Trello not supported on the latest Mozilla Firefox's version

[ArmoVorigo]

Hi there,

I had to reinstall my firefox browser today, and Trello is not supported on the latest version ?

I use Firefox 106.0.5 (64 bits), and the error message is :

"Votre navigatueur n'est pas optimisé.

Trello est compatible avec les dernières versions de Chrome, Firefox, Safari et Edge.

Merci d'effectuer la mise à jour pour utiliser Trello."

(Your browser is not supported. Please use the lastest version of... etc.)

I use Trello on my company computer and I'm not administrator of it, it's hard to me to install new browser without my IT service. How is it possible Trello isn't working on the latest version? 

I wasn't able to contact Atlassian support, redirecting allways to te online community.
Thanks for help.

Do you have a plugin installed?  Is the browser not accepting cookies?  That version of Firefox should work fine here is some additional troubleshooting steps https://support.atlassian.com/trello/docs/troubleshooting-browser-issues-with-trello/

Thank you! Didn't think to check plugins. I deactivated one by one to find the one causing trouble. Probably the Qwant privacy plugin. Seems working now!

I'll save your link for future.

Good to hear that fixed it.  Can you accept the answer so others can find the resolution.

I typically use Chrome but I do have firefox and just updated it and tested it out and it does seem to be working for me, which I know isn't helpful for you, but does rule it not in fact working on any firefox browser. Are you running any extensions or something that could be interfering with it?

Thank you! Exactly, one of the extension seems to be conflictual. It's working now!
