Firefox has become very slow

When typing text, clicking or scrolling it takes about a second befor something happens. So this text appears on my screen with about 1 char/sec. Start-up and health report are normal. Loading a page takes ages. But once loaded scrolling should be no problem IMHO but it does. Internet is OK because, sorry, Internet Explorer hasn't any problem at all. Pentium-4, 3 GHz, Windows7-32, 2 GB RAM. I tried the refresh option and even reinstalled Firefox.

Any idea?

TIA!

Kind regards, Ruud Baltissen

Can you screen capture the Task manager while using Firefox so we can see what is all going on ?

Please see the uploaded image. As you can see yourself, nothing weird. BTW, if you don't understand the headres, we are Dutch. Some extra information: if I click "Help" at the top of the screen it takes some moments before the box appears and some other moments before the text appears. Moving the mouse to the left to "Tools", the new box appears, a second later the old one disappears and again a second later the focus is shifted from "Help" to "Tools". If you click "Options", it takes always eight seconds to build up the screen. And whatever changes, it happens in steps and every step needs a second.

I know it all sounds weird and I know that if somebody was telling me this I would think he was pulling my leg. If needed I'll try to video the whole phenomenon.

Many thanks!

Hello,

I restored a 5 months old backup of Windows and after the start the problem remained. Then I got the idea to use a copy of the version on my laptop and, hurrah, things worked as before. The version on the PC was 38.0.1, that of my laptop 37.0.2 But that lasted only a few minutes and suddenly this version became slow as well. Complete frustration of course :( So I decided to remove this directory and to use another copy. And this works fine for already half an hour.

So the one-million-dollar question: what is happening here?

For the moment I disabled all updates but if the momentary situation remains stable, I'll enable them again.

I hope this helped a bit....

Kind regards, Ruud Baltissen

See 124 MB seems normal. My mom just had to reinstall windows 7 32 bit and straight out of the box her Firefox with no add-ons as running at 750MB and she has only has 4GB memory

Me on the other hand to prove it mine is 127MB with a video page up Twitter, and 2 these pages.

Just yesterday I pointed out when I just open Firefox and nothing running 32.7 MB (2nd screen shot) and I have some 200 add-on.

win 8.1 64 bit 8 GB ddr3 memory

I notice a huge difference on memory usage between win7 and 8


How much memory and type of memory? 32 bit Windows?

I went to 64 bit Windows so I could add more memory.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

Because 37.0.2 works fine, I have to keep it that way. Main reason: it is not my computer but the one of my wife. She is more than glad it works now and she won't allow me to try "this or that".

Thanks anyone who helped me!

Kind regards, Ruud Baltissen

An addition: 37.0.2 becomes slow as well after some time: in average once a day. I made a little BAT file that deletes the original directory and copies one I have placed apart for this purpose. If it happens, the wife only needs to double-click an icon and things work fine again within seconds

Kind regards, Ruud Baltissen
