Bookmarks from HTC Internet browser

Hiya all, I have an M8 and want to export my stock browser bookmarks to my HTC10. No idea where they are on the phone,lame I know but I have installed the HTC Internet app on the 10, but don't know how to get all my bookmarks off the other phone :crying: Any ideas as to how I can do this? Thanks in advance!

MyBackup Pro doesn't do it.

Problem exporting Firefox bookmarks on desktop to Firefox on mobile device

Hi, I'd like to use my Firefox bookmarks from my desktop on my Nexus 7. I can export them to a bookmarks.html file and adb push that file into the /sdcard/Download folder on my Nexus 7. But there Firefox can't read this file, it just shows me a blank page. No error message.:mad:
My Rom is a Cyanogenmod 13 snapshot from 2016-04-18 and the Nexus 7 is the "deb" version with LTE. And it is rooted.
Do I have to modify the file permissions, and how canI do that? The CM filemanager shows no option to do that, and the "chmod" command won't work.
And I wand avoid creating another online account (Firefox Sync) only for doing that.

Greetings,
Heinz
