59 tabs!?

I opened up up 25 with no problem in the 64bit dev edition and used less than 500MB I got a i7 8 gigs with a 4 gig video card

I opened up a little less than that in 32 bit FF and almost 600MB of ram

Note Mozilla Firefox is 64 bit on 64 Bit Macs, and probably 64bit on most Linux distros. ~J99

The memory usage highly depends on the page content (a lot of large image need considerably more memory).

You can try to use the "Free Memory" feature on the about:memory page to see if that helps to reduce the memory usage.

You can check for issues caused by plugins and set plugins to "Ask to Activate" on the "Firefox menu button/Tools > Add-ons > Plugins" page.

• plugins are not affected by Firefox Safe Mode

You can check for problems with current Shockwave Flash plugin versions and try this:

• make sure you have the latest Flash version:
  http://www.adobe.com/special/products/flashplayer/fp_distribution3.html
• check for updates for your graphics drive drivers
  https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration
• disable protected mode in the Flash plugin (Windows Vista and later)
  https://support.mozilla.org/kb/adobe-flash-protected-mode-firefox
• disable hardware acceleration in the Flash plugin

• disable hardware acceleration in Firefox

I will check it out. It is a bit tricky do get to settings as Firefox would sometimes crash 10 times in a row before I can get to settings.

I also tried Watefox 64bit as suggested in other posts, but running it on Wine causes too much memory usage with only 5 tabs open.

In the mean time I have been using Opera with no problems at all. I just need the browser to work out of the box.

My question is. Are the crashing related to too many tabs open at the same time?

Without being able to see the crash reports, we have no idea what is causing them or if it is related to memory usage from too many tabs, malware, an add-on, etc. There are 1000000 things that could be causing it.

I posted crash reports as requested.

Thank you for the crash reports. Some of these are so fast that I don't think the number of tabs is relevant.

For others that occur after the first minute, I doubt that the number of tabs is a big issue, particularly if you keep the default setting of only restoring the last active tab in each window. But simultaneously loading 59 pages would put some stress of Firefox...

Anyway, the majority of the crashes seem to occur in the JavaScript engine and/or "garbage collection" which is part of Firefox's memory management. These are not "out of memory" errors (or at least they do not have the hallmark of such errors on Windows).

Could you test in Firefox's Safe Mode? In Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Our support article "Diagnose Firefox issues using Troubleshoot Mode" says to run this in the Terminal (as a Windows user, I'm assume you have a better idea than I do of how to do that):

firefox -safe-mode

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?

Thanks for the info. I did this and 15 minutes later no crash yet. What is the next step?

Firefox's Safe Mode does a number of things which also can be switched individually:

• Deactivates all extensions
• Disables hardware acceleration
• Disables the "just in time" JavaScript compilers
• and more...

Before leaving Safe Mode, try disabling Firefox from using hardware acceleration:

"3-bar" menu button (or Tools menu) > Options Whoops, on Linux that would be Edit menu > Preferences

In the left column, click Advanced, then along the time, click the General mini-tab.

Uncheck the box for "Use hardware acceleration when available" and this will take effect when you exit Firefox and start it up again.

Does that improve stability in regular mode?

Also make sure that you have the latest updates of all packages like GStreamer and FFmpeg

You can try to disable GStreamer support and set this pref to false on the about:config page.

• media.gstreamer.enabled = false

Thanks for the info. I have disabled hardware acceleration and after this Firefox crashed about 5 times over the first 40 minutes. bp-98265380-efef-42d8-8f98-2836a2151208 bp-dc4da2f2-585e-4c27-9369-c49f62151208 bp-269b298d-7d8e-4586-86ae-889f42151208 bp-ec807bf2-532c-4d1f-870f-26d262151208 bp-f88992ee-7835-4a9d-b3e0-d56832151208

Phew thats enough for the day. Firefox does does run long enough so I can get to the config. Will try again later.

So I never really got this problem solved. Firefox still crashed too often. I tried Opera as well, but had similar issues.

As I am typing here, I have 79 tabs open in Firefox. This is a new method I were trying out and did not have crashes for no reason yet after about 2 days.

What I have done, is run the latest Firefox on Wine in my Ubuntu. It might be milliseconds slower than the native Firefox, but no crashes. The only crash I had this far, was when I downloaded a few big TV series from my web server on the same LAN using this browser.

Not sure why, but does this mean that the "Windows" version of Firefox is more stable. Keeping in mind that I use my Mozilla account meaning all the same plugins, bookmarks etc. is sync to this Firefox on wine. Or did it just need some wine :-)

You can try to disable GStreamer support and set this pref to false on the about:config page.

• media.gstreamer.enabled = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

• http://kb.mozillazine.org/about:config

user.js or prefs.js:

user_pref("media.gstreamer.enabled", false);

Think I`m going to stick with Firefox on Wine for the moment. I have 86 tabs open and no crashes since my last post.

I do not see the media.gstreamer.enabled

Apologies. I might have been looking at Firefox on Wine. Will check again.

I have changed this setting "media.gstreamer" to disabled and my Firefox on Ubuntu did not crash yet after 4 days with about 55-70 tabs open. Hope this solves my issue. Thanks

My system is an i5 with 22GB RAM running Ubuntu 15.10

I am a lightweight helper but I wonder if you could avoid that by opening 10 tabs and then open another window of Firefox, 10 more tabs and then aother window of Firefox, etc. ..... I said I was lightweight. Something to try until someone with real Firefox smarts comes alone! ":-Dx lol
