IE 8 Beta 2 Impressions

Internet Explorer 8 beta 2 came out just before Google Chrome, and both have several features in common.  However, Chrome is still built on a known-exploitable code base that even Apple had already patched in Safari, so I can’t take that seriously as a safe edge-facing product.  I also don’t like vendors who silently push updates without user control, who who are slow to tell you what their new code does.


Beta 2 feels a lot more new-featured than beta 1, partly because it is, and partly because the new UI is catching up with what is inside the code.  There’s enough difference and improvement over IE 7 to be worth a look, even if you aren’t interested in the beta testing and feedback process – but it is in beta, so take care if testing it your “real” computer.

I enjoyed the safer address bar URL display in beta 1, but there’s more URL-handling goodness in beta 2, especially when it comes to revisiting where you’ve been, keeping track of which tabs were opened from where, and so on.  There’s also the InPrivate mode if you don’t want your history retained.  And I love the new search entry area’s drop-down set of search engine icons, so I can change engine on the fly for each search instead of having to set and change this.

A subtle but significant joy is improvement of Standards vs. IE 7 modes.  In beta 1, one had to exit the entire browser to “change gears”, which seemed odd as each tab runs in its own process, including a mix of tabs in Protected and non-Protected modes.  In beta 2, you can not only mix Standards and IE 7 modes across a tab set, but have the browser remember and automatically apply the correct mode for a given site or domain.

It’s a bit strange to still have no “advanced” download support, i.e. the same ability to resume interrupted downloads that we had in the 386 era’s BBSs transfer protocols.  After all, ftp does as last embrace such things, as well as the ability to download from multiple points in the same file for speed.  Why should we still need tacky and often spyware-riddled add-on tools to do this?


On stability, it’s a bit of a mixed bag, compared to beta 1.  It now handles the Trend SysClean engine download link a bit better; it still shows the Windows executable code content within the misnamed .COM file as a web page, but no longer crashes and can Save As correctly.  Some other sites that didn’t work in beta 1, such as on-page UI buttons to send comments from some blogs, now work correctly in beta 2.

On the downside, IE still struggles to close when there are many tabs open (typically I have 20-30 open per window at a time), and can fall into a doomed loop of retrying the same page that crashed it.  I’ve also seen the whole browser become terminally unresponsive, and not always when trying to close down multiple tabs.  That can cause a storm of crash dialogs etc. if it tries to recover all the tabs that were open.

When the browser becomes unresponsive, I either see System and IExplore pegged at 50% CPU each, or (more often) > 90% of CPU time correctly in the idle loop, while IE still behaves as if it’s being hogged.

All of this testing has been on XP SP3 with IE8 running in Standards Mode, and set to prompt on active content.  That can lead to multiple tabs stalling on such prompts at the same time, which may bulge resource use or lead to some sort of race condition.  I suppress 3rd-party enhancements via the IE 6 era Tools, Options, Advanced setting, so there shouldn’t be any BHOs or toolbar code.

I’m certainly enjoying beta 2, but wonder whether there will be more builds to test between now and RTM.  IMO, there need to be, if only to pin down and fix the stability issues that remain.
