NoPE Proxy Tab wont show

Bassem | Last updated: Apr 28, 2021 12:51AM UTC

Hello, I'm using Burp suite community Edition v1.7.36 and I have loaded successfully the extension manually through the BApp Store and I have used it for many hours. Now, the NoPE Proxy Tab disappeared and I tried the following steps to get it back: -Reinstall it through BApp Store extensions lists. -Load the NoPE Proxy jar file from the Extensions Tab and the extension loaded successfully without any error but the Tab wont appear. - Delete Burp suite and it's temp files then re try to load it but same issue. I dont know if this may happened when I have checked/unchecked Extension Loaded option in the Extensions Tab for the NoPE Proxy extension. *Installing another extension works fine and it's tab appears + I have tried also on Burp suite community Edition v2021.4.2 but doesn't work. Is the problem caused by some temp/config files that wont be deleted on uninstallation? and Can you please provide me a solution to reget the NoPE Proxy Tab again? Thanks in advance,

Hi Did you have any other extensions installed at the same time as NoPE Proxy?

Bassem | Last updated: Apr 28, 2021 11:50AM UTC

Hello, Yes, I have the Random IP Address Header extension and its Tab is showing properly.

Hi Could you try uninstalling all other extensions and then reloading NoPE Proxy? We've just tried loading it in on both v1.7.37 and the latest version of Burp, and it has loaded in fine. It does take a few seconds to load though. Could you also check that you have performance feedback enabled, and if you do, send us your Debug ID? You can find this by going to "User options > Misc > Performance feedback".

Hello, Thanks for the updates. I tried to remove all extensions and then re-add the NoPE Proxy extension as you suggested but the tab still doesn't appear. (Added though a .jar file from the Extensions Tab) >>We've just tried loading it in on both v1.7.37 and the latest version of Burp, and it has loaded in fine. It does take a few seconds to load though. Yes, it works I have already used the NoPE Proxy extension on this version until my burp suite crashed while using the extension Tab. After that, the extension disappeared and I wasn't able to reload it anymore. Please find below my Debug ID: jdo7k07j345vf97f12dk:6g0a Thanks,

Hi

Thank you for that information.

You are getting a lot of errors reported from your installation ID that are to do with NoPE Proxy.

Could you try deleting the NoPE Proxy folder that is located at "~/.NoPEProxy", then reinstalling the extension?

Do you have any further details on the actions you were performing before this issue was triggered? We would recommend raising the issue with the developer of the extension here

Hello, Deleting the ".NoPEProxy" folder as you suggested have solved the issue and the Tab will load properly. Thank you for your support and time.

Glad to hear it! If this happens again, we would highly recommend raising this with the extension author.

Hi; I am having the same issue on Burp Pro v2022.8.4 It was working fine until this morning, but first my PC restarted by itself few times and now NOPE Proxy wont work. I tried deleting & installing and deleting the said folder, yet no changes. Could you help me as well? It even causes burp to freeze fully. I also tried on another PC with same version, there the tab shows, but won't work properly. It would start, appear as if it is running but it won't run. Also I wont be able to stop it as well or might give "bad memorry error" under dashboard. DebugID: ty43x5gpylf2wwr48x6l:iojx

Hi Are you using Burp with an existing project file or a temporary project file? Does the error tab for the extension come up with any details, or does it stay blank? When your computer restarted, was Burp open, resulting in it closing unexpectedly?

Berk | Last updated: Sep 12, 2022 01:10PM UTC

Hi Hannah; Thank you for quick response. I tried both existing and temp project. Error tab gives no errors: - For the case the extension tab shows, no error it gives the network names ( intel processor) - For the case that the extension tab doesn't show, no error, blank. (mac M processor) Burp was open, but I am not sure if it was Burp caused the restart, I am assuming only. And currently, there are no restarts. But on the dashboard, I saw a "bad memory error" on the Burp Dashboard.

Hi all; It seems to be working with v.1.7.37 jar file for some reason.
