Chrome extensions not working in private window mode


Recommended Posts

Hi guys,

I found a new problem when using Brave/Chrome browser with specific extensions.In some cases they aren't working in private mode and only in normal mode.I found some HLS player extension which allow to play HLS playlist urls in extension player by paste the url in browser.I found 2 diffrent HLS extension I tried for Chrome & Firefox.

Native MPEG-Dash + HLS Playback

Play HLS M3u8

So in both cases the extensions for Chrome are not working in private/incognito window and it get blocked by Chrome/Brave and I get this Error window to see when trying to enter a HLS playlist URL.


The question I have is why?On internet I found some infos about FileSystem API to detect Incognito mode when its disabled.Also a old method to look into "chrome://flags" list to searching for "Filesystem API in Incognito" and to enable it.In latest versions nothing is to find anymore about filesystem to enable/disable it etc.So my question is whether its working to get extensions like that also working in private mode?Firefox does work to use the same AddOn in normal & private mode but Chrome dosen't allow it in default state.In my case I just don't wanna switch from private mode to normal mode each time if I wanna use a extension like this and open a new second window extra you know.Would be better to open a new normal TAB instead (not sure whether its working to mix normal / private tabs in one window etc).So what can I do to make it work or find a de-tour / workaround to use this or other extensions (which are not allowed to use in private mode) in same single window?Maybe you know any solutions for that.Thank you.

Hi again,

whoknows did post this on the news channel....


Browser incognito mode disables FileSystem API, thats signalize is in incognito mode

....a script what can detect private mode..


...is now possible to make the extensions above ALSO working in private mode or not?

In case of "NOT POSSIBLE" then I have another question about Chrome / Brave.Why has Chrome no menu to customize the look like Firefox?In Firefox I have buttons for almost all menu points like Settings/AddOns/Tools etc I can set directly on the bar next to URL bar etc you know.This is very comfortable just using the mouse/click instead of menu or shortcuts.Has Chrome anywhere such icons I can set like in FF?

just have another small question about Chrome/Brave extension settings.So why is there not button the user can enable/disable the auto-update?In Firefox I have that choice for each single AddOn so why not having the same choice in Chrome/Brave too?Just working when unpacking a CRX extension file and loading it manually but thats not very handy.Is there any reason why they didn't added that in C/B browsers?

Hi again,

so I have another question about Chrome / Brave browser and using bookmarks.

So I have a bunch of bookmarks and many of them having just a blank icon instead of the used website icon.I found out that it seems to happen only when I add any bookmark in running private mode (mostly) and they are added without icon (blank icon).When I do the same in normal mode then the bookmark gets the website icon.Also when clicking any of my bookmark which has a blank icon in NOT private mode to visit that site then its getting the website icon right after.Why?What wrong with the private mode and Chrome not adding the website icon?Is there any option in the flags I have to enable etc?Thats pretty bugging becasuse I'am using private-mode as default and don't wanna visit the sites in not private mode JUST to get the website icon in my bookmark you know.How to fix that?

As I said, I have many bookmarks and I don't wanna visit any bookmark again in NotPrivateMode and get all icons.Is there any way to make a refresh to get all icons at once I have selected or anything like that?

Hi again guys,

does noboby has any idea how to get all bookmark icons back without to visit any site manually again in NOT private mode?So this behavior is really super bad.Why does Chrome/Brave does NOT read / add the icon of any webpage (who using icons) when I add any URL from private mode into my bookmarks!=?Just working in NOT private mode.So now I have that salad and its pretty bugging me just seeing so much blank bookmark icons.Is there no method to refresh all URLs at once or choosing some selected URL to refresh etc?I tried to find any extension but only found some called "Bookmarks Checker"...


...but it does not refresh the icons. :( Has anyone any else to offer?


EDIT: So I mean the private / incognito mode makes this trouble not to save/show icons when I add any URLs to bookmark.In normal mode it works and bookmark icons getting added / shown and also reloaded from bookmarks which was blank when using private mode.So at the end I'am always using / starting Brave in private mode via shortcut flag (--incognito) and browse in that way and adding URLs to my bookmarks etc but this mode makes trouble with the icons.Just try it out.

PS: Check the reason for edit... ;)

Added more clear info about the problem I have and do not find any solution to fix that problem I have and to use Brave browser go on in private mode and getting all icons added in my boomark list when I do add any desired URL I want during a browing OP!
