You mix in Fire Frys as easily with Warriors, in fact easier, as since they are smaller are even less visible to the enemy fire, which by the way is another bonus, smaller size.
Firefries and Blisters are both invisible if placed behind Warriors, there is no difference. The difference is that your entire Firefry Squad will be dead if hit by a firecracker, an underslung frag grenade or a Trip Hammer Mortar (be it direct or artillery fire).
Even a single PAMI Squad without any heavy weaponry is able to completely eradicate a Fry Squad in one shoot action - just drop them beside the Fries and have fun.
But you don't want to drop your Squad near a Blister Unit.
They may be not that fast as Fries but they are hard. You can place them in fireline of some Troopers without being sure they're all dead next turn.
Blisters are a bit like "small Tankers".
They have a powerful attack and still pack some serious armour - thus makes them perfect fire magnets.
And they are able to block an entire (terrain heavy) flank on their own (just supported by a small Warrior meat-shield), something Fries would never be able to do.
Fries are one-hit wonders and only capable of offensive moves.
Blisters are much more flexible. You can use them as firemagnet, heavy attack force, flank guard or heavy point blank defense.
Just imagine you are playing a scenario like sweep clean.
Place some blisters behind some rocks (in the table half the enemy is supposed to clear) and your enemy has a serious problem.
Place some fries behind a rock and they are dead from (underslung) grenades or Firecracker artillery once the enemy advances.
Place some Blasters there and the Exo Officer will walk in their Line of Fire, laugh and shoot them all.
So Blisters DO have their place and in most 'standard armies' I see them even more usefull than fries.
Fries excel when combined with fast moving bugs like Ripplers, Hoppers or Mantis. They are much less useful when put into a Warrior/Tanker-heavy army where they leave their supporting troops behind and get KIA long before the rest of the swarm arrives.
