My slow about:config is on a new N800 flashed to the new OS and with no restore.
However I did not try it on the newly flashed system but only after installing a whole load of stuff. So in my case it has nothing to do with restoring from a backup.
My about:config on my N810 has been slow since day 1 - no restoring from backups, one update (very first thing when taken out of box). There is absolutely no change in speed after 2nd update (to 50-2 from 44-19) and restore from backup.
It's strange that some of you are getting quick showing of your microb about:config files. I had searched this forum to see how to change font size in microb and that's where I heard of about:config and was warned in those posts that it was very slow and that I should grab a cup of tea/coffee while I'm waiting.
Changing the up/down buttons to Page Up/Down was not exactly "easy" for a Linux newbie like myself. More of an ordeal. It involved installing emelFM2, discovering the editing function in that mess, discovering that editing /usr/lib/microb-engine/chrome/toolkit/content/global/platformHTMLBindings.xml doesn't do anything until you change permissions on said file (not that there's any message indicating that), chdir to that looong file location, chmod to give group permissions write access to that file, edit the thing again while trying to see nearly invisible text...
Hi,
to get around the chmod stuff, I just used X Terminal, used "sudo gainroot", started emelfm2 as root, edited the file in question and closed it again.
Editing the prefs.js doesn't need root so I started emelfm2 from the launcher menu.
