Pontoon: Subpar matching in suggestions

Hi,

Take a look to this existintg string:

> Some websites use trackers that can monitor your activity across the 
> Internet. With Tracking Protection Firefox will block many trackers 
> that can collect information about your browsing behavior.
https://pontoon.mozilla.org/ca/firefox/all-resources/?string=152174

and this new string:

> Some websites use trackers that can monitor your activity across the 
> Internet. In private windows Firefox Content Blocking automatically 
> blocks many trackers that can collect information about your browsing 
> behavior.
https://pontoon.mozilla.org/ca/firefox/all-resources/?string=189818

Pontoon does not offer any machinery suggestion. Note the differences 
between the 2 strings (underlined):

> Some websites use trackers that can monitor your activity across the 
> Internet. _In private windows Firefox Content Blocking automatically 
> blocks_ many trackers that can collect information about your browsing 
> behavior.
[the new string is untranslated so that you can see that no suggestion 
is offered]

In my opinion, the existing string is a great candidate for a machinery 
suggestion but alas! the translator has to retranslate the whole string 
again. This is a major time waster. I've seen the same behaviour in 
other strings too.

If the string is considered to be too long for Pontoon's fuzzy matching 
process, please reconsider the length limit. It is precisely in long 
strings where the suggestions are more welcome. In my opinion, reusing 
existing translations should be a priority in Pontoon so that we do not 
feel that we are retranslating the same over and over again.

salut,
