And now it looks like this:
The problem, as with most website "upgrades," is it's slow as molasses. Gone is the zippiness. Instead, we get a mobile site that's almost as slow as the regular site. So I boxed mobile.twitter.com with FoxBox to see if it helped, and I found something interesting. I get a paired down, much faster version of Twitter:
Then I went back to TenFourFox and used User Agent Switcher to change the user agent to an iPhone 3 and found the same paired-down site. Interesting, so it's a user agent issue. The iPhone 3 solution isn't wholly satisfactory as it breaks some other sites, but after some trial and error, I found that the user agent for TenFourFox 37 gives me the same stripped-down, fast Twitter, so apparently Twitter Mobile only gives you the new layout if your user agent is TenFourFox 38 or higher.
I wanted to change the user agent to v. 37 permanently so I wouldn't have to switch user agents back and forth between sites, but User Agent Switcher has a bug/feature where it reverts to the default version after closing a window. So I did it the manual way, which is to enter about:config in the address bar and press return, type useragent in the search field, right click on some white space and choose New --> String from the menu. Enter this for the preference name:
Then enter this for the string (no line breaks):
Mozilla/5.0 (Macintosh; PPC Mac OS X 10.4; rv:37.0) Gecko/20100101 Firefox/37.0 TenFourFox/7450
(UPDATE: I should add to revert to default, right-click on the preference and select "Reset".)
With this I'm all set, until sites warn me my version of Firefox is too old*, please update, etc., etc. Maybe by then there'll be some kind of site-specific user agent switching available, either built in or as an add-on. I'm sure Dr. Kaiser or somebody can whip that up on a lunch break, ha ha. (2ND UPDATE:
Anyway, this has been another episode of cling to PowerPC forever. I recently weighed my upgrade options, looking at a Mac Mini, a Macbook Air, and a Thinkpad, but I didn't find them appealing. With new Macs, I'd have to accept no Firewire, no Classic, no PowerPC support, not even Rosetta, and Apple's increasingly buggy software. With a Thinkpad and Linux, it'd be much the same.
I'll just stay right here in my lawn chair.
*this may also interfere with add-ons auto updating until you update the version string to a version the add-on supports.
