@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 VB-60645 "UA Strings are getting outdated"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.

This would be an excellent feature to have, especially if it could be configured to be always on for specific domains or IPs, e.g. localhost/127.0.0.1

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"

@Niiicooo Hi! Regarding the shortcut closing the window again: This kind of thing is tricky to nail down. Right now, undocked dev tools behave the same way as they did in classic opera: I.e. the shortcut opens them, and if you press it again it closes them. However you are correct that chrome keeps them open always, and this is what firefox does as well. Perhaps the "classic opera" behaviour is outdated, and it definitely makes more sense to me to have it re-focus the window like chrome does. Perhaps you could write your opinion on this feature request: https://forum.vivaldi.net/topic/31676/hotkey-to-focus-developer-tools/ Regarding showing the title in undocked dev tools: I think this should definitely happen. You could make a new (separate) feature request for that, as I don't think one exists already.

И сам браузер чтобы запоминал размеры и положение после перезапуска, а то замучил скидывать на какие то свои значения.
