at present, two browsers are installed on the PC side of the computer. The browser version and model are attached to the picture. They are the following two versions:


1Firefox Developer Edition
2Firefox Quantum

Firefox Developer Edition Firefox Developer Edition Firefox Firefox Developer Edition Firefox Quautum

result: an attempt has been made to uninstall and reinstall the browser and exit the Synchronize account, but you still can"t let both browsers run at the same time.

is there any other way to solve this problem? we need to use these two browsers in the front-end development. Thank you very much! Look forward to reply
