Any attempt to update existing or new extensions gives me this text in swedish: "kan inte installera filen på https://addons.mozilla.org/firefox/downloads/latest/3064/addon-3064-latest.xpi?src=search p.g.a.: Ogiltig filhash (möjligen en skadad filhämtning) -261" or similar to all my attempts. I can still install extensions through other webpages, but not within the extensions menu in firefox.

I use a Mac with 10.6.6. Please help me! Already tried to delete the .ini files....

Thx

If Firefox gave you the following error message: Firefox could not install the file at https://addons.mozilla.org/******.xpi because: Invalid file hash (possible download corruption) -261

This error message may be caused when Firefox is set dis-allow third party cookies. To accept the third party cookies: go to Tools -> Options -> Privacy -> tick 'Accept third party cookies'.

I get that error message even though I already have ticked the "Accept third party cookies".

Please help me! I´ve tried to solve this so many times and now I need your help cause I can´t figure it out.

Thx!
