Firefox for Android becomes painfully slow over time. Clearing data fixes, but erases bookmarks. Where is the "Reset" function ??

After a fresh install, Firefox loads websites very fast with almost no lag. After a few weeks, it becomes slower and slower. Getting to the point where it wil take aboit 20 seconds to display the Top Sites/Bookmarks window. Then sometimes opening a page, the loading circle stops moving and it freezes the phone. After about 15 seconds everything works again. The only way I found to fix this horrendous problem is to go into control panel for Firefox and Clear Data. I dont like doing that because I lose all of my bookmarks. It seems the Cache always shows "0 bytes" so there never is nothing to clear out. I would like to know where this "Reset" function is for Android. I see they have it for Windows versions..but what about Android?

My phone is an HTC Rezound running stock Android 4.0.3 Thanks in advance.

Please update to version 19 to get the best performance of Firefox for Android.

This problem has existed in every know version of Firefox for Android since version 15 and earlier. I am very hesitant to update to the latest version because of numerous latest reviews of people having crashing problems with ver. 19. Thanks, but Firefox is the only browser I can use. Every other browser is barely useable since the ICS update on my phone.

Updating does not Clear data in the control panel, and in that data is what's causing the problem.

Speaking of data, here is just how much data Firefox is using.

You can try filing a bug for this issue at Bugzilla.

Ok, so I updated Firefox to version 19. I had a bad feeling about it but did it anyway. Grrr, I shouldn't have. Updated, and when I opened Firefox, it would not load anything at all. Just kept freezing. Would not go to a link nor would it ever load Top Sites/Bookmarks etc. Went into my task manager and seen it was using 50% - 75% CPU constantly. I went to End Task..but of course, Not Responding. Had to Force Stop in Control Panel. Tried loading Firefox again....SAME PROBLEM again. Froze. Force Stop again. Finally after 4 tries, I gave up. I had no choice but to Clear Data in Control Panel. Boy was I dam surprised when I viewed how much data it was using this time. I'll let the image speak for itself.

Of course, after clearing data it works now. But I lost all 30 of my bookmarks....GRRRRRRR

Hi Bruce0375

Really sorry to hear this. I wish I had a device that I can reproduce this problem with so I can work personally with development to get it fixed.

If you have filed a bug, please post the link here. If you haven't filed a bug, please do!

I am not using ICS and this could be totally unconnected, but I did have a problem updating to Firefox 19.0.2 on Android. /questions/952954

John99, I don't install to SD card since my Rezound has over 2gb of internal storage. But that last data storage number might make me re-think that.

Roland, no I have not filed a bug report. I was going to last night but not sure exactly what to file it under. Idk what this increasing slowness, lag and freezing are related to. I have seen the numbers in the data size go up and down. It seems the data size isnt the cause, but perhaps what's in the data heap. Corrupted data maybe.. I'll get back if I figure anything new. Bug time I guess......

Bruce,
whilst waiting for Roland to get back you may wish to try this

Enter into the address bar about:memory you get interactive dynamic information about memory usage, and maybe also about:compartments .

That should at least help you see where the memory is going to.
