I had tried most of your solutions over the last 6 months still gettin same problem tab crashes

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/Unsubmitted 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!

Is this with all websites/pages, some, a few?

ONLY WITH SOME

Are you using Bitdefender?

We have recently seen multiple reports that Bitdefender is causing issues with tab crashes in Firefox 73. Bitdefender has pushed an update to address this issue. See comment 2.

Issue was apparently on us and was affecting users of Bitdefender AV free.
We pushed an update about 2 hours ago with the fix.
You should see a drop in crashes as update propagates across market.
