Great news – many thanks!

Loaded and running, many thanks for these changes and added features.

Great improvements!
I guess you are motivated to improve it more:

1. The BBC page still makes problems with fonts:

2. One thing I don’t like on NetSurf is that is opens only a tiny window. Can you make it configurable? RUN parameters would be fine.

I’ve seen the same effect on Firefox, Chrome and Edge when an SSL inspecting device (proxy or firewall) messed up the CSS

Use the windows ‘Template’ editor to resize the main window template.

Or simpler solution, use Display – Window – Set Default Position from the main menu!

Using this latest version of Netsurf right now. Thanks for all the work in producing it. I use Netsurf a lot.

Thanks for the continued development. It’s important for NetSurf to keep up with presentation features.
IMHO NetSurf is the best browser on any platform for seeking information. Its limited functionality is a real strength here as you get a calm browsing experience without the distraction of roll-overs, pop-ups, dropdowns, autoplaying videos and other stuff that gets in the way of reading the web page information.

NetSurf 3.11 is now available from the website.

Installed here and working nicely. Its fast even when run off sd card. We’re blessed to have an open source browser like netsurf, a big thank you to the developers for continuing to support risc os

Thanks @Colin Ferris and @Bryan Hogan
Both hints work but Bryan’s is probabaly the better choice. This should be added to the FAQ of NetSurf.

Will the update be available on Plingstore?

Not that I can’t update manually.

Maybe you can have a look at this website.
It looks quiet simple but NetSurf shows only blank page.
www.mupdf.com

If you access it with e.g. Firefox with javascript disabled it also gives a blank page.

Disabling CSS got a minimal display back.

If you access it with e.g. Firefox with javascript disabled it also gives a blank page.

If you select “Inspect” on the blank page, hit F5 and then select the initial www.mupdf.com in the “inspect” to open a new page, then that works, equally feeding the URL to Edge works.
An unusual fault, but the issue is on the server, not in anyone’s browser.

Netsurf doesn’t currently have the required dynamic page layout capabilities so javascript doesn’t have any effect on the page rendering. See here for details.

No login possible.

No login possible.

I don’t think NetSurf can be used with eBay anyway. AFAIR, eBay has a very dynamic UI which uses heavily JS, both these two things are not yet fully working in NetSurf.

I recall you’re using just emulation right? If so that’s it, otherwise you could try Iris or OWB on a Raspberry Pi. Iris I remember it worked when I tested it, OWB I still haven’t tried (just lack of time to run these tests)

HTH

Yes, I have used RPCEmu with Risc OS 5.28. On my Raspberry Pi 3b+ with Risc OS 5.28 I use Iris and ebay.de is working.

Netsurf 3.11 crashes, especially when a HotList is present or generated, when Territory 7 is activated and the corresponding module is loaded.
