Hey guys, one question. Let's say I got one New Tab Page opened and I want to open 3 sites from a folder. I right click the folder and select "Open all in Tabs", but when that happens I will have 3 tabs(the 3 sites I opened) AND the New Tab Page. In older versions of Firefox/Nightly, one of the 3 sites would be opened in the New Tab age, thus having 3 tabs opened and not 4. Any way I can fix it with a simple addon or inside the "about:config"?

Since about Firefox 33 I have been getting horrendous performance from Firefox it constantly freezes(flash crashes alot more than usual), sometimes it stalls for an entire minute then it will become responsive only to stall again a few seconds later. Also the tab graphics & even the web page content will all brake sometimes. For example I might close a tab but the tab graphic won't go & will start to brake, resizing the window usually fixes it.

 

I mean it generally works more than it doesn't, but Firefox really feels increasingly sluggish to me.

You updated to 33.0.2? Try Firefox Beta to foresee whether it got fixed in upcoming version or not.

Mozilla have decided they're only going to support 64bit builds on 7+, people still on Vista or XP are going to be stuck on the 32bit builds until they get their systems up to date.

Great! I quite like this change. I don't foresee 64-bit Firefox working too well on XP 64-bit box.

Hmm, so they are leaving out quite a large chunk of their users, because I remember the Windows XP netbook craze during 2009 & 10. :/

That's the problem. Those netbook users will eventually be stuck with an older version of Firefox.

it's not like they're dropping support for the 32bit version of firefox

Yeah, what they said.

32bit builds will continue to be available, but if you want to run a 64bit build you'll need to be running 7 at least (Because nobody cares about XP64, or Vista for some reason). As an upside the 64bit build can then have any conditional "Is this API available?" code removed and just rely on the new APIs introduced in 7.

The Servo layout engine is Mozilla's experimental project written in the Rust programming language and seeking for a high level of parallelism in the rendering and layout of web-pages. While there's not yet any firm plans to replace Gecko with Servo inside Firefox on the desktop, the new engine continues to be developed and was talked about a few weeks back at LinuxCon Europe 2014 in Germany.

Aside from talking about the usual Servo points with the work done by Mozilla and Samsung, some new performance numbers were shared that show how fast Servo is relative to Gecko when it comes to handling web-pages:

Mozilla's Servo Engine Is Crazy Fast Compared To Gecko

Rendering CNN's web-site was much faster with Servo than Gecko, even when just running Servo with one CPU thread.

Handling Reddit is also much faster with Servo than Gecko and blew way past Gecko when using its multi-threading abilities.

For those wishing to embed the Servo Engine within their own applications for web rendering, Servo seeks to have a stable API/ABI, will be a C-based interface, considered "flexible" by its developers, and has already been largely designed.

In 2015 the Mozilla developers might try embedding the Servo Engine within Firefox Android and Firefox OS, but there's not yet any plans for using Servo to replace Gecko within Firefox or Thunderbird.

The Servo road-map the 2015 plans include releasing an alpha-quality browser using Servo as its rendering engine, landing a Servo component authored in Rust into Gecko, and implementing more features.


The LinuxCon Europe 2014 slides about Servo can be found in PDF form.

Servo really is quite cool, I'm not sure if it will replace Gecko, but it's always possible (Only reason you want to keep the old code is to avoid re-implementing everything and introducing bugs, but if you're doing that anyway?)

Good afternoon :)

 

I had a total of 3 addons for the last few years,  Xmarks, Adblock plus and flashblock! I'm currently using 33.1.

 

So last week I ditched Xmarks and started using Firefox Sync in hope to get a more responsive and faster Firefox, namely trying to get rid of 1, 2 seconds to load each page, where without add-ons is almost always instant.

 

Noticed a bit of more responsive UI.

 

Now I'm wondering if there are better alternatives to adblock plus and flashblock. I don't really use any advanced options of adblock plus or in flashblock, I only block flash and not even HTML5!

 

So what alternatives with performance in mind are available?

I'd recommend adguard over adblock plus . Noticed better page performances with it.
And do you really need flashblock? I'd just get rid of it, as I noticed less and less sites use flash. In my surfing I only see two sites that use flash. Twitch and YouTube.

Click to Play - in case of Flashblock or try this alternative addon though with some limitations:https://addons.mozilla.org/en-US/firefox/addon/flash-control/

Adblock Plus replaced with Adblock Edge - https://addons.mozilla.org/en-US/firefox/addon/adblock-edge
