Hi,I use Windows 10 with mozilla firefox and for the past 3-4 months I have been having recurring problems with mozilla not responding and being really slow,hanging etc.

I have tried refreshing etc. to no avail....I have managed a couple of times to get it back working reasonably well then the same problem starts up again and I keep forgetting how I managed to fix it.

I have used other browsers in the past such as chrome and opera but have always went back to firefox and was thinking about trying a different browser again and so installed pale moon but I can't import my bookmarks and passwords to it.

I am not sure wether to persevere with firefox or try another browser as I am getting fed up with the slowdown problem.

Can someone tell me what other browsers other than chrome and opera to try out and what should I try in order to fix the problems in firefox?

How do you typically remove obsolete files from the user's profile folder? I mean, cache files, old and/or damaged .sqlite files, session backups, downloaded websites, crash reports, old dump files, minidumps,  etc.. Perhaps there is so much rubbish and damaged files so that they impede the normal operation?

For example the Firefox default enabled cache size is 358400 bytes, if You don't delete them, then Firefox cannot work any way, because it don't delete them itself and also will not over write nothing. User simply must empty this folder.

If You run regularly for example CCleaner, then it cleans what is primary necessary.

Most issues with Firefox originate in the user's profile, not in the program itself.

There are other, system issues (such as slow internet speed, security software conflicts, hardware issues) that will not be fixed by switching to a different browser.


Here are two tutorials for troubleshooting Firefox performance.

The steps are largely the same, explained a bit differently and in different sequence.

But they both outline a logical, step-wise process, ranging from "reversible" steps (such as Mozilla Safe Mode) to creating a whole new profile.





Please post back and let us know how it goes, so that we can all learn.

Hi,I done a scan with drweb cure it the other day and it found something in the temp folder which it neutralized and so far firefox is back up to speed so it must have been malware related.
