updates Meet the browser: Firefox Next

[LimeMaster]

...not really. in my experience 99% of fx mem leaks are an issue with an addon or plugin. I haven't had mem leak issues on firefox on any of my machines for years.

 

The versions of firefox known for mem leaks are older versions (1.x-2.x, most mem leaks were plugged when 3.x was released), not modern versions.

You're right! My issue was caused by an extension. However, before I posted in this thread, I had been having this issue since Firefox 29 and looking up the issue most sites said that the leak was introduced in recent versions of Firefox. Unfortunately a lot of sites failed to mention that it was certain plugins or extensions that cause this issue.

[Boo Berry]

If I were you I'd try a clean profile. I always do with every new version of Firefox and Chrome for that matter.

[The_Decryptor Veteran]

This is where about:memory helps, shows what is using memory and how much (An actual memory leak should bloat the "heap-unclassified" value, otherwise it's just bad memory management)

[BooBerry]

Does ver 35 break for anyone else when

dom.indexedDB.enabled = false ?

Is the a known bug?
Can someone file an appropriate bug

[The_Decryptor Veteran]

Yeah, don't disable indexedDB, stuff probably relies on it.

[+Zlip792 MVC]

D2D 1.1 landed in Firefox, hopeful that it will improve performance but high peak memory usage + slow scrolling regression bug has been filed by Alice already. Lets see..

[BooBerry]

Yeah, don't disable indexedDB, stuff probably relies on it.

 

But breakage is only on windows

WIN 64:

Although I don't cover Build Configurations related bugs but:

[The_Decryptor Veteran]

The 64bit Windows nightlies have started being signed, that was one of the biggest remaining hurdles to having official 64bit builds for Windows. There was no way Mozilla would ever officially support an unsigned version of Firefox, and their previous codesigning tools just didn't work with 64bit binaries on Windows.

It's once again interesting to see how quickly Firefox's UI adapts to a new OS X release compared to Windows, where it is still not completly updated to Windows 8, which was a few years ago.

All they've done for Yosemite is switch out the toolbar icons and make the sidebars "vibrant", they've done more for the Windows 8 variant (Which was only ever going to be a slightly changed version of the 7 theme)

Win 64-bit JS Engine JIT:

...

I didn't notice this had landed until I updated my nightly, but this was one of the other remaining blockers for 64bit Windows builds (It's almost as if Mozilla want to start shipping them)

Before this fix, crashes inside "JITted" JavaScript code wouldn't "crash properly", and the OS crash reporter would be called instead of the browser crash reporter (Bad, because that's what submits crash reports to Mozilla, and if they don't know about crashes they can't fix them). It turns out Chrome had the exact same problem with their 64bit builds, and both groups fixed it around the same time :laugh:

I think at this point they're ready to start testing the 64bit builds, and fixing any small issues that arise (Along with switching to VS2013)

I think Stub Installer (like of Google Chrome installer - Online Installer basically) already can do this.

...

That'd be where they do it, they just don't need to at the moment since there's only a single build.

It'd be interesting if they could automatically update users on a 64bit OS to a 64bit build, really the users install isn't what's important (Their profile is) so you should be able to remove the 32bit build and install the 64bit build without problem, but I think in practise we'd see a lot of crap installing themselves into the Firefox directory and then breaking (That's the problem they hit with 32, random apps had modified the support files and broke 32 from launching)
