Avast Making Firefox Slow to Open?

For the last year it seems. firefox has been slow to open, 30 + seconds, then after it opens, it hangs for another 20 seconds.

been trying to diagnose it, and am wondering if avast might be the problem, maybe the web shield?

Is there a setting or something that will ‘allow’ firefox?

  • which avast! (Free/Pro/IS/Premier)?
  • which version…??
  • OS?..32/64 Bit…which SP?
  • other security related software installed?
  • which version of firefox?

TerraX

yeah sorry,

I’m on Win XP SP III,

FFox ver 31, and Avast free, 9.0.2021

windows firewall, I have SASpyware and malwarebytes, both free, but only run them on demand, no ‘active’ protection.

Do you ever cleaned up your machine with a cleaner (like CCleaner) and defrag it (free - Defraggler, Puran)? How many things do you have at Start Up? Anything that is not necessary, you can “Disable.”

How much memory on your machine?

Is your machine running normally otherwise? Do you have this problem in IE? FF has been adding more security features and depending on your add-on’s, it may be slowing things down. Do you have add-on’s that you don’t need? Are you using Tor?

Have your scans (both Avast and MBAM) been OK? BTW, the XP Windows Firewall is worthless. You may want to look into a free third-party FW for 2-way protection. Now you have 1-way protection. OA Free is light on your system, but you can also do a search here and find others compatible with Avast (e.g. Outpost, Comodo, etc.). But a lot depends on your memory and if you clean it or not. XP’s need to be cleaned and defragged.

Since Firefox has been my browser of choice for some considerable time and I have been using avast! for over ten years, I haven’t experienced that problem.

For some time now firefox has been opening in around 12 seconds. This actually improved somewhat in FF 31.0 and now opens in 11 seconds.

I have 28 add-ons and these actually have an impact on loading, so as SafeSurf mentions check your add-ons for redundancy. I currently have 9 pinned pages that will start loading once firefox has loaded/opened.

You don’t say what this 30 seconds covers, just firefox being displayed (loaded/open), as in my own example or also the loading of any pinned pages ?
The Web Shield only gets involved when you are loading pages, so presumably you too must have some pinned pages, again if you have look for redundancy, e.g. do you need all of them to load on firefox startup.

memory, is that the free space? That’s 58 GB, half the drive’s capacity.

yep do CCleaner once a week or so, and run the registry cleaner part every other week. Defrag every other week.

SASpyware works fine, but malwarebytes has been freezing up initially and I haven’t used it lately.

I’ve gone thru the startups, and unchecked quite a few.

I have 12 or so addons, most marked as ‘ask to activate’.

so, it takes 20 to 30 seconds for FFox to open and display a webpage, then another 15 to 20 for me to be able to do anything.

I never use IE but just tried it, 6 seconds to open and another 7 to be able to do anything. FFox always used to open faster then IE.

so in the web shield, is there any setting I can play with, to ‘allow’ FFox?

memory, is that the free space? That's 58 GB, half the drive's capacity.

No, it refers to the amount of RAM on your system. Right click My Computer > select Properties. Installed RAM will show at the bottom right.

it says 1.5 GB.
