cannot add search engine

When I try to add a search engine from https://addons.mozilla.org/fr/firefox/search/?atype=4 the browser tell me I must use a Mozilla based web browser despite I'm using Firefox 31.

Re: cannot add search engine

Which particular search engine you are trying to add and getting error?

Re: cannot add search engine

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

- in safe mode : no problems to add a search engine - I do not know how to disable hardware configuration - the default theme is the one only theme activated

Re: cannot add search engine

Did you check your extensions because this is likely a problem with one of them?

The add-on responsible seems to be : Unity Desktop Integration 3.0.2, desactivating it for me resolves the issue.

Since I'm using Ubuntu, I wonder what the desactvation of this plugin will cause however.
