Firefox 3 – XP vs. Vista and CYA

My laptop at work runs Windows XP. My laptop at home runs Windows Vista Home Premium edition. I didn’t have a choice with the latter machine so I’ve been trying to reach some sort of truce with Vista since I bought the machine back in February.

My wife’s laptop also runs Vista, so if nothing else when she has a problem I have some clue how to deal with it. Usually, I’ve already been there on mine.

The reason I bring up that dreary subject is that I installed Firefox 3 on my work laptop first. As related in my previous post there was some consternation with add-ons that were no longer functional under Firefox 3. Other than that, Firefox 3 installed just fine and runs great now that the add-ons situation is straightened out.

Because things were going swimmingly on the work laptop, I decided to upgrade Firefox on my home laptop, as well. I expected the same heartburn with add-ons and felt like I had a pretty good handle on how to deal with it.

Silly me.

I ran the Firefox 3 installer and did not get the expected dialog listing the add-ons that no longer worked and the helpful “May I look for updates?” button. Instead, Firefox simply started up as usual and I was looking at the blank Firefox 3 interface.

I went to the Tools menu and click Add-ons to bring up the Add-ons dialog. I was greeted with a list of add-ons, most of which displayed the message “Incompatible with Firefox 3.” Some of them had the Uninstall button active, others didn’t. All had the Disable button greyed out along with the Options button.

I clicked the Uninstall button on one of the now-defunct add-ons. Firefox did its thing then displayed the familiar message “Add-on XYZ will be uninstalled when Firefox is restarted.”

I restarted Firefox. The browser came back up. I went to the Tools menu and clicked Add-ons. There at the top of the dialog was the add-on I’d previously uninstalled, its Uninstall button now greyed out, happily displaying the message “Add-on XYZ will be uninstalled when Firefox is restarted.”

Huh? I’d have sworn I just did that. Okay, restart Firefox again. Check the Add-ons dialog again. Same result. This is beginning to look suspiciously like an infinite loop.

After trying a few things and getting nowhere, I decided the better part of valor was to simply uninstall Firefox 3 and go back to Firefox 2 which had been working just fine previously. The result of that exercise was Firefox 2 coming up looking as expected.

Since I knew Google Browser Sync was dead, and I’d been impressed with Foxmarks, I figured I’d go ahead and install Foxmarks and make the switch now. I visited the Foxmarks site, clicked the Install button and got an “unexpected error -203″.

Mind you, this is the first time I’ve ever had an add-on install fail for any reason. Obviously, something was amiss. After some research, the consensus seemed to be that my profile was trashed.

Thinking that perhaps this was one of those Vista-isms where something should have been run in Administrator mode, I re-ran the Firefox 3 install as Administrator. Firefox 3 came up okay. The install of Foxmarks failed again with the same error message.

By now, it’s apparent that the only way to get Firefox 3 and its add-ons sorted out is to create a new profile. Now, mind you, had I thought to BACK UP my existing profile before starting this odyssey, I probably could have simply restored it and been good to go.

Ya gotta love 20-20 hindsight.

Creating a new profile solved the problem, but of course, I had to reinstall all the add-ons I wanted, not to mention redoing all my preferences since I couldn’t find a way to copy them from the old profile to the new one. I wasn’t real confident that it would have worked anyway since I don’t know what part of the old profile is still good and which is corrupted.

The moral of the story is, of course, to back up important things like your Firefox profile before upgrading things that might affect it. I get lazy just like everybody else, even though I know better, and in this case it bit me in the keister.

Was it Vista that caused the corruption? Who knows? It really doesn’t matter, it’s my bad for not properly covering my aforementioned keister and making sure I had a backup to fall back on in case things went awry. That seems to happen a lot more often in Vista than in XP, at least in my experience, so if you’re thinking of upgrading Firefox or any other software, for that matter, do yourself a huge favor and make sure you’re backed up before you start!
