10.3.3 console hangs on many operations after upgrading to FF 8, not IE 8

Question

I've had WebLogic 10.3.3 installed on my laptop for quite a while. I have an AdminServer in a domain that I start every few days. Over time I've edited config data in the WebLogic console many times. I almost always use Firefox.
A couple days ago I upgraded from Firefox 7 to Firefox 8.
This morning I discovered that the admin console was behaving strangely. I was trying to add a new datasource. When I clicked on "New" it gave me the watch cursor and never changed. My CPU was low, and the tailing of the console log didn't show anything out of the ordinary. I eventually canceled the operation by clicking on a different entry in the left nav. I tried again, with the same result.
I then tried to deploy a new application. I got to the directory with my EAR file, and I clicked the radio button for the EAR file, and clicked Next. Watch cursor. Nothing happened. I tried this again. Same result.
I then manually killed the server and restarted it, then tried both of these tests again. Same result.
Then, I thought perhaps this had something to do with Firefox 8. I first tried bringing up IE 8 and started down the app installation test. No problem. I didn't fully install the app, but it got past the point that I was blocked with Firefox 8. I then tried using my Firefox IETab plugin to change the rendering engine to IE, and I tried the datasource test case again. Also no problem. It let me create the datasource with no problem.
I guess I'm going to have to figure out how to revert to Firefox 7.

II have a similar problem.  After installing 8.2 on my iPad3 performance is much worse.  In Safari, some pages seem to take 2 or 3 times as long to load and I have gone from feeling my iPad is quick and responsive to feeling it is sluggish.  Also, I have a lot of raw photos in the photos app that were loaded via the camera connection kit when I was on IOS 7.  It used to be great browsing them - very snappy.  Now each image takes 7 to 10 seconds to render - unusable.  I had an Apple Genius check it out, and he ran diagnostics and found that a process that renders images was crashing, and advised that I do a clean restore via ITunes which I Did.  Web browsing seems a little better, but still slow.  The slow renedering of raw images in Photos is unchanged - still 7 to 10 seconds.  Called Apple support who ran diagnostics again and said all was O.K.   Only suggestion was to restore software again, but this time don't allow restore to restore any data to create a completely virgin installation.  Haven,t done this yet, but not very hopeful.  Very disappointed - should never have upgraded, and of course you can't go back.  Been using Apple stuff for 30 years, and I think the fact that Apple will not let you install a previous version is one of the things I like the least.  If anybody has any ideas, they would be appreciated.  I do plan to try loading a new raw file into Photos to see if loading raw files on IOS 8.2 gives a different result.
