Firefox 15.1 stops responding for no apparent reason!

Firefox 15.1 stops responding for no apparent reason!

As the title says, Firefox 15.1 stops responding for no apparent reason!

I just did a re-format of my system disk and I re-installed Vista 64-bit on it. I have obviously re-installed everything from Windows updates to chipset, graphics and sound drivers. I also pulled down the latest and greatest version of Firefox which at the time is 15.1. So installed that too.

Every now and then Firefox just stops responding for no apparent reason. It looks like it is processing the request (after clicking a link etc.) but it then it's just a silence... nothing happens!

It doesn't even say it can't load the page and Windows doesn't even say that it has stopped responding. Not even after I click like crazy on the Firefox interface like different buttons and tabs and on the web page... not even then does it say "not responding" in the title bar of the window, which is usually the case when you deal with programs that are not responding immediately (you get that dialog that asks you if you would like to close the program or search for solutions online). Just nothing!... it's only quite and does nothing....

At the same time, all other programs are working flawlessly, such as the Explorer (Windows Explorer), or even Internet Explorer. And Internet connection is not lost!

I have no add-ons or extensions installed whatsoever. I just installed Firefox! I haven't even had the time to install Java yet. All I have is Adobe Flash player. That's the only extra. Otherwise it's in its' original form, default settings, etc, etc, etc.

Why is it acting up like this?...

I'm surprised that there even is such a thing as Firefox 15. This one came at the end of August, correct?

I have been on Firefox 14.x something before I re-installed Vista. For a good reason so! This is why I hate the new update model of Firefox and I don't jump on the next train (version) unless it's safe and I'm having compatibility issues with the one I use at the moment. This is why my first step after installing Firefox always is to disable automatic updates! I hate it when the software vendors are pushing out their latest software versions forcefully.

Frankly, I think this new Firefox version of yours is crap. It's not properly tested and it doesn't belong in the official release channel. This is more like a nightly build or something. It probably has some memory leak, despite the promises made by Firefox engineers that it will not have memory leaks and that it would be the fastest version of Firefox ever. I don't really need a faster browsing, I need a stable browser for reliable browsing. The speed of this Firefox version is close to ZERO! When it's not responding at all...

I have been a fan of Firefox since 0.8. I will be probably ditching this latest version and going back to an older version like 13 or 14 that's more closer to the reality and not in this fantasy world of fastest, greatest, latest, version this, version that, latest features. I just want a browser that works man!... I'm getting tired of Firefox. I may even ditch it altogether in favor of.... I don't know.... Safari?... Chrome?.... I might even go back to Internet Explorer after like 12 years of absence.

I just checked about:crashes and I had 20 crashes from 19:31 to 19:46. That's 20 crashes within 15 minutes! It must be some kind of record or something... do you need the report IDs?

they would certainly be useful in diagnosing the issue

Re: Firefox 15.1 stops responding for no apparent reason!

Here are all the report IDs, FWIW.





















Comments on the bug tracker suggest that this is caused by Adobe Flash player, or the lack thereof (in my case).

But how can Firefox crash because it uses the wrong DLL for Flash when Flash player has never been even installed on this system? The comments at the link above would apply more to systems where Firefox and Flash player is already installed and then gets updated, and the update doesn't work properly so that the old versions' DLL file is used (with Adobe to blame probably).

But again, this system has never even had Flash player installed! Firefox is unable to use ANY Flash version DLL file as it is none-existent!

Could it simply be that the lack of Flash player can crash Firefox or cause it to stop responding (because it doesn't really crash at all unless I force close it)?... because I have noticed that this problem has stopped or is at least more seldom since I installed Flash player.

Is there something I can do to prevent this in the future? Or should I just jump to the Firefox 16 beta?

Re: Firefox 15.1 stops responding for no apparent reason!

Hi Fractalogic, your "More system details" link indicates that you have (or had) the Flash 11.4 plugin installed.

Two suggestions:

(1) Try disabling the new protected mode in Flash 11.3-11.4, since that feature is currently being debugged. See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

(2) Try disabling Firefox's hardware acceleration. You usually need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

orange Firefox button or classic Tools menu > Options > Advanced

On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"

If you restart Firefox, do you see any improvement?

Re: Firefox 15.1 stops responding for no apparent reason!

please try to uninstall the adobe flash plugin from the windows control panel. afterwards manually delete any leftover files in C:\Windows\SysWOW64\Macromed\Flash and download & install the plugin again (uncheck the option to install the bundled security software):
