NoScript and AdBlock work fine. So does TabMixPlus. A couple of other extensions I use are broken, but I can live without them, at least temporarily.
The feature I like the most is the ability to hide the menu bar (with “File Edit View History” etc.). If you need it, you just press alt and it appears. A little extra screen space is always welcome.
I dislike the way they’ve changed the cache. Before, you could just go to the cache to copy a YouTube file or other files. No more. They deliberately did this to defeat the copy trick. Boo!
I’m, using Firefox 4.0.1 and find it a little buggy. I have some news pages set up to open in several tabs via a one click option from Bookmarks. However, if I’ve had the browser open and have been to other sites before using this one click option then the news tabs fail to open. I have to close Firefox completely and reopen before this feature works.
I’m for going forward, not backward. I moved to 4.0 because the older version, with the latest update, refused to play YouTube videos. Version 4.0 cured that problem, but really ate memory. The new 4.01 seems better, but they still have bugs. All my add-ons work including No Script.
It looks almost exactly like Opera now. Seriously, when I first installed and ran it, I thought I was running some customized Opera skin. I don’t like that. IE, Chrome, FF and Opera all had their own look, and FF changes the skin to mimic one of their minor competitors? Lame.
Does it have a title bar? That’s one thing I hate about Chrome, often there is useful information in the title bar and the tab isn’t enough to hold that text.
I liked it the first day. I hate it now. Most of my extensions upgraded, but I had to install new ones just to do/not do things Firefox used/didn’t use to do. I’m annoyed that it only lets you have one “new tab” button. Before you could have one in the tab bar and I had customized a toolbar and added an additional button. Now? Nope. I’m sure there must be some crazy elaborate work around, but I am not getting the logic of disabling minor things like that.
Mine leaks memory like a sieve too. From what I’ve been able to tell, it’s most likely some conflict with Flash. Not everyone has it, but a lot of people seem to. If I watch a lot of streaming flash movies or have my browser open for long periods of time, especially with lots of tabs, it’s like I’ve gone back in time with the speed of the browser. I can’t necessarily blame FF if it’s an Adobe issue, but it’s still annoying.
Currently using quarter of a gig for 14 tabs. I restarted it about half an hour ago. In an hour or so that usage will be up to around a half gig. This is a 4GB machine.
I like it. I gave it a test run at a temp job so I didn’t have to commit to it at the home office if I didn’t want to. It took a while for all my add-ons to catch up, and last I checked you still need to download a user-modified version of 1-Click Weather (listed in the comments of the add-on page) because the one offered on the add-on page/created by Weather.com doesn’t actually work, and as of a few weeks ago they still hadn’t fixed it.
Most of the cosmetic changes were easy to get used to. I like the idea of the tab manager, but have yet to find it incredibly useful. I love the “pin tab” feature – I keep Pandora up there permanently, and it takes less real-estate than just setting it as my home page. I did rearrange the buttons on the navigation bar at the top, since I prefer bookmarks and homepage buttons over on the left by the arrow buttons. It makes more sense to me, since that’s where the drop-down menu is, too.
If you want to check your add-ons, there’s a FF add-on called “It’s Compatible” that will show you which of your add-ons are compatible with which versions of FF.
It’s OK. I like most of the new changes. The no saving tabs for later thing doesn’t bother me because I’ve always used the ReadIt later extension.
However, I disagree that it’s better with Flash. Some videos on youtube look like the blocked porn channels from my teenage years. I’ve been unable to fix it and I have found myself using Chrome more than before for more than just videos.
I’ve not noticed any performance issues, really. Totally not seeing anything weird in the anti-aliasing, and I did try the anti-aliasing add-on at the temp job (no noticeable difference), and haven’t bothered with it here.
I don’t get all the hate…of course, I switched from Internet Explorer to Firefox 4, so of course I think it’s an awesome browser. There are a handful of sites (for example, the printer/scanner addresses on the office network) that require the IE tab add-on, but overall I haven’t had problems. My work computer is old and slow; besides a slightly sluggish program start-up, I haven’t noticed any performance issues.
