To cut the long story short - my operator forces me to use some terrible toolbar with my dataplan (for data compression). This renders some webpages practically unusable.
I found a solution - on an Android forum someone stated that you only need to masquerade your browser as Opera. So - change the UAString (User Agent String).
How can I change this in Pre Plus Browser (and Google Maps - though it probably uses the Browser engine to render the webpages)?
