Hi, I am learning web development. I am into AJAX now. When I try to use `load('ajax/somedata.txt')` in a local HTML file, I get the error:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at file:///home/sourav/The%20Complete%20Web%20Development%20Course/JQuery/ajax/somedata.txt. (Reason: CORS request not http).

Same happens with other browsers. But Falkon browser is an exception. The other way to fix this is running an http server (like WEBrick).

Just because Firefox is my favourite browser, I want to load up the file correctly in Firefox. Is there a way to do that without running a local HTTP server?

Actually, the article mentions the preference you can use to roll back the patch, but to use that, you may need to know the steps to change a preference.

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

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

(3) Double-click the privacy.file_unique_origin preference to switch the value from true to false

To mitigate the vulnerability this patch addressed:

Save pages from untrusted sites in a completely separate folder, e.g., Downloads\Untrusted. That would make it difficult for an attacker to find any valuable content using local file links.
