Description

It would be nice to be able to reload certain assets without reloading the whole page. I'm thinking anything that can safely be reloaded such as images and CSS (JavaScript will have many implications).

The reason for this that often when using uMatrix I simply allow CSS/Images for one or more hosts because otherwise the page loads incorrectly. Quite often this is enough to get the page running, however, it requires a full page reload once the domains have been whitelisted (temporary or otherwise).

It would be nice if individual reload buttons are added for what some of these resources, this includes frames, images, CSS and media. All of these can potentially be reloaded without reloading the whole page and without breaking anything.

All of these can potentially be reloaded without reloading the whole page and without breaking anything.

Images/media/CSS/script are the resources of the document, only document can call them and users can only call the document, you can't call these resources directly.

Frames on the other hand can be called directly without reloading the entire page.

So is uMatrix unable to for example force load an image after it has blocked already? If that is the case in my opinion there's no point in adding such a feature for just frames especially considering how infrequent frames are used in comparison with other resources.

Browser itself can't reload an individiual image/css/media/script on demand. Right click on any image and look for "Reload image" option. You won't find it. There's no API in browser itself. Only possible with iframes.

Edit: "Reload image" does appear but only if you block images/media by size via uBO.

uBO has this feature, you can click to force the reload of images/videos that were blocked due to their size. For CSS I would need to experiment to find out if I can force a reload of <link rel="stylesheet" ...> elements (by possibly toggle the href attribute),

you mean No large media elements option ?

Just had a look, and I'm not sure of having it automatic like that. Often I accidentally click the wrong domains to white list, and subsequently disable it again before refreshing. Maybe it's me just being clumsy, but I just a lot of users will be in a similar boat. If it is just me, then maybe having it automatic like that is better (I'll get used to it).
