After a little more study, here's a couple of things that might be worth knowing (at least about Firefox 11.x).
If you have edited about:config
, the value you enter there for general.useragent.override
is saved in .mozilla/firefox/your_unique_dir/prefs.js
user_pref("general.useragent.override", "Mozilla/5.0 (X11; Linux x86_64; rv:11.0) Gecko/20100101 Firefox/11.0 Slackware Linux");
That is, you can edit in about:config
or you can directly enter the above in prefs.js
using a text editor (which is what I prefer to do for what that's worth). You must exit Firefox (or Seamonkey!) before
with a text editor (any changes you make will be lost when Firefox closes if you don't exit it first).
If you want to know the actual, current, user agent, you can exit Firefox, delete the general.useraget.override
line from prefs.js
, restart Firefox and either choose Troubleshooting Information
in the Help
menu or go to http://whatsmyuseragen.com
and either will show you the default user agent (which changes when the Firefox version is changed). After you enter the Slackware string with either about:config
or in prefs.js
, you can see the change the same ways.
Then it's no great trick to double-click on the displayed user agent, exit Firefox, edit the prefs.js
file (or about:config
) and insert that line as shown above.
This is, of course, only if you give a hoot about accurately presenting your user agent to a web site; only takes a couple of minutes to do and, as always, YMMV.
Hope this helps some.
