Det fungerar inte, har avinstallerat engelska och ominstallerat svenska. Ändå får jag röda streck hela tiden. Denna recensionen är helt full av röda streck. (utöver eventuella stavfel) Folk har klagat i över fem år på detta, ändå är det inte någon som gör något åt det!? Helt otroligt!

Värdelös. Gör inget för stavning, dåliga översättningar.

Not working anymore (Jan. 2022)

Tillägget fungerar inte alls. Det finns inte med i språkvalsmenyn när man vill rätta till ord.

Doesn't work anymore. When I click "Inspect" from the debugging interface in the add-ons manager I get this page:

Error
Cannot connect to the debug target. See error details below:
Error: Protocol error (unknownError): Extension not found: langpack-sc-SE@firefox.mozilla.org

Doesn't work at all.
Update: Still doesn't work at all.
Update: Worked for a while, now it's magically disappeared. Effin great.

It's very bad that as soon as Firefox is updated with a new version, the swedish language pack is incompatible!

Version 60 is still in beta, would be nice to have a language pack in Swedish which supports the non-beta version the rest of us uses.

EDIT:
Older versions for FF 59 can be found here: https://addons.mozilla.org/en-US/firefox/addon/svenska-se-language-pack/versions/

For version 60...
Rest of us are at version 59

Ändrar inte till svenska!!!!

I have same problem. After installation I cannot see languagepack in menu.
IMPORTEN:
Many have same problem. Why do you wnat us to write opinion, if you do not write answer for solutions?

Won't show up under "Languages" when right-clicking in a form.
