discuss.kde.org cannot be accessed by konqueror. It gives this message “Unfortunately, [your browser is unsupported]. Please switch to a supported browser to view rich content, log in and reply.” KDE’s web browser does not support KDE’s discuss web site. It looks like a strange situation.
Justin and I also talked about this on the Fediverse concerning Falkon (btw. Kudos)
You could circumvent this message by adding an adblocking rule like: ||discuss-cdn.kde.org/brotli_asset/browser-detect-*.js
You could register, login, access and even work on your profile by this. However, you won’t be able to post anything (at least I couldn’t, the post button does nothing, all others work). So you’re mileage may vary but I’d wait for a QT6 QT Browser.
OK, so I managed to reply from Falkon, but only by hacking around in the developer tools (in addition to using an ad blocking rule for ||discuss-cdn.kde.org/brotli_asset/browser-detect-*.js). The trick is to open the console, click on the discourse-….js link in the backtrace (not the composer.js one, editing that has no effect), commenting out the lines 2858 and 2859, then right-click, Save as… on the tab title (which does not actually open a save dialog, but puts up a warning sign that the file was not saved to the file system, but seems to be enough for the changes to be applied to the running session at least). Ewww! But this is how I have posted this message.
It would be helpful if KDE patched their Discourse to actually work out of the box on KDE browsers. It should be enough to
remove || !CSS.supports || !CSS.supports("aspect-ratio: 1") (or even just || !CSS.supports("aspect-ratio: 1"), though the check for CSS.supports was added by upstream only to support that) from the browser detect script and
remove that document.querySelectorAll call from composer.js.
After a few attempts, I finally got the AdBlock rule to work (hint for others: it seems that reloading the page is not enough, I had to open a link from discuss.kde.org that I had never opened in another tab, and I finally got the correct look without the “unsupported browser” error message).
So I can browse the site correctly, but indeed, no way to post anything, or even to reply to a message: you can type your message, but clicking the “Reply” button does nothing.
Is there any “official” way of asking for the change you suggest to the site maintainers? This looks simple enough, and it’s indeed a bit of a shame to have KDE’s own browser(s) not working on one of their own websites…
