I brought a new system with latest OS Big Sur, I'm using Firefox v49.1 (required version) for my official purpose. So I installed this version in my Mac and it works smoothly, suddenly it quits and showing crash alert. I reinstalled again and again, but it's not worked. I fed up with this issue. Please guide me to solve this. Previously I was using Mac with High Sierra OS. That time I haven't face this issue ever.

Firefox version 49 ... really? That version is over 4 years old (see the release calendar) and is no longer supported. In any case, the article Firefox keeps crashing at startup recommends a clean reinstall.

You can uninstall the current Firefox version before installing, since this will not remove your user data. (Open the Applications folder in Finder and then drag the Firefox application to the Trash.) Afterwards you should install the latest version of Firefox using these instructions: How to download and install Firefox on Mac.
