It's not particularly that 3.5 is slower in general, it's just slower at what I need it to do. I don't know if it's just me, but try opening 100+ unique tabs. Then, tell it to bookmark them all. Now watch it sit there for about a minute or more.
Do you know of a browser that doesn't lag when you try to bookmark 100+ tabs? Because I don't.
I don't understand why it would. All a bookmark is... is a link. If you save an HTML file full of 100 links in Microsoft Word, would you get one minute worth of lag? No. That's retarded. I've actually looked at what the bookmarks file in your profile looks like (I've been transferring this profile I'm using across some number of computers now), and all it is is an HTML file. If Firefox has that much trouble appending some 100 categorized links to it, on a good processor, then I think they need a restructuring of that piece of code, because it must be horribly inefficient. I mean, all it does is add a new bookmark folder and shove them all in there. There's something wrong here.
As for your question, I don't know of another browser that has the capability to bookmark all tabs, so I can't test it out.. though I imagine if I could do it with Google Chrome, the results would be better.
Well, you can't do that in 3.5. Apparently, there's this funny little thing they implemented where there's an invisible divider that determines whether the link you just dropped down on the toolbar will go to the VERY BOTTOM of the dropdown list instead of the very top. This is annoying as fuck. Imagine having like 300+ links in your toolbar and for some reason the links you're trying to put at the top of the list just magically end up at the bottom.
Open your bookmarks, press the home key to navigate to the beginning of the list, and the end key to go to the bottom. TIL.
That's a workaround. There's no excuse for something this counterintuitive to be in the program to begin with. Also, if I just take a random distribution of links and scatter them across the top and bottom of a list, how much less efficient do you think it's going to be, each time, to have to go to the top and bottom of the list to try to find what I'm looking for? A hell of a lot, eventually (though, it's not "eventually" in my case, it's more like I'm already there). Moreover, some of these links aren't necessarily things I'm "looking for". Often times I just go to the bookmarks list to look for mangas that I'm interested in checking for updates. I'm not going to know any specific names, or what I'm searching for, so if one of them just randomly got put on the bottom of my list, it's may, for all practical reasons, go unread forever.
I'll concede that my specific problem is probably not very common, but the fact that the thing functions like that in the first place is something that has absolutely no good excuse.
I may try filing a bug report and seeing if they pick up on it.
Edit: And by one minute worth of lag, I mean the program stops responding ENTIRELY. It's not just lag, it's like it locked up.
