Here are some of the things you can try: 1)Update Firefox to the latest version: Outdated versions of Firefox may have bugs or compatibility issues that can cause tabs to crash. Updating to the latest version can help fix these issues. 2)Clear your Firefox cache: Over time, the cache can become cluttered with old data and cause problems with the browser. Clearing the cache can help resolve these issues. 3)Check for and disable any conflicting extensions: Extensions can sometimes cause conflicts with each other or with the browser itself, causing tabs to crash. Try disabling any extensions that you think may be causing the problem, or try using Firefox in Safe Mode (which disables all extensions) to see if an extension is the cause. 4)Reset Firefox: If none of the above steps help, you can try resetting Firefox to its default state. This will reset your settings and remove any extensions, themes, or other customizations you've made. I hope the above suggestions would be of help :)
