Firefox painfully slow

Strange delays not only when rendering pages

My copy of Firefox gets painfully slow after some time of running it.

It will load pages with a delay (even busy-icon on the tabbar stops). Or if I use [Ctrl]+B to open the bookmarks-sidebar, it will do so with a delay of one or two seconds, sometimes even longer.

I have no other copy of mozilla-based-browser running when this happens, and this is my configuration:

Windows 2000
Firefox 1
Extensions: Adblock, Web Developer, Weatherfox, Prefbar, Tabbrowser Extension, BugMeNot, Stop-Or-Reload-Button

Since the delays are happening on just about any event (like opening a new tab, opening the sidebar, clicking a link, you name it), I suspect a computer-related problem, some weird things going on with memory and stuff. But, then again, it is also happening on my other machine which runs Windows XP Home.

My copy of Mozilla (1.7.3) runs perfectly fine.

Any ideas?

Did you uninstall any previous versions?

Yes, the system was clean before I installed FF1.

Try installing (or disabling) the extensions one at a time testing after each one.

Start with Tabrowser Extension, it's know to cause problems as it replaces some of Firefox's core code.

Thanks a lot. I now have deinstalled the tabbrowser extension. I will now use Firefox all day and see what happens. I'll report my findings later this day.

De-installing Tabbrowser and Web Developer extensions did not better the situation.

After de-installing Prefbar though, the browser seems to be back to normal.

I now will re-install the Tabbrowser and Web Developer extensions and see what happens, I'll report my findings later.

Anyone else found a similar problem with the Prefbar? I sure am going to miss this little gem.

Apparently Firefox 1.0 doesn't release resources when tabs are closed, so if you're opening and closing lots of tabbed windows it will soon start to kill your PC.

There was a thread on Slashdot about this over the last day or so, so if it wasn't a known bug it is now.

After a day of using FF 1 without the preferences toolbar, I suspect this extension to have been source of the problem. FF 1 now runs smooth and super-fast.

I replaced the tabbrowser extension with the tabbrowser preferences extension, as this contains all I need. My test did not reveal any problem with the tabbrowser extension, but I thought I add it here anyways.

I did no further research so far as if the preferences toolbar extension itself was the problem or the settings I made. Mozilla 1.7.3 runs smooth with it. I just wish my one-click access to activation/deactivation of javascript, cookies, flash and stuff back. Seems I need to find another extension for this, or write one myself *shudder*.

2 options, try a 3rd party build/unofficial build here: Notice the Today's build in the first thread [forums.mozillazine.org] that is if you like Firefox.

But if you would rather still use the Gecko rendered core in a browser you really need to try this one it is in beta transision but up to date there are no fatalities (crashes or berserk failures): When you click on the link it is an instant exe to your desktop which will show you were it is, you can put it in another directory if you like.
