#22451 assigned defect

about:cache is not useful anymore in ESR52-based Tor Browser (only wyciwyg-URIs if at all any)

Description

I wanted to investigate #21689 and started to look at about:cache output to check for isolation keys. But to my surprise there is only garbage in it (in e10s mode), meaning all URLs start with the wyciwyg scheme, or nothing at all (in non-e10s-mode).

After re-reading #9336 I suspect the cached elements are basically not showing up in e10s mode either but instead some weird wyciwyg incarnations.

Now, I tested manually that things are still cached and that cache isolation seems to be working which is a good thing. But we should investigate and fix this issue as it is highly confusing and might conceal bugs we would otherwise see.

Direct link about:cache?storage=memory&context=p, shows cached images which are not isolated by #22327.

Yes, the fix for #22327 has not landed yet.

Hm, I found an unkeyed item in it today. I wonder how useful that about:cache page still is and whether it is actually telling the truth about the isolation...

That what I meant in comment:1.
Also about:memory shows that isolated entries look like

│   │  ├───2,053,002 B (00.52%) ── memory-storage(O^privateBrowsingId=1&firstPartyDomain=torproject.org,p,/M)

Therefore, the ^ sign may be a problem for chrome://global/content/aboutCache.js parser.
