Styles within pages are cached and don't reload. How not to cache styles in local pages?

Posted

When developing an html or svg file I repeat editing content and style information and reload the file in Firefox. When editing styles I can't save them notifying cache. When editing content in external editor and reloading file all style changes are lost. However when editing styles in external editor, I can't force to reload them without deleting cache in general and when continuing to edit styles in Firefox all previously lost changes are lost on locally stored file as well. So how can I prevent Firefox from caching style information contained in local html or svg files?

Hi Vollbracht, as far as I can tell, Firefox's cache settings don't distinguish different types of files. You could temporarily disable the disk cache and see whether that helps:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box above the list, type or paste cache and pause while the list is filtered

(3) Double-click the browser.cache.disk.enable preference to switch the value from true to false

Does that make it easier? More difficult?

Question owner

This is a good work around - at least when in a longer development session. Thank you! But the described behavior of Firefox should merely be regarded as a bug.

A solution would be, never to cache anything coming with local files. This should be default behavior any how. A solution would be to reload every style for every reloaded page. This should be default behavior as well as even complex css are a couple of bits only. An other solution would be never to cache different file content separately.

I don't know whether all of these solutions are realistic as styles are to be merged cascading. What can I do to follow up any of them?

Hmm, did that help on yours?

When I search the Disk cache page of about:cache (very slow loading 15000+ entries), there are extremely few file:// entries in there (only one after loading a few files). So I'm not sure what's going on.

(I habitually reload pages bypassing the cache -- Ctrl+Shift+r -- so I haven't noticed sticky style sheets from local files.)
