Firefox for Android won't remember menu setting for "load desktop version" ("Last ned desktop-sider"n norwegian)
Have tried this on both release, beta and nightly versions.
Also have problem with AdBlock Plus and AdBlock Edge settings. Some settings are not saved, and there is no way to edit filter list or add an image/ad from right-click menu (but I guess that question is better asked in the AdBlock groups :-)

You can use the Phony extension to always spoof your user agent. https://addons.mozilla.org/en-US/android/addon/phony/
For AdBlock their forums at https://adblockplus.org/forum/ are best.
But why doesn't Firefox remember this setting? Most pads have similar resolution to desktop PCs. And then one would want desktop-pages all the time. A bit unnecessary to have to install a plug-in for that.
