Hi lukijosai
I was unable to replicate the issue. What Version of firefox developer edition are you using? And what OS do you have installed?

I tested with Windows10 64bit, MacOS 10.15 and also with Ubuntu 20 64.bit. Using firefox developer edition 87.0b9. When i go to wikipedia and click on the lock icon i see no problems.

Could you answer the following questions in order to further investigate this issue.

Does this issue happen with a new profile? Here is a link on how to create a new profile: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

Are you using any addons if so please list them?

thanks.

Thanks for the reply lukijosai

I tried again on Windows10 64bit, this time with FX developer edition v87.0b9, Build ID : 20210311161514
User Agent : Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:87.0) Gecko/20100101 Firefox/87.0

But this time i tried with the addons that you listed. ( Only one i was not able to find in addons.mozilla.org "IObit Surfing protection", how did you install it as an addon? I went to their website and it downloads an .exe file.

Please try the below in order to see if the issue still occurs:

1. Please try running firefox in safe mode. Here is a link that can help you do that:
   https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

2. If the issue still persists, please test it using a brand new profile, you can find the steps to do that below:

3. Does this issue occur in the latest nightly version of firefox? Here is a link from where you can download it: https://www.mozilla.org/en-US/firefox/channel/desktop/

please let me know

thanks

Interesting, safe mode removed the issue, but after restarting into normal mode it was back. I then manually disabled all extension, but the issue persisted. The IObit plugin was installed as a part of Advanced System Care.

What about creating a new profile? Please try creating a new profile https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles?redirectlocale=en-US&redirectslug=Managing-profiles#w_starting-the-profile-manager

then add each extension 1 by 1 and see if the error starts to appear.

thanks.

This bug is commonly caused by using bad userChrome.css stylesheets.

Can you elaborate on that? And maybe show a way to fix this in a nicer way than essentially reinstalling firefox?

After creating new profile and syncing with my firefox account, the bug did not appear. I think Tom Schuster may be onto something.

You can just go to about:config and set toolkit.legacyUserProfileCustomizations.stylesheets to false.

That did it, though I had a dark right click menu done using that option, now it is back to white :(

You will have to talk to whoever you got that stylesheet from. I am going to close this bug now.

Just out of curiosity, is there any other way to get darkmode to apply to right click menu? Maybe something official?
