firefox settings - unable to modify preferences and change config
after the update from beta5 to beta6 had issues, I re-flashed the SD with brad new beta6. now to recreate my settings...
changed the display scaling to 100% to be able to install add-ons to firefox. successful. also, display is reset to 200% after reboot, like others have pointed out.
proceeded to adjust preferences and noticed that after selecting duckduckgo as default, the "additional search engines displayed" was able to remove amazon but unable to remove google or bing. did not try others.
changing of history settings said it requires a reboot to change. seems reasonable but the way it opened different size windows on consecutive tries seemed a bit strange. no option to delay reboot until changes complete.
proceeded to about:config, unable to toggle any settings.
all of the above was possible without issue in beta5. like someone else pointed out, I also would prefer the firefox-ESR version but understand that is not likely happening. :-)
