Firefox 43 64 bit

[jkauff]

Easiest way to confirm you've got the 64-bit version is type "about:" in the address bar. All the build info is right there.

What's the purpose of a 64 bit browser when a 32 bit browser does the same.

In theory, building in 64-bit mode lets the compiler count on some extra registers being present in the CPU. It sometimes translates into minor performance gains.

What's the purpose of a 64 bit browser when a 32 bit browser does the same.

Because computers are 64 bit and have been 64 bit with 32 bit backwards compatibility for over a decade now. We need 64 bit Firefox for the same reason we needed a 32 bit Notepad. Eventually, we need to get programs all running in a 64 bit world.

Security is one reason. You gain additional things when moving to 64-bit such as HEASLR (high entropy address space layout randomization) and always on DEP.

FF 43 - more pocket ads, forces new search mode with single search engine (same as in Chrome).

I've finally stopped using it for good.

That seems more logical.

A far more direct way of confirming whether your version is 64-bit, run it, and run Task Manager to see whether its process is labelled as Firefox.exe *32 or just Firefox.exe.

IIRC Win10's TM doesn't tell you about 32-bit processes, so run Process Explorer, right-click on the process in question and click on Properties. 'Image' will say 32 or 64-bit.

Win10 task manager is the same basic thing as Win8 and it has (32 bit) marked next to 32 bit programs.

Hmm, installed into program files (x32) directory.

I can't believe that Firefox is now harassing me for donations every time I launch the browser now.

Thanks, but I've looked at their latest IRS filing, and they are making a hell of a lot more in income than I am. If Mozilla really needs more cash, perhaps they should stop paying their director $220K a year.

Anyone else seeing this? If so, it is a good reason to keep an older version.

Nope never seen that, btw mine just updated to 44.0b2 and still no issues.

Furry muff. I couldn't remember whether it did or not and I didn't have Win8x/10 to hand to check.

43.0.2 is out now (updating from the browser)

I wish that I would have made it up:

 

[balloonshark]

I wish that I would have made it up:

Mine opened my home page and a tab like in your pic. I closed that tab and removed a little bit of code at the end of my homepage url. I did this where you set your home page and everything works normal now.

To be clear my homepage is https://duckduckgo.com/ and I removed the junk that was after .com/

I have no idea if just closing the nag tab or removing the code fixed the problem.

 

[TeknoBug]

FF 64bit has been pretty good so far, good enough that I removed Waterfox.

But that donation nagging... what the f-, haven't gotten that.

I see this too.

Why my firefox is too slow and always hookup my PC?

Do you still use a Pentium 4?

 

[Mem]

Why my firefox is too slow and always hookup my PC?

Many reasons for example, malware on your PC, resource hog anti-virus software, corrupted Firefox profile folder.

44.0b4 is out for those on the beta channel.

It's a primitive browser that does all its heavy lifting in a single process. This is why the UI stutters/hangs when it's rendering a complex (or lots of simple) web page(s). See:

https://developer.mozilla.org/en-US/Firefox/Multiprocess_Firefox

In current versions of desktop Firefox, the entire browser runs in a single operating system process. In particular, the JavaScript that runs the browser UI (also known as "chrome code") runs in the same process as the code in web pages (also known as "content" or "web content").

Oh come on they have plugin handler running in a separate process

On a serious note, they use threads, albeit not optimally, because I never can see Firefox use more than one CPU effectively, not even when multiple tabs are loading.
