1647619 - Intranetsite based on Sharepoint gives NS_ERROR_FILE_CORRUPTED

Status: RESOLVED DUPLICATE of bug 1341070

(Core :: Storage: localStorage & sessionStorage, defect, P2)

Description

[Wim]

We have an issue with Firefox 68 ESR when accessing an intranetsite which is based on Sharepoint. After using it for a while, it seems to corrupt localStorage and it starts to throw errors, like:

Exception... "File error: Corrupted" nsresult: "0x8052000b (NS_ERROR_FILE_CORRUPTED)" location: "JS frame :: https://spoprod-a.akamaihd.net/files/sp-client/chunk.sp-pages-social_nl-nl_4ce026042c18403fbf69.js :: liQQ/Q</t.prototype._checkFirstRun :: line 1" data: no]

I am still investigating, but clearing localStorage as mentioned on some sites isn't an option for our users. We have Firefox in an AppV. We're also testing with Firefox 77, but it seems to appear there too.
When accessing the site in a private window, there are no errors at all.

Dear Wim, thanks for the report! This is a known issue (see bug 1341070) which will be solved by our ongoing overhaul of local storage (called "local storage next generation", aka LSNG). Actually LSNG is already incorporated in FF for quite a while but has not yet been enabled for the entire release population. You can safely try to enable it for your users by setting the pref dom.storage.next_gen to true in about:config, which might solve the problem.
Thanks for supporting Firefox!
