After the latest Firefox update, when I try to use gmail it keeps crashing.

I can quickly check from the crash IDs if you'll find some recent ones:

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.)

Mimi, there's an update available now — if you can check for it and apply by restarting, to see if that improves for you?

Here's what you asked for. I also get a screen that says "Oops--something went wrong. Recent changes have not been saved."

Thanks, these are consistent, and are out–of–memory crashes. There's a lot of reasons for these, I'll see if there's anything either recent, or Google–related.

If you restart into Troubleshoot Mode: Use Troubleshoot Mode in Firefox is there any change for you?

Ah, I see it now: it's Malwarebytes crashing these processes on out–of–memory on their side. You can either try turning that off (or checking for updates on their side if they have a fix), or looking into disabling any "safe web" or "https browsing" features in their settings, to see if it improves the content stability.

I still have the issue. Contacted Malwarebytes and they shrugged it off and said they're working on it. I'm not at all computer literate sa I'm not sure what you're suggesting I do. Should I just delete the app and either not restore it or find another safeguard software? I don't want to mess up Firefox. Thank you for your help

This might be out of scope here and at least I personally don't have the experience with their software so you might need to wait for somebody else to chime in, but this might be the functionality of theirs you'd want to try disabling:

https://help.malwarebytes.com/hc/en-us/articles/36231156084891-Windows-Filtering-Protection-conflict-with-other-antivirus-software

(steps to settings at the end of the help article on their site)

I'm not sure if this is the exact product you use, and also if just disabling these web protections will cease its libraries injecting into the browser, and then failing — or going into circles exhausting the resources. It eventually might need uninstalling if the crashes do not stop.

I was originally hoping that you'd just be able to make sure your Malwarebytes software is fully up–to–date, and with all available patches and definition updates etc. — but this sounds like they have a bug they need to fix yet and are running out of resources in your case:(

Try disabling the feature from their help article linked above first, that would be the best fix for now.

Thanks, I'll try. Software is up-to-date. Can't believe I'm the only one with this problem, though!
