internet does not work on laptop but works on other devices

I am having an issue that has been an on and off problem for the past month. I currently am using a browser called torch which is a chrome style browser. But my main browser is firefox. Whenever firefox is open I cannot browse the web and when I try web pages do not load on any browser that I try to use, although I am able to use both ipads that are in the house and any applications/programs works fine with the internet. But ones I close firefox all other web browsers on my laptop work fine. What could potentially cause this and what other details could I include that would be more helpful to you guys thanks in advance I have already attempted to restart my modem several times.

thanks guys ill have to try this when my computer shows signs of this issue again

This may be a conflict between browsers, but first: have you updated Firefox recently? Or do you have it set to update automatically?

This might help, it's from FF Help pages:
Fix slowness, crashing, error messages and other problems | Firefox Help

Scroll down to "Fix problems connecting to Websites after updating Firefox."

Using the FF Help can give you great assistance. (Menu Bar, top left in FF, click "Help".)

I have it set up automatically but i recently reinstalled firefox so I believe I have the most updated version
