Found the issue. In the meantime you can edit .config/keepassxc/keepassxc.ini and change Enabled to true under [Browser].

Thanks

Just like to add that this affects the Win64 portable installation on Win 7:

When I try to enable browser integration the app crashes when I apply or ok the app crashes

Expected Behavior
Browser integration is enabled

Current Behavior
App crashes and browser integration is not enabled, this error is shown:

Steps to Reproduce:

Click box to enable browser integration
Click apply or ok

Unfortunately the workaround of change browser enabled to true in keepass.ini does not work. the same error message appears.

[phoerious]

You need to set it to false, not true.

[hughwilliams94]

Sorry I misunderstood the workaround I thought this would allow the use of the browser integration not just enable the app to open again. I did not have the setting enabled initially but would like to be able to use it.

[phoerious]

You can use browser integration if you disable the use of a proxy (either in the settings or via SupportBrowserProxy=false). In that case, however, the browser will try to open a new KeePassXC instance.

[hughwilliams94]

I currently have UseCustomProxy set to false in keepass.ini but setting enabled to true still crashes KeepassXC

[phoerious]

Sorry, my bad. It's not the custom proxy option, but the option to use a proxy which you need to disable.

[hughwilliams94]

Hmmm, disabling that does help resolve the error but there now seems to be no communication between the extension and KeePassXC even if I point the custom proxy location at keepassxc-proxy.exe

[Syping]

I had enabled Browser Integration in the last version and my KeePassXC doesn't start at all after upgrade:
It says it have Memory Access Issue similar to the Screenshot above in English. After Downgrade to last version it works fine again. It might be a good idea to take down the Installer because the issue will affect a lot of people.

[hughwilliams94]

I've also downgraded in order to keep the browser integration

[phoerious]

@hughwilliams94 When you disable the proxy, your browser will start a new KeePassXC instance. That means that you need to quit any running instance and then click "Reload" in the browser.

We pulled the 2.3.2 release and will release a fixed 2.3.3 later today.

[hughwilliams94]

I have tried all variants on restarting and reloading both browser and KeePassXC to no avail, I will happily wait for an updated version.

[phoerious]

Setting SupportBrowserProxy=false should work around it. But downgrading for now is a solution, too.

[WulftheNordicRanger]

Updating to version 2.3.3 seems to have fixed it

[hughwilliams94]

2.3.3 does not solve the issue on Win 7 64. There is no error but there is also no connection between KeePassXC and Firefox.

[varjolintu]

@hughwilliams94 I will check it out.

[varjolintu]

@hughwilliams94 I installed 2.3.3 and uninstalled the old version as suggested. Everything worked. Then disabled all the browsers from the settings and disabled the whole browser integration. Restarted KeePassXC and enabled the browser support again (tried what the browser extension said before, and it was timeout, so no connection). Still worked.

If you do the same steps, does it help?

[hughwilliams94]

Yes these steps fixed it, I think I just tried too many different combinations. Win7 64 portable works with browser integration now. Thanks for your help and the speedy fix everybody!

I got the same error, but in a different action.

I have a Keepass db, and move groups one into others; the first, works; second, make KeePassXC crashes.

It's a crash, but the problem is a totally different one. Mint 18.1 is based on Ubuntu 16.04, which comes with Qt 5.5. Qt versions prior to 5.6 have a bug that causes an application to crash in the situation you described. Please upgrade your system to a newer version or use our AppImage instead. See #335.
