constant, reoccurring tab crashes

Hi,

Sorry to hear that. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about what happens.

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!

I apologize. I don't remember seeing this response. The 5 most recent submitted reports are:

Thank you.

These do appear to be quite all over the place.

Could you run some hardware stress test, to eliminate something like memory corruption and the like?

I've used Google's AI for help, as I couldn't make sense of the techno-gibberish from the app sites. Did the HP diagnostics, and passed all (component, memory, keyboard, can't read my writing for the rest) Everything was going well, until I tried to shrink the bars, which are now perfect, but the font in the page is miniscule. Again. I don't want to affect the bars...just remembered the default zoom. Set to 100. Also refreshed Firefox. Is there anything else i should try? I'd like to close this ticket, but don't know if crashes will continue to occur. Can I renew it if necessary in a few days? Also, thank you all for your help. I appreciate it.

Within 2 miutes of sending above reply, had another crash.

Could you create a new separate profile and try using that one for a bit? Or maybe even better, download a separate build, like a https://nightly.mozilla.org/ that won't interfere with your existing setup, and try running that one?

I did not see anything suspicious in the crash logs, but try disabling any anti-virus or malware protections you might have on your system as well.

The Nightly Mozilla thing gives me an empty set (red circle w/diagonal line thru it). The profiles confuse the hell outa me. I only had one when I started FF years ago, then all of a sudden there are several. How'd that happen? This is really bugging me. I spend more time sending crash reports than actually doing what I need to do with the browser. What do I need to do to create a new profile? Can I take all of each current with me? How does that work? Sorry for being so dense, but I'm really lost. Thanks. And sorry for taking so long to respond, but the post got lost in my sent folder instead of current inbox.

I must have assumed you've been using browser profiles based on the original post "All the tabs, in both my profiles […]" — hence why recommending a fresh one implying you're familiar with that functionality and using whichever method you currently use.

There's actually two places, the older and the newer feature:

• Manage Firefox profiles
• Profile Manager - Create, remove or switch Firefox profiles

The point in trying out a new one is to eliminate anything in the old ones that can cause crashes, leaving all preferences behind at this point to see if it makes any difference.

The safer way to try the same without messing with the existing installation (which I'd prefer) would be running a Nightly or Developer edition on the side. No idea why you're unable to run that. Maybe the Dev installer: https://www.firefox.com/channel/desktop/developer/ would work better than the Nightly?
