Lags and freezes with Firefox 27 or 28 beta with AIS Webrep 9.0.2013.75

Since a couple of months or a bit more, my two Firefox installation on two different PCs were experiencing sudden slodown, freeze to UI (locked task with grayed gradient), some occasionally slow transitions from a tab to another, slow loading of some complex pages (Gmail with Hangout plug-in) with Firefox (but no crashes at least); Opera and IE have no issues at all. I started searching info for this issue on Firefox forums…while yesterday I asked myself: “why not trying to disable AIS webrep on these two PCs?”.

Well, disabling WebRep on Firefox 26, 27 or 28 beta fix these issue (uninstall of this component not needed, just disabling it under firefox). Other Firefox Extension installed: ChatZilla 0.9.90.1, DownThemAll 2.0.16, Evernote Webclipper 5.9.1, Logitech Setpoint 6.5.1.

Any chance will you fix this slowdown with a new WebRep patch? Meanwhile I will keep Webrep disabled.

Keep in mind avast is not always compatible with beta software like FF betas or Chrome betas.
When they do become “final” releases that is when avast works well.

The “avast online security” add-on has been nothing but one great big headache/PITA
from the get-go. I don’t even have it (browser protection) installed. I rely on the three
resident shields. :slight_smile:

Btw, Firefox 28 is a beta actually. 27 is the stable version. Plug-in removed waiting for a more stable version

I have been having very similar problems, culminating with latest FF28 beta release - being literally unable to open any mails in my GMail last night. I therefore decided to go through the suggested FF troubleshooting :-
HW acceleration - already disabled
Plugins - all up to date except QT which I do not use
FF Safe Mode - no issues in GMail
Extensions - disabled all, then re-enabled/re-started FF one at a time.

My issue was definitely with the “Skype - Click to Chat” (surprise, surprise, a Microsoft product crippling a non-Microsoft one !!), disabled this and voila - all working fine. BTW, you can remove this insiduous parasite from add/remove, but it will be reinstalled every time you upgrade Skype - whether you want it or not !! So thanks for that crap Microsoft.

Hope this helps others in similar situation.
