't have the information even on their websites. What gives? Can we bring this back please? These things are important to know!

Hi. Sometime over the last day or so I started having a problem with my 1Password Password Manager, an extension to Firefox that imports my ID and password to websites that require them. I am running Mac OS 15.4.1 and Firefox 138.0.3. Up to now it was enough to click on the 1Password icon on the right of the first "email" box. But now I get a popup saying "Press the 1 Password icon in your browser's toolbar to unlock". But I cannot find that icon in my Firefox browser. I assume it is a Firefox problem because I do not have the same problem when using Safari and 1Password. Help appreciated, ChrisD

Hi 🙂

Many extensions don't work on support.mozilla.org.

For ex, Clippings and Unicodify – Text transformer are very useful to write text. It's annoying not to be able to use them to write in https://support.mozilla.org/en-US/questions/new/thunderbird/form.


Seeing https://old.reddit.com/r/firefox/comments/tyytcy/how_to_get_rid_of_this_extension_restriction/i3vke2p/,


1) Why is support.mozilla.org privileged and can pull out information about visitor's system, while connect.mozilla.org cannot?


2) I see that:

  • Copy Link Text works,
  • Unicodify – Text transformer is able to read selected text but not to write in forms,
  • Clippings is not able to read selected text.

Is there a doc which explains what are the limits of what's allowed for extensions in "internal restricted sites"?
