Hello jinz0,

could you post a link for this add-on? I cant find it. I think the problem is of the producer and not of Firefox. The add-on seems to be outdated and not updated of the producer. To get more information contact the owner of the add-on.

Do not hesitate to contact us further.

Is this about changing the Windows keyboard layout via the Language bar or about changing the spelling dictionary in Firefox?

I have exactly the same issue , on both my home computer and work laptop. Every fcking time, I have to right click, languages and then choose which one I want to use and this TWICE to switch it. First time it will just keep the original one. This is going on like this for at least 3-4 updates back. Both computers are running win 7 (one 32bit, other 64) and both have exactly the same issue. Currently running ff27.

Oh, to make it clear, it's in firefox, it has nothing to do with windows, we are talking about spellchecker, not windows keyboard layout.

Did you check for isues caused by installed extensions?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.
