LetyShops extension not installed
Not sure what you’re trying to tell us here, were you unable to install the extension?
I cant find addon letyshops in addon list.
Link https://addons.mozilla.org/ru/firefox/addon/addon-letyshops/ doesnt works.
Does this addon was removed from mozilla add-ons repository ? If so - why ?
Usually the reason an extension was removed isn’t published publicly by Mozilla for legal reasons. It is up to leftyshop to state that.
If you know the extension’s ID you may be able to find out from https://blocked.cdn.mozilla.net/.
Though as the error page states, it is also possible that leftyshop removed it (and first published an update that removed the extension from your Firefox).
Unfortunately, we need to make some adjustments to the addon. Because it is temporarily unavailable for download.
I hope that in the near future we will solve everything, and it will again be available.
When do you plan to post an extension update?
