Firefox 52. Problem with avito.ru

Post by t10raz »

Hello and sorry for my bad English.
On Firefox 52 some people in Russia have problem with site https://www.avito.ru/ This site is very popular in Russia. And since Firefox 52 was realeased, he works very slow in Firefox, but perfectly fine in other browsers. It's not only my problem.
You can check it on this video:
https://www.youtube.com/watch?v=YuC_39m ... freload=10
It's not problem with my system. Many people have this problem. One man even reinstall his OS, and this doesn't work.
Could you help with this problem?

I checked that site out in this loaded profile (lots of extensions) , my Test profile (1 extension) and in IE .... As far as I can tell the load-time in all tests came out pretty much the same... though my Test profile was the quickest because I use an ad-blocker...also, I disabled my ad-blocker in my Test profile and it did take longer and was loading and waiting on lots of 3rd party data injections.

you can see if this helps...
From a prior post from Dan Raisch (with minor changes) ...

(If using a version below Firefox 3.5.) Clear the browser cache (Tools->Clear Recent History->select cache->click on "Clear Now" button).

Else... use menu path Tools->Options->Advanced->Network tab->click on "Clear Now" button.)

Delete any cookies relating to the site(s) involved (Tools->Options->Privacy->Show Cookies button).
Note: The above is for Windows so if you're using a different OS refer to this...

Also... my ad blocker is...
uBlock Origin :: Add-ons for Firefox

Plus... your English is fine =D>

Not an answer, but if you disable JavaScript you'll see a world of difference.

about:config, javascript.enabled, set it to 'false'.
(Then set it back to 'true' after testing.)

Seems to run much better in an ancient version (38.0) of Chrome, so why it runs so poorly in FF is a good question.

Judging by your video, you have AdBlock Plus installed. What other addons are you using? Did you tweak any about:config settings? Avito works fine in Nightly with uBlock and NoScript, I don't see any slowdowns.

Avito works fine ... with uBlock and NoScript
As it does with JavaScript disabled.

(I can't run Nightly, but) restart in Safe Mode & see if you don't see very poor performance.

Now very possible that it is simply all the tracking/ad nonsense that might go on there, but if it were that alone, why does (ancient) Chrome (with no extensions) run acceptably?

After clicking on a city, such as https://www.avito.ru/sankt-peterburg
I see the extreme slowness with Firefox 52 ESR on Win XP.

The problem goes away with
network.http.spdy.enabled.http2 set to false (in about:config).

Maybe avito.ru should disable http2 for Firefox for now.

It's not my video. I don't have Adblock. I use temporary solution and downgrade Firefox to version 51 and Avito works very good.
This is very strange. Mozilla added in Firefox 52 something Incompatible with this site (which is popular in Russia).

Yes, security is the same. The reason for http2 is to make pages load faster!

Update 2017-03-24: Avito.ru has disabled HTTP/2 for Firefox 52. Speed looks normal.
