@VirtuallyCreative That is a old bug in Vivaldi. If you dock the dev tools windows, you can change the device.

@Pathduck Wow, that approach would never come to my mind and it indeed works! Thanks again for your help

@Gwen-Dragon as I've mentioned, this mod causes the same bug as the floating panels and tries to do the same. After changing the code from this: #main .inner { position: relative; } #panels-container { position: absolute; z-index: 1; top: 0; bottom: 0; background-color: var(--colorBg); } #panels-container.right { right: 0; } To this: #main .inner { position: relative; } #panels-container { position: absolute; z-index: 1; height: 100%; background-color: var(--colorBg); } #panels-container.right { right: 0; } #webview-container { margin-left: 34px; } Everything works as expected. I don't know if the floating panels provided by Vivaldi work the same way, but maybe this information can also be helpful.

@Chas4 Thanks for the report. I will add a report internally for Vivaldi. VB-60645 "UA Strings are getting outdated"

@JoeC00L Yes, the Bug was fixed in 2.9 RC1. Now you can use some parts of Developer Tools without any trouble.

Ok, thanks

@Gwen-Dragon I don't know… I tried to make it happen again, but couldn't. It looks like it's one of these bugs that always happen, but are never reproducible

@potmeklecbohdan I confirmed.

@nymsapet I checked my 2.6.1566.44 Stable on Win 10 x64 1903, no crash for me. Do you get a crashdump in %LocalAppData%\Vivaldi\User Data\Crashpad\reports\ ? How can i test this crash? Please give me some steps to reproduce.

Another +1 from here. For my use case - I'm developing a web app, and would like to show it to the "client"; however, when they load it they see a cached version rather than the full version. Because of this, I think there's a definitely use case for having right click functionality on the 'refresh' button for all users - left click performs a standard refresh, right click gives you different refresh options, e.g. hard refresh, refresh every N minutes, etc.

Ah it looks like it is working only in docked mode. (which somehow did not work in my case earlier). Good work around for now! I hope the undocked mode also gets fixed soon;

@DatLicht said in [bug] Vivaldi crashes on opening developer tools: After disabling all extensions and re-enabling them again, the crash disappeared. A broken extension which may have go a update? Fine that you could solve your issue.

@Eunoseer said in Drop-down menus for Developer Tools when in "Toggle device toolbar" not displaying next to menu button: VB-60265 You bug is a duplicate. FYI: VB-49323 "Device toolbar mode device switcher is broken with undocked dev tools"
