I am crashing regularly. Have been for a couple months. Multiple computers as well. I have re-installed several times, and I'm still crashing. Firefox is my preferred browser, but I'm ready to drop it. Any suggestions on how to stop if from crashing?

We're sorry to hear that Firefox is crashing. In order to assist you better, 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.

these are the only 3 listed, and they aren't even recent. But I crashed today, which isn't shown here. It could be the continuation of a problem listed here.

Hi

Thank you so much for those crash reports.

As a first step, I would recommend making sure you have run all Windows updates.

Further to that, it looks like you may be using an older version of Firefox. I suggest checking to make sure that you are on the latest version and again running any updates as needed.

According to the "about Mozilla Firefox" tab, I am running version 152.0.5, and is up to date.

My windows program is set to update automatically.

And I have done a new install at least twice in the last maybe 3 months.

The crash reports submitted are however from last year (=from an old version, for issues long resolved). There's nothing reported from your current release version. If you face the same issue again, please follow the above steps again and share the most recent crash IDs here as well, this time they might be more relevant. Thanks!

That's what came up when I did the about:crashes report. But I'm crashing almost daily, and on 2 different computers. Both computers are Windows 11, and less than a year old. Don't know why more crash data isn't coming up, since it's happening so often.

But I'm using Chrome more than ever before, which I hate, but at least I'm not having to shut down and then re-login to everything.

Alright I found one more recent one, from 2026-05-20 — and that one says "Last Crash: 16 weeks, 4 days and 23 hours before submission" so for some reason your Firefox doesn't think it's crashing. 🤷

Anyway I see it's crashing in random spots, and its actually probably crashed by ESET (it's on the top of the stack).

Which now makes sense, because ESET is known to also block the crash reporter so it can't submit the reports:(

Is there a pattern in what you're doing that's triggering the crash from their side? (Like… dragging tabs between windows, dragging windows between displays, playing videos fullscreen or picture-in-picture, switching between graphic cards etc.)

Can you also make sure you're fully updated on both Firefox and ESET side of things?

Firefox and ESET are both up to date. Windows and MS Office up to date as well.

No pattern. It usually happens when I have 2-4 windows open, and I'm opening an additional window. I don't do fancy stuff like switching graphics cards, picture in picture, etc. Pretty basic stuff. Windows, Excel, Firefox.

I have Chrome on both of my computers as well. When Firefox crashes, Chrome is my back up.

This is the only crash report on my other computer:

Interesting that ESET blocks the crash report. But can it cause the crash? That would be interesting, because I have 7-8 computers in the office all using ESET. But only the two in my office are crashing.

In investigating window detach crashes eventually related to ESET Endpoint Security in bugzilla.mozilla.org/2023251 it was tracked to their eOppBrowser.dll (1.0.165.0–1.0.169.0) and the timeline also records the blocking of the crash reporter process and steps to exclude that from their blocks. That would maybe provide more reports from your devices, as currently there's most from 12/2025, one from 5/2026, one from 6/2026; none from the current release train.

Basically disabling ESET's "Safe Banking & Browsing" feature should stop them interfering with the tabs. Maybe that would prevent the crashes on your affected systems?
