Chicago Bears fans clearly want head coach John Fox gone.

Throughout social media many fans have taken to changing their profile pictures or avatars to the logo of Firefox, a free web browser. On Sunday afternoon at Lincoln Financial Field in Philadelphia, one fan brought a large Firefox logo sign to the stadium that was caught on TV.

On Monday the chief marketing officer of Mozilla, who makes Firefox, sent 670 The Score radio station in Chicago a statement about the usage of their logo by Bears fans.

“We empathize with Bears fans who are frustrated with their team,” Mozilla chief marketing officer Jascha Kaykas-Wolff told 670 The Score in a statement, via CBS Chicago. “Being unsatisfied with the internal workings of something you care about? We’ve been there. To release Firefox Quantum, our fastest browser ever, we had to bear down and replace many out-of-date and under-performing components. While it was at times difficult, we managed to soldier on, put more weight on our big shoulders, and as a result shipped an incredible product that sparked a huge increase in interest and downloads.

“We’re not here to start any trouble, but unfortunately, the logo used in the stands in Philadelphia was out of date. If any Firefox fans are planning on carrying a Firefox Logo to an upcoming sporting event and sitting in a highly visible location in the stadium, please send us a note on Twitter and we’ll do our best to get you on-brand.”

It appears that the only issue Mozilla had with the usage of the logo is that it is deemed to be out of date. Kaykas-Wolff also states that if anyone wants to send the company a note on Twitter they'll help get them an updated logo to bring to Soldier Field.

Chicago hosts the San Francisco 49ers this Sunday afternoon at Soldier Field and it would not be surprising to see more of these logos at kickoff in Week 13:
