Following DjLizard's help in this topic http://forum.CCleaner.com/index.php?showtopic=844
he has asked me to post about this here, so here I am.

Not sure what info you need so if you need more please do tell me what you require.

Basically after running CCleaner and clearing out everything including the registry issues I could no longer access my Yahoo emails using Firefox.

After signing in I just got a completely blank, white screen.

Now with DjLizard's help I can do this although the page layout is incomplete.

Hope this helps and please do ask for any further information that may assist.

I have had this problem before, but CCleaner did not cause the problem. It was just yahoo's server.

We're able to actually cause the problem using CCleaner. Right now, on this computer (at my workplace) I can cause CCleaner's own forums to appear screwed up (if I allow CCleaner to clean Firefox's cache). Same thing for me at home, and several of my customer machines.

Simple solution: run CCleaner twice. I've had this problem before with Firefox and CCleaner. All you have to do is run CCleaner twice, ie., press clean, then press clean again, then again just to be sure . It should work after you do that.

Then there remains a bug in CCleaner if it takes two cleans

This error occurs if you have Firefox running at the same time you run CCleaner. As it still thinks some of the temporary files still exist. I'm looking into a work-around for it.

Hmm. I see...

Didn't think of it this way, but I'm using Firefox preloader, which keeps it loaded even when it's not open.. so that explains a lot.

Yes, put at least the temporary solution will tide us over until we can get a patch

I tried the temporary solution on my WinXP Prof. w/ SP2 and 'clean' several times with FireFox 1.0.2 still running and it does not work--blank Yahoo mail page (make sure you are inside the Yahoo mailbox).

The only *sure* workaround is to go into FireFox Options->Privacy and manually clear the cache. Then the Yahoo mail page reappear properly.

Pretty annoying--as I use FireFox extensively now on all my PC's. Hope the fix comes out real soon.

Close all browser windows and THEN run CCleaner.

Thanks Tarun!!! You solved my problem. "Close all browser windows and THEN run CCleaner." Open their eyes and the blind shall see! Now - how are the brainless made to think? Thanks again!

Sometimes the most simple solution is the most obvious one.

Or in the case the one right in front of your eyes. (Even as you read this message!)

On any java type page if you runn CCleaner and do not reboot it will wipe out the forrmating, I do this all the time to kill flashing adds.

Just run CCleaner with all browser windows closed.

R.I.P.

These threads are dead DRVTACH, if you'd read them you'd have noticed we've posted the solution several times throughout this page. (You attacked me in another thread for supposedly not *reading*, yet here you are, not reading).

Sun Java is not Javascript is not a GIF is not a Flash animation

Unfortunately, the manual cache cleaning is the only solution for me personally because of the following:

1. I need to run CCleaner in an automated/unattended fashion. Currently I set up a Windows scheduled task that is executed every night on all my PCs.

2. I need to keep all the FireFox browser windows open without interruption at all times as I have lots of work tied to the tabs in the windows that I don't want to close. The FireFox tabs feature is what really caused me to switch browser as I can have many tabs accessible without cluttering the desktop. Closing the browser windows means I will lose all my work.

Thx for the tmp workaround but unfortunately it doesn't help in my situation.

Try to run CCleaner on startup using the /AUTO command.

I tested this myself. Not only did I have missing graphics, my modem couldn't dial up afterward. I had to do a system restore.

Ok that's just plain absurd.

I concur.

I know it sounds absurd, but it's what happened. I tried to reconnect 3 or 4 times, kept getting the same error message, one I'd never seen before. I wish I'd written it down, but I was in a bit of a panic. I was prepared for Firefox to get messed up, had backed up profile and saved a copy of the setup file so I could reinstall the browser easily. I was totally dumbfounded when this happened.

Post hoc ergo proctor hoc. (because of this, then that) fatal error! Might be an unrelated problem, more than 1 problem, or all of the above.

If experimental results can't be reproduced, they're meaningless, so I guess I'll have to try it again - as soon as I can work up the nerve. I'll post the results afterward, so stay tuned.

Well, I tried it 3 more times, and I was not able to reproduce the problem with the modem. The problem of missing graphics was consistently reproduced, however. It didn't just affect the site I was connected to when I ran CCleaner (this one) either. Running it again after disconnecting did correct the problem. Cleaning again while still connected didn't help. So it seems my inability to dial up after my first test was a fluke, or a coincidence. I've been told by a couple of users that they run CCleaner while online, with no problems. So it doesn't affect all systems, is easily reversable, basically not much of a problem. Of course, I didn't try running the "Issues" scan while online, I'll leave that to somebody braver (or stupider) than me.

Greenknight I'm glad you solved your problem... I have pretty much the same problem as you... however, it turns out that just running it several times fixes the problem... we should make a topic thens sticky it....

It wasn't really a problem for me, it never would have occurred to me to run CCleaner with any programs open. I normally run it just before I shut down the computer. I saw some posts on the Mozillazine forum from Firefox users who claimed CCleaner had messed up their browser's display. I found this hard to believe, but since I often recommend CCleaner, I thought I should look into it. I'm just glad it turned out to be so easy to fix!

Yep, I was dumb enough to run CCleaner with the mailbox open and online, my mail page on Yahoo was blank - tried IE and it was there. Firefox: Tools/Options/privacy - clear cache fixed it fine, no need to re-run CCleaner.

AND - Greenknight I support you. My modem kicked off suddenly. It was a day later so it does not count as clear proof, but it has never happened before. It would not reconnect (redialed but then nothing) in several tries. I turned off the 'puter and came back next day -all was well.

SO - I would recommend a screen upon opening the program to remind those who should know better to turn off all programs and modem before beginning.

And thanks for the program. There is a noticable improvement in start-up time.

You have got to be kidding. CCleaner does NOT touch your HARDWARE in any way except for the hard drive which it cleans files from that and unneeded. It simply removes files from the hard drive by CLEANING out what is JUNK.

Your modem kicked off. Oh my god, please tell me you've heard of.. *gasp!* ISP's going DOWN for some time or even dropping connections!

Dropped connections happen all the time. It's a COMMON occurance, especially if you use a free ISP such as Juno or NetZero for their free service. After 10 hours they cut you off and you can't get back on, as you'll get a weird error message.

Trying to tie those things in to software that works fine can cause paranoia. Is that what you want to do? It was a freak coincidence. Next time stop and think logically before you get yourself in a panic.

I admit, I had a good laugh over this. So did my PC Hardware & Troubleshooting professor, along with the rest of the class. Anyone else find it amusing?

Phone lines are crap. Face it. They were usually installed in neighborhoods anywhere between the 40s and 70s, and they usually don't change much over the course of 50 years [as far as upgrades and maintenance]. Also, as Tarun said, the other end could have dropped -- after all, it is a computer too. Phone lines use only two wires to send and receive, and neither of them is a grounding wire... and they are not insulated, either. Line noise is going to happen. Dropped connections are going to happen. There is a modulated analog signal which is 100x more sensitive to noise than a voice phone call is. It's insane to even think that a modem drop has to do with deleting a few temporary/miscellaneous files on your computer.

I have to agree, dropped connections with dialup are commonplace. If it never happened before you must have exceptionally good phone lines.

The ISP would have to be quite good as well.

I too experience this bug and am able to reproduce it 100% of the time with every Firefox version (0.9 through 1.0.4):

1) Visit CNN.com
2) Have CCleaner clear Firefox cache
3) Reload page

You'll notice the CSS stylings have been lost and page reloads won't restore them. Only closing out the browser will reset things to normal. I've also experienced entire websites no longer loading after performing a clean with CCleaner while Firefox is open.

The advise of closing the browser before cleaning, while valid, is inconvenient.

admin, you may want to look in to the X 0.6.3 cache cleaning firefox extension:
http://www.extensionsmirror.nl/index.php?showtopic=130

It's capable of clearing the Firefox cache while avoiding the bugs others here have mentioned.

When cleaning the cache via CCleaner the files in the following folders as well as the folders themselves are deleted:

Cache
Cache.Trash

When cleaning the cache via X 0.6.3 the folders are emptied instead of deleted. But here's where the greater difference lies... After the 'Cache' folder is emptied, the follwing four files are re-created:

Cache\_CACHE_001_
Cache\_CACHE_002_
Cache\_CACHE_003_
Cache\_CACHE_MAP_

The 4 files in the Cache folder are all reset to 4096 bytes. Getting rid of these four files without allowing Firefox to recreate them is what appears to be the cause of the display bug.

There's probably nothing CCleaner can do about this because the X 0.6.3 extension uses Firefox's internal cache cleaning routine, which is capable of avoiding this bug. Perhaps CCleaner can look into ways of recreating these four files after it performs a clean?

Another thing I noticed, occassionally while using the X 0.6.3 extension to clean the cache... It sometimes moves the cache files from here:

Cache

to here:

Cache.Trash\Cache\_CACHE_001_
Cache.Trash\Cache\_CACHE_002_
Cache.Trash\Cache\_CACHE_003_
Cache.Trash\Cache\_CACHE_MAP_
Cache.Trash\Cache\other_cache_files

...thereby leaving the 'Cache' folder empty. In these instances, the four files I mentioned were not recreated in the 'Cache' folder.

The original cache files and their sizes were kept intact. Closing the Firefox browser clears the 'Cache.Trash' folder though and the four files above are once again recreated in the 'Cache' folder. I don't know why it does that and haven't been able to faithfully recreate this scenario, but it's definitely occuring.

It seems that Firefox always must have the four _CACHE_*_files to exist in either the 'Cache' or 'Cache.Trash' folder to prevent display bugs.

Thanks for the detailed information!
