The plans to ‘officially’ release a Win64 release of Firefox have now been pushed back to Firefox 42 (November 2015). As you may recall it was suppose to be Firefox 40 (August 2015) then was pushed to Firefox 41 (September 2015). The reason for the delay as described in Bug 1185532 has to do with the sandboxing feature for the 64-Bit Flash not working correctly.
Mozilla release an emergency update for the Firefox 40 branch on Thursday, August 27th with Firefox 40.0.3 release. This release addressed the following issues:
- Disable the asynchronous plugin initialization (1198590)
- Fix a segmentation fault in the GStreamer support (GNU/Linux) (1145230)
- Fix a startup crash when using DisplayLink (Windows Only) (1195844)
- Fix a regression with some Japanese fonts used in the <input> field (1194055)
- On some sites, the selection in a select combox box using the mouse could be broken (1194733)
- Some search partner codes were missing (1195683)
- Various security fixes
User should be prompted to update or can do so manually via Help > About Firefox or download and install the latest version via getfirefox.com. The next planned release is Firefox 41 on September 22nd.
I'm using Pale Moon but not because standard FF was crashing (I don't remember the last time it did), I just hated the new UI.
"A week ago, Mozilla shed some light on its future, laying out a plan on how the browser is going to dramatically change in the upcoming months. While most of us understood "Chrome extensions are coming to Firefox," it is not as simple as we all thought.Please God, Don't Let Mozilla Ruin Firefox - Softpedia
"... The Mozilla dev team has a pretty solid plan on how they can change the browser "always crashing" image, and even if we don't like it, this includes a severe and very profound change to Firefox's core code. ..."
Our hypothesis is that when you open a Private Browsing window in Firefox you’re sending a signal that you want more control over your privacy than current private browsing experiences actually provide. The experimental Private Browsing enhancements ready for testing today actively block website elements that could be used to record user behavior across sites. This includes elements like content, analytics, social and other services that might be collecting data without your knowledge.Once again, this leads into marketing about the Extension Signing how it is this great thing and is suppose to make users safer by not allowing unsigned extensions to be installed. After all Mozilla's philosophy is the user can't protect themselves and an unsigned extension is an unsafe extension. The reality is an unsigned extension is all likely a safe extension that developer can't get through or gave up on all the approval hoops. via Mozilla Future Releases
Consequently, we have decided to deprecate add-ons that depend on XUL, XPCOM, and XBL. We don’t have a specific timeline for deprecation, but most likely it will take place within 12 to 18 months from now. We are announcing the change now so that developers can prepare and offer feedback.Mozilla is trying to move add-on developers over to the newer WebExtensions API which is used by Chrome and Opera. This announcement has not gone over well some add-on developers including Christopher Finke who announced on his blog he discontinuing further development of his add-ons as a result of Mozilla's announcement. Meanwhile Bill McCloskey offers some insights on how add-on developers could make this transition and the possible short comings of Mozilla's plans. Another reason Mozilla is pushing towards WebExtensions as they are fully compatible with Electrolysis aka E10s (multi-process). While add-ons which haven't been upgrade to work with Electrolysis will still run, they are going to be forced to run in the current single process environment which will be slower. Mozilla still hasn't even determine when Electrolysis would be officially rolled out. The current target is with the Firefox 43 release in mid December 2015. Whatever the release date happens to be, Mozilla plans on killing support for add-ons using XUL, XPCOM, or XBL within 6-months. Finally, everyone's favorite add-on topic, Extension Signing was also
Starting in Firefox 42, add-on developers will be required to submit extensions for review and signing by Mozilla prior to deployment, and unsigned add-ons cannot be installed or used with Firefox. We realize that the add-on review process can sometimes be inconvenient for developers. Reviewing is a mostly manual, human process today, and moving an extension from the initial submission to passing a full review that meets our guidelines can be a time-consuming process that can take weeks or months. A major advantage of WebExtensions is that they can be reviewed more quickly. In general, it’s easier to develop a correct WebExtension, and the permissions system makes it easier to recognize malicious add-ons.I understand that the current XUL, XPCOM, or XBL architecture is over a decade old and their is new and better ways of doing things now. However, the timing of this (along with E10s and extension signing) is horrible. Add-on developers are already unhappy with having to jump through hoops to get their add-ons signed, but are now being told they need to re-write them as well to use WebExtensions to better take advantage of E10s (which has been in the works since around 2009 and Mozilla still doesn't have a firm date when it will be active) which will make the signing process easier. Part of the issue is Mozilla has put E10s on hold to allocate resources to other short term projects. E10s should have been fully developed and implemented by now so add-on developers would be able to see the advantage of using WebExtensions. What I can see is happening is add-on developers are going to simply abandon Firefox as Mozilla is becoming increasingly too difficult to work with. Since add-ons are the biggest part of Firefox this could mean the start of the death of the (desktop) Firefox browser. Of course, extension signing will already start the clock ticking next month with Firefox 40 (even though user can still over-ride the forced signing check).
"You can check if your browser supports all the codecs for YouTube by checking the YouTube HTML5 Video Player website, which list everything supported on your PC. If you have a Linux systems and Firefox 40, it's likely that some of those codecs will have a red sign, meaning that they are not enabled. All you have to do is open about:config and make the following changes. Please make sure that you don't change anything else. ..."Source: Softpedia

- New 'New Tab' behavior. Gone are the days users could set their preference as to what comes up when they open a new tab via the browser.newtab.url preference in about:config. Nope, that was being 'exploited' so Mozilla removed this functionality that has been in Firefox since Firefox 13 (June 2012). There is a simple solution, Custom New Tab add-on. Simple, but... Why should users have to add an add-on to restore (what now has become) core functionality to Firefox and at the same time why can't users add an add-on to add features that shouldn't be in the core functionality such as Hello, Pocket, etc.? This add-on does not require a restart. Once installed go into the add-ons manager click Custom New Tab and then Options.Simply place the address of the site you want to open (or leave blank for a blank tab) when you open a new tab. Place focus in URL bar - when you open a new tab, the specified page opens and your cursor is placed in the URL bar (after the page is fully loaded) so you type the address of where you want to go next without having to click in the URL bar. Make URL bar empty - when you open a new tab, the specified page opens and the URL bar is blank (warning: the URL bar is cleared when the page finishes loading and if you start typing in the URL bar before the page is done loading your text will be removed).
- Extension Signing/Verification. Been talking about this for a while now. You may have seen the warnings in your add-on manager with Firefox 40 if you have unsigned or unverified extensions. In Firefox 41, unsigned extensions will be disabled when you update and also won't be installable. However, in Firefox 41 you still turn off this
annoyingfeature via about:config and set xpinstall.signatures.required to FALSE. Warning: in Firefox 42 xpinstall.signatures.required preference will be ignored and unsigned add-ons will not be permitted.Mozilla can still 'make this right' by keeping the xpinstall.signatures.required preference active so that users who know what they are doing can continue to use unsigned add-ons. Just because an add-on is unsigned does not mean it is not safe. There are many developers who don't want to host their add-ons on AMO and don't want to jump through the multiple hoops with Mozilla to get their add-ons signed. This is especially true for corporations which may have proprietary add-ons, though they should be using the ESR version of Firefox which currently does not enforce extension signing.
- 64-Bit Windows Firefox. The plan is for Mozilla to release the first official public version of 64-Bit Firefox for Windows with Firefox 41. Mozilla's objectives on this is to make it more stable, efficient and safer compared to the 32-bit version. To do this, they have made a critical change in the Windows 64-bit (no changes with the OS X and Linux) version that removes support for most NPAPI plugins such as Silverlight and Java. This appears to be an industry trend as Microsoft Edge (Windows 10) browser has no plugin support (other than Flash) and Google Chrome is removing support for NPAPI plugins (except Flash) by the end of the year.With that said though, Mozilla needs to carefully consider how they 'disclose' this fact and market the Win64 version of Firefox. By disclose I don't mean bury it in the release notes which is likely what they are going to do. What I fear is Mozilla is going to make a big deal out the 64-Bit support and mention in very small print somewhere deep on the page: Netflix, Amazon Instant Video, Magine TV, Maxdome and an unknown number of other streaming and VOD sites worldwide will not work this version. Instead they need to tell users if you want to use Silverlight, JAVA or any other plugin technology this version is not for you, use the 32-bit Firefox version.
