User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050414
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050414

This is actually a problem that I have observed for quite some time now:

Whenever I keep Mozilla running for more than 2-3 weeks, the clipboard becomes
unavailable/unreliable in Mozilla, basically I cannot copy/paste anything
from/to a webpage - except if I'm trying to paste contents that I have copied to
the clipboard using a different application - this applies to the navigator
component as well as all other Mozilla components (composer,mail etc.)

I can easily reproduce the same behaviour within *hours* if I use multiple
Mozilla windows at once with numerous tabs open, i.e. 5 windows and about 120
tabs total.

(BTW: in that regard it would be very useful if there was a scrollbar for tabs ;-)

Likewise, after about 4-5 weeks, Mozilla will either crash totally - or won't
quit at all (5-10 zombie processes)

I have observed this behaviour with either, the static build as well as custom
builds from cvs/source.

So I think that this is somehow related to the underlying memory management
code, however the machine is fully capable of dealing with the described load (>
1 GB RAM) Also, the behaviour does NOT occur with any other applications on this

I'm currently using Mozilla 1.7.7, I would copy/paste the full information from
Help/About *if* my Mozilla-clipboard hadn't quit working  ;-)

Reproducible: Always

Steps to Reproduce:
see above, but for example:
1. bookmark 20-30 webpages as tab group
2. open this tab group in 3-5 different browser windows
3. wait some time
4. try to copy/paste within mozilla
5. => enjoy :-)

Actual Results:  
Usually, the clipboard won't be accessible within Mozilla - i.e. I would not be
able to copy anything from a webpage, however PASTING contents from other
applications to Mozilla would still work

Expected Results:  
copy/paste as usual :-)

The problem seems only to occur when Mozilla is either extensively used or when
the same instance is used for a relatively long period of time (i.e. Mozilla
instances that were started several weeks ago won't work reliably)

I'm seeing this or a very similar problem, but on Win98.

More specifically:
* Mozilla/5.0 (Windows; U; Win98; en-GB; rv:1.7.10)
* Gecko/20050717 Firefox/1.0.6

I noticed it after trying to make a screenshot (Windows
places one on the clipboard when you press PrintScreen)
illustrating a more serious Firefox display corruption
problem.  The screenshot turned out to be even more
corrupted than the display - and black-and-white on top
of that.

The Firefox display-corruption problem is the most
common reason for rebooting an otherwise stable Win98
session - many other applications still work properly
at the time.  I've been experiencing it for quite some
time, and have suspected the cause to be a memory
management problem in some component of (or relied
upon by) Firefox.  

I have a debugger running (Soft-Ice), and at times
that the above symptoms appear, it reports something
about LogError ERR_GALLOC - apparently an error
condition that may be returned by the Windows API
function GlobalAlloc().

I'm not particularly familiar with either X11 or
Windows programming, nor with the Firefox source
code, but if there's any system information I
could monitor or debugger tricks I could try in
order to further our understanding of this
problem, I might be able to help.

bug 244598 is similar to this one
Mozilla 1.7 and Firefox 1.0.6 are obsolete by now. I'm not seeing this in

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9pre) Gecko/2008060701 SeaMonkey/2.0a1pre

Does anyone still experience the bug with a recent build (and which one) of Firefox or SeaMonkey?
