Tab crashes

There is no way of knowing.

Do you check the task manager to see if your system is getting a bit loadded.

Can you also find any Fx log of crashes

I don't think there is an issue the system being over loaded but i was at the time on an online chat portal with an insurance agent and our chat crashed 3 times . Another time that will guarantee crashes 100%, is going on music sites with sound clips, after 4-5 clips, crashes always occur. As a note, this does NOT happen with other browsers.

Please follow the steps below to provide us crash IDs to help us learn more about your crash.

The crash report is several pages of data. We need the report numbers to see the whole report.

1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted (and Unsubmitted, if any) Crash Reports will appear, similar to the one shown below.
2. Copy the 5 most recent Submitted Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

It doesn't look like Submitted, it should start with bp-

Looking that those crash reports, I would start with making sure your copy of Windows is fully up to date.

Are DAILY, multiple crashes due to not updating Windows?

Yes, vast majority of these crashes happen on Windows 8.1.
